Exterior decoration of houses made of foam blocks. Houses made of foam blocks: exterior finishing

Despite the fact that houses made of foam concrete have high heat and sound insulation characteristics, and are also a relatively inexpensive material, they have a number of disadvantages.

Foam blocks are an artificial material based on concrete; it has a foamed structure, which ensures its properties. The use of special compounds will allow air to be evenly distributed throughout the structure of the material, so the foam concrete is porous

Positive qualities of foam concrete:

light weight;
sufficient strength;
does not burn;
It has long term services;
high heat and sound insulation characteristics;
smooth surface, which facilitates finishing work.

Flaws:

foam concrete has low moisture resistance, water penetrates into its structure, and this causes chemical reaction, in which the material gradually deteriorates. To avoid this, the interior decoration of the house must be made of foam blocks and high-quality vapor barrier of all walls must be done;
In addition, this material is porous, so its density is low, this must be taken into account when fastening the interior trim.
When plastering, it is imperative to use reinforcement.

Finishing walls with plasterboard

There are many ways to decorate the walls of a house made of foam blocks that you can do yourself. One option is to use drywall; it can be attached either with or without a frame.

Fig.1 Frame installation

If the walls are laid correctly, frameless technology can be used.

In this case, the walls are cleaned of any remaining mortar; if necessary, the sheets of drywall are leveled and glued. It takes 20-30 minutes for the glue to completely harden.

If the walls are uneven, then you can install a frame, it can be made of metal profile or from wooden beams and drywall is already attached to it. The frame pitch is usually 60 cm.

Although this method takes away part of the room’s space, you can hide communications and put insulation in it, which is very convenient and effective. After installing the drywall, the joints are sealed, and then you can paint it, glue wallpaper, plaster or lay tiles.

Working with lining

A fairly popular way to decorate the inside of a house built from foam blocks is to use lining.

Lining is boards of small thickness, which are fastened together using special locks, after which a solid covering is obtained. It can be made from various materials, For example natural wood, plastic, waste from the woodworking industry.

Popularity of this material due to its low cost, installation is simple, everything can be done with your own hands.

It can be mounted on walls both vertically and horizontally, the sequence of work does not change.

To attach the lining it is necessary to make a frame, for which it is used wooden beams or metal profile. If wooden beams are used, they must be impregnated with an antiseptic and fire retardant in order to protect them from rotting and improve their fire-fighting characteristics.

Particular attention should be paid to the installation of the first board, since all subsequent ones will be attached to it. In order to check the correct installation of the first board, use a building level or level.

To fasten the boards to the frame, clamps are used, which makes the fastener durable and invisible.

Other options

For a house made of foam concrete, the interior decoration can be made from other materials. The main condition is to perform high-quality vapor barrier of the walls. Best to do external thermal insulation, but if this is not possible, then it can be done from the inside.

This material can be produced both in rolls and in sheets. Since cork is a finishing coating, before installing it, it is necessary to properly prepare the walls; they must be clean and smooth.

Fig.2 Using a plug

Before installing the plug, the walls must be plastered and coated with primer deep penetration and let it dry well. Before gluing it, the cork needs to stay in the room for about a day. Installation is carried out using special glue. Read about their use, installation and cost.

Use of penofol

This is a modern material that is foamed polyethylene, covered with aluminum foil on both sides.

Fig.3 Laying penofol

A frame is made on the wall and penofol is attached to it. All seams are taped with special aluminum tape, which ensures the integrity of the coating. After this, the final covering, such as clapboard or drywall, can be laid.

For such a house, you need to take breathable gypsum-based compounds. In order for the plaster to lie securely on the wall, it is necessary to use a reinforcing mesh. After plastering the walls, you can paint them or wallpaper them; they must be moisture-permeable.

Fig.4 Plastering walls

If you apply plaster in a layer of 10 mm, then a bag weighing 30 kg will be enough for approximately 3 square meters of wall. Before starting work, the frost needs to be moistened.

A mixture of water and cement can be applied as the first layer, after which plaster is immediately applied. The work is carried out in small areas. If further painting or wallpapering is planned, then the surface is additionally rubbed down using a trowel.

To create a pattern, before painting, you can apply patterns on a not completely dry wall; this is done using a hard brush, relief roller or comb spatula.

MDF panels

This material not only has an attractive appearance and is easy to install, but also has high heat and sound insulation characteristics, therefore it is often used for finishing inside the house.

It does not fade, has a long service life, and if it is damaged, it is enough to simply replace one or more panels.

To perform high-quality interior decoration, you need to lay the walls correctly. Many craftsmen make the mistake of laying foam blocks using regular mortar. Its installation must be done with a special glue, due to which the seams are minimal in thickness and the walls are even.

Another mistake that is often made when building such a house is the lack of reinforcing belts. They should be done on all walls, every 4-5 rows, and not just in the window sill area.

This allows you to make a durable building, and when it shrinks, the walls and, accordingly, the interior decoration of the house will not be destroyed.

First you need to do the internal ones Finishing work, and then move on to finishing the facade. It is better to carry out the work in the summer, so that the moisture that gets into the foam concrete dries out and does not freeze.

For priming, it is necessary to use special compounds for foam concrete; they penetrate into it by 2-5 mm and reliably protect against moisture getting into the material.

Table 1. Cost of materials.

Most of the work on the interior decoration of a house made of foam blocks can be done with your own hands and thus save money.

If you decide to invite specialists for this, the cost of their work will depend on the material you choose for finishing, on average it is 40-60% of the cost of the material itself.

Specialization: Capital construction works(laying a foundation, erecting walls, constructing a roof, etc.). Internal construction work (laying internal communications, rough and fine finishing). Hobbies: mobile communications, high technology, computer equipment, programming.

One of the most critical stages of building a home made of cellular wall materials– external and internal decoration of the house from foam blocks. It should not only decorate, but also protect the walls from destructive factors, but at the same time not impede air infiltration.

Today we will talk about the best way to decorate the facade of a house made of foam blocks, and how to arrange the walls inside.

Features of walls made of foam blocks and finishing for them

Foam block, as the name suggests, belongs to the category of porous building materials. In its production, a gas-forming substance is used, due to which more bubbles appear inside the solidifying mixture.

Thanks to this, the walls have high degree vapor permeability. Natural air infiltration passing through the enclosing structures helps to establish a microclimate comfortable for living inside the home.

This applies to both humidity levels and temperature. After all, foam concrete has a low thermal conductivity coefficient, that is, in some cases, walls made of it do not require insulation.

However, there is also a downside to the issue. Foam blocks themselves do not have high mechanical strength and can be damaged as a result of mechanical stress. In addition, they absorb water well, which freezes when negative temperature and destroys blocks.

Therefore, dwellings made of foam blocks must be finished inside and out. But the material used for this must have certain properties, which are described in detail in the table below.

Characteristic	Description
Vapor permeability	Decorative finishing should not impede air infiltration through cellular enclosing surfaces. This helps regulate the microclimate in the room and remove moisture from load-bearing walls.
Frost resistance	Exterior finishes must withstand multiple freeze and thaw cycles without damaging the internal structure or changing the appearance. This also applies to interior decoration, if the home is in winter time heating is not intended.
Waterproof	The finishing material, both internal and external, must reliably protect the foam blocks from moisture. Outside it can be affected by rain or snow, inside - water vapor and jets of water (for example, if the interior decoration of a bathhouse is being carried out).
Strength	The selected finish must withstand significant mechanical stress, including impact.

I will not talk about decorative properties, strength, ultraviolet resistance, and so on, since these characteristics should be inherent in all finishing materials, especially facade ones.

However, I would like to note, especially for novice craftsmen, that the outside of a foam block house, in addition to the compartment, should also be equipped with:

rain and melt water removal system;
visors;
drains under window openings;
protection system ground floor and the foundation from moisture penetration;
a properly constructed roof.

Now I’ll tell you about the specific materials used to make the internal and exterior decoration foam block.

Exterior materials

First, let's figure out how to decorate the facade of a house made of foam blocks. I made a small diagram showing all the possible options.

Let's look at each method in more detail.

External cladding materials

One of the frequently used methods of finishing a foam block home is cladding the surfaces with ceramic (clinker) bricks, natural stone or facade tiles.

I'll start in order:

Brick. One of the most common materials.

The brick is laid at a distance of 5 cm from the main foam concrete wall to form ventilation gap. To decorative masonry was level, experts advise using a technological sheet, which at the same time prevents the mounting solution from getting into the gap between the main and decorative walls. As it moves up, the sheet rises along the masonry.

Under the eaves in rows brickwork must be left ventilation holes. Their total area should be approximately 2% of the wall area. If the house is not intended to be used during the cold season, ventilation may not be necessary. But be prepared for increased humidity levels inside living rooms.

External decorative brick cladding must be connected to the main walls. I recommend making at least four connections per square meter of surface. For this you can use:

stainless steel bandage tape 19.1 mm wide and 1.1 mm thick;
nails for cellular concrete;
galvanized perforated strip;
flexible connections made of basalt plastic.

To make it more convenient for you to choose, I will provide a table that describes in detail the pros and cons of this type of finish:

Advantages	Flaws
Facing bricks reliably protect foam block walls from precipitation.	In some cases, whitish spots (efflorescence) may appear on the finish, which worsen the appearance of the building.
External finishing gives additional strength and stability to the constructed building.	Brick finishing is quite expensive. You can choose and use budget options.
Finish from clinker bricks can be operated under strong temperature fluctuations. At the same time, it does not lose its original appearance and strength.
The material significantly increases the service life of the building’s load-bearing walls.
During operation, the described finish does not require additional maintenance, constant touch-up or plastering.

A natural stone.

The weight of the finish will be very large, so to install it you need to have a very reliable and fairly wide foundation. It is necessary to take care of its design even before the construction of the house begins.

As in the previous case, I will briefly summarize the advantages and disadvantages of this type of facade finishing:

pros	Minuses
Attractive appearance. There are a huge number of finishes on the market - from wild stone to polished tiles made from it. Home decoration options are limited only by your imagination.	Partial destruction of the facade. Due to poor installation a natural stone may peel off from the foam concrete. However, there is nothing to worry about, since spot repairs are not difficult even for a non-professional.
Practicality. The stone reliably resists destructive external influences: water, sun, frost, etc. This type of finishing of a foam block house will last as long as possible.	Possible radioactivity. Some types of minerals emit radiation, but the dose of radiation received is very small and is completely within established limits.

Tile. Decorating the outside of a house with foam blocks does not require a foundation, since the cladding is glued to the walls and does not rest on the base. At the same time, it reliably protects the porous material from external influences, and its appearance can imitate many materials, including natural stone or ceramic brick.

For the exterior decoration of foam block facades, you can use the following types of tiles:

Facade ceramic.

For external work it is necessary to use frost-resistant tiles.

Porcelain tiles.

Clinker tiles.

To make it easier for you to make a choice, I have compiled a small table where I described the pros and cons of tiles from the point of view of their use as facade finishing:

Advantages	Flaws
The tiles do not allow moisture to pass through to the foam blocks. There are no microcracks in it, which are inherent, for example, in natural stone.	The main disadvantage of the tile is its low vapor permeability. The finishing almost completely stops air infiltration.
The facing tiles retain their specifications regardless of the ambient temperature. She endures high temperature in summer and low in winter.	The cost of the finishing described cannot be considered budget, but it is not the most expensive either. However, here you also need to take into account the costs of preparing the surface, purchasing glue and other nuances.
The tiles withstand external mechanical stress well.	The total weight of the tiles can be quite large, which must be taken into account when calculating the strength characteristics of the foundation of the house.
Using different colors and textures, it is very easy to give a boring foam block structure a unique look.

Plaster

For cellular material it is necessary to use plaster, which does not give atmospheric moisture be absorbed into the enclosing structures. The top should be painted vapor-permeable. facade paint or cover with decorative facade plaster(for example, “bark beetle” or the like).

This option should be recognized as one of the inexpensive and easy to implement, but not very durable. In addition, you still need to have some skills in leveling surfaces using plaster mortar.

The surface must be properly prepared before plastering. Typically, foam blocks are cleaned of dirt, dust-free, and primed. Only after this are two layers of plaster applied - starting and finishing. Naturally, compositions that form a vapor-permeable layer should be used.

Fiberglass mesh is used to strengthen the plaster. It reinforces the solution, preventing it from crumbling and collapsing during operation.

Personally, I advise resorting to plastering in cases where you are going to simultaneously insulate the house using foam plastic or mineral mats. Then the plaster simultaneously serves as a protective layer and decorative finish for.

To make it easier for you to form your own opinion about plaster, I have compiled a table where I described its pros and cons.

Advantages	Flaws
The finish has hydrophobic properties. This allows foam concrete blocks to maintain their integrity for a long time.	To apply plaster on walls you need to have certain skills and have the appropriate tools.
Hardened plaster has good strength and protects blocks from damage as a result of external mechanical influence.	The service life of the plaster is up to next repair or restoration does not exceed 10 years.
The material does not prevent air diffusion through foam blocks. The water vapor accumulated inside is released outside.	The material is sensitive to vibration and can crumble when the base vibrates.
By using decorative plaster you can effectively decorate the facade of a building using materials different colors and textures. The possibility of tinting the composition or painting it with paint further diversifies the exterior.	Preparation of the composition and its application requires strict adherence to the proposed technology.
The cost of material and application of plaster is quite affordable for all our compatriots.

Ventilated facade

If you built a house from foam blocks, then I advise you to use this particular finishing method. In this case, between decorative material and main load-bearing wall a ventilation gap remains, thanks to which the vapor permeability of surfaces is not impaired, which has a positive effect on the life of the house and the microclimate in it.

The following materials can be used to make a ventilated façade:

Mounted cassettes. A finished aluminum structure, which can often be seen on multi-storey city buildings, commercial and industrial premises.

Buying a mounted cassette facade system The kit includes everything you need for its installation, and the installation process itself is described in detail in the instructions and usually does not cause any difficulties.

However, it should be said that the price of such a solution will be quite high.

Profiled sheeting. It is a metal sheet of a certain shape (with ridges and recesses), which is installed on a pre-designed sheathing.

Metal profiled sheets are protected from the destructive effects of the environment by an outer decorative layer, which usually comes in two types:

zinc coating – a budget option corrugated sheeting, which does not have outstanding decorative properties, but is able to reliably protect foam blocks from mechanical influences and hydration;
polymer coating - highly resistant to external influences and attractive appearance, can have different colour and texture, which makes it possible to diversify the exterior of the building.

I recommend using the last option of the two listed. Well, of course, I bring to your attention a table that makes it easier to make a decision on your choice.

Advantages	Flaws
Ease and simplicity of installation of the profile. To install the cladding, you need a simple frame that is attached to the walls made of foam bloat.	The high level of noise produced by the corrugated sheet during rain.
Resistance to external weathering, corrosion and biocorrosion. The material does not require additional finishing (for example, painting or antiseptic treatment), which is usually used when facing a block house or lining.
Durability and ease of maintenance of the façade finished with this material. The profiled sheet does not require any additional maintenance during its entire service life. If the protective and decorative layer is severely damaged, it is better to completely replace the part.
Fire resistance. The material is not flammable and does not contribute to the spread of flame.
Wide range of colors. Polymer coating profiled sheets can have different colors.
The corrugated sheet is completely sealed and does not allow moisture to penetrate to the load-bearing (enclosing) walls made of foam blocks.

Vinyl siding. Another popular finishing option, which can easily be classified as quite budget-friendly. We are talking about panels made of plastic. Thanks to special additives, the polymer acquires various colors and shades, increased strength and excellent performance properties.

To make it easier for you to make your choice, I will list the main advantages and disadvantages of vinyl siding:

Advantages	Flaws
Vinyl siding does not absorb moisture during rain and melting snow.	Poor-quality finishing material can crack due to strong temperature changes.
Features a wide variety of colors that do not fade under direct sun rays throughout the entire service life.	If the installation order is not followed, vinyl sheets may be destroyed by strong winds.
The material perfectly withstands exposure to low air temperatures and many successive cycles of freezing and thawing.
Vinyl siding does not rust over time and is not susceptible to biocorrosion, regardless of operating conditions.
Installation finishing material You can do it yourself by attaching sheets of siding to a pre-designed frame.

Fiber cement boards. Another modern look external finishing of foam concrete walls, which provides ventilation of the enclosing surfaces, and their protection from rain and melt water, and insulation.

In addition, the appearance of fiber cement panels makes it possible to decorate the facades of the cottage in a stylish and original way.

Materials for interior finishing

Now let's turn to the materials used to finish the foam block from the inside. There are many options, but the most common include the following:

Plaster. When working on foam blocks, I recommend using compounds that have high vapor permeability and good hydrophobic properties. It is allowed to use dry construction mixtures based on cement or gypsum.

To make the plaster durable, I advise you to use reinforcing fiberglass mesh for interior work (with small cells). Experts advise plastering the walls so that the thickness of the layer inside is twice as thick as the outside plaster.

One package of dry plastering mixture weighing 30 kg is used to cover three square meters walls with a layer 1 cm thick. Based on this, you can calculate the cost of purchasing building materials. I’ll say right away that if you laid out the walls correctly and used adhesive for foam concrete, then the surfaces will already be quite smooth and there will be no need to apply a thick layer of plaster.

The top of the plastered surface can be painted with interior paint or covered with wallpaper. In both cases it is necessary to use over the starting one finishing plaster, which should be very carefully smoothed with graters and then polished. Otherwise, flaws may appear on the surface.

Drywall. In my practical work, I very often finished foam concrete walls with plasterboard. This universal material, with which you can easily level surfaces of any curvature and build very complex multi-level architectural elements.

To attach drywall to foam blocks, you can use glue or a frame made of galvanized profiles. I resort to the second option, since in this way it is possible to insulate the walls and lay them behind a false wall engineering Communication without resorting to gating.

In addition, when using a frame between decorative finishing and the enclosing wall creates a ventilation gap, facilitating the diffusion of air through the walls, and, therefore, facilitating self-regulation of the humidity level inside the rooms.

When installing the frame, you need to use special dowels that can be screwed into foam concrete walls. If you are finishing rooms with a high level of humidity (for example, an indoor shower bath), you need to choose moisture resistant drywall(it is painted green).

Wooden lining. Used to decorate bathhouses or homes in a natural style. To install it, I also recommend using a galvanized frame (although you can install the lining on wooden slats).

The advantage of this finishing method is that the wood allows air to pass through perfectly and allows the foam block walls to “breathe.” The downside is the need to subsequently treat the wood with varnish or paint. Although, the same drywall also needs to be finished with wallpaper, paint or something similar.

During installation, I advise using vapor-permeable barriers that protect foam blocks from moisture from air vapor generated as a result of human activity. Do not replace them with regular plastic film, since it completely stops air infiltration, that is, you will reduce all the advantages of lining and foam blocks to zero.

In addition to those listed, there are other finishing methods - MDF boards, plywood and so on. However, in essence they are similar to those already listed and their detailed description has no practical meaning.

Summary

Now you know how to finish a foam block inside and out. For those interested, the video in this article provides instructions on how to do the exterior finishing of a foam concrete house with your own hands using siding.

And I wanted to ask the readers, what finish do you like? You can leave your opinion on this issue in the comments.

If you want to express gratitude, add a clarification or objection, or ask the author something - add a comment or say thank you!

Modern private houses and utility rooms are most often built from foam blocks, since they have a low cost, good performance heat and sound insulation.

In addition, they are light in weight and all work is carried out much faster than when using bricks.

To understand what is the best way to decorate the inside and outside of a room, you first need to understand what this material is and what features it has.

If finishing is not completed, this will lead to the following consequences:

Dirt and dust gradually accumulate in the pores of this material;
it will absorb moisture from the air and it will get inside during natural precipitation;
water begins to react with dust and dirt, as a result of which the appearance of such a wall deteriorates, it begins to darken and become covered with uneven spots;
When freezing, the moisture will expand, causing damage to the blocks.

If you have made the blocks perfectly evenly and processed the seams well, then theoretically, you can leave it that way.

But in this case, your house will not only look unesthetically pleasing, but its service life will also be reduced several times, so It is best to carry out both interior and exterior decoration.

One of the main features of foam concrete blocks, which ensures their technical characteristics, is the porous structure.

Due to their high porosity, blocks have low weight and high thermal insulation characteristics.

At the same time, the porous structure of the material reduces its strength and makes its appearance not very attractive, so finishing is required.

Porosity of material provides high moisture absorption, which reduces performance characteristics foam blocks.

After moisture gets into the blocks and they do not have time to get rid of it before frost, it begins to freeze and damage them, so the internal and external the finishing must reliably protect the blocks from the negative effects of moisture.

In addition to the fact that such a house must have an internal and external finishing, in him it is necessary to equip canopies, gutters, window sill drains, properly build the roof and protect the base.

When creating external and internal decoration of walls from foam blocks, it is necessary to take those materials that will ensure the release of steam from the house to the street, otherwise it will accumulate inside the foam blocks.

Outdoor

Each owner decides for himself how to decorate the walls with foam blocks, taking into account both his preferences and financial capabilities.

Any of the materials used has its pros and cons, so in order to make the right choice, you first need to familiarize yourself with them.

Plaster

One of the simple and inexpensive methods of cladding is, which can be ordinary or decorative.

In order for it to adhere better to the surface of the foam blocks, It is recommended to use reinforcing mesh or you can float the surface to open the pores and increase adhesion.

Natural stone has a high cost, while artificial material is cheaper, lighter, has high frost resistance and resistance to fungal development, is less porous, and appearance, it is almost impossible to distinguish it from natural material.

What to do inside the house

The peculiarity is that first it is necessary to carry out their internal finishing, and only then the façade is covered.

It is better to carry out these works in the summer, so that the moisture that gets into the foam concrete can come out.

To waterproof foam blocks, you must use special primers that penetrate the material by 1-5 mm and reliably protect it from moisture.

The inside of a house made of foam blocks can be decorated with more expensive and modern materials.

These can be wall coverings made of wood, bamboo or stone veneer, volumetric options, leather panels.

Modern builders glass blocks are often used, from which partitions, corners or niches in the house, bar counters or work area in the kitchen.

This material allows you to create beautiful lighting; you can make decorative panels from it and decorate your bathroom with it.

Interior plaster

After the primer has dried, apply to the wall install fiberglass mesh, instead of it, you can make notches on the walls, but if this is easy to do on cut blocks, then it is quite difficult on cast ones.

After it dries, the walls can be painted, this will be the simplest and cheap option, suitable for him acrylic paints or silicone and silicate based compounds.

You can also use wallpaper, preferably paper, non-woven or fabric, which allows air to pass through well.

Drywall

Since foam concrete indoors does not like wet processes, which include, It will be easier and faster to finish the walls inside using drywall.

Both plasterboard and gypsum fiber boards are suitable for these purposes.
Before installing the sheathing on the walls, they you definitely need to gurgle, qualitatively seal all seams and cracks.

All that remains is to install the drywall and choose the finish. If you use wallpaper for painting, then you don’t have to putty the walls, but only seal the seams.

Today, most low-rise buildings are built on the basis of wall blocks. The interior decoration of a house made of foam blocks has a number of nuances that will need to be taken into account during work. Foam blocks have gained great popularity due to their low cost and excellent characteristics. Working with such material is not particularly difficult, so even a beginner in the construction craft can cope with it.

Advantages of using foam concrete blocks

Foam blocks have gained great popularity in construction due to their undeniable advantages. These include:

Large block sizes, which can significantly speed up the construction procedure.
The light weight of the material allows you to reduce the labor intensity of the work and perform it without the use of special construction equipment.
High rate mechanical strength products.
Excellent thermal insulation and sound insulation characteristics.
Protection from various temperatures.
Non-combustibility of blocks.
The products are based on environmentally friendly components, so they are completely harmless to the human body.
Easy finishing using hand tools.
Walls lined with this material have an excellent level of vapor permeability, which allows them to breathe.

It is worth considering that the interior decoration of a house made of blocks will require the creation of waterproofing. Since such material has a porous surface, moisture accumulated inside it can lead to loss of thermal insulation qualities. Because of this, the coating may crack, and there is also the possibility of condensation, which also leads to deformation and destruction of the blocks.

Nuances of wall cladding

Processing walls made of foam blocks has its own differences. The smooth surface of the material and its composition do not allow the use of simple cement-sand mortars, which have an insufficient level of adhesion. For good adhesion, you will need to first apply primer mixtures that will penetrate the foam concrete, reduce hygroscopicity and increase adhesion.

Source chrome-effect.ru

On our website you can find contacts of construction companies that offer finishing and insulation services for houses. You can communicate directly with representatives by visiting the “Low-Rise Country” exhibition of houses.

The quality of the cladding of such material very much depends on compliance with the technology of its installation. If a special adhesive composition was used during the construction of the walls, then the interval between the blocks will be no more than 3 mm, which will create a smooth surface and simplify its further finishing. Also, when laying foam concrete, a reinforcing belt must be used for every 4-5 rows of material. It will ensure good surface strength and prevent possible shrinkage. If reinforcement is not performed, after some time shrinkage can lead to deformation of the blocks and destruction of the inner and outer protective layer.

Important! The internal cladding of the foam block should be carried out first, only after this the external work is carried out.

Wall treatment should be carried out in dry, warm weather, preferably in summer. This will allow the wall to dry well, which is important for further waterproofing. During the cold season, moisture in the pores may freeze and remain inside the blocks.

Tools for internal cladding of foam blocks

When decorating the interior walls, you will need to prepare everything you need in advance. You will need the following tools:

Electric drill and screwdriver for making holes.
Paint brush and roller for applying solutions.
Spatula and construction trowel.
Construction mixer for mixing the composition.
Hammer and mallet.
Construction knife.
Scissors, hacksaw for metal processing.
Building level and a tape measure for taking measurements.

Material options for finishing foam blocks

It is possible to veneer a foam block with high quality only by ensuring good protection from moisture. To do this, before decorative processing Certain procedures are carried out to level the surface, improve the level of adhesion and protect the blocks.

Source my-71.ru

Protective leveling solutions are applied in several layers. The first step is priming with a special mixture, which was developed specifically for foam concrete. You will also need to perform waterproofing to prevent the formation of condensation. It is worth considering that steam appears in all rooms, and not just in the kitchen or bathroom. People also create steam with their breath. A fairly popular vapor barrier is penofol, which is roll material based on polyethylene, covered with aluminum foil on both sides.

Further cladding technology depends only on the selected material. What is the best way to decorate the inside of a house made of foam blocks? The following options can be used for this:

Installation plasterboard sheets or chipboard with further decorative finishing.
Plastering surfaces for painting or whitewashing.
Wallpapering.
Finishing with clapboard or other wood-based materials.

Installation of drywall sheets

Finishing with plasterboard is a fairly popular solution. This choice will allow the use of a large amount of vapor and heat insulation materials, and will also provide an additional waterproofing layer. The basis of the procedure is covering the surfaces with plasterboard over a pre-prepared sheathing based on wooden beams or a metal profile. The frame is created by fastening vertical components at intervals of 45-55 cm. Additionally, they can be strengthened with horizontal jumpers.

Source ms.aviarydecor.com

The work of installing drywall on a foam block surface consists of the following steps:

Preparation, which consists of applying a primer and one layer of plaster mixture.
Installation of vertical parts of the sheathing. To do this, you will need to prepare an aluminum-based profile or a wooden beam with dimensions of 20 by 40 or 40 by 40 mm. Fastening is done using self-tapping screws.
Creation of a hydro-, steam- and heat-insulating layer. The first step is to install thick roofing material between the sheathing posts. Next, if desired, a thermal insulation layer is applied. It may be based on mineral wool, polystyrene foam or other solutions. Finally, the materials are covered with a vapor barrier. All elements are fastened using dowels, screws or glue. It must be taken into account that there should be no intervals between the protective layers and the sheathing elements.
Next, the drywall is fastened to the sheathing using screws or metal screws. You will first need to make holes in the sheets for fastening to prevent possible deformation. All fasteners must be well recessed into the material. Also, when installing drywall, you will need to leave empty space between the vapor barrier layer and the sheet to ensure good ventilation.
Finish lining sheets are produced using traditional technology.

Facing foam blocks with plaster

Any option for wall decoration first of all requires flat surface, which is extremely important for block structures. Leveling can be easily accomplished by applying a layer of plaster. The work consists of the following stages:

Preparing the walls. First you will need to thoroughly clean the wall of dirt, adhering mixtures, grease or oil stains. If there are large deformations, they will need to be repaired.
Primer. A special solution is applied using paint brush or roller. The layer should be thin, the composition should be distributed over the entire surface. It is extremely important that the mixture penetrates 3-5 mm inside the foam block. Wide voids between blocks are processed using glue.
Grid installation. After the primer has completely dried, the mesh is installed on the wall. The most commonly used mesh is fiberglass mesh. This procedure will increase the strength of the finish and significantly increase the level of adhesion of the mortar to the wall.
Applying plaster. The main goal when performing such finishing is high-quality leveling of the surface. As plaster, it is best to use dry compositions for interior work on a gypsum or cement base. Experts also often use sand-cement mixtures prepared with their own hands. In such cases, the proportions are 3 to 1. The technology for applying plaster depends on the further finishing. So for future installation of tiles, one layer of plaster will be enough. For painting or wallpapering, it is best to apply the solution in 2 layers with an external and finishing coating, which guarantees the ideal evenness of the wall. In this case, the main layer should have a thickness of about 2-3 mm, and the leveling layer should have a thickness of 10-12 mm.

Conclusion

The cost of interior finishing of a house made of foam blocks depends entirely on the materials used. You will need to take into account the price of the primer and other required products. The most economical solution is to install plasterboard sheets. This process does not require prior plastering. Also, in the future it will be possible to stick wallpaper on the drywall, apply paint or decorative plaster.

The right decision is to draw up a project in advance repair work taking into account all costs. In many cases, it is advisable to seek help from specialists - this will help reduce unnecessary costs for the purchase of excess material, and also ensure high quality the final result.

Modern low-rise construction has long been unimaginable without wall blocks. Brick, of course, is a good thing, but it high price, and considerable weight, gradually pushes this material into the background.
Foam blocks steel a worthy alternative brick. We will talk about their properties in our article, as well as the methods by which the interior finishing of a foam concrete house is carried out.

Foam concrete is relatively new building material. Initially, it was intended for thermal insulation of buildings and structures, but after some time, having established itself as a strong and durable material, it began to be used constructively.
So:

Thanks to the porous structure of foam blocks, the walls of a house built from them breathe. It is this property that ensures high level thermal insulation of such houses.
Foam concrete absorbs moisture more strongly than regular concrete, so you need to work with it taking this feature into account.
In order for the interior decoration of a house made of foam blocks to be of high quality, first of all, the walls must be laid without errors. The most common mistake made during the construction of such a house may be the use of the wrong masonry mortar.
For laying foam blocks there is a type of mortar, which is essentially an adhesive mixture.

The second mistake that can ruin all your efforts on interior decoration of the house is the absence of reinforcing belts in the block masonry. And they need to be done not only in window sill areas, but also along the entire height of the wall, every four to five rows.
Block house, like any other, shrinks. The reinforcement in the masonry reliably fixes the walls and reduces the likelihood of cracks appearing on them.

Due to the fact that the blocks are larger in size than the same brick, it takes half as much time to build a house. Therefore, construction budget savings are obtained not only due to the cheaper cost of foam blocks, but also due to reduced labor costs for their installation.
There is another chance to build a house at the lowest financial cost. Foam concrete blocks You can make it yourself right on the construction site.
Of course, this will require equipment: a steam generator, mixer, compressor.
But its purchase is more than compensated by savings on the cost of the material and the costs of its transportation. Foam concentrate for making blocks is sold dry and simply diluted with water, according to the manufacturer’s instructions.

In any case, if you build a big one two-storey house, such as the one in the photo above, producing blocks on site makes sense. If you are interested in this issue, go to the manufacturer’s website, read technical literature on this topic, watch the video.
A variety of methods are used to decorate the facades of such houses; finishing a house from foam blocks from the inside is what we will talk about today.

Preparing walls for finishing

Finishing houses made of foam blocks has its own nuances. Brick, wooden or, for example, reinforced concrete walls do not require double-sided waterproofing.
The same cannot be said about walls made of foam concrete blocks. Of course, this type of concrete does not absorb moisture as much as aerated concrete, but still, more strongly than other wall materials.
So:

Internal finishing work is carried out first, facade cladding is done after them. This applies to all buildings constructed from cellular concrete.
It is advisable to finish a house from foam blocks in summer time, in any case, all wet processes: screeds, self-leveling and heated floors, tile laying. Then the moisture coming out through the concrete cells will dry out and not freeze in them.
The surface of the block wall is cleared of mortar deposits and primed. In this case, soil compositions specially designed for cellular concrete are used.
The soil penetrates into the thickness of the block from 1 to 5 mm, creating a barrier to moisture penetration.

Plastering and finishing

In terms of surface unevenness, block walls are not much different from brick walls. There are many lungs building mixtures, intended for plastering walls made of foam concrete blocks.
When purchasing, you need to consult which type of plaster is suitable for cellular concrete.
So:

After the primer layer has dried, a fiberglass mesh must be mounted on the wall. Fasten it with dowels so that the mesh fabric fits tightly and without gaps to the wall.
You can, of course, do without a mesh by making notches on the surface of the blocks - fortunately, they are soft enough for this. But, firstly, notches can only be made on cut blocks.
But a cast block does not lend itself well to such processing. In addition, they are very smooth, and the plaster will not adhere well to them.

It is even recommended to pre-treat cast blocks with a file to make their surface rough. The mesh not only facilitates the plastering process - it serves to strengthen the wall itself.
Especially if the wall has a large area. Therefore, saving on the purchase of a mesh is inappropriate here.
When it comes to finishing plastered walls, there are many options. We present to your attention good example This type of finishing is the interior finishing of a foam block house by painting the walls.

For such walls made of cellular concrete, ordinary acrylic paints are not suitable. It is better to take paints based on silicate or silicone - they have higher vapor permeability.
IN in this case, together with matte paint, decorative interior paint of a similar shade was used, which was applied fragmentarily, inside a figure made on the walls with a polyurethane frieze. A frieze was also used to decorate the ceiling of the room.
Block masonry is great for decorating a loft-style room. That is decorative surface The walls are unplastered masonry.
It is thoroughly cleaned, sanded, primed, and decorative jointing is performed. The top surface of the blocks can be coated with colorless varnish and hydrophobic impregnation.

Finishing a block house in the loft style

Usually, in a room decorated in this style, only one wall is left unplastered. The remaining surfaces are finished according to all the rules.
Such an interior should also have ultra-modern design elements that contrast with the rough-finished wall. In our example this is original staircase, leading to the second floor.

The interior decoration of a foam block house, of course, can also be done using wallpaper (see Wallpaper decoration: choosing the right one). If they will be glued to plastered walls, you should not use linkcrust or vinyl options.
“Breathable” wallpaper is best suited for this purpose: non-woven, paper or fabric. If you want to glue wallpaper, it is much easier to do it on walls covered with plasterboard.
This is what we will talk about next.

GKL in home decoration

Houses built from cellular concrete do not like wet processes in interior decoration. And plastering such walls is not cheap at all.
It is much faster and more convenient to cover the walls with sheets of plasterboard. It can also be used to make internal partitions, both those involved in planning and decorative ones.

So:

You can use not only gypsum boards, but also gypsum fiber sheets (GVL). Their strength is much higher, which allows working niches under household appliances, freeing you from the need to purchase certain types of furniture.
And this is also a significant saving.
It is impossible not to say that with the help of drywall you can create a magnificent suspended ceiling with backlight, in internal space which will hide all the wires and cables. So the answer to the question: “What is the best way to decorate a house from foam blocks?” - obvious. Drywall of course!
As we have already said, the walls must be primed and the seams between the blocks must be puttied. It is better to insulate the walls of block houses from the outside.
But if they are planned to be plastered or faced with stone or ceramic tiles, thermal insulation will have to be done from the inside.
In the southern regions this is unlikely to be necessary, because foam concrete itself is excellent thermal insulation material. But in areas with harsh climatic conditions, insulating the walls will not be superfluous.

In order not to clog the tightly breathable surface of the walls, waterproofing film There is no need to mount it on block masonry. The primer for cellular concrete itself is a good insulating agent.
It is also better to choose breathable insulation. Most good choice for walls made of cellular concrete there will be basalt or fiberglass wool. It’s just better to take not rolled material, but in the form of slabs - it will be much more convenient to mount it on the wall.
The work of installing a thermal insulation layer will be much simplified if you choose an insulation option with a vapor barrier layer applied to it at the factory.

A frame is mounted from an aluminum profile, into the cells of which the insulation is placed. The width of the slabs must correspond in size to the pitch of the profile.
Better yet, be one or two centimeters wider. Then it will tightly fill the space of the frame.
The insulation boards are laid with foil inside the room and fixed to the wall with glue.
After that, gypsum plasterboard sheets are mounted on the frame. We will not talk now about all the nuances of constructing the frame, its cladding and preparing the drywall surface for further finishing. There is a detailed article on this topic on our website.
Let's just say that for finishing it is better to take thick textured wallpaper for painting. Then you won’t have to putty the entire surface of the drywall - it will be enough to carefully seal the seams between the sheets.

Wall painting can be done without wallpaper for painting. But in this case, it is necessary to putty the gypsum board over the entire surface.
These two types of finishes can be combined in the interior, as well as used self-adhesive film for finishing some fragments of a wall or ceiling structure.

A little about interior design

Decorating the inside of a house made of foam blocks can also be done with other materials. For example, a tree.
In this case, it is not sheets of plasterboard that are mounted on the frame, but lining boards or wooden panels:

It all depends on what aesthetic effect of the interior you want to achieve. Let's say you need to decorate an office.
Such a room is most often designed in classic style. Wooden panels, in this case, are ideally suited for wall decoration.

We have presented an excellent example of office interior design. Strict furniture with finishing in harmony with the wall panels, leather armchairs, coffered plaster ceiling with wooden elements, parquet floors covered with a carpet with geometric patterns - everything is strict and tasteful.
Such an interior is simply conducive to mental work, helping to concentrate. There is no shame in receiving a guest in this room.
The choice of finishing option may depend on the design of the house and its layout. If, for example, you have cottage without an attic or ceiling, wood will help you create an unusually beautiful ceiling.

Anyone can participate in this finishing structural elements roofs: beams, racks, rafters. Despite the fact that the roof insulation was carried out externally, it is also carried out internally. This work is similar to what we described above for walls.
Only before installing the insulation, waterproofing is installed using a roll membrane.
The planking is done over a wooden sheathing, after which the structure is painted. All wooden elements involved in the cladding must be treated with an antiseptic primer before installation, which protects the wood from moisture and exposure to rodents and insects.

If there is a ceiling in the house, then wooden beams or polyurethane false beams can be mounted to it, imitating them. The hollow design of these beams allows them to be used as cable channels, which greatly simplifies the task of routing wires along the ceiling.
The space between the beams can be sheathed with clapboard or, as in our example, with plasterboard in which the Spotlights. Its surface: both on the ceiling and on the walls, is painted, and only a fragment around the fireplace is lined with decorative stone.
The interior decoration of a house made of foam blocks can also be done using more modern materials, such as wall coverings with wood, bamboo or stone veneer, leather panels or 3D volumetric options.

Glass blocks are increasingly being used in the decoration and planning of premises. Of these they perform interior walls and partitions, fencing of bar corners, lining of niches and columns, working walls in the kitchen.
What is most attractive about this type of decoration is the possibility of providing beautiful lighting for the structure, making decorative panels, and tiling the bathroom.

Interior decoration: houses made of foam blocks, or built from other structural materials, have hundreds of options. They allow you to create an interior that no one else will have.
Moreover, in a private house - this is not standard apartment, in which there is nowhere to turn around. In such a house, you can make the layout at your own discretion, using not only drywall or glass blocks, but also curved glass.
