Waterproofing a bathroom in a wooden house - from A to Z. Methods for waterproofing a bathroom located in a wooden house Waterproofing a bathroom in a private house

Being one of the oldest materials used to build buildings, wood still does not give up its position. A wooden house is beautiful, comfortable, environmentally friendly. At the same time, one should not forget about, perhaps, the only drawback of this material - susceptibility to moisture. Of course, this does not mean that you need to forget about hygiene.

Installing a full-fledged bath or putting a shower in a wooden house is realistic, but this will require reliable protection of the floor from water and high-quality waterproofing wooden walls In bathroom. Modern materials make it easy to cope with this task.

Waterproofing zones

The location of the bathroom must be determined at the design stage. Allocate a place for a bath, if necessary, strengthen the overlap under it, lay pipelines for cold and hot water think about drainage. If we are talking about a two-story building, then it seems correct to install a bathroom on the lower floor. On the top, you can equip another room of the same purpose, but limit it to a shower, sink and bathroom.

Advice! To protect yourself from a possible accident caused by water overflow, it is worth lowering the bathroom floor by at least 10 cm relative to the general level.

Thanks to this little trick, it will be possible not only to avoid large-scale flooding, but also to save yourself from the need to strengthen waterproofing throughout the house. In general, the floor of a bathroom in a house built of wood will include a base, a layer of rolled waterproofing, cement screed and topcoat.

Waterproofing in the bathroom of a wooden house is laid not only on the floor. It is required to protect the entire room, this applies to walls and even the ceiling. It is important to protect the wood as much as possible from the penetration of moisture, thereby preventing mold and decay. In the course of work Special attention given to the so-called wet areas of the room. These include:

• the floor as a whole and at least 10 cm of the lower part of the walls;
• walls above the bath or near the shower;
• place of installation of the sink and bathroom;
• walls near the washing machine.

To ensure maximum protection against moisture, additional insulation is laid on the walls at the plumbing installation sites, blocking the possible splash zone, as a rule, it is 0.5 meters in each direction.

waterproofing material

Long gone are the days when only the “classic” roofing material came to mind when the word waterproofing came to mind. Modern industry offers a number of materials that differ in their characteristics, installation method and price.

sheet material

The features of this material are clear from the name - these are rolls or sheets, which are polymer, fiberglass or paper base impregnated with special compounds. The canvases are overlapped on the base, the joints are glued using mastic compounds. Next, the finished surface is heated, achieving adhesion of the insulation to the base.

Such material can cover not only the floor, but also the walls. At correct styling the surface is reliable and durable. It is worth noting that laying such insulation is a laborious process, experience is needed for a good result, it is better to entrust the work to specialists. This is a significant disadvantage, as is the high price of the material.

Painting with mastic

Enough in a simple way creating waterproofing floors and walls is a painting method. To obtain a coating that is resistant to excessive moisture, mastic is used. Its consistency is similar to that of ordinary paint, so the methods of working with it are similar.

Note! Using mastic is simple, it does not require special knowledge and equipment to apply it, in most cases a simple paint roller and brush are enough.

Mastic is equally well applied to the floor and walls. To get a high-quality coating, you need at least three layers, between applying each of them the wall is allowed to dry for 3-4 days. After hardening of the last layer, a surface with excellent water-repellent properties is obtained. The only thing that can be written down in the cons of this type of waterproofing is a short service life. The coating will last no more than 5 years.

Coating waterproofing

Another simple and effective waterproofing option. According to the method of application, it resembles mastic, but differs in composition. This material is sold in dry form, diluted with water before use. The application method is completely identical - a roller or brush is used. It is easier and faster to work with a roller, the corners are smeared with a brush.

As a rule, two layers are applied. The first is allowed to harden for 5-6 hours. The second is applied with movements directed perpendicular to the first layer. Leave until completely dry. As a result, the surface of the floor or wall will be covered with a film that has good water-repellent properties. In addition to ease of operation, this method characterized by a sufficiently long service life.

Wall and ceiling waterproofing

In the bathroom of a wooden house, the waterproofing of the walls and ceiling is given no less attention than the treatment of the floor. Moisture protection is required not only in places subject to water ingress, but also in areas relatively remote from its sources. Do not forget that the bathroom gives off steam, which will certainly condense on any surface.

To reduce the amount of condensate, it is recommended to choose a room for the bathroom that is surrounded by other rooms, where no wall is a side wall of the building. If this is unrealistic, then it is necessary to ensure maximum thermal insulation of the outer walls.

Before laying the waterproofing, it is necessary to complete the installation of water supply and sewage pipes. Wooden walls and ceiling are sheathed with rolled waterproof material.

Work begins with cleaning the surface, it must be dry and clean. The ceiling and walls are covered with a primer. Next, sheets of waterproofing material are overlapped, the joints are fixed with construction tape, and the coating is allowed to dry.

Instead of roll materials, you can use special moisture-resistant mastics for wood. They are easy to work with, they do not require a preliminary primer, you just need to apply an even layer of the composition and let it dry.

After a few days you can go to interior decoration. The choice of material depends entirely on the wishes of the owners. You can use lining, you can use familiar tiles, the interior looks great, in which wood and tiles complement each other.

Wood floor protection

Quite often the owners wooden houses prefer to withstand all the premises in the "wooden" style. They make a wooden floor, the walls are sheathed with clapboard. It is beautiful and functional, but it is important to understand that the durability of such an interior largely depends on the quality of the work done to protect the house from moisture.

Waterproofing the wooden floor in the bathroom is best done double. The first layer is laid at the transition between the ground (floor) and the subfloor, the second serves as the base for the top coat. In this case the best choice for the bottom layer of waterproofing there will be reinforced polyethylene or other roll coating with great strength. The film is overlapped, the joints are additionally glued with adhesive tape.

If the logs are installed on subfloor boards or interfloor overlap, instead of roll material, it is advisable to use bitumen-based mastic. It will not only retain water, but will also be absorbed into the wood, providing it with maximum durability. In any case, the insulating material must extend at least 10 cm into the wall.

Next, the foundation is laid for the future flooring. For a wooden floor, it is rational to choose an easy option. Its peculiarity lies in the fact that the space between the lags is filled heat-insulating material, on top of which a vapor barrier film is laid. In this case, one must not forget to leave a gap of about 30 mm between the film and the insulation.

The basis of the future coating will be OSB boards or multilayer plywood. It is important to choose a waterproof material. Some recommend making a base of two layers of slab, laying the material with overlapping joints. This method provides good protection from moisture, while you do not have to buy obviously more expensive thick wood board.

The surface of the plates is treated with mastic, special attention is paid to the joints. After it has absorbed and dried, you can lay the floor covering.

Floor waterproofing under tiles

A good option for finishing the floor in the bathroom is the usual tile. She is not at all afraid of water, has an attractive appearance, in addition, there are a huge variety of types and colors for sale for every taste. But the waterproofing of the bathroom in wooden house made under the tile, there are features.

Preparation of the base and the bottom layer of waterproofing

For tiles, it is better to choose a heavy version of the floor. In this case, a concrete screed is used as an equalizer.

A heavy floor has a number of significant advantages:

• low price compared to wood-based flooring;
• high density and reliability, excluding deflections under the tile;
• the possibility of using simple and cheap methods of waterproofing;
• savings on floor height.

Of course, the use concrete screed does not exempt from the need to create a lower layer of waterproofing. It is laid in exactly the same way as when creating a light wood-based floor. In general, the process of creating a concrete floor can be thought of as a series of actions.

First, the waterproofing material is laid, then the necessary communications are installed, the reinforcing mesh is installed and the concrete is poured.

To protect yourself from cracks and irregularities, it is recommended to use ready-made dry mixes with a plasticizer. Prepare a solution, pour. Let the floor dry before starting the next work.

Basic waterproofing

Since the bathroom is a room with almost 100% humidity, the highest demands are placed on the main inner layer of floor waterproofing. It must withstand not only high humidity and steam, but also real puddles.

The choice of waterproofing method directly depends on the subsequent coating, if for a board or laminate the best option rolled material is seen, then for tiles advantage should be given to mastic. Apply at least two layers. The corners are additionally glued with a special tape, on top of which mastic is also applied.

The last layer is allowed to dry. The hardening time of a particular composition is indicated in the instructions and can range from several hours to several days. After that, it remains only to lay the tiles, decorate the walls, ceiling, install plumbing and you can use the bathroom.

Properly executed waterproofing will help to “make friends” with wood and moisture. With very little effort, own house there will be a corner of comfort - a bathroom. It's really easy, and if most of the work is done by hand, then it's inexpensive.

Wood is one of the most environmentally friendly and safe building materials. Wooden houses began to be built many centuries ago, and today wood is widely used in the construction country houses, dachas, cottages, outbuildings. Compared to other materials for building construction, wood is more demanding in terms of care and has a shorter service life. One of the worst enemies of a wooden house is moisture. Exposure to moisture can cause fungus and mold to develop, destroying wood and causing it to rot. In addition to the destructive effect on wood, fungus and mold adversely affect human health, releasing toxins and toxic compounds. Living in such a room becomes hazardous to health, and children and those who are prone to manifestations of various types of allergies are the first to suffer. Therefore, waterproofing wooden walls is a top priority when building a house. The insulating coating will protect the wooden house from high humidity and prevent the occurrence of mold and fungus.

In ancient times, no special methods were used to protect wooden walls from moisture. The builders cut the ends of the logs with an ax, thereby sealing the pores of the wood, and the cracks and crevices were simply sealed with moss. Today there are various ways waterproofing, and many special protective products are available to protect wooden buildings from exposure environment and thereby significantly increase their service life, maintain performance and appearance.

What is the waterproofing of the walls of a wooden house

When erecting wooden buildings, it uses several various kinds waterproofing, including:

• coating or its variety - painting;
• pasting;
• asphalt;
• hard.

Coating waterproofing of wooden walls is made using mortars using bitumen or emulsion as a base and containing special fillers and additives. Such a coating is applied to the inner or outer surface of the walls in a single layer with a thickness of about 5 mm. Its variety, paint waterproofing, is produced using special liquid or plastic compositions applied sequentially in three layers, the coating thickness is 0.5-0.7 mm. When choosing this type of insulation, it should be borne in mind that coating and painting waterproofing protect the surface of wooden walls only from the penetration of capillary moisture, that is, they cope with their protective function in the absence of hydrostatic pressure.

Pasting waterproofing is made using roll materials, which are mounted using mastic. Most often, isol, roofing material, hydroisol, etc. are used as pasting insulating materials. The material is fixed using hot and cold mastics. Before applying a layer of mastic to the surface, experts advise applying a layer of primer. Most often, the surface is pasted over from the hydrostatic head. The waterproofing material can be laid in several layers, depending on the strength of the hydrostatic head and the humidity category.

Pasting waterproofing is carried out using rolled insulating materials

Asphalt waterproofing is produced by laying a solid layer of asphalt mass with a layer thickness of up to one and a half centimeters. Such a coating can be applied both on horizontal and on inclined surfaces in the basements of wooden houses. Asphalt waterproofing is available in two varieties: hot and cold. Hot mastics are more durable, but their cost is significantly higher than that of cold ones. The waterproofing properties of hot asphalt appear after it cools, and for cold asphalt - after it dries.

The most time-consuming way to protect a wooden house from moisture is rigid waterproofing. The protective coating is carried out in the form of a layer of plaster, consisting of cement and sand, which is applied first to the walls and floor of the basement, and then to the floor in the house itself. For such insulation, it is best to choose a waterproof cement that does not shrink. In addition, Portland cement, which includes sealants, is often used in waterproofing work. Rigid waterproofing is the most reliable protection against moisture for wooden buildings.

All these waterproofing methods are used both for floors and walls in a wooden house. High-quality waterproofing will protect the wooden structure from the damaging effects of moisture, the occurrence of fungus and mold and will significantly extend the life of the house. It should be borne in mind that along with the external waterproofing of a wooden building, care must be taken to protect the internal space from moisture. Internal waterproofing of wooden walls is carried out by treating their surface with special sealants. When treating the wall surface with such a waterproof sealant, special attention should be paid to the seams and joints of the logs.

Waterproofing with plaster will reliably protect the walls of the building from moisture

When choosing the type of waterproofing coating for wooden walls, first of all, they pay attention to what kind of exterior and interior cosmetic finishes the house will have. If you plan to preserve the natural look of wood as much as possible, the best choice there will be paint waterproofing. The adhesive insulation needs additional protection from the outside before finishing work on the building.

Creating a moisture barrier in the bathroom of a wooden house

As you know, fungus and mold very often appear in the bathroom. Since the level of humidity in the bathroom is constantly elevated, additional waterproofing measures are required in the bathroom.

Equipping a bathroom in a wooden house, you need to consider the following points:

• prerequisite is the preliminary waterproofing of the walls;
• to protect the surface of the walls from exposure to a high concentration of moisture in combination with high air temperature, it is recommended to use special vapor-proof films.

The surface of the walls is pre-plastered with special mixtures and treated with fungicidal and antibacterial protective compounds. After that, putty is applied to the walls and a fine finish is made. Instead of vapor barrier films, bituminous roll insulation materials can also be used.

What to pay attention to when carrying out waterproofing work

Waterproofing the walls of a wooden house is a complex process that requires an integrated approach. In order for the building to be reliably protected from moisture, it is important that both external and internal waterproofing of its walls and ventilation of the facade system be carried out. The latter condition is especially relevant in the construction of log houses.

Waterproofing the walls of a wooden house will help extend the life of the building for many years.

In houses made of rounded logs, most often additional facade decoration is not performed. In buildings made of profiled timber, after the final shrinkage of the log house, as a rule, a facade system is installed, where as finishing materials use:

• siding and corrugated board;
• decorative wall stone and brick;
• plaster facade mixtures;
• eurolining.

When installing a facade finish, it should be borne in mind that the wooden part of the wall structure must have access to air, the wood must “breathe”.

In addition to waterproofing wall structures, wooden buildings also require protection against ground water. If the building does not have a basement, it is possible to install a protective inter-foundation layer of roofing felt or roofing felt. If the house has a basement, the inter-foundation layer will not be able to reliably protect the building from groundwater. In this case, when laying the foundation concrete blocks coated with a special waterproof compound.

Waterproofing wooden walls is very important to protect the building from moisture.

Waterproofing the walls of a wooden house is a complex labor-intensive process. In order for the building to be reliably protected from the destructive effects of moisture, fungus and mold did not appear in the house, and its walls did not lose their strength for a long time. performance characteristics, it is necessary that waterproofing work be carried out competently and professionally, taking into account all design features building. Only in the case of waterproofing by professional experienced builders, you can be sure that your house will serve for many years, and life in it will be cozy, comfortable and safe for health.

The level of planning and arrangement of a bathroom in a frame or log house allows you to judge how comfortable a long stay in such a room is. Often the bathroom and bathroom are the most problematic areas. wooden building. To protect the support beams, logs, floorboards, which are at the greatest risk of wetting and rotting, you will need a fairly effective waterproofing of the wooden floor in the bathroom. In conditions where the possibilities of the ventilation and heating system are not enough, or the room is located on the basement floor, with an intensive influx of moisture from the ground, a complete waterproofing of the bathroom in a wooden house will be needed.

Materials for arranging waterproofing

For each specific building, with its own architecture and layout, experts select the optimal scheme for waterproofing a bathroom in a wooden house. There is no universal recipe, therefore, to build effective protection, several types of insulating materials have been developed, each of which has its own advantages and disadvantages:

• Bituminous and mastic coating compositions. Waterproofing is carried out by applying a viscous bituminous mastic to all the main elements wooden structures. After drying, a dense elastic layer of bitumen modified with butyl-styrene copolymer is formed;
• Painting materials of deep impregnation, most often on an organic basis. They are applied with a spray gun or a brush on the surface of wooden structures of the floor and walls of the building. Give the tree water-repellent properties and at the same time protect against pathogenic microflora and insects;
• Roll materials based on fiberglass and bitumen. It is used only as an intermediate waterproofing on a concrete or panel surface;
• Elastic membranes based on polyurethanes and polyureas. According to sanitary standards, such a coating can be used as a waterproofing of any interior of a wooden house.

For your information! In addition to the above, in the list for waterproofing, self-leveling floors on an epoxy or polyurethane basis can be used. Acrylic or cement-containing materials for waterproofing wooden structures are practically not used.

Separately, it is worth mentioning several natural options for waterproofing: betonite clay, asphalt and tar mixtures, pressed powder rubber, gum resin, tar and much more, which is often presented by environmentalists as environmentally friendly materials. The logic of sellers of such recipes is extremely simple - for an environmentally friendly wooden house, waterproofing must also be environmentally friendly.

In fact, all of the listed materials for "natural" floor waterproofing not only pose a certain danger due to the high content of carcinogens, but are also extremely short-lived. If desired, clay of special grades or liquid glass can be used to protect a stone cold floor on a soil basis, to waterproof a wooden floor in a bathroom from groundwater and moisture, but not for internal protection from exposure to a humid atmosphere.

Technology for arranging waterproofing inside the bathroom

The use of modern materials allows you to get very high level waterproofing wooden walls and floors even in conditions of almost 100% humidity and with a water film on the flooring. Any form of waterproofing is almost never a top coat, especially when it comes to a bathroom in a wooden house.

The process of arranging waterproofing consists of four stages:

1. Arrangement of ground insulation;
2. Repair and restoration of load-bearing structures of a wooden floor;
3. Laying the first layer of waterproofing, lining the walls of the bathroom with drywall or OSB boards;
4. Casting a concrete screed or self-leveling floor - leveler;
5. Application of final waterproofing;
6. Laying ceramic tiles on an elastic tile adhesive, sealing joints and baseboards with epoxy grout.

For your information! For the bathrooms of a wooden house, the golden rule must be followed - waterproofing must be double and it is imperative to protect the floor both from the inside of the room and from the back.

The exception is the bathrooms, equipped on the second floors of wooden houses. In this case, the floor base is made of pressed boards, lumber bags or waterproof drywall sheets. Final waterproofing is applied to the primed wooden surface walls and floors, after which you can glue the tiles.

The first stage of arranging waterproofing a bathroom with a wooden floor

The favorite location of the bathroom in a log or log house is the corner room on the ground floor. In this layout option in a wooden house, it is easier to organize the drainage of wastewater and the supply of hot water. If the house is built of timber or logs, the bathroom space will have to be seriously re-equipped. This is not only about the need for a radical alteration of floors and waterproofing, it will be necessary to treat the timber walls with hydrophobic impregnation like Tikkurila, lay film waterproofing, insulation and perform wall cladding with plasterboard sheets.

Waterproofing a wooden floor in a tiled bathroom begins with the laying of internal insulation and insulating materials. To do this, the floorboards are removed, part of the soil is removed for laying a layer of sand, thick polyethylene film and a layer of insulation.

If there is a basement under the bathroom, the floor can be waterproofed using rolled roofing materials. An additional concrete screed and surface treatment with a primer are pre-expelled. Traditionally, roofing material is laid on concrete by welding, but in a wooden house, molten mastic is usually used to waterproof the floor in a room. All wooden parts of the floor base, including logs and floor beams, are treated with coated waterproofing or roofing mastic.

After sticking the polystyrene foam insulation, the floor surface is filled with a layer of leveling agent, the only way to perfectly level the plane for laying tiles. If desired, drywall or OSB boards can be laid. If the bathroom is located on the second or third floors, then the final waterproofing can be applied to a wooden floor cleaned of paint and dirt.

Stage two, applying the final waterproofing

The highest quality waterproofing coating that provides reliable protection for wooden walls and floors can be obtained using HIDROFLEX sealant paste. trademark Litokol or similar polyurea resins. The material is a thick, viscous, odorless, non-toxic mass that does not require hardeners or polymerizers. The paste can be applied to the prepared surface with a roller or wide spatula.

Properly selected primer ensures strong adhesion of the elastic waterproofing layer, with a thickness of 1 to 5 mm, with concrete, plasterboard, wooden base. Depending on the air temperature, the material dries from 10 to 20 hours.

The concrete floor screed and plasterboard slabs of the bathroom walls are pre-coated with a primer. When choosing a primer brand, you need to be careful, since not all primer mixtures are suitable and interchangeable for waterproofing materials from different manufacturers. Paste can be applied already 40 minutes after priming. Previously, an elastic tape is glued to the paste at the corners and joints of the walls with the floor. Separately, all the conclusions of communications and sewerage are pasted over, any ledges and bends of the walls are glued with tape at the overlap joints.

After sticking the tapes, you can proceed to waterproofing the walls and floor of the bathroom. The material is applied at a temperature of 5 to 40 ° C, after drying, the elastic coating retains its insulating properties from minus 20 ° C to 170 ° C. This means that the tiles glued to the finish layer in the bathroom of an unheated cottage will not fall off even in winter.

Mass consumption is 1.3-1.5 kg/m 2 . The paste is applied in two layers, initially a layer of 1-2 mm is rolled onto the walls of the bathroom with a roller, then the floor is covered. After the first layer has dried, a second layer of material is applied. After applying two layers, the thickness of the waterproofing is 3-4 mm, which is more than enough for a bathroom and even a mini-pool.

The waterproofing layer of the floor in the bathroom of a wooden frame house remains elastic throughout its entire service life, but it cannot be used as a final coating; when walking, the layer quickly wears out and peels off from the base.

25-30 hours after applying the paste, you can start sticking ceramic tiles. To lay the flooring on the surface of HIDROFLEX type paste, it is necessary to use elastic tile adhesive grades, ordinary cement or gypsum mortar will be unnecessarily hard.

Conclusion

Tile joints and corner joints must be grouted epoxy resin. The main advantage of using polyurea resins for waterproofing is their high elasticity and strength. A wooden house shrinks and “breathes” within 3-5 years from the moment of construction, therefore, it is possible to ensure reliable insulation at “playing” joints and seams only in this way.

Modern wooden houses are characterized by increased comfort and convenience. They are equipped with bathrooms and bathrooms with a good ventilation system and heated floors. Arranging a bathroom floor in a wooden house is a little more difficult than making it in a building made of concrete, brick or foam blocks. The main task is to protect it well from moisture. If the design is made in compliance with the technology, then it will be durable, strong and warm. We will tell you how to make a bathroom floor in a wooden house.

Wooden flooring in the bathroom

The floor in the bathroom wooden beams sometimes requires a concrete screed device. So that the surface after the screed device does not rise much above the floor level throughout the house, the beams should be laid slightly lower in this room. To insulate this surface in a wooden house, heat-insulating material is placed in the gap between the beams.

To increase the reliability of the floor, it is necessary to make a drain sewer ladder. It is connected to the general sewer system. Thanks to the ladder, accidentally trapped water is removed from the surface. When installing a screed in this room, make it slope towards the ladder. A slope of 1.5% is usually sufficient.

Important! So that there are no problems with the wooden floor in the future, only whole high-quality sewer pipes. Plastic sewer systems are reliably protected from leaks.

If the wooden floor in the bathroom is not made according to the screed, then they are laid on the logs:

• cement particle boards;
• moisture resistant plywood in two layers;
• flat slate is also suitable for these purposes.

Bathroom floor waterproofing

If you make wooden floors in the bathroom with your own hands, then it is important to arrange high-quality waterproofing. The waterproofing layer will reliably protect the beams from moisture, decay and damage by microorganisms. It is also necessary to isolate the lower part of the walls from moisture. Usually they are covered with insulating material from below to a height of at least 200 mm.

If you do not know how to waterproof a wooden floor in a bathroom, then one of two types of insulating materials is used for this:

• adhesive insulation;
• coating insulating materials.

These insulators protect the wooden floor in the bathroom equally well from moisture. The differences between them are only in the method of application. Let's consider their features in more detail.

Waterproofing materials

To perform surface sealing using roll materials, apply:

• roofing material and roofing felt (they are the cheapest and short-lived);
• isoplast;
• ecoflex;
• mostoplast;
• isoelast.

Important! Roll-type insulation is longer and more difficult to lay, but further work begins immediately after laying.

They are laid in the following sequence:

1. The preparatory work consists in the fact that the base must be leveled, dried well and primed.
2. There are several ways to lay insulating materials:

• on adhesive composition the usual roll material is laid;
• no adhesive layer is needed when using self-adhesive insulators. In this case, before laying, the protective coating is removed from the back of the product, and the material is tightly glued to the base;
• it is also possible to cover the base in this room with the help of built-up insulating coatings. In this case, bonding occurs under the influence of high temperatures. A gas burner is used to heat the material;
• there is still floating waterproofing, but its laying is quite complicated and requires certain knowledge and skills.

Attention! Rolled materials are laid with an overlap of strips by 100 mm. The coating must be welded onto the lower part of the walls or attached to them using a construction stapler.

The easiest way is to waterproof the floor in the bathroom in a wooden house with your own hands using coating materials. For this, bitumen-based mastics are used without bad smell. These materials are resistant to aggressive impact and elevated temperatures. They adhere well to the base.

Instructions for the use of coating waterproofing differ depending on the type of material:

1. If you decide to surface bituminous composition, then know that there are products for cold and hot application. Hot coatings are heated to 160 degrees before laying, so certain skills are required to work. Cold compounds are easier to install, but they should not come into contact with concrete base.
2. Bitumen-polymer insulating materials contain latex fillers, organic solvents and plasticizers. Suitable for laying on any substrate without preheating. The result is a very strong and durable insulating layer.
3. Polymer-cement compositions adhere well to the concrete base, because they contain cement in their composition. The result is a stable and flexible protective layer.
4. Acrylic waterproofing mixtures produced on the basis of water. These aqueous emulsions are odorless and environmentally friendly. Acrylic compositions give plastic and durable coating but cost a lot.

Advice! To improve the quality and reliability of the waterproofing layer, coating compositions are applied in 2 layers.

The choice of finishing material

Most often, the floor in the bathroom in a wooden house is made of ceramic tiles. This material is distinguished by an acceptable price, attractiveness, unpretentiousness in care, strength and wear resistance. Ceramic tiles used in underfloor heating systems. Moreover, it is easy to choose an option with imitation wood, which will harmoniously fit into a wooden house. The tile is laid only on an inactive concrete base.

If you want to know how to cover the wooden floor in the bathroom, in addition to tiles, then the following materials are suitable for this purpose:

• laminate;
• linoleum;
• massive board.

Consider the features of each coverage.

Linoleum

This a budget option bathroom covers. Linoleum is characterized by low flammability, durability and resistance to moisture. The most wear-resistant linoleum belongs to commercial grades. For a bathroom house made of wood, a material with imitation of a plank floor is more suitable.

Linoleum is laid directly on the waterproofing layer. If the area of ​​\u200b\u200bthe room is very large, then the joints of the strips of material must be spliced ​​using the hot method in order to reliably protect the base from moisture.

Laminate

A laminate that accurately imitates a wood surface will successfully fit into the interior of a wooden house. It is better to purchase high-quality, wear-resistant products. They are more expensive, but also more durable.

Important! For the bathroom, only a moisture-resistant laminate with increased wear resistance is suitable.

Tree

Few owners of such houses dare to make wooden flooring in the bathroom. This is explained by fears that the wood will rot, mold and deteriorate from getting wet. Moreover, with changes in temperature and humidity in the room, many wooden surfaces are subject to deformation. However, if you know what type of wood to use for such premises, then many problems can be avoided.

Important! For the floor in the bathroom, only teak and larch wood is suitable.

Since teak contains a lot of oils, the wood is resistant to moisture. Teak has been used in shipbuilding since ancient times. To seal the gaps between the boards, a special ship sealant is used. Because of high cost materials this type of finish is rarely used. Larch is not as expensive as teak, so it is more popular.

A bathroom in a wooden house is usually referred to as the so-called "problem" places that give its owners a lot of trouble. And, indeed, the high humidity of this ancillary space has a damaging effect on adjacent rooms, making them unsuitable for permanent habitation. That is why reliable waterproofing of a bathroom in a wooden house is a prerequisite for creating normal conditions for living in it.

The complexity of protecting individual elements of wooden structures from moisture is due to the fact that the use of traditional waterproofing materials (roofing material, 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 questions on the organization of waterproofing of such a bathroom are solved quite simply. In the article we will consider ways that will not only help to perform high-quality waterproofing, but also transform the look 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 their gluing on a wooden surface, a special heated mastic is used);
• liquid compositions based on cement (hot bitumen, pitch);
• special impregnating coatings made of water-repellent cement with the addition of chemicals and crushed sand.

The basis for applying waterproof liquid compositions is pre-laid sheet or roll-type waterproofing with a layer of reinforced glass fabric laid on top of it. This combination of protective materials forms an ideal seamless coating that meets all the requirements for waterproofing.

Impregnating materials after application to the surface of the wood penetrate into the top layer of the latter and make it waterproof.

This type of waterproofing is very rarely used in residential areas.

We also note that when organizing work on insulating the bathroom in a wooden house, separate waterproofing of the floor, its walls and ceiling is assumed. Let's consider the order of carrying out each of these operations in more detail.

Floor waterproofing

Do-it-yourself floor insulation in the bathroom is the most time-consuming of the procedures included in the complex of waterproofing works organized in a private house. But at the same time, you can always use the option of waterproofing, the implementation of which will be quite cheap and simple.

The order of work performed with the above choice, as a rule, is presented in the following form:

• first on wood flooring, previously cleaned of foreign objects and small debris, a whole piece of PVC film (or the thinnest linoleum) is laid as a waterproofing, the edges of which are folded with an overlap on the walls by about 15–20 cm;
• in order to level the laying plane at the corners, the material is cut and then filled with silicone sealant. For reliability, the edges of linoleum are fixed on the walls with a liquid bituminous composition or mastic;
• after that, reinforcement is laid on the linoleum in the form of a fine mesh, along which the usual one is then made.

According to this method, it can also be made from known rolled materials containing bitumen at its core (from roofing material, for example, or using a built-up roof). But this approach will be more costly, especially if you use as a basis modern materials high cost.

When using roofing felt, the surface of the 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. sheets. In this case, the blanks used are stacked in several layers so that each of them is perpendicular to the previous one.

In this case, as well 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 the bathroom in a wooden house, as a rule, are laid out either from round logs (round logs) or from ordinary timber. At frame structure buildings they can be trimmed edged board or OSB boards, for example. In all cases, except for the last one, special preparation of the walls is required, which boils down to leveling them for the purpose of subsequent laying on the surface or PVC panels.

Before doing this part preparatory work, first of all, you will need to prepare a special frame for. Waterproofing measures in this case are reduced to the use of a special moisture- and vapor-tight film laid between drywall sheets and a wooden wall.

When decorating walls with OSB boards special training to apply a layer of waterproofing is not required. In this case, the paint method of forming a protective layer is most often used with preliminary preparation of the wall surface by sealing the seams formed on the surface. In this case, the sealant used and the waterproofing material itself should, if possible, belong 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 it will be possible to lay the finishing material of your choice.

TO protective treatment shower walls in a wooden house, it is advisable to proceed only after the completion of the waterproofing of its floor.

ceiling insulation

The technique of waterproofing the ceiling in the bathroom is not much different from the methods already described and also depends on the class of material used in its arrangement. So, it will be enough to apply a special water-repellent impregnation to the ceiling from an ordinary lining; at the same time, a vapor-tight film should be placed under the frame used for sheathing. For any other option for finishing the ceiling, you can use mastic or a special impregnation used to protect the bases 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, leading 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 also differ.
