OSB sheathing. How to make a pediment from an OSB board (OSB): a step-by-step description of the cladding process

In order to paint OSB with high quality with your own hands, you need to take a responsible approach to choosing the mixture.

Dye

Several types of material can be used.

Organosoluble

One of the simplest and most popular solutions, the composition provides fairly high adhesion to the surface of OSB panels. Traditional options:

Oily. Coloring with such mixtures is widespread, although in recent years it has been declining. This is explained by the fact that the products are quite toxic and have a pungent odor. The resulting coating has a service life of 3–5 years, after which it fades and loses its decorative qualities.

Alkyd. A universal variety that allows painting inside and outside the premises. The treated surface has a bright and saturated color, persisting for a long time. Compared to the previous version, enamel is more resistant to any weather conditions, but is not environmentally friendly and has a wide decorative range.

Water-based

The most modern products with high aesthetic and performance qualities. For processing OSB, compositions with a polymer component are used. This list includes:

Acrylic. The mixtures are absolutely safe, UV resistant and easy to apply. When working with particle boards, water-based compositions require high-quality priming and application of the solution in thin layers. It is necessary to prevent excessive moisture absorption, otherwise the panel may swell.

Latex. Painting a surface with such a mixture is quite simple; the material has almost the same advantages as the previous one, but is more expensive. This includes the rubber variety, ideal for outdoor use.

Primer-paint

On a note! When choosing a composition for different processes, it is better to give preference to certain categories, even taking into account the fact that many mixtures are universal. This is especially true for facade work, so in such a situation it is advisable to purchase special solutions.

Primer

Due to the fact that most often for cladding internal structures For the premises and façade, OSB-3 boards are used, which have low adhesion due to additional treatment against moisture penetration; priming is a mandatory procedure. In addition, this significantly reduces paint consumption and reduces the likelihood of deformation when choosing water-based compositions.

The following varieties are suitable for this work:

Drying oil. This is a simple solution if you plan to use oil paints.

Concrete contact. Although any modern polymer-based compositions classified as deeply penetrating can be used, this mixture is optimal. It fits well on the surface and impregnates it, forming a rough layer that provides the best adhesion.

Concrete contact primer is used to ensure maximum adhesion of paint to the OSB surface

After laying and drying any type of soil, it is necessary to quickly treat the base with decorative or protective materials. During this period, adhesion is maximum.

Impregnation

The following varieties are used:

Like drying oil, it helps protect the material from the harmful effects of water, preventing rotting. Although the outside of the building is sheathed with moisture-resistant products of classes 3 and 4, OSB-2 boards are most often found inside; they are processed separately. Stain is also applied as a decorative layer when covering panels with varnish.

If you want to preserve the texture and give the slab a noble red tint, stain is used

Fire retardants. They are recommended to process all sides and ends of parts before installation. Fire retardant impregnation reduces the likelihood of fire and also increases the time during which the material will be flame resistant.
Antiseptics. Such protection is required to prevent the appearance of mold and mildew, which are most often caused by dampness.

Important! Particular attention must be paid to the ends of parts located outdoors. They are impregnated more thoroughly, since it is in these places that the destruction caused by the harmful effects begins environment.

Varnish

This composition is more suitable for indoor work. For floors or ceilings, colorless varnish is more often used to ensure preservation natural look material. To enhance the ambience, well-defined wood chips can be treated with a stain of a suitable color, which is not just applied, but literally shaded.

To convey the texture of natural wood, colored varnishes are chosen. But the structure of the panel is extremely heterogeneous, so obtaining a uniform coating will not be so easy, regardless of the chosen paint and varnish mixture. The desired result can be achieved by painting the base 3 to 6 times.

Colored varnishes can imitate a variety of wood types

Features of painting OSB boards outside

Work on the street involves the creation of a decorative layer, which will also play a protective role. For the process you will need a simple list of tools, suitable for covering walls inside the house:

Spray gun. For each composition, the desired option is selected.
Paint roller. It is better to provide several replaceable nozzles.
Tassels. For work in hard-to-reach places.

Everything you need is purchased in advance.

Surface preparation

Before installing the sheets, high-quality impregnation of the ends of the parts is carried out. Further actions:

After all processes are completed, the facade is left to dry completely.

Applying paint

You can cover the prepared surface with the selected solution according to the following scheme:

If necessary, the composition is diluted to the desired consistency. To spray, it must be more liquid, but because of this the number of layers increases and the consumption increases significantly.
The solution begins to be laid from top to bottom in a single layer.
The pronounced dark areas that appear are left, they are eliminated only evenly and consistently.
Next, layer by layer is laid until the desired result is achieved. After each treatment, the base dries out.

If you carry out all the steps without haste, you will end up with a coating with a slightly protruding texture of wood chips.

Painting slabs indoors

The process can be performed in two ways, depending on preference. But preliminary preparations are carried out, almost similar to those for external areas. The only difference is that moldings are not used to hide seams inside the house, unless provided for by the interior design.

Classic method

This method involves simply applying OSB paint to the wall surface. After preparing the base, the decorative mixture is mixed and applied evenly and sequentially in several layers to all treated areas. If putty was previously used, the painted surface will be uniform, but if it is absent, a strong or weak texture will be observed, depending on the amount of material applied.

Painting OSB without prior puttying allows you to preserve the texture of the material

It is much easier to treat the floor: after sanding, it is prepared and covered with 4-5 layers of clear varnish.

Decorative method

To decorate the base of oriented strand panels beautifully, you can use various techniques. For example, aging of the coating. Instructions:

The slabs are carefully sanded and primed until smooth.
Acrylic patina is being prepared. It is quickly applied to the desired areas or the entire surface. The longer the mixture sits on the base, the richer the color becomes.
The solution is wiped off with a rag.
Next you need to paint the material light shade to highlight darker areas.

An alternative method could be easy installation several colors, but each subsequent layer should be “softer” than the previous one.

Caring for painted OSB

With the right choice decorative composition and following the preparation and application technology, further procedures will be as follows:

After 5-7 years (depending on the composition), a light treatment with a thin layer of diluted solution can be performed to revitalize the surface.
Significant difficulties arise due to the shrinkage of the house; more serious reconstruction may be required. But if the frame was positioned accurately, observing the gaps, then you will only need to rearrange the moldings on the outside and minor finishing work on the inside, followed by painting in the desired color.
Shabby flooring re-sanded and varnished.

Painting OSB is not the most difficult process, requiring accuracy and a precise sequence of all actions to obtain a high-quality result.

Material selection

There are several types of materials that more or less meet these requirements: moisture-resistant plywood, fiberboard, OSB, edged boards, fiberboard. They have similar characteristics and are widely used in frame construction. To make a choice, it is worth familiarizing yourself with the main properties and features of each of them.

Application of OSB in frame construction

OSB panels are rightfully among the most popular materials in the construction of frame structures. They consist of layers of glued wood shavings and wood chips, with the fibers located longitudinally in the outer layers and transversely in the inside. For fastening chips are used synthetic resins and wax, which gives the finished slabs water-repellent properties.

Standard production involves the production of these slabs in several categories:

OSB-1 is intended exclusively for interior decoration of dry rooms with reduced mechanical loads;
OSB-2 is used for installation load-bearing structures in rooms with low humidity;
OSB-3 is a moisture-resistant board of increased rigidity used for the installation of load-bearing structures indoors and outdoors.

Cement particle boards

This material is a compressed mass of M500 cement and shavings (usually coniferous species). A standard slab has three layers: the outer ones are made of small chips, the inner one is made of large ones. In addition to the main components, the composition contains hydration additives, the mass fraction of which does not exceed 3%. DSP is characterized by moisture resistance, high strength, long term services. The slabs are widely used in private and industrial construction, for indoor and outdoor work.

Gypsum fiber sheets (GVL)

Moisture-resistant gypsum fiber sheet

GVL consists of pressed gypsum reinforced with cellulose fibers. Due to its high strength, the material is suitable for creating load-bearing surfaces, therefore it is widely used in frame construction. It differs from plasterboard in its greater density, uniformity, and absence of a cardboard shell. In terms of frost resistance, sound insulation properties, as well as resistance to moisture and combustion, gypsum fiber boards are also several times higher than gypsum boards.

Installation of gypsum fiber boards is carried out using frame and frameless way. For external wall cladding, the first option is used, where the sheets are fastened to the load-bearing posts using self-tapping screws. The material is easy to cut and drill, and, despite its heavy weight, is quite convenient to install. This cladding serves as an excellent basis for finishing with tiles and decorative plaster.

Construction of a frame house

Sheathing can be done in two ways - with and without lathing. In the first case, the vapor barrier layer is located between the frame and the OSB, in the second - on top of the sheathing. The option with lathing is used in cases where OSB acts as a basis for plastering, painting or tiling; the second method is used, as a rule, when installing a ventilated facade. Otherwise there are no significant differences.

Step 1. Start covering from the very corner. The first sheet of OSB is applied to the frame posts so that the bottom edge completely covers the bottom trim of the house. Be sure to check the horizontal level. It is also recommended to install the slab itself horizontally rather than vertically - this provides the structure with greater rigidity. To fasten the material, galvanized self-tapping screws with a length of at least 50 mm are used. It is necessary to retreat about 10 mm from the edge of the OSB, the fastening step along the perimeter of the sheet is 15 cm, in the center - 30 cm.

Step 6. Next, the sheathing slats are stuffed for finishing in increments of 50-60 cm. The slats must first be treated with a protective compound and dried. After this, you can begin installing siding, lining or other decorative covering for the house.

On a note! If you plan to paint a facade made of OSB, then the membrane, accordingly, is mounted only with inside Houses.

With this method of cladding, the insulation is placed on the inside of the walls in the cells of the frame and closed vapor barrier film. Slabs for interior decoration, for example, plasterboard or the same OSB, are sewn on top of the vapor barrier.

Video - How to sheathe the outside of a frame house

OSB (OSB) or OSB (oriented strand board) is a modern structural material that has become a serious alternative to plywood, chipboard and has found wide application in the construction of frame houses and the finishing of buildings and structures. OSB boards are used to cover interior and exterior walls, floors and roofs. Wall cladding with OSB boards takes place in frame construction, when the board acts as a structural material and serves to strengthen the walls of a building, or when it acts as a facade material for concrete, brick or wooden houses, which is caused by the low price and high strength and durability of the material. In this article we will look at the question: how to attach OSB boards to the wall from the outside.

For cladding external walls, it is necessary to use OSB-3 boards, specially made for environments with high humidity. You can find out how different types of OSB sheets differ on the page: OSB sheets, their types, characteristics, sizes.

When installing OSB boards to external walls, sheathing is used for the following purposes:

leveling the wall plane;
creating a ventilation gap for insulation under the OSB board;
preventing slab deformation caused by base movements, especially important for OSB slabs with a thickness of 9 mm or less.

Fastening OSB boards to the wall over insulation using lathing

Fastening the slab to the wall is carried out using lathing, which is made from a wooden block, or metal profile. The technologies for installing OSB boards on a wall with wooden sheathing and sheathing made of metal profiles are not fundamentally different. When choosing a block, it is advisable to choose a dry, planed block of 40-50 mm, then it will not twist or move after drying, which will have a positive effect on the evenness of the entire wall.

To attach the bar and profile to the wall, special metal plates (hangers) are used. Before attaching the hangers, it is necessary to draw vertical stripes on the wall, the distance between which should be half the width of the sheet, which will subsequently ensure the joint of the slabs right in the middle of the bar or profile and will make it possible to fix the OSB slab in the center along its entire length. After the lines are drawn, hangers are attached along them in increments of 30-40 cm.

A metal hanger is used to fasten the sheathing. The hangers are attached along the marked lines. Hangers allow you to secure the sheathing over the insulation.

After this, the insulation is laid and covered with a membrane that protects the insulation from moisture, after which the sheathing is installed.

It should be noted that a vapor barrier is not needed outside the building, since it prevents moist air from entering the insulation from inside the room, and outside structure, excess moisture should freely escape outside.

Wall with sheathing. Insulation is laid between the sheathing and the wall.

After securing the sheathing, you can begin installing the OSB boards. For wall cladding, a slab with a thickness of 9 to 12 mm is most often used. If a facade is not mounted on top of the slab, then the slab must be moisture resistant. OSB slabs are attached to the wooden beam sheathing with nails at least 2.5 times longer than the thickness of the OSB sheet. For metal profile sheathing - use metal screws 10-15 mm longer than the thickness of the OSB sheet.

With this installation, the sheathing weighs above the insulation and does not create cold bridges in the insulation between the wall and the OSB boards. Thanks to this solution, maximum efficiency of the insulation is achieved. In addition, between the beams of the sheathing there is an air gap through which moisture is removed from the insulation, which also improves its characteristics. More detailed information about the technology of ventilated facades is in the article: ventilated facades, types of ventilated facades.

Fastening OSB boards to a wooden frame

When building frame houses with a wooden frame, two main approaches are used: fastening OSB sheets to the frame through the sheathing and attaching OSB sheets directly to the frame without sheathing. Let's consider the case of fastening OSB boards using sheathing.

When strong slabs are attached to the frame on the inside of the wall, ensuring good rigidity of the wall structure, then a sheathing can be made on the outside between the frame and the OSB board. The sheathing forms air cavities for ventilation of the insulation and reduces the deformation loads from the frame to the OSB board.

Insulation is placed between the frame posts. A wind and waterproofing membrane is attached over the studs and insulation, which easily allows moisture to pass through. Next, the sheathing and OSB boards are attached to it.

Installation of OSB boards on wooden frame with sheathing.

With this design, the slabs can be left without finishing; you can paint them, plaster them, or attach almost any material to them. facade material.

When fastening OSB boards without using sheathing, maximum rigidity of the wall structure is achieved. In this case, it is recommended to attach the wind and waterproof membrane behind the OSB board, then install the sheathing to create a ventilation gap and install facade material on it, such as siding, boards or decorative panels. OSB boards are attached to a wooden frame with nails at least 2.5 times longer than the thickness of the OSB sheet.

The advantage of using nails over self-tapping screws when fastening OSB on the outside of a house is justified by the fact that nails better tolerate deformation of OSB sheets under atmospheric influences.

Technology for attaching OSB sheets to a wooden frame without using sheathing.

For example, when building a frame house using the Finnish “Platform” technology, there is no sheathing between the frame and the OSB frames. You can find out more about this technology in the article: construction of a frame house using the “Platform” technology.

Fastening OSB boards to a metal frame

Fastening is carried out similarly to the option with a wooden frame. When attaching slabs directly to a metal frame, use metal screws 10-15 mm longer than the thickness of the OSB sheet.

General rules for installing OSB boards to the wall

Regardless of the chosen method of fastening OSB sheets, there is general rules, compliance with which will ensure maximum strength, reliability and durability of the cladding structure.

Self-tapping screws should be screwed in at a distance of 10-15 cm from each other and at least 1 cm from the edge of the slab.
A 10 mm gap is required between the bottom slab and the foundation to prevent water accumulation.
The slabs cannot be joined closely to each other; a gap of 2-3 mm is required between them so that the slab can expand freely due to changes in humidity.
All door and window openings are cut with a jigsaw or circular saw, but if you need perfectly even joints and cuts, then you can come to furniture workshop, where for a small fee they will cut your sheets on a sawing machine evenly and precisely to size.

Which side to mount OSB sheets

All sides of OSB sheets do not differ in composition. But there are differences in the surfaces. Often one side is smooth and the other is rough. In this case, when installing slabs on walls on the outside of a building, it is better to mount the sheets with the smooth side out. With this orientation rainwater will not accumulate in such quantities in the unevenness of the slab. Water helps accelerate the destruction of the slab. Protecting sheets from water penetration helps increase their durability.

When installing slabs on the roof under the roof, in turn, it is recommended to place OSB sheets with the rough side up so that they are not slippery to walk on during roof installation work.

When installing OSB boards in places protected from moisture, the choice of their orientation does not have a significant impact on subsequent operation.

Read the contents of the article! Decorating the outside of a house with OSB: methods for finishing OSB sheets: painting, plaster, artificial stone, siding.

OSB boards or otherwise OSB sheets are widely used for the construction of walls in houses, in particular in frame construction. Therefore their question exterior finishing very relevant today. Moreover, not only from an aesthetic point of view, but also in terms of protecting the material from negative impact external factors (high humidity, sudden temperature changes, solar radiation and others).

In this article we will look at the following question: OSB finishing on the outside Houses.

Finishing OSB outside Finishing walls from OSB boards outside the house: how to finish OSB walls

There are many different ways to decorate walls made of OSB sheets outside the house. All of them take into account the features of OSB boards, which are subject to the same deformations as wood.

Among the main methods used for external finishing of walls made of OSB sheets are the following:

Painting a house made of OSB

Painting is the simplest and most common option, which does not require a lot of time and money. Water-based or oil-based wood paints are used for exterior work. In order for the coating to adhere well, it is important to properly prepare the surface for painting. First of all, it is recommended to seal interpanel seams acrylic sealant, and then thoroughly clean and prime the entire surface of the slabs. The paint is applied in several layers. Each of them must be given time to dry thoroughly before applying the next layer.

Painting OSB boards

To paint OSB boards, you can use a brush or roller.

Applying plaster to pox boards

Plaster allows you to extend the life of the slab and additionally protects it from fire. OSB boards can change their geometric dimensions over wide ranges due to changes in humidity and ambient temperature. If you apply plaster directly to OSB plate, then soon it will become covered with cracks and peel off from the base. Therefore, two main technologies are used: the use of an intermediate layer and layer-by-layer application of plaster.

Plaster OSB boards

Expanded polystyrene or glassine can be used as an intermediate layer. Expanded polystyrene has good moisture insulation and further improves the thermal insulation properties of the wall. Glassine or bitumen cardboard has a low price.

To prepare the base, sealant is applied to the joints between the sheets. The sheets themselves are primed. After this, an intermediate layer in the form of polystyrene foam or glassine is glued. A reinforcing mesh is attached on top of this layer and a layer of plaster is applied.

When applying plaster directly to OSB sheets, the process is divided into several stages. After preparing the base, as in the previous version, proceed to the first stage. During which the first layer of plaster is applied, a reinforcing mesh is embedded in it. After drying, apply another layer. After this, a leveling layer is applied.

The option without an intermediate layer is less reliable and after 2-3 years the plaster may begin to peel off, so it is usually recommended to use an intermediate layer.

Installation of decorative stone on osb boards

Artificial stone is one of the most complex and expensive finishing methods. However, the excellent appearance of the finished facade and the durability of such a coating will certainly pay for itself over time. Stages of work:

Before starting work, the seams of OSB boards are filled with frost-resistant sealant, and the boards are primed.
Polystyrene foam is glued on top.
Then it must be filled with frost-resistant putty.
Then apply two layers of glue. Place the reinforcing mesh into the first one.
Place on the second layer decorative rock.

Finishing OSB boards with decorative stone

Sometimes decorative stone is glued without an intermediate layer in the form of polystyrene foam. This option is less reliable and after 2-3 years the coating begins to peel off.

Fastening siding to OSB boards

Siding – universal method finishing that can be used for any facade. The material has an affordable price and excellent appearance. Provided that the OSB board has flat surface, fastening the sheathing is optional. At the same time, so that during operation the material does not swell from the condensation formed, it is important not to forget to install a windproof, waterproof membrane between the slabs and the siding.

Finishing OSB boards with sidingDecorative facade panels

Decorative facade panels have a wide range of modifications and are manufactured using various materials: wood, metal, plastic, glass. The technology for installing such panels depends on the panels themselves. Most often used for fastening: dowel fasteners, brackets and metal profiles.

Installation decorative panels on the walls of a house made of OSB

Each of the listed methods has its own advantages and disadvantages. It doesn't matter which one you choose. The main thing is to strictly adhere to the recommendations of specialists and the correct technology.

Covering a frame house with wood planks

After the final construction of the frame house, installation of windows and doors, as well as installation of insulation on the walls, it’s time to move on to the next stage - surface cladding frame structure. At this stage, every master faces the question: what materials to use? You can use lining, siding, natural wood, ventilated facades or vinyl panels.

The best option in terms of appearance, price, durability and resistance is the use of siding and wood panels.

Before cladding the outside of a frame house, you need to do preparatory work.

First of all, you need to prepare the lining with a maximum permissible humidity within 10-15%.

If the humidity is higher, after installing the panels, the wood will begin to shrink, which will lead to deformation, displacement of the boards and the formation of numerous cracks.
It is recommended to carry out the cladding of a frame house in late summer or early autumn - at this time the effect of sunlight is not as intense as in June or July.

Thus, purchase wooden boards necessary several months before the work, approximately in May-June. This is necessary for sufficient drying of the wood, which lasts at least six to eight weeks.

After drying and preparing the materials, you can begin sheathing. Work is carried out from the bottom up. The second panel is positioned with the groove up, while the tenon points down to secure it with the starting board.

Expert opinion

Ask a question to an expert

The boards must be laid strictly horizontally - a building level must be used to check the position.

The second board and those following it are secured as follows: the tenon is inserted into the groove, after which several blows are applied to the top board with a mallet to fix it. The blows must be applied carefully so that the walls of the grooves are not deformed. Along the edges of the panel, at a distance of 10 mm, the board should be secured with two nails.

The entire panel must be nailed along its length, with a pitch of 500 mm.
After the frame house is covered with wooden panels, two boards must be secured in the vertical direction at the outer corners, overlapping each other. In the same way, platbands are installed on window and door openings.
The outer cladding of a frame house can be carried out both horizontally and vertically.
After installing the wood panels, you can begin painting. Before this, it is necessary to prepare the surface of the walls so that in the future they will not be rough or uneven. For this purpose it is used Sander with installed abrasive size 25-120. Alternatively, an abrasive with an index of 40 can be used.

If painting with oil paint is carried out, then before applying it you need to cover wooden panels two layers of drying oil. Only after this can the surface be painted using a roller, spray gun or wide brush.

Covering a frame house with siding

Siding panels have special perforated edges with slots through which they are attached to the surface using nails or self-tapping screws. There is a hole on the bottom of the siding panel to drain condensate.

The master will need the following tools:

Connecting strips
Plastic siding
Building level
Kiyanka
Corner

You can cover it with siding using connecting strips, but to save money you can make an overlap connection without using strips.

Initially, preparatory work is carried out. Siding can be attached in several ways: either on aluminum profiles, or directly on the surface of the walls.

Alternatively, instead of aluminum profiles, you can use ordinary wooden blocks attached to the surface of the walls. This method of saving will allow you to save up to 30% of the funds that could be spent on cladding with aluminum frames.

After laying the wooden blocks (or installing the aluminum frame), sheathing can be carried out. On bottom corner The starting strip is installed on the sheathing (at the same time it is checked with a level for horizontal position).

Once the panel is level, you can attach it to the studs using nails or self-tapping screws. The installation of the panels is carried out as follows: one of the ends of the product is inserted into the groove of the corner, after which the profile tenon is inserted into the groove of the starting strip.

This type of connection is called a “lock” - if all actions were carried out correctly, the technician will hear a characteristic click, indicating the success of the connection.

The perforated edge of the siding panel has slots that are designed to secure the panel to the wall surface using screws or nails. After successful fastening, you can install the second panel overlapping the first.

The outer cladding of the house with siding is carried out from the bottom up: first, starting strips are installed around the perimeter, then the second panels, third ones, etc. are installed.

Sheathing a frame house with OSB boards

OSB boards can also be used for cladding a frame house.

Oriented strand boards are made from wood chips that are pressed together under pressure and coated with synthetic resins. The main material of OSB boards is pine or spruce.

The slabs are fastened directly to the walls; no additional frames or connections are required.

Sheathing is carried out as follows:

Work is carried out from the bottom up. After installing the first slab (and measuring the level), the second slab is installed. Must be left small expansion joint(2-3 mm) so that in case of expansion building material no deformation occurred
Self-tapping screws are installed at the junction of the panels, which act as limiters. The length of the screws must be at least 50-55 mm.
Nails or screws are mounted at a distance of 1.5-2 cm from the edge, a step of 15 cm is maintained. Closer to the middle of the panel, the step can be increased to 30 cm

Sheathing using OSB boards is not only structural reliability and strength, but also significant savings on installation costs.

The main types of building materials for such structures are wooden beams, beams and OSB panels. It is the use of panels that provides a frame house with those characteristics that attract developers so much.

Houses built according to frame technology, have beneficial advantages. But, as reviews show, these advantages can only be achieved with full compliance technological process.

Final stage of work

In order to give a frame house more aesthetic appearance, it is recommended to install a finishing strip on top of the walls, and a plastic corner on the area between the pediment and the cladding. It will help to correctly and securely fix the bottom strip, as well as hide the visible joint of the panels.

To ensure that the ends of the panels are not noticeable, you can use finishing window openings plastic corners instead of wooden frames. One side of the corner is fixed near the window opening, and the other side will hide the visible ends of the panels.

If you have already chosen required material and prepared the tools, you can begin the initial preparatory work. We wish you successful construction.

Requirements for external cladding materials

External wall cladding is one of the final stages of building a frame house. And here the choice of material is of great importance: the microclimate in the premises depends on it, mechanical strength walls, reliable protection from moisture and cold. In addition, the cladding serves as the basis for finishing materials, and in some cases acts as a finishing coating and is responsible for the aesthetic appearance of the building.

The cladding gives the building frame a certain rigidity and takes on part of the load. This means that one of the main criteria is the mechanical strength of the material in bending and compression, and the absence of shrinkage during operation. The walls must retain their original shape for years, regardless of environmental conditions. In addition, the cladding must be resistant to moisture, sudden temperature changes, and the effects of microorganisms.

Next, you need to pay attention to the ease of installation of the material and its flexibility during processing. If you plan to sheathe it yourself, this aspect is of great importance, because it determines how much effort and time the work will require. The material should be easy to cut and drill, but at the same time maintain density in cuts, not crumble, not crack. And, of course, it must be durable so that you don’t have to change the skin every 10-15 years.

Material selection

There are several types of materials that more or less meet these requirements:

moisture resistant plywood,
edged board,

They have similar characteristics and are widely used in frame construction. To make a choice, it is worth familiarizing yourself with the main properties and features of each of them.

Oriented Strand Boards (OSB)

OSB panels are rightfully one of the most popular materials when arranging frame structures. They consist of layers of laminated wood chips and chips, with the fibers in the outer layers arranged longitudinally and transversely in the inside.

Synthetic resins and wax are used to hold the chips together, giving the finished boards water-repellent properties.

Standard production involves the production of these boards in several categories: OSB-1 is intended exclusively for interior decoration of dry rooms with reduced mechanical loads; OSB-2 is used when installing load-bearing structures in rooms with low humidity; OSB-3 is a moisture-resistant board of increased rigidity used for the installation of load-bearing structures indoors and outdoors.

In terms of the quality-functionality-price ratio, OSB-3 is the most optimal, and this material is widely used in private construction for wall cladding, the manufacture of load-bearing partitions, and reusable formwork when pouring concrete structures. The slabs lend themselves well to grinding, cutting, drilling, and hold nails tightly even at a distance of 6 mm from the edge. Such cladding can simultaneously serve as a decorative covering for walls; you just need to treat it with waterproof varnish or paint it.

Advantages of OSB:

the dense structure prevents delamination and splitting of the material during processing and during operation;
the plates have elasticity and high strength, excellent resistance to vibrations, compression loads, and various deformations;
the material is resistant to weathering and temperature changes;
OSB is resistant to microorganisms; insects and rodents do not like it.

Flaws:

very low vapor permeability;
flammability;
content of toxic compounds (phenol and formaldehyde).

Cement particle boards (CSP)

This material is a compressed mass of M500 cement and wood shavings (usually softwood). A standard slab has three layers: the outer ones are made of small chips, the inner one is made of large ones.

In addition to the main components, the composition contains hydration additives, the mass fraction of which does not exceed 3%. DSP is characterized by resistance to moisture, high strength, and long service life. The slabs are widely used in private and industrial construction, for indoor and outdoor work.

When covering a frame, such slabs serve as an excellent basis for cladding, decorative plaster, painting, because they form a perfectly flat and smooth surface. The material can withstand 50 cycles of complete freezing and thawing without losing its characteristics; subsequently, the strength of the slabs decreases by about 10%. Among wood-based panel materials, DSP is a leader in terms of environmental and technical indicators.

Advantages:

very low hygroscopicity;
resistance to mold and other microorganisms;
DSP are not damaged by insects and rodents;
the material does not emit toxic substances;
low thermal conductivity;
Fire safety.

Flaws:

mechanical processing of plates requires significant effort;
DSP is heavy compared to other materials;
When cutting and drilling slabs, a lot of fine dust is generated, so you need to work in a respirator;
high price.

Fiberboard (Fiberboard)

The material is sheets of compressed shavings, usually coniferous. During the pressing process, the raw materials are highly heated, which makes it possible to achieve maximum density without the use of adhesives. Thanks to this, fiberboard is environmentally friendly clean materials, and therefore suitable for outdoor use and for finishing residential premises. The shavings contain natural resin, which acts as an antiseptic and protects the slabs from mold.

In terms of strength, fiberboard is noticeably inferior to natural lining and OSB, but it surpasses them in heat and sound insulation properties.

Now on the construction market, fiberboards are represented by insulating boards of several well-known brands, the most popular of which are Beltermo and Izoplat. For cladding a frame house, slabs with a thickness of at least 25 mm are used; thinner sheets are used indoors.

Advantages:

light weight;
low thermal conductivity;
ease of installation;
the material does not delaminate or crumble; high vapor permeability;
resistance to moisture and microorganisms;
absence harmful substances in the composition.

Flaws:

high price;
a long stay without decorative finishing causes slight deformation of the sheets;
The outer lining of fiberboard requires spacer jibs in the frame or rigid inner lining.

Gypsum fiber sheets (GVL)

In terms of frost resistance, sound insulation properties, as well as resistance to moisture and combustion, gypsum fiber boards are also several times higher than gypsum boards. GVL installation is carried out using frame and frameless methods. For external wall cladding, the first option is used, where the sheets are fastened to the load-bearing posts using self-tapping screws. The material is easy to cut and drill, and, despite its heavy weight, is quite convenient to install. This cladding serves as an excellent basis for finishing with tiles and decorative plaster.

Advantages:

low hygroscopicity;
vapor permeability;
absence of toxic compounds;
fire safety;
high heat and sound insulation properties.

Flaws:

lack of ductility and fragility when bending the sheet;
heavy weight.

Plywood

Plywood is made by gluing together thin sheets of veneer from various types of wood (most often coniferous and birch). The sheets are laid perpendicular to each other relative to the location of the fibers, which helps to increase the mechanical strength of the material and increases resistance to deformation. For the outer cladding of frame walls, plywood with increased moisture resistance is used, which is marked FSF. The thickness of the sheets should be from 9-10 mm; thinner material will not provide the required rigidity to the frame.

The grade of plywood is not particularly important for sheathing, and you can use the cheapest unsanded 4/4 grade boards.

From the outside, all defects will be hidden under the curtain wall, so there is no point in overpaying. If the cladding technology is followed, the plywood covering will serve for years without losing its qualities.

Advantages:

high bending and compressive strength;
moisture resistance;
wear resistance;
ease of processing and installation;
frost resistance.

Flaws:

flammability;
content of formaldehyde resins;
tendency to chipping.

Edged board

Application edged boards for cladding is the most economical option. Wood is an environmentally friendly material, affordable, and easy to install. Boards can be filled not only horizontally, but also at an angle of 45-60 degrees. To save material, boards can be fastened in increments of up to 30 cm, although more often the sheathing is made continuous. This design perfectly strengthens the frame and is a ready-made base for a ventilated façade.

In order for the cladding to be reliable, boards should be chosen with a thickness of at least 25 mm; they can be tongue-and-groove for greater joint density. You cannot use raw lumber: during the drying process, the wood will begin to warp, and deformations of the finishing coating may appear.

Advantages:

wood does not emit harmful substances and has excellent vapor permeability;
boards are easy to process;
the work does not require large financial costs.

Flaws:

flammability of the material;
wood is susceptible to damage by insects and microorganisms;
Fitting and fastening elements takes a lot of time.

Exterior cladding technology

Installation of slabs on a finished frame is carried out using the same technology, regardless of the type of material. Simultaneously with the sheathing, vapor barrier and wall insulation are carried out, and finishing can be done immediately upon completion of construction or after some time. Let's look at the installation technology using the example of covering a frame with OSB boards.

Step 1.

Start covering from the very corner. The first sheet of OSB is applied to the frame posts so that the bottom edge completely covers the bottom trim of the house. Be sure to check the horizontal level. It is also recommended to install the slab itself horizontally rather than vertically - this provides the structure with greater rigidity. To fasten the material, galvanized self-tapping screws with a length of at least 50 mm are used. It is necessary to retreat about 10 mm from the edge of the OSB, the fastening step along the perimeter of the sheet is 15 cm, in the center - 30 cm.

Advice. To firmly fix the slabs, the length of the hardware must exceed the thickness of the OSB by at least 2.5 times. If the self-tapping screw enters the frame beam less than 30 mm, under the influence of loads the sheathing will begin to tear away from the supporting base.

Step 2.

The next plate is installed next to the first, leaving a gap of 2-3 mm for thermal expansion. In the same way, set the horizontal level and screw the casing to the frame guides. The joints of the plates must be in the middle of the rack, only in this case the fastening will be as reliable as possible. Fix the remaining slabs in a circle, leaving open areas for doorways.

Step 3.

The second row of sheathing must be installed with ligation of vertical seams. The same gap of 2-3 mm is maintained between the lower and upper plates. When sheathing openings, you should use whole sheets, not scraps - the fewer joints, the more airtight the sheathing. Cutouts in the sheets are made with a jigsaw or a circular saw, having previously made markings accurate to the millimeter. The edges of the cuts after installing the slab should perfectly coincide with the lines of the openings.

Step 4.

The top plates are installed so as to completely cover the top trim. If the house has two floors, the interfloor piping should be closed in the middle of the slab - under no circumstances should OSB be joined on this line.

Step 5.

Having completed the installation, they attach it on top of the casing windproof membrane. Its sheets are stretched horizontally and fixed with staplers to the OSB. At the joints, the film is overlapped and taped. The material should not be pulled too tight, but there should be no sagging.

Step 6.

Next, the sheathing slats are stuffed for finishing in increments of 50-60 cm. The slats must first be treated with a protective compound and dried. After this, you can begin installing siding, lining or other decorative covering for the house. On a note! If you plan to paint the facade from OSB, then the membrane, accordingly, is installed only on the inside of the house. With this method of cladding, the insulation is placed on the inside of the walls in the cells of the frame and covered with a vapor barrier film. Slabs for interior decoration, for example, plasterboard or the same OSB, are sewn on top of the vapor barrier.

Characteristics of materials for external cladding

Now let’s look at the technical characteristics of popular wall materials. With their help you can choose the most suitable option external wall cladding.

Wood panels

When choosing wooden cladding, you need to pay attention to the following material characteristics:

Humidity – measured in %, it should be no more than 15%. The moisture content of wood determines its warping during use.
The type of wood determines the price and characteristics of water resistance and durability. The most expensive wood options are oak and larch. They are little susceptible to rotting, while oak is very strong and durable. The most popular types of construction wood are pine and spruce, which combine the natural resinousness of the wood with an affordable price. There is also lining and block house made of linden and alder; they are more suitable for cladding interior walls.
The shape or relief of the lining can be flat, convex, concave, wavy. This characteristic is important for the decorative effect of building walls.
The grade of lining is 1, 2 or 3 in the post-Soviet classification or A, B, and C in the European one. The grade determines the quality of the wood - the presence of stains from knots, chips, hidden cracks.
Availability external processing– moisture-resistant, anti-fungal or fire-retardant impregnation.

Vinyl siding

Sheathing a frame house with siding often uses plastic panels made of polyvinyl chloride. This material has proven itself as an affordable wall covering with high decorative properties.

When choosing siding panels, you must consider the following characteristics:

The amount of recyclable materials in plastic determines the quality, durability and price of PVC panels. Cheap panels contain up to 80% recycled plastic and are not suitable for exterior decoration. For external cladding, it is allowed to use panels whose bottom layer contains no more than 5% of raw materials.
The content of modifiers determines the strength of the panel and its price.
Content of other chemical compounds: butadione – no more than 1%, titanium dioxide – no more than 10%, calcium carbonate – no more than 15%.
Panel relief - determines what type of walls vinyl siding will imitate.

How to sheathe a frame house cheaply

Sheathing a frame house with OSB on the outside has gained popularity primarily due to the very affordable price. At the same time, they try to compensate for the shortcomings of OSB, their low moisture resistance and insufficient strength, with additional protection of their surface, plaster or painting.

The choice of panels for cladding an OSB frame house should take into account the category of building material. The category of slabs is indicated by numbers - 1, 2, 3 or 4. It determines the purpose and technical characteristics - strength, moisture resistance, possibility of use in external construction. For plating frame wall slabs of category 3 or 4 are required.

Now let's talk about how to properly sheathe a frame house.

Features of installation of a ventilated facade

The exterior decoration of a frame house is often equipped as a ventilated facade. Especially if cotton insulation was used to insulate the walls - mineral wool or glass wool. This insulating material requires ventilation gap between its surface and the wall cladding. How to sheathe a frame house with OSB, boards or siding?

When building a frame house, a so-called sheathing is constructed under the siding to create a gap between the insulation and the wall sheathing. It consists of wooden or metal strips that are attached to the frame supports. Wall sheathing is mounted on top of the planks. Thus, the outer panels are not located close to the heat insulator, but at some distance from it.

In order to increase the strength of the installation of wall cladding, low-strength sheathing is replaced with wide frame posts. Their thickness should be greater than the thickness of the insulation, then the necessary gap will be formed between the surface of the heat insulator and the outer edge of the frame support after hanging the outer wall panels. This is done to cover the outside of a frame house with OSB.

The presence of a ventilation gap protects the outer panels from moisture. Therefore, such a gap is necessary when building a frame house with imitation timber, “like wood”. Or when using wood chip boards. In the absence of air space, vapor particles will collect in external wall, cause dampness, rotting, fungus.

Exterior finishing of a frame house - is it really necessary?

A modern cottage is wooden structure, built on the principle of a skeleton on which the walls, ceiling, roof and floor are attached. Its universal design gives scope for choice of cladding. Wood itself is not ideal: to prevent heat from escaping through such walls, it is necessary to increase their thickness to 6 centimeters. If metal is used for the base, then the problem of heat loss is even more aggravated. By choosing the right finishing material, you will ensure comfort and health for yourself and your loved ones. The house will be reliably protected from wind, frost, precipitation and high temperatures.

When choosing an option, please pay attention to the following information:

Modern frame houses are lined with materials that can take on part of the load. They give the structure additional rigidity. The main criterion for selection is mechanical strength in compression and bending, and absence of shrinkage.
Exterior finishing must repel moisture, be resistant to temperature changes and the effects of microorganisms - fungus and mold.
The flexibility of the material during processing and ease of installation are important. Especially if you decide to do everything yourself. How easy the installation is depends on total time repair. The selected building material must be amenable to drilling and cutting, while maintaining shear density, and must not crack or crumble.
The material must be durable. This includes saving money, time and effort. You will not have problems with the cladding if it lasts for several decades and does not lose its original appearance.

If a frame house is located in the middle zone, where there is severe frost in winter and heat in summer, it needs to be sheathed on the outside with very high quality.

Brick and facade board - an all-time classic

Natural brick block is a material that is traditional in the field of cladding frame houses. Brick is durable, retains heat well and does not allow cold to pass through, durable.

Given that competent masonry the finish looks attractive, it does not need to be painted or treated with special compounds against moisture, fire or mold. During work, it is necessary to leave a gap between the surface of the building and brickwork. Otherwise, condensation will accumulate inside.

In order to lay a brick beautifully and correctly, skill is required. This finishing option has an average cost.

Another disadvantage is that there is no opportunity to choose an interesting color or texture, as is the case with siding, clinker tiles or artificial stone.

If you love eco-friendly, natural materials and want to save money, choose a facade board that imitates timber. The material has two sides. The planed part is attached to the wall, and the polished part is on the outside. The board is sanded so that the paint is better absorbed into it.

There is already painted material on the market - all you have to do is choose the desired color.

Before decorating your house, read carefully the descriptions of materials that are popular today, take the time to visit a store where big choice for builders. "Live" acquaintance with different options will help you choose what's best for you!

Types of finishing

The exterior decoration of a frame house can be made of various materials, so when choosing a certain type of product, it is worth learning about their features. Some materials can be fixed yourself, while others will have to be installed by professional builders.

In order for the exterior decoration of a frame house to be admired, you need to choose the right finishing materials that are suitable for your chosen design style.

It is impossible to leave a frame house without finishing, so you will have to choose the material in any case.

The most common include:

Hanging structures. Thanks to such products, it is possible to additionally insulate the building from the outside if it is located in a region with a continental climate. When choosing this finishing method, you can use metal, brick, stone and other materials.
Plaster. Such compositions can have different shades, so if desired, you can decorate the house in any style.
Facade brick. When choosing this material, it should be taken into account that the weight of the house increases significantly. That is why it is worth choosing a material for the external design of a building at the design stage.
Siding. This material It is characterized by low cost and a fairly long service life.
PVC panels. Such products can imitate brick, boards and other materials. If the exterior finishing of a frame house is done with my own hands, it is necessary to constantly check the location of each cladding element.
Panels based on polyurethane. This material allows you not only to change the appearance of the building, but also to insulate the facade.
Facade tiles. This material is fixed with glue or using special fasteners for tiles.
Block house. The specified cladding material is created on the basis of wood and gives houses a natural look.

When choosing any material, it is important to purchase only reliable products. The cladding of the house must be done correctly without cracks or gaps. It is best to entrust the work to professional builders. In this case, the finishing of the frame house from the outside will be done with high quality and in a more efficient manner. short time than when creating the cladding with your own hands.

Hanging structures

Wall-mounted finishing structures have many advantages over other types of similar materials. If desired, you can completely change the appearance of the house by attaching the appropriate panels. The frame for securing finishing materials is most often made of metal. In this case, a space is left between the finish and the wall in which the insulation can be placed. Mineral wool is usually used.

It should be noted that the use of hanging structures can improve the sound insulation of the structure, making the house more comfortable. The described structures can be divided into ventilated and non-ventilated. Products of the second type are easier to fasten, which is why many owners choose them country houses. It is also important to consider that the interior decoration of a frame house must be combined with the selected material.

Wet lining

Most often, wet cladding of a wooden house is carried out with additional insulation. Foam boards are used for this. When purchasing, you only need to select slabs for exterior finishing. This type of foam is called façade foam and is marked with the letter f.

Extruded polystyrene foam should only be used to insulate the base of a building. This is due to the fact that such material is more rigid and does not absorb moisture. The foam is glued end to end. In order for the primer to adhere to the surface more reliably, it is necessary to treat the slabs with sandpaper.

After fixing the foam, a special glue is applied to its surface, into which a fiberglass mesh is embedded. After this, the surface is covered with quartz primer. This composition contains sand filler. Only after the described work has been carried out can plaster be applied.

Compositions for finishing Frame house facades are divided into acrylic, silicone, mineral and silicate.

Facade brick

The described material can be divided according to composition and shade. For exterior finishing, the following types of material are most often used:

sand-lime brick;
ceramic;
hyper-pressed.

Sand-lime brick is low cost, while ceramic brick is more beautiful material. Bricks are divided into solid and hollow. Products of the second type retain heat better. That is why many owners of frame buildings choose them.

It is not necessary to install this material in winter time, since at sub-zero temperatures the solution freezes and the masonry becomes more fragile. Before finishing works needs to be calculated accurately required quantity material.

Brick lots may have different shade, which will negatively affect the appearance of the building. To make the color of the masonry more uniform, you can treat the walls with 10% sulfuric acid.

If the exterior finishing is done correctly, the house will look like a structure made entirely of brick. It is also important to choose the shade of the roofing material so that it matches the color of the brick.

Thermal panels with clinker tiles

Many people use thermal panels to cover a frame house. They not only decorate the wall, but also help retain heat in the house. The panels are fixed in a seamless manner. Many owners suburban areas When decorating a frame house, clinker tiles are chosen, since they are not subject to abrasion and deformation by mold.

The material is fixed to the walls as follows:

First, the geometry of the structure is verified. All walls of the house must be perfectly smooth, and the corners are 90 degrees. If there is even a slight deviation, it is necessary to create a sheathing for the entire structure.
Installation of the base profile. At this stage, consolidation occurs aluminum profile in the horizontal direction. During work it is necessary to use a building level.
After this, the corner thermal panels are fixed.
At the next stage, the panels are installed over the entire area of the facade. For this, dowels or screws are used.
Then you need to seal the panels by filling the gaps between the panels. The seams are treated with grout that is resistant to low temperatures.

By selecting this method finishing, you need to be prepared to spend a lot of money, since the material is expensive. You will also have to spend money on the services of builders.

Using tiles to look like brick, stone and other materials

When using tiles, you can not only modify the structure, but also protect it from external factors. Fastening should be done to the lathing in such a way that there is a gap between the finishing material and the wall. It is important to press the tiles tightly against each other, since if there is even a small gap, moisture can get through the tiles onto the wooden walls. The tiles are fixed using glue.

The described material has the following advantages:

Wide variety of shapes and colors. Thanks to this, if you wish, you can decorate your own frame house in an original way.
Easy to install. Even if you hire professional builders, the cost of the work will not be high, since the tiles are fixed quite quickly.
Lightness of tiles. Since the material is light in weight, strengthening the foundation of the house is not required.
Wall protection frame house from moisture and condensation.
Environmental friendliness.
Attractive appearance. Tiles allow you to create a design that is difficult to distinguish from the finishing of expensive types of stone.

If deformations occur, the tiles are easy to replace. To do this, you just need to remove the damaged products, securing new ones in their place.

Using a block house

If you want to design the building as a house made of timber, you should use a block house. This material is a part of a rounded log with a flat surface. It is this side that the material is fixed to the wall, due to which, after finishing work, it seems that the house is built of logs.

In addition, the block house has other advantages:

Protection from environmental influences. The material is coated with special compounds that extend the life of the wood.
Possibility of insulation and fastening soundproofing material. Mineral wool is often placed under the finishing.
Fastening the described products can be done with your own hands. It is not necessary to hire professional builders to carry out the work. But it should be remembered that to avoid errors it is important to carry out work with an assistant.
Possibility of replacing each finishing element of a frame house.

Structure and features of frames

Do-it-yourself interior finishing of a frame house, as well as external finishing, should be done taking into account the structural features of this type of structure.

The following differences most noticeably affect the finish:

The load-bearing basis of the house is a wooden frame, which distributes the load through a system of posts, beams, rafters and crossbars from the roof of the structure to its foundation. As you know, wood is a fairly flexible and soft material, and under the influence of forces the frame gives some shrinkage, uneven displacement and movement of parts relative to each other is observed;
As a rule, frames are placed on columnar or pile foundations, and uneven subsidence of the structure is possible, which is not particularly fatal for the frame, since it is flexible and can allow slight distortions and changes in geometry, but a monolithic coating, such as plaster, can crack;
The walls of the house consist of a system frame beams and panels that fill the space between the beams. Often, instead of panels, this space is filled with insulation and sheathed on both sides with moisture resistant OSB plywood, which by itself cannot perform the functions of façade finishing either in terms of decorative or structural characteristics;
The structure of the wall is such that the insulation is located in its internal space, therefore for the middle zone and south external insulation not required. At the same time, many still sheathe their houses with polystyrene foam, since it is an excellent base for plaster.

All these features allow you to determine how to decorate the outside of a frame house so that the coating lasts as long and efficiently as possible. As a rule, preference is given to hanging facade structures, various panels and slabs, wood paneling and plaster.

Important! Facade decoration facing bricks are produced very rarely, since a frame house is an option for budget prefabricated housing, and the price of laying work and the cost of the brick itself make this advantage insignificant.

Preparing the sheathing surface for painting

In order for the paint to adhere well to the surface of the sheathing boards, it is necessary to process the entire surface using a sanding machine, while the sanding machine must be filled with sandpaper (gradation of sandpaper grain for sanders 25, 40, 80,120) I used with grain 40.
If we plan to paint the facade of the house with oil paint, then first apply two layers of drying oil to the surface of the cladding, after it has dried, we proceed to painting the house.
The sheathing surface can be painted with a wide brush, roller or using a spray gun.

Finishing window openings

Plastic corner for the decorative appearance of the ends of the siding panels in the window opening

In order to hide the ends of the siding panels at the window openings, I used a plastic corner instead of wooden trim.
I secured one side of the corner to the front side of the panels, and the other side hid the ends of these panels. The corner was installed in such a way that one end fits snugly against the window opening.

Note: siding panels can be trimmed using a metal file, or using an electric jigsaw with a fine-toothed file.

Important! Sheathing the walls of a house with siding should be done in the warm season. Since at temperatures from + 15 degrees, siding panels have better ductility than at low temperatures.

Also, do not pull the panel up too much when installing it, since when sub-zero temperatures, the siding will shrink and if it is tightly stretched at the time of installation, the panel may simply crack.

Installation and insulation of sheathing

All materials used for cladding a frame house, with the exception of boards, are sheet materials. Therefore, installation usually does not pose any particular difficulties. To fasten the sheets to the base of the frame, nails with a wide head of a suitable size are used. However, the length of the nails must be at least 70-80 mm.

Since some of the materials are more fragile, they can be fastened using screws - when screwed in, they do not leave cracks and do not split the slab.

The slabs can be installed depending on the size of the wall and the size of the perimeter. Their location can be vertical or horizontal - this allows, depending on the situation, to more economically use the remaining material after trimming.

To enhance the insulating qualities of the sheathing material and give an even greater degree of heat capacity to the structure itself, it is necessary to lay thermal insulation materials. The building materials market currently produces enough products with such qualities.

Thermal insulation materials can be roll type or in the form of small slabs.

For this purpose, the following can be mounted under the casing:

Foam sheets. Depending on the sheathing material, the thickness of this insulation should be from 50 mm and above
Expanded polystyrene– the material is even more efficient than the previous version due to its high density. However, its cost is much higher. In cladding work, polystyrene foam thickness from 30 mm is used
Mineral wool– roll type of materials. Has excellent insulating properties. But due to the characteristics of rolled products, this material is characterized by higher labor intensity during installation.

Along with these classical materials, their modern analogues can be used. In most cases, the procedure is completed by laying insulating materials and installing sheathing materials.

However, in some cases, additional treatment of the outer surface of the cladding is carried out with soil mixtures to give them greater technological characteristics, withstand the external environment and strengthen the outer layer of the slabs.

Oriented Strand Board or OSB - the new kind material used primarily in the construction of private houses. The scope of application of particle boards is wide - from construction - to external wall finishing, installation of floors and internal partitions- to the production of furniture, design of containers and finishing of transport bodies. Slabs of this type allow you to fill large surfaces with an even, solid base, while saving a lot of time and financial resources. But having covered the walls practical material, the question of surface finishing arises: how to paint OSB on the outside?

What should you consider when finishing OSB?

External finishing of OSB is complicated by the influence of external conditions, including weather: it is necessary to take into account temperature fluctuations, exposure to moisture and ultraviolet radiation. OSB board consists of 90% wood, so its high-quality finishing requires materials suitable for processing solid wooden surfaces. One or both sides of such a slab can be either smooth or rough. Brown OSB is usually smooth, and the boards golden hue- most often moisture-resistant, treated with resins, so they will not absorb moisture-containing processing agents.

Exterior OSB finishing

The slab needs to be finished different ways: gluing, painting, puttying, varnishing and plastering, subject to certain conditions. Traditional finishing options are clinker tiles, lining, siding. If it is important to save materials, then The best decision- This OSB painting. Any wood dye will do; you just need to take care to seal the gaps at the ends of the slabs (acrylic sealant).

Finishing options for OSB boards:

1. Paint

A good option is water-based paint with its excellent ability to allow moisture to pass through and promote a healthy indoor microclimate. When using water-based dyes, you must first apply them to a test area and evaluate the painting result, taking into account the characteristics of the material. You can process it particle board Biotex in two layers with a roller or coated with enamel paint, pre-treated with wood putty. If you choose acrylic water-based dyes, as an option, Nordica Eco 3330-03 paint will look good. Of the primers, the most preferable primer is GF-020 or GF-021.

2. Varnish

When painting with varnish, the surface must be thoroughly cleaned and degreased. If the slab is not sanded, this should be done manually using sandpaper and then primed. The varnish lays flat on the surface, giving it perfect smoothness. If saving the drawing does not have important, then the external surfaces can be painted with acrylic varnish.

3. Tiles

To lay the tiles, you need to provide an adhesive, the ingredients in which interact with wood and ceramics.

4. Linoleum, carpet

If you think that better finishing solid materials * than painting OSB on the outside * with paints of any kind, you can try using roll coverings. Covering wood slabs linoleum or carpet, you need to eliminate irregularities at the points of contact of the slabs with the coating, and process the gaps silicone sealant. For such work, the thinnest slabs are preferable.

5. Laminate

To lay laminate flooring, you need to ensure a flat surface. If the slabs are laid correctly, in addition to the laminate, the result is a perfectly smooth wall.

6. Wallpaper

An interior finishing option that requires a preliminary primer and adds PVA to the wallpaper glue. The traditional method of gluing wallpaper is not suitable here: the glue contains a large amount of moisture, so if it is absorbed into the surface, the slab may swell, causing the wallpaper to fall off.

If decoration is required inner surface, you need to take into account the properties of the glue: thermoplastic glue is designed to work and fix in dry conditions; thermal hardens at room or elevated temperature; urea-formaldehyde has limited water-repellent properties, so it may not be suitable for areas not protected by an awning; elastomer adhesive - good for fixing thick-layer parts; Bitumen-based adhesives are commonly used in roof construction.

OSB or OSB board is an oriented strand board. Due to its strength, which is much higher than that of chipboard, this material is very popular in construction. Do-it-yourself cladding of a house with OSB slabs on the outside is relatively simple and a budget option.

Scope of OSB and types of boards

In classic chipboard, sawdust is mixed together with the variety epoxy resin As a result, in the finished frozen formation they are located chaotically. In an OSB board, they are oriented by vibration not only along the layers, but also in the direction of laying, as a result of which the board receives much greater fracture strength. In fact, OSB is one of the options for composite materials.

OSB boards differ in the degree of their resistance to high humidity, as well as in strength characteristics: how well they can withstand fracture loads. There are 4 grades of OSB: from OSB-1 to OSB-4. Each of these types uses its own types of adhesives, which impart the corresponding properties to the finished slab.

OSB is used for both interior and exterior decoration. Nessesary to use different types slabs according to their resistance to moisture. OSB boards are durable and practical; they allow the formation of complex facades for subsequent painting or plastering on the outside or wallpapering on the inside.

How to properly attach OSB to the wall

Most often, OSB is used in the construction of frame structures, where slabs are used as a structural material.

To create the outer wall plane, you should use boards of no lower quality than OSB-3. Only such material is sufficiently stable for the humidity of “outside” air at any time of the year.

When designing such a building, the following features should be taken into account:

the frame posts should be located exactly 2 times more often than maximum length slabs intended for use. Then the panel will be quite rigid;

when forming the outer wall plane, you first need to attach a windproof membrane to the frame posts, the role of which is suitable for PVC film;

In frame-panel houses there is a layer of insulation throughout the entire depth of the wall (which is the thickness of the wooden studs). To prevent it from becoming damp due to internal humidity, before installing the internal wall surface, a vapor barrier membrane (also polyethylene film) should be attached to the frame posts;

After this, OSB can be attached to the frame posts.

The slabs should be fastened with self-tapping screws or nails. It is important that their length is at least 2 times the thickness of the OSB used (they are usually produced from 9 to 12 mm thick). Of course, for the outer surface you need to choose thicker slabs than for the inner one.

Sheathing a house with OSB boards on the outside

OSB boards are widely used for constructing lightweight ventilated facades of brick or concrete houses. IN in this case the algorithm is like this:

Initially, markings are made on the wall surface where the U-shaped holders will be attached. They are fastened with screws on dowels;

then a layer of insulation is laid on the surface of the wall with glue. It is most effective to use mineral wool. In this case, you initially need to calculate the required length of the U-shaped fasteners so that their holders remain 4-5 cm above the surface of the insulation layer. The ends of the holders must pierce the insulation layer;

Next, we insulate the surface of the insulation with a moisture-proof membrane, for example, polyethylene film. This is necessary so that the insulation does not become damp, picking up moisture from the surrounding air;

then wooden guide bars are attached to the holders. This is a sheathing for OSB panels. It turns out that a gap equal to the thickness of the guide is formed between the membrane and the OSB boards. It is necessary to ensure ventilation of the internal space. The guides must be made of completely dried wood so that there is no geometric warping in the future.

then OSB boards are attached to the guides using nails or self-tapping screws.

Decorative finishing options

For interior walls, OSB boards are ideally smooth, sufficiently durable and absolutely dry surfaces, ready for further puttying, painting, and wallpapering. Also after plastering you can apply relief plaster. Then the interior space will look original. This will require less effort.

For the outer surface of the walls, such panels also need to be plastered, and then they can be:

paint;

lay out with decorative facade panels;

trim with clapboard or siding.

Painting a house with OSB boards

Dyeing is the most inexpensive and practical way final finishing of walls formed from OSB. There are two options here:

painting without prior priming. In this case it is better to use acrylic paints or polyurethane varnishes. But you need to remember that the surface texture will definitely show through the pigment layer. If this is unacceptable, then additional processing is needed.

By priming we mean plastering the surface. OSB is a completely dry material that adheres well to adhesive putty. Then comes the painting stage, after which the house will look elegant and attractive.

Covering OSB boards with siding

One of the options design solutions– covering the wall with OSB siding. But there is one subtlety here: the siding panels do not adhere closely to the OSB surface. They specially have a figured relief in cross-section so that the resulting space is ventilated.

Therefore, first you need to take care of OSB waterproofing. Best choice here the OSB boards will be treated on the outside with dispersed impregnation, giving any surface water-repellent properties. It is possible to place a polyethylene film on top of the OSB board, which will protect the panels from moisture.

Many builders sheathe the outside of the house with OSB (OSB) boards. This material is affordable and differs high quality. When the time comes for final works, craftsmen are thinking about how to paint an OSB board on? For the right choice you need to study all possible options used for this product.

What is OSB board?

The first OSB boards have already been created more than thirty years ago during mass developments from frame materials. Most residents of Canada, the USA and many Europeans live in such houses.

For the first houses made using frame technology, it was required reliable casing, resistant to sunlight and moisture. Wood was not suitable for this type of installation, as its installation took too much time and effort.

Plastering

This option for covering OSB panels is the most popular and justified for outdoor work. This type of finish has a number of features:

Siding

The use of sheathing with the installation of siding panels is an economical method that helps improve the appearance of the building.

Siding can be fixed to the installed OSB surface.

There are a large number of options for siding panels, so if you wish, you can choose a model that imitates a block house or brickwork.

The advantage of such cladding is that if OSB boards are already glued to the side of the facade, it is not necessary to mount an even frame. However, you can't do without a membrane which will protect from wind and moisture.

If this additional fastening is not installed, the siding will periodically sweat from the inside, and the OSB will swell under the influence of moisture.

If you choose between two types - PVC or acrylic, then you can choose any type, since there are no significant differences between them.

Facing products are produced in one thickness, varying from 0.8 to 1.3 millimeters. They are able to withstand temperatures reaching 80 degrees Celsius, and exposure to sunlight, under which they do not fade.

Both types are highly resistant to the spread of fire and chemical reagents. Acrylic panels have a rich color, but otherwise are almost no different from PVC products.

How to plaster a slab outside the house?

The question of whether it is possible to putty the surface of OSB boards is controversial: some experts believe that this coating will not protect the product from the appearance of cracks on the surface of the facade. Others, on the contrary, recommend using an additional coating, because it will refresh gloomy wooden panels and serve as protection against moisture and dust.

Carrying out high-quality work on plastering the facade of the building can be done subject to the following conditions:

the surface must be coated with an adhesive compound before carrying out work;
the solution applied to the surface with a spatula should not be thinner than three millimeters;
use of reinforcing mesh after applying the first layer;
surface coating adhesive composition after the first layer has dried.

The surface of OSB slabs visually looks decent, and some home owners leave them at this stage and do not additional work on the cladding of the building.

Many experts still recommend covering the slabs with plaster - this will not only give the house individual features, but also protects against external damage. In order to perform plastering efficiently, you need to follow the sequence of work:

When applying the first layer, you should try to run a wide spatula along the wall to fill all the recesses on the OSB. For correct application you need to move the tool along the wall in arcuate movements. Completion of the first layer should not be accompanied by streaks along the surface to be coated.
After the first layer has completely dried, clean the wall with an abrasive mesh and repeat the application of putty.
In order to achieve an ideal surface with a smooth shine, you need to apply at least five successive layers.
After applying the putty, the surface must be dried, after which a layer of paint can be applied to it.

Even experienced craftsmen ask the question of what is the best way to carry out the work of filling panels. The work process can be complicated by the fact that most putty materials do not adhere well to wood surfaces.

Therefore, you need to choose those coating models that have the highest adhesion to a wooden surface.

In order for the work to be completed successfully, it is recommended to pay attention on a mixture of Rodband and Goldband. These mixtures are made on a gypsum basis with admixtures of polymer materials.

If the owner of the premises wants to save on putty material, then it is better to purchase Rodband, its texture is more rigid than that of Goldband, and the price is much lower.

The selection of finishing is also important, and should be approached carefully. In order not to make a mistake with this choice, it is recommended to purchase Vitonit KR mixture.

Installation of porcelain tiles

Porcelain tiles are suitable for gluing to OSB walls, but is it necessary to carry out such serious work that can also cause damage to building structures?

Porcelain stoneware tiles are resistant to fungal growth, moisture and mold. One of the most important advantages This material is considered to be sustainable and has a wide range of products in stores. All these advantages are suitable for carrying out interior work, but not external ones.

OSB panels can be tiled indoors, for example on the floor, but external work is not recommended.

Craftsmen do not use porcelain stoneware in facade work one at a time main reason – the wall surface must be ventilated in order to avoid waterlogging and swelling of the panels.

OSB coloring agents

In addition to water-repellent protection, paint coating provides a number of advantages for the surface:

the coating can protect wooden surfaces from premature deformation;
if large chips are noticeable on the surface of the wall, they can easily be hidden after applying the impregnating solution;
Compared to other materials, painting is quite cheap and is not inferior in protective qualities.

Typically, for outdoor finishing, OSB-3 or OSB-4 is used, which are the most resistant to weather conditions. Not every owner can purchase OSB-4, since this material is highly expensive and resistant to mechanical stress. If the “four” is completely protected, then OSB-3 requires additional coating.

The boards are made from wood, which is the main component of the product, giving it environmental properties. At the same time, such a natural composition makes the wood product vulnerable to the onslaught of weather conditions.

Give additional protection You can use siding, artificial stone, or the most common and easy-to-install material – paint.

When choosing a composition suitable for outdoor use, you can pay attention to all mixtures intended for working with wooden surfaces.

It is necessary to avoid coatings that spoil the appearance of the facade. These include glazing substances and gloss varnishes. These compounds will show off and highlight the texture of the chips, which is not particularly attractive. Therefore, it is better to refuse such products.

The following compositions are suitable for coating OSB boards:

Latex compounds.

Latex paint contains substances that are most suitable for working with wood material. After application, the paint is not subject to stretching and does not leave smudges. The disadvantage of this option is high cost of material.

Alkyd paint.

Often used in such work. Its peculiarity is that it looks attractive after being applied to the wall. This composition takes a long time to dry, sometimes up to eleven hours. The composition evaporates before it dries completely. bad smell. After drying the composition, the smell disappears.

Paint is capable withstand elevated temperatures, but is not resistant to fire and alkalis that get on the surface of the product.

Acrylic mixtures.

It is also often used, but if you read the composition of this paint, it will become obvious that it is not an ideal option for OSB coating because it contains water. Water-based paints in contact with OSB panels capable of spoiling their composition.

But if the panel is strong enough, then you can use acrylic composition, which has undeniable advantages: resistance to sunlight, smooth coating and the ability to stay on the facade for more than eight years.

But it is important to remember that if you leave jars of paint at a low temperature, the composition will deteriorate, because water turns into ice. The composition without water will be unsuitable for further use.

Oil mixtures.

Previously they were widely used, but today they are almost out of use. This happened due to the displacement of this mixture by other more popular ones.

Oil suspensions toxic in composition, and the work has to be carried out in special masks or a respirator. The oil takes too long to dry and spreads over the painted surface, which of course requires additional effort to restore the wall and eliminate smudges.

After work on applying the suspension, rags often form that spoil the appearance of the facade. Another unpleasant property of this paint is the impossibility of covering it with a new composition that differs in components.

In order for the painting job to be completed safely and without additional effort and touch-ups, you need to remember a number of features of the wooden material:

If there are sharp protrusions on the building, they will contribute to the spreading of the paint composition. If there are such corners, they need to be rounded, as in a plasterboard;
the edges and joints of the slabs must be puttied to eliminate possible difficulties in applying and smoothing the wall;
The question of whether it is necessary to prime the surface between the wood and the paint should not arise, because there is a clear answer to it - yes. This action is mandatory for precise adhesion between the paint and the material;
if the owner wants to achieve an even application of the composition over the entire surface of the wall, he will need to apply finishing putty to all the slabs;

The number of times for applying paint is determined individually, but experts advise painting at least four times. After the paint has been thoroughly absorbed into wooden surface the color of the product will become saturated, and the strength of the composition will noticeably increase.

It is important to remember that each layer has its own time to dry, and you cannot start painting before the previous mixture has dried.
