On the issue of waterproofing a bathroom in wooden house you need to approach it with special talent and mathematical intelligence. Unlike man-made building materials, porous wood is a unique material that functions as an air humidity regulator. The pulp of the tree can swell during prolonged downpours and dry out during heat without precipitation.
From constant exposure to moisture and dampness, wooden structures can rot, mold, and be destroyed by fungus. To protect wood from exposure to humid air, steam and water in the bathroom, maintaining its original appearance load-bearing structures, it is recommended to use only compatible waterproofing materials.
Features of bathrooms in wooden houses
Lavatories and showers in wooden cottages are very different from those we are used to seeing in apartments in brick and monolithic houses. And although they are similar in appearance, behind the decoration there is a complex technical calculation and a lot of materials that are not typical for city apartments.
- To place a bathroom and toilet, you should choose a room with an outer wall for the ventilation shaft or pipe.
- When installing gas boiler, washing machine, sinks, bidets, laundry cabinets, other pieces of furniture and plumbing, you need to allocate at least 6 square meters. m. area.
- The placement of a toilet, washbasin, bathtub or shower cabin is carried out in accordance with ergonomic standards: 700 mm of space is left in front of the point, at least 200-250 mm on the sides.
- To avoid a water supply accident, it is necessary to insulate the base of the floor and pipes using thermal insulation materials, and also organize a drain valve.
- To avoid an accident in the sewer system of a SIP house, it is necessary to install damping devices and provide for the creation of compensation gaps in order to protect the pipes from displacement during shrinkage of the cottage.
- From the options for finishing a bathroom in a wooden house, it is necessary to exclude flammable materials, as well as conifers trees: pine, spruce and larch, whose resins, when heated from water vapor and a boiler, negatively affect the skin, lungs and bronchi.
Waterproofing bathrooms
Proper waterproofing of a bathroom in a wooden house is the secret to the durability of load-bearing structures made of wood and wood fibers. When building houses from SIP panels, craftsmen recommend using the most elastic waterproofing materials with the maximum coefficient of hydrophobicity and adhesion. Experts offer two types of materials to protect surfaces from the harmful effects of water in a shower or bath.
Pasted waterproofing
Pasted insulators have little popularity, since they are difficult to install in a small frame room. Of all the materials in this group, preference is given to an imported bitumen-polymer membrane on a self-adhesive backing. The membrane is applied using hot or cold mastic in several layers.
Another important disadvantage of pasting is the presence of seams between the canvases. Under interior decoration a bathroom in a wooden house will somehow accumulate condensation. However experienced craftsmen found effective solution to solve this problem - they lay the canvases overlapping and fill the joints with hot bitumen and pitch, having previously covered the heated bitumen with reinforced fiberglass.
Coating waterproofing
This group of insulators is more popular and consists of bitumen-polymer mastics under the screed and cement-polymer mastics for laying over the screed. It's elastic waterproofing coatings, consisting of two components: a powder of inert fillers and anti-water binders, as well as an aqueous dispersion of acrylic polymers. Best performance hydrophobicity shows rubber- bitumen mastic. It remains constant after freezing even when the geometry of the building structure is deformed.
As in the case of pasting, additional strength of the coating waterproofing is provided by a reinforcing mesh made of fiberglass. It is laid between the first and second layers of insulation. In addition, moving parts of the house, especially the joints of walls, floors and ceilings, must be reinforced with elastic sealant tape.
Floor materials
If you want to leave the floor wooden, you must use moisture-resistant thermal wood as a floor covering even at the construction stage of the house. It does not change volume under the influence of moisture and changes in air temperature, which means it will not damage the floor several years after installation. Suitable wood types for wooden flooring include teak and cork. Despite the high percentage essential oils and amazing moisture resistance, it is recommended to treat the boards with deck varnish.
If floor joists are already installed in the house, waterproofing the bathroom floor begins with laying two layers of waterproof plywood. A self-adhesive membrane or polymer-bitumen mastic with a high elasticity coefficient is placed on the sandwich. Then they organize reinforced screed, on top of which the finishing material is laid on waterproof glue.
If you plan to install an electric or water heated floor in a SIP house, coating waterproofing should be applied over the screed.
Wall materials
For high-quality waterproofing of walls in the bathroom, glass-magnesium sheets or aqua panels based on cement or extruded polystyrene are used. When choosing aqua panels, it is important that they are reinforced with fiberglass on both sides and coated with a plasticizer. This material is much more moisture resistant than, for example, heavy drywall. And so that there are voids between the wall and the base for ventilation of the wood, aqua panels and sheets are mounted on the frame using dowels and tile adhesive.
Bathroom finishing
Finishing a bathroom in a wooden house follows a similar principle. The materials chosen are those that are not afraid of direct contact with drops of water and changes in air humidity.
Floor
Experts recommend using ceramic tiles or tile. This obvious material for finishing bathrooms and restrooms has been tested by time. It does not allow water to pass through, since it has no through pores, and when correct operation does not crack for several decades in a row. It is best to lay tile elements on polyurethane adhesive composition, and use epoxy grout to grout the joints.
An important nuance is the installation of an emergency drain in the floor. To organize a spare drain, you need to make the screed at a slight angle so that the water drains naturally. A drain ladder is installed at the lowest point of the slope.
Walls
Ceramic, polystone and glass tiles are also used to decorate bathroom walls in a wooden house. There are no restrictions here: you can purchase tiles from any manufacturer with a glossy, matte, polished surface, with or without a glazed coating. There are no restrictions on the size of tiles, borders, panels and other decorative elements.
If the bathroom will be ventilated by opening a window like a bathhouse or dressing room, it is recommended to use frost-resistant tiles and mosaics. But it is better not to install rectified tiles in the first years after the completion of the house. Smooth walls covered seamless tiles, may become covered with waves as the wood shrinks.
Bathroom finishing wood panels- Another one good option registration hygienic room. Gained great popularity in Russia Wall panels from MDF - medium density fiberboard (Medium Density Fiberboard). Having a visual resemblance to chipboard, the boards are distinguished by a smoother structure and a binder - lignin.
Finally thick enough wooden walls can be sanded, rubbed and coated with moisture-resistant varnish. In this case, you will save significant money on finishing the bathroom and toilet. Due to the lack of a thermal insulation layer, this advice is not suitable for all owners. frame houses, especially those living in the northern regions of the country.
Ceiling
To finish the bathroom ceiling wooden clapboard must be approached with extreme caution. When it comes to pine, spruce and larch, it is best to avoid using materials based on natural wood of these species due to the high content of dangerous resins. At the same time, finishing the ceiling of a washroom or shower with such species as alder and aspen is absolutely safe for health. The low hygroscopicity of wood makes it an ideal material for decorating the bathroom ceiling if you like hot water and long water procedures.
Options for finishing a bathroom in a wooden house do not end with materials made from natural raw materials. Lining can be not only wooden, but also plastic, including those with imitation wood texture. It will be suitable as decorative cladding ceiling if you want to use an unusual color. Natural wood is limited in color palette, while polyvinyl chloride panels can be presented in any shade.
One of the latest trends is mirror ceiling panels and chameleon lining. They are not afraid of moisture and heat, and are easy to install using the tongue-and-groove and tongue-and-groove methods. Unlike wooden products, plastic panels They reduce the height of the bathroom a little less, so they are especially relevant in low rooms.
Stretch ceilings made of polyvinyl chloride, polyester and polyurethane are not recommended to be installed immediately after the construction of the frame of a residential building. Otherwise, the shrinkage process may deform the canvas, which will lead to the need to dismantle the damaged ceiling and work in a new way.
Ventilation
The interior decoration of a bathroom in a wooden house does not end with laying multi-layer waterproofing and installation decorative materials. The most important stage, without which the adoption of water procedures can be dangerous to human health and the finishing of the cottage, is the installation ventilation unit. It is recommended to install ventilation in the attic, observing a number of rules.
- Ventilation equipment should not come into contact with wood - pipes and other elements are mounted on steel brackets.
- The ventilation duct must be made of non-combustible materials and fasteners.
- The ventilation duct is laid only through compensation holes, which prevents the shaft from moving during the process of slow shrinkage of the frame.
- The ventilation duct is equipped with fire dampers to block air flow in the event of a fire.
To eliminate the effect of air stagnation and activate the natural flow of oxygen, you can use a valve supply ventilation. A small device is mounted directly in the wall of the room intended for the bathroom. Street air circulates in the bathroom and is removed through the hood, providing constant air exchange and removing excess moisture and odors from the hygienic room.
Conclusion
Now you can imagine how the process of waterproofing and repairing a bathroom at home occurs. Materials for finishing latrines and bathrooms in a wooden cottage differ in composition, color, design, size and method of fastening, but they are united by several important characteristics. All of them must have a high coefficient of hydrophobicity and adhesion, and rough waterproofing materials must be elastic and free from the slightest joints and pores.
A wooden house is essentially alive. He always seems to be on the move. It started to rain - the wood swelled, the sun came out - it shrunk a little. In addition, this is a natural material, and nothing “natural” is alien to it: wood rots, molds, is attacked by fungus, and in the tropics it is eaten by termites. Termites for middle zone, however, the problem is not urgent, but shrinkage over time noticeably changes the geometry of the entire building. So, arranging a bathroom in a wooden house is not a trivial task.
Proper waterproofing - perhaps the most important question for which a summer resident will have to look for an answer.
● Firstly, you need to try to apply the latest technologies and use the most elastic waterproofing materials that have high water-repellent properties (hydrophobicity), water resistance and good adhesion to any surface (high adhesion).
● Secondly, it is reasonable to entrust the work to professionals, or to carefully follow the manufacturer’s instructions.
Today, pasting and coating materials are used to waterproof floors and walls in the bathroom.
Pasted waterproofing It is quite difficult to use in a bathroom. But if you still settle on it, then it is most convenient to use a bitumen-polymer self-adhesive membrane. The highest quality membranes are produced abroad, but they cost about 3 times more than their domestic counterparts.
Therefore - perhaps still at the project stage– it is worth focusing on the technology of coating waterproofing. If only because this type of waterproofing is characterized by high, and most importantly, stable elongation and recovery rates. This is especially true for houses built of wood.
Coating waterproofing These are polymer-bitumen mastics that go under the screed, and polymer-cement mastics that are applied on top of the screed. Capillary rubber-bitumen mastic has very good performance, the protective layer of which is preserved even with deformation building structures. It can be applied to the screed.
Polymer-cement mastics– These are two-component elastic waterproofing coatings. One component is a powder mixture containing moisture-proof binders and specially selected inert fillers. The other is an aqueous dispersion of acrylic polymers. When mixing the components, a high-tech composition is obtained that has excellent adhesion to any surface.
The bathroom in a wooden house is usually classified as a so-called “problem” place, causing its owners a lot of trouble. And, indeed, the high humidity of this auxiliary room has a destructive effect on adjacent rooms, making them unsuitable for permanent housing. That's why reliable waterproofing bathroom in a wooden house is a prerequisite for creating normal conditions to live in it.
Difficulty in protecting individual elements from moisture wooden buildings due to the fact that the use of traditional waterproofing materials (roofing felt, for example) is not always effective and does not provide complete insulation.
However, with the advent of modern high-tech materials that provide effective protection wooden structures from moisture, all issues regarding the organization of waterproofing of such a bathroom are resolved quite simply. In this article we will look at methods that will not only help to perform high-quality waterproofing, but also transform the appearance of this room.
The domestic building materials market currently has big choice waterproofing materials, which (in accordance with the technique of their application) are conventionally divided into the following groups:
- paint coatings in the form of mastics and emulsions, made on the basis of bitumen and polymers and creating a reliable moisture barrier after application;
- glued materials on the same basis, having a roll or film version (for gluing them on wooden surface a special heated mastic is used);
- cement-based liquid compositions (hot bitumen, pitch);
- special impregnating coatings made of water-repellent cement with an additive chemical reagents and crushed sand.
The basis for applying waterproof liquid formulations Pre-laid waterproofing of sheet or roll type with a layer of reinforced fiberglass laid over it is used. This combination protective materials forms an ideal seamless coating that meets all waterproofing requirements.
Impregnating materials, after being applied to the surface of wood, penetrate into upper layer the latter and make it waterproof.
This type of waterproofing is very rarely used in residential premises.
We also note that when organizing work to insulate a bathroom in a wooden house, separate waterproofing of the floor, its walls and ceiling is assumed. Let us consider the procedure for carrying out each of these operations in more detail.
Floor waterproofing
Do-it-yourself insulation of a bathroom floor is the most labor-intensive of the procedures included in the complex of waterproofing works organized in a private home. But at the same time, you can always use the waterproofing option, the implementation of which will be quite cheap and simple.
The order of work performed with the above choice is usually presented in the following form:
- first on wood flooring, previously cleared of foreign objects and small debris, a whole piece of PVC film (or the thinnest linoleum) is laid as waterproofing, the edges of which are folded overlapping the walls by about 15–20 cm;
- In order to level the laying plane at the corners, the material is cut and then poured silicone sealant. For reliability, the edges of the linoleum are fixed to the walls using a liquid bitumen composition or mastic;
- after this, reinforcement in the form of a fine-mesh mesh is laid on the linoleum, over which a regular mesh is then made.
Using this method, it can also be made from well-known rolled materials containing bitumen (from roofing felt, for example, or using a fused roofing). But such an approach will be more expensive, especially if you use modern materials high cost.
When using roofing felt, the surface of a wooden floor is first treated with mastic using a roller or brush, and then sheets of material are placed on it with an overlap of approximately 20–25 cm. In a situation with a built-up roof, you will need a special burner, which is used to glue or “stitch together” adjacent sheets. In this case, the blanks used are laid in several layers so that each of them is perpendicular to the previous one.
In this case, just as when using linoleum, it is necessary to make a slight overlap of the material on the walls, and carefully treat the cut corners with the same sealant.
Preparing walls for finishing
The walls of a bathroom in a wooden house, as a rule, are laid out either from round logs (rounded) or from ordinary timber. At frame structure buildings they can be finished edged board or OSB boards, For example. In all cases, except the last one, special preparation of the walls is required, which boils down to their leveling for the purpose of subsequent laying on the surface or PVC panels.
Before you do this part preparatory work, first of all, you will need to prepare a special frame for. Waterproofing measures are reduced to in this case to the use of a special moisture- and vapor-proof film laid between sheets of drywall and a wooden wall.
When finishing walls with OSB boards special training There is no need to apply a layer of waterproofing. In this case, the painting method of forming a protective layer with preliminary preparation wall surfaces by sealing the seams formed on the surface. In this case, the sealant used and itself waterproofing material should belong, if possible, to the same class, that is, have a similar basis. Protective mastics or emulsions are applied to the surface to be finished in several layers, alternating the direction of movement of the roller or brush (horizontally and vertically).
After they dry, an absolutely impenetrable waterproofing coating is formed, on which you can lay the finishing material of your choice.
TO protective treatment It is advisable to proceed with the walls of a shower room in a wooden house only after waterproofing its floor has been completed.
Ceiling insulation
The technique for waterproofing the ceiling in a bathroom is not much different from the techniques already described and also depends on the class of material used in its arrangement. So, on a ceiling made of ordinary lining it will be enough to apply a special water-repellent impregnation; in this case, a vapor-proof film must be placed under the frame used for cladding. For any other ceiling finishing option, you can use mastic or a special impregnation used to protect the base from moisture.
In conclusion, I would like to note that a competent approach to solving the problem of waterproofing bathroom in a private wooden house will allow you to avoid a number of troubles associated with leaks that lead to dampness in the basement and the formation of smudges on the walls of adjacent rooms. The method described in the article is not the only one. Depending on what kind of interior you have planned for the bath, the methods of waterproofing will differ.

- sprayable;
- injection;
- penetrating;
- painting;
- plastering;
- coating;
- pasting.
The bathroom floor in a wooden house is waterproofed using painting, coating or roll methods. Choice waterproofing coating It’s better to entrust it to an experienced specialist, since high-quality waterproofing of a bathroom in a wooden house helps you forget about many problems.

What should you pay attention to when arranging a bathroom in a wooden house?
- In a wooden house, it is better to place the bathroom on the ground floor. If the house has several floors and bathrooms, even at the construction stage the floors should be strengthened by installing additional beams under the future bathroom. It is better to entrust the calculation of the load and the required reinforcement to a competent specialist.
- It is more convenient to place rooms with high humidity on top of each other and carefully insulate both rooms and floors. In the event of a leak, this will cause minimal damage; among other things, such a layout will reduce the cost of plumbing.
- It is necessary to provide for a height difference at the site of the future bathroom; this will greatly facilitate subsequent finishing.
- It's not just the floor that needs waterproofing, be sure to protect the walls and ceiling.
- Provide good ventilation, this will help avoid many problems.
- Waterproofing may be needed not only in the bathroom; take the time to protect the kitchen, bathrooms and rooms where the washing machine is located.

Waterproofing the floor in a wooden house, in a bathroom, is carried out in several stages.
On our website you can find contacts construction companies who offer house design services. You can communicate directly with representatives by visiting the “Low-Rise Country” exhibition of houses.
Preparatory work
First, the foundation is thoroughly prepared. It is cleaned of debris, dirt and dust. To seal cracks, use a special wood mastic. Wooden logs It is advisable to treat it with an antiseptic and special protective impregnation.
A layer of expanded clay is placed between the joists for insulation and additional sound insulation, mineral wool, expanded polystyrene or ecowool based on flax fiber. The choice depends on the preferences and financial capabilities of the home owner.
The insulation is covered with sheets of plywood with moisture-resistant impregnation or cement-bonded particle boards.
Wooden sheets must be impregnated, this will significantly extend their service life Source indigostroy.com
Next, the slabs are processed waterproofing primer For additional protection coverings. The primer must dry well. It is necessary to ensure that dust and dirt do not enter the room during the drying process.
Important! cement screed It is better not to do this in wooden houses due to the high load on the floors.
The primer must be applied to the walls to a height of 20-25 cm around the entire perimeter of the room.

Floor waterproofing
It is produced by laying strips of rolled waterproofing or using coating compounds. It all depends on the choice of the consumer.
Choosing rolled materials Please note that self-adhesive waterproofing does not require heating. For a wooden house this is a significant plus. The rolls are cut into strips, which are overlapped to prevent water from getting between the joints of the sheets. The overlap is carefully coated with bitumen mastic.
Pasting the wall around the perimeter is done after finishing work on the floor. Waterproofing strips are cut 30-35 cm wide. The canvas is glued to the wall, placed on the floor, which is treated with mastic. Waterproofing for the floor in a wooden house is done to create a high-quality water barrier in the bathroom. Its prerequisite is complete sealing of the resulting trough.

Painting or coating waterproofing
There are several types on the market for this application.
Liquid bitumen mastic. It is completely ready for use, easy to use, and quite cheap. Liquid waterproofing of a bathroom in a wooden house is applied in 2 layers; when applying, you can work with a regular wide brush. The second layer is applied after the first has completely dried, usually complete drying time takes 6-8 hours. Corners, joints between the wall and the floor, and places where pipes exit are additionally covered with a special waterproofing film; you can simply increase the number of layers of mastic in these places.
Paste-like bitumen mastic with polymer additives. It has a thick consistency, is applied in a thicker layer, and additionally levels the floor. 2 applied layers provide excellent protection for the room. For greater strength, you can use fiberglass reinforcing mesh.
The cost of this composition is slightly higher, but it has greater strength and elasticity.
The mastic is completely ready for application Source satu.kz
Cast floor waterproofing
Cast waterproofing of a bathroom in a wooden house can be done hot or cold.
The hot application method must be performed with extreme caution. Plastic compositions based on bitumen with this method of application are heated to a temperature of 50-120 ° C, so it is better to entrust such work to a specialist.
Cold way. This is a very popular self-leveling floor today, consisting of epoxy mixture, liquid glass or high-strength polymers. If the first 2 types are usually a self-leveling base for subsequent laying of finishing materials, such as laminate, on the floor, then a polymer self-leveling floor forms a beautiful, high-quality coating, which, in addition to excellent protective properties, Very beautiful. It can serve as an independent decoration for the bathroom interior. Of course, this is not a cheap coating, but it is very high quality and durable.

Waterproofing concrete floor
Waterproofing a concrete floor can be done using all of the above methods. New types of waterproofing concrete base is applied to concrete with a special plaster mixture with polymer additives. After hardening, this mixture forms a durable moisture-proof coating. For optimal results, carefully follow the instructions for preparing and applying the solution.
More recently, penetrating waterproofing has appeared. Components of a special composition penetrate into the pores of the concrete base, forming waterproof crystalline compounds. The structure of the concrete does not change; the composition protects the concrete not only from moisture, but also from adverse chemical influences.

How to make a bathroom floor
High-quality waterproofing of a bathroom in a wooden house allows you to choose almost any floor covering for it. Tile, stone or linoleum are widely known and often used for bathroom floors.
The development of technology has made it possible to use special moisture-resistant types of laminate for flooring. Today, waterproofing under laminate is usually done using a self-leveling floor, so that such a floor will last a long time when purchasing, pay attention to the markings.
It is also quite possible to make wooden floors in the bathroom. You just need to take into account that special types of wood are selected for rooms with high humidity. Teak, larch, cedar, bamboo, and some other species are excellent at resisting moisture. Everyone chooses depending on their taste and financial capabilities. Consulting an experienced specialist will help you make the right choice. Do not forget that waterproofing a wooden floor requires special attention.

Conclusion
The abundance of materials for construction and finishing, which did not exist just yesterday, makes it possible to realize the wildest fantasies of the consumer. A modern wooden house combines excellent quality and environmental friendliness. A competent approach to construction and professional work at all stages ensures the highest comfort for the people living in it.
Houses made of wood are rightfully considered the best option housing: they are environmentally friendly, have a special microclimate and are well ventilated. However, wood fiber has a drawback: it quickly absorbs moisture, retaining it inside for a long time. At the slightest increase in temperature, the material begins to rot, interior spaces It affects mold, which is quite difficult to get rid of, and the air in the rooms is filled with its toxic fumes.
Waterproofing with films
Such consequences can be avoided during construction. To do this, following the technology, you must correctly perform the following processes:
- Surface preparation;
- Installation of a vapor barrier film, as well as a ventilation gap;
- Laying insulation;
- Film waterproofing installations;
- Facade cladding.
To protect walls from moisture, a special film is used, which is a three-layer material. The main and central layer is a polyethylene reinforcing mesh, covered on both sides with polyethylene film lamination.
Its direct purpose is high-quality thermal insulation protection, as well as wooden structure from the destructive effects of moisture. Waterproofing is the second barrier (after the façade covering) that prevents precipitation from entering the structure.
Moisture-proof films are ideal for wooden houses, because they:
- safe for health;
- not susceptible to rotting or fungal infection;
- prevent the formation of mold;
- do not emit toxic fumes;
- resistant to UV radiation;
- durable;
- help retain heat.
The cost of such films is relatively low, but they are significantly superior to outdated, ineffective materials.
Installing waterproofing when insulating walls
Homes from natural materials are quite beautiful, so the outer parts of the walls are usually left untouched. However, many owners are increasingly insulating their houses from the street side, decorating the walls with functional finishing materials. Modern technologies, as well as an extensive selection of materials allow you to create high-quality ventilation system such facades, as well as extend the life of houses.
To perform insulation and, in particular, waterproofing the walls of a wooden house with your own hands, you will need:
- special emulsion to protect against mold and/or mildew;
- aluminum self-adhesive tape for insulation work;
- required amount mineral wool;
- vapor barrier film;
- construction stapler;
- hammer;
- timber for sheathing with a section of 40×100;
- scissors or construction knife;
- nails;
- jute tow;
- thin slats;
- dowels;
- construction level;
- self-tapping screws;
- waterproofing film;
- screwdriver, drill or hammer drill.
Work order:
- The walls are cleaned and treated with a special emulsion or several compounds, allowing each layer to dry thoroughly. An antiseptic is applied to the bars and slats.
- Treat cracks, cracks, gaps with tow, compacting the material well.
- Using slats, a hammer and nails, mount vertical sheathing in increments of 100 mm.
- Attach the pre-cut vapor barrier sheets to the sheathing with a stapler, laying the material with the glossy side facing you (the porous side is directed towards the wall). Pay attention to creating a gap for ventilation: leave 20 mm holes between the slats. up and down. Carefully seal all joints with special tape.
- Installation of sheathing. The beams (located with an edge to the wall surface) are nailed or screwed with self-tapping screws, always using a level. The pitch of the lathing depends on the width of the mineral wool slabs - so that it is convenient to lay it. It is important to use solid timber, because the facade frame will be installed on it.
- Laying thermal insulation in a “checkerboard” pattern with complete exclusion of gaps.
- Installation waterproofing film. Mandatory condition: the overlap of the canvases is 100-150 mm. The canvases are carefully stapled to the sheathing. The joints are sealed with special tape.
- Ventilation gap made using lathing with a 25×50 lath. A protective metal mesh is installed below.
- Installation finishing material according to the instructions.
