On the issue of waterproofing a bathroom in wooden house must be approached with special talent and mathematical mind. 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, or be destroyed by fungus. To protect wood from exposure to moist air, steam and water in the bathroom, while maintaining the original appearance of 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 outer wall for withdrawal ventilation shaft or pipes.
• 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 coniferous trees: pine, spruce and larch, the resins of which, when heated by 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. These are elastic waterproofing coatings consisting of two components: a powder of inert fillers and anti-water binders, as well as an aqueous dispersion acrylic polymers. Best performance hydrophobicity is shown by rubber-bitumen mastic. It remains constant after freezing even when the geometry of the building structure is deformed.

As with adhesives, additional strength coating waterproofing reinforced with fiberglass mesh. 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 a reinforced screed is arranged, 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, it is necessary to perform a screed under small 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 good option for decorating a hygienic room. Wall panels made of MDF – Medium Density Fiberboard – have become very popular in Russia. 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 cash on finishing the bathroom and toilet. Due to the lack of a thermal insulation layer, this advice is not suitable for all owners of 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. If we're talking about Regarding 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 love hot water and long-term water treatments.

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 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 installing decorative materials. The most important stage, without which acceptance water procedures may be hazardous 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 supply ventilation valve. 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 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.

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 to maintain and has a shorter service life. One of the most worst enemies wooden house - moisture. Exposure to moisture can cause the appearance of fungus and mold, which destroy the wood and lead to its rotting. In addition to their destructive effects on wood, fungus and mold have a detrimental effect on human health by releasing toxins and toxic compounds. Living in such a room becomes hazardous to health, and children and those who are prone to various types of allergies are the first to suffer. Therefore waterproofing wooden walls- the first priority when building a house. An insulating coating will protect a wooden house from high humidity and prevent the occurrence of mold and mildew.

In ancient times, no special methods no protection was used for wooden walls from moisture. The builders trimmed the ends of the logs with an ax, thereby sealing the pores of the wood, and simply sealed the cracks and crevices with moss. Today there are various ways waterproofing, and many special protective equipment allowing to protect wooden buildings from environmental influences and thereby significantly increase their service life, maintain performance characteristics and appearance.

What types of waterproofing are there for the walls of a wooden house?

During construction wooden buildings uses several different types of waterproofing, including:

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

Coating waterproofing of wooden walls is carried out using mortars, using bitumen or emulsions as a base and containing special fillers and additives. This coating is applied to the internal or outer surface walls in a single layer about 5 mm thick. Its variety, paint-based waterproofing, is produced using special liquid or plastic compounds applied sequentially in three layers, the coating thickness is 0.5-0.7 mm. When choosing this type of insulation, you should keep 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.

Pasted waterproofing is made using rolled materials, which are mounted using mastic. Most often, Isol, roofing felt, hydroisol, etc. are used as lining 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 glued on the hydrostatic pressure side. Waterproofing material can be laid in several layers, depending on the strength of the hydrostatic pressure and the humidity category.

Pasted waterproofing is carried out using rolled insulating materials

Asphalt waterproofing is produced by laying a single layer of asphalt mass with a layer thickness of up to one and a half centimeters. This coating can be applied to both horizontal and 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 cold ones. The waterproofing properties of hot asphalt appear after it cools, and of cold asphalt - after it dries.

The most labor-intensive way to protect a wooden house from moisture is rigid waterproofing. Protective covering performed in the form of a layer of plaster consisting of cement and sand, which is first applied to the walls and floor basement, and then on the floor in the house itself. For such insulation, it is best to choose waterproof cement that does not shrink. In addition, quite often in waterproofing works They use Portland cement, which contains sealants. Rigid waterproofing is the most reliable protection against moisture for wooden buildings.

All these waterproofing methods are used for both floors and walls in a wooden house. High-quality waterproofing will protect a wooden structure from the destructive effects of moisture, mildew 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, it is also necessary to take care of protection from moisture internal space. Internal waterproofing of wooden walls is carried out by treating their surface with special sealants. By treating the wall surface with such a waterproof sealant, Special attention should be given to seams and joints of 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, pay attention to what kind of external and internal cosmetic finishing the house will have. If you plan to preserve the natural appearance of the tree as much as possible, optimal choice There will be paint waterproofing. Pasting insulation needs additional protection outside before finishing work on the building.

Creating a moisture-proof layer in the bathroom of a wooden house

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

When arranging a bathroom in a wooden house, you need to consider following points:

• prerequisite is to carry out preliminary waterproofing of walls;
• To protect the wall surface from exposure to high concentrations of moisture combined with high air temperatures, 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 this, putty is applied to the walls and finishing. Instead of vapor barrier films, bitumen 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 and requires an integrated approach. In order for a 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 are carried out. The last condition is especially important when constructing timber 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, additional facade finishing is most often not performed. In buildings made of profiled timber, after the final shrinkage of the frame occurs, as a rule, they install facade system, where as finishing materials use:

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

When installing facade finishing It should be taken into account 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 from groundwater. 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 interfoundation layer will not be able to reliably protect the structure from the effects of groundwater. In this case, when laying the foundation, the concrete blocks are coated with a special waterproof compound.

Waterproofing wooden walls is very important to protect the structure 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 do not appear in the house, and its walls do not lose their properties for a long time. performance characteristics, it is necessary that waterproofing work be carried out competently and professionally, taking into account all the design features of the building. Only if waterproofing is carried out by professional, experienced builders can you be sure that your home will serve for many years, and life in it will be cozy, comfortable and safe for health.

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 a bathroom in a wooden house is a prerequisite for creating normal living conditions in it.

The difficulty of protecting individual elements of wooden buildings from moisture is due to the fact that the use of traditional waterproofing materials(roofing felt, for example) is not always effective and does not provide complete isolation.

However, with the advent of modern high-tech materials that provide effective protection of wooden structures from moisture, all issues regarding the organization of waterproofing of such a bathroom can be 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 a large selection of waterproofing materials, which (according to 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 the addition of chemical reagents and crushed sand.

The basis for applying waterproof liquid formulations serves as pre-laid waterproofing sheet or roll type with a layer of reinforced fiberglass laid over it. This combination of 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.

Waterproofing the floor

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 a wooden floor covering, 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 doing this part of the preparatory work, first of all, you will need to prepare a special frame for. In this case, waterproofing measures come down to the use of a special moisture- and vapor-proof film placed between sheets of drywall and a wooden wall.

When finishing walls with OSB boards, special preparation for applying a layer of waterproofing is not required. 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 the waterproofing material itself should, if possible, belong to the same class, that is, have a similar base. 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.

It is advisable to begin protective treatment of 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 a 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.

Watch a video about arranging a bathroom in a wooden house:

Waterproofing is a hidden process, the results of which are hidden under the finishing materials of the bathroom, so many home owners are not aware of its existence and beneficial properties.

But as practice shows building construction and materials that are constantly in contact with moisture become unusable over time, especially for wooden structures. That’s what we’ll talk about today - in this article we’ll look at how to waterproof a bathroom in a wooden house.

What do you need to know?

A wooden building, due to the characteristics of the material from which it is made, requires more careful care than, for example, a stone building.

Wood is a living material; if it gets wet, it swells, and when exposed to high temperatures, it dries out, decreasing in volume. Due to these properties, the structure of the building is constantly in motion, which has a detrimental effect on the integrity of the structure.

To avoid this, high-quality waterproofing is required in rooms with high humidity, which include the bathroom.

Waterproofing a bathroom in a wooden house comes in two types:

What is the difference between waterproofing a high-rise building and a wooden house?

When doing renovations in an apartment in a multi-storey building with your own hands, and installing waterproofing in the bathroom, you will probably think that in wooden houses things should be completely different.

But this is not true except for some points. Due to the fact that waterproofing is primarily a waterproof layer. It doesn’t really matter what you lay it on - concrete or wood.

It is only necessary to treat the wood with special water-repellent compounds, such as varnish or stain, if you apply wet polymer-cement waterproofing. Bitumen mastic has good adhesion and easily sticks to wooden structures, and then the usual cement-sand screed and ceramic tiles are glued.

Also, in wooden houses, attention should be paid not only to the floors and walls, but also to the ceilings.

If you have an underground space under the bathroom, then it is imperative to waterproof it too. This is usually done using rolled welded or pasted materials.

Materials and tools needed for work

So, you are about to waterproof your house with your own hands. Let's first look at the tool you will need for this task:

• roller;
• wide brush;
• putty knife;
• construction knife;
• yardstick;
• trowel and rule (when using polymer-cement compositions)
• gas-flame burner with a propane cylinder (when using fused rolled materials).

Now it’s time to look in more detail at the materials needed to waterproof a bathroom in a wooden house.

Step-by-step instructions: how to make waterproofing

Since waterproofing in a bathroom in a wooden house will be done both on the floor and on the walls, we will consider each process separately.

Before starting work, the floor must be prepared by removing all debris and dust. Then, if it is roll waterproofing, the sheets should be cut to length with a margin for overlap and laid on a floor previously primed with mastic.

If you use roofing felt, the seams need to be heated gas burner. If you use coating waterproofing, then everything is simpler; apply the composition to the floor with a brush or roller, wait until it dries and you can begin the following work:

Waterproofing scheme for a wooden bathroom

Particular attention should be paid to communications passing through ceilings. In these places, the pipes must be wrapped with a special tape, and then filled well with bitumen mastic:

Waterproofing walls is performed in different ways, depending on the materials from which it is made. If round timber was used, then a rational solution would be to install a plasterboard system, with the installation of film waterproofing between the wall structures.

If timber was used or OSB boards, then it will be easiest to carry out coating waterproofing with bitumen mastic; before applying it, you should thoroughly treat all cracks and chips, then apply a layer of waterproofing, and then a second layer perpendicular to the first:

What mistakes are most often made during such work?

A common mistake when installing waterproofing with your own hands is an unprepared surface: due to voids or some kind of contamination, the waterproofing material may poorly adhere to the surface and subsequently moisture will begin to enter there and destroy the material.

They also can’t stand it technological process, for example, they begin to load the waterproofing layer without waiting for it completely dry, which also leads to its damage.

In a word, if you are not confident in your abilities, then it is better to turn to professionals. For your information, we provide the following approximate prices for their services. Device roll waterproofing will cost you from 300 rubles per 1 sq.m., the price of a coating ranges from 320 rubles. up to 360 rubles, wrapping will cost from 330 rubles to 380 rubles. for 1 sq.m.

To summarize, it can be noted that by waterproofing the bathroom of a wooden house with your own hands, you can safely forget about the presence of any threats associated with flooding of the lower floors or damage to expensive materials. This means comfort and tranquility in your home are guaranteed.

Wood is a natural material with unique properties. It is a natural regulator of humidity levels due to its porous structure. When humidity is high, wood absorbs moisture; when air is dry, it releases it into the atmosphere. It is these amazing properties of natural material that should be taken into account so that the waterproofing of a wooden floor in the bathroom is of high quality and reliable. It must be remembered that when wood is exposed to moisture, mold, dampness, and fungus may appear, so this stage of repair and construction work must be approached with the utmost seriousness.

The nuances of waterproofing a wooden floor

Waterproofing a wooden floor is a set of measures aimed at ensuring reliable protection natural material from the destructive influence of moisture. Poorly executed installation of this layer can lead to the impossibility of further operation of wooden structures.

A secret from the professionals!

There is a little trick when installing waterproofing. In the bathroom, the floor level should be lowered a few centimeters below the existing floor level in the other rooms. It is also necessary to separate the bathroom from other rooms with a small threshold. In the event of a water leak, these measures will ensure that it is delayed for some time, which will be enough to eliminate the trouble.

To perform waterproofing in the bathroom, the following methods are usually used: coating, painting and pasting.

Preparatory work

Waterproofing should begin with preparatory work. The first stage of the work process begins with an inspection of the condition of the floor in order to determine the scope of repairs, technology and materials.

Then they begin to prepare the base, clearing it of dust and debris. Thorough cleaning is very important, since it is impossible to waterproof a wooden floor at the proper level without complying with this requirement. Any cracks or holes that appear must be sealed with wood mastic to ensure the reliability of the protective layer. After completion of these works, the surface is finally cleaned of any debris and dust. It is also necessary to treat the wooden floor against mold using antiseptic impregnation.

On next stage it is necessary to prime the floor to ensure good adhesion of the waterproofing materials to the surface. It is better if the primer is of the same class as the waterproofing compound.

To prepare a solution of the correct consistency, take 1 part dry primer and 1 part water. Ready solution should resemble thick sour cream. Before carrying out the main waterproofing work, the primed floor must be thoroughly dried.

All joints and corners should be taped with a special waterproofing tape, which provides high-quality protection from moisture in dangerous, vulnerable places. Now you can proceed directly to waterproofing the wooden floor in the bathroom.

Coating method of waterproofing

Coating waterproofing of the floor in a wooden house has good water-repellent properties, is different simple process styling

First, a waterproofing solution is prepared. The dry mixture is diluted with the liquid component in a 1:1 ratio and thoroughly stirred until smooth. Ready-made bitumen mastics are also widely used. The prepared solution is applied with a roller to the surface in an even layer, and then hard to reach places use a spatula or brush. The consumption of waterproofing composition is about 2-3 kg/m2.

When covering the surface, it is necessary to remember the walls, applying a layer of waterproofing to a height of 5-10 cm above the expected floor level. The result is a so-called “trough” that reliably prevents the penetration of moisture.

Waterproofing is carried out in two layers, maintaining a time interval of 4-6 hours between their application. It should be taken into account that the second layer is applied perpendicular to the first. After completing the work, you need to dry the waterproofed wooden floor for 24 hours, and then you can begin performing other repair work.

Painting method of waterproofing

The painting method is a worthy alternative coating waterproofing. This method is more accessible and easier to apply, but has one serious drawback - the fragility of the result. Waterproofing made by painting will last while maintaining its protective properties 3-5 years.

Painting waterproofing consists of applying a special mixture (bitumen, bitumen-polymer mastic) to the surface using a roller or brush. It is best to paint a wooden floor in three stages. The break for drying the surface between the first stages should be 2-3 days, and between subsequent stages - 5-6 days. This method is based on the restoration natural properties wood during impregnation, which will ensure the reliability of the waterproofing coating.

Since wooden floors are especially sensitive to moisture, you can take additional measures to be on the safe side. In this case, on wooden boards The floors are laid with soft linoleum, cut taking into account an allowance for the walls of 5 cm. This method allows you to reliably protect wooden structures from negative influence moisture.

Linoleum is laid with the joint folded upward. After that, the linoleum is fixed with glue in places of contact with the walls and generously filled with silicone.

This is interesting!

It should be noted that waterproofing compounds have the ability to penetrate into the wood, restoring its properties and reliably protecting it from moisture.

Pasting method of waterproofing

The gluing method of waterproofing a wooden floor in a bathroom involves laying a multi-layer waterproofing carpet on the surface. For these purposes, roll and sheet materials are used, which are mounted at high temperature.

Pasted waterproofing is carried out by gluing bitumen-polymer, bitumen-roll, polymer materials to wooden floor using bitumen mastic. Apply the composition in a uniform layer of 1.5 mm to the entire surface and begin rolling out the roll or sheet material. The whole process is then repeated to achieve required quantity layers.

At the end of the work, the edges of the material are treated with a special waterproofing putty, which contains polymer impurities.

Pasted waterproofing is very demanding to maintain. thermal regime in progress. Polymer, bituminous materials it is necessary to lay under the influence of temperature treatment, which becomes a difficult task in the absence of special tools and practical experience.

Need to know!

Roll materials for adhesive waterproofing soften under the influence of temperatures of 45-55 degrees.

Types of wood for bathroom floors

The reliability and effectiveness of floor waterproofing depends to some extent on quality characteristics type of wood used. The most important property is good moisture resistance.

There are several types of wood that are most suitable for flooring:

1. Larch - best option, quite resistant to moisture.
2. Cork flooring is one of the acceptable options; it is resistant to moisture and has high strength. This flooring has good decorative properties and is almost non-slip.
3. Teak is an expensive solution for the bathroom; it is not afraid of moisture, as it contains a high concentration of essential oils. It is characterized by a long service life provided that the cracks between the boards are carefully filled with sealant.
4. Thermowood - popular new material, which is wood that has been treated with steam at high temperatures (over 220 degrees) in an oxygen-free environment. Thanks to this treatment, thermowood acquires increased resistance to fungi, as well as reduced water absorption.

Naturally, when interacting with water or moisture, the wood will begin to swell and rot. Therefore, the issue of reliability of waterproofing of a wooden floor should be given great attention at all stages of the work.
