Types of waterproofing for a wooden house. Floor in a bathroom in a wooden house: device, waterproofing and choice of coating

The wooden house is, in fact, alive. He always seems to be on the move. It began to rain - the wood swelled, the sun came out - it dried up a little. In addition, it is a natural material, and nothing “natural” is alien to it: wood rots, molds, it is affected by a fungus, and in the tropics it is devoured by termites. Termites for the middle lane, however, are not an actual problem, but shrinkage noticeably changes the geometry of the entire building over time. So the arrangement of a bathroom in a wooden house is not a trivial task.

Competent waterproofing - perhaps the most important question, the answer to which the summer resident will have to look for.

● Firstly, you should try to apply the latest technology and use the most flexible waterproofing materials with high water repellency (hydrophobicity), water resistance and good adhesion to any surface (high adhesion).

● Secondly, it is reasonable to entrust the work to professionals, or follow the manufacturer's instructions in the most careful way.

To date, gluing and coating materials are used for waterproofing floors and walls in the bathroom.

Pasting waterproofing in the conditions of the bathroom is quite difficult to apply. But if you still settled 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, it is possible that it is still at the project stage.- it is worth dwelling on the technology of coating waterproofing. At least for the reason that this type of waterproofing is characterized by high, and most importantly, stable rates of stretching and recovery. What is especially true for houses built of wood.

Coating waterproofing- these are polymer-bitumen mastics that go under the screed, and polymer-cement mastics, they are applied over the screed. Capillary rubber-bitumen mastic has very good performance, the protective layer of which is preserved even with deformations of building structures. It can be applied to the screed.

Polymer-cement mastics are two-component elastic waterproofing coatings. One component is a powder mixture containing moisture-protective 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.

Today, most of society has realized that it is better to live in eco-friendly wooden houses. Such a house breathes, has a good appearance and keeps heat for a long time. In order for the house to stand for a long time, and you can be proud of its appearance, you need good waterproofing of the outer walls.

The primary, of course, is the waterproofing of the foundation of such a house and it is good to perform waterproofing of the basements. But the protection against moisture of the walls, both inside and outside, also occupies not the last place. Let's take a closer look at what waterproofing of external walls is. We will learn what materials you need to use and how to do such work yourself.

If you do not protect the walls of a wooden house, then the tree will quickly begin to rot and become covered with fungus. Today using mainly measures:

But, as you know, fungus and mold appear in places where humidity is high. Wood fiber absorbs moisture very well inside and keeps it there for a long time. And at high temperatures, the tree will begin to rot and rot. In cold weather, it will simply freeze, which will lead to heat loss and soaking of the walls. If the fungus has already appeared, it is difficult to get rid of it, and the whole family will breathe in the spores of this wood enemy. It helps to get rid of:

• waterproofing the walls of the house;
• fungicide treatment;
• plastering at home;
• whitewashing with lime.

When protecting a building, a number of actions are performed. This:

• external waterproofing of wooden walls;
• ventilation of the facade of a wooden house;
• internal waterproofing.

Moisture protection of the outer walls of a wooden house is one of the most basic tasks of repairing or building a wooden house. This work must be done professionally and efficiently. It will depend on this what humidity will be inside the house, as well as how long it will last.

Materials for external waterproofing

Today in the construction market you can find a fairly large variety of materials. If you ask professionals how to choose the right material, then your attention will be paid to the humidity in the house itself, the type of construction of your building, where your home is located. This is what the choice will depend on.

Wall waterproofing can be done in two ways:

1. Spraying.
2. By hand

In this case, the following types of protection are used:

1. Coating
2. Plastering.
3. Okleyechny.

Between the foundation and the wall itself, even during construction, there must also be waterproofing. It is called horizontal protection. As a rule, in such cases, rolled or coating special material is used. Roofing material is most often used as a rolled pasting material. It is pressed against an already prepared wall and heated from above with a torch. After that, they pass and level everything with a roller. From above, such a structure is closed either with insulation and cashing, which can be, for example, siding.

In any case, the external waterproofing of the walls must be linked to the waterproofing between the wall and the foundation. And there, as a rule, they use the same roofing material. I treat the lower logs from the foundation with special antiseptics, or with simple used engine oil.

Plaster waterproofing

The plastering system is considered one of the most durable. But it is practically not done on wooden walls. It is applied to already cleaned and prepared walls. For this, special waterproof plaster mixtures are used.

Apply them with a spatula to the prepared and primed surface. The application thickness is approximately 2-5 cm. It is necessary to apply in layers, allow each layer to dry thoroughly. Such waterproofing is considered very resistant to cracking, but is not protected from mechanical stress.

On top of such a plaster, a layer of a special primer is applied, and then paint. In terms of complexity, this is one of the most difficult waterproofing.

Coating waterproofers for walls

This type is a multilayer coating of the wall with a special waterproofing composition. Today on the market you can find many materials, for example, as bitumen-polymer and acrylic - polymer mastics, various sealants, liquid glass.

Usually, when performing these works, crack-bridging compounds, silicification concentrates, and bitumen emulsions are used. They cover the wood well and clog all pores. Forming on its surface like a film that can not let water in and repel it.

The coating mixture can be applied hot or cold. It all depends on the material you choose. For such work, a construction spatula, brushes are used. This waterproofing has a long service life, it is approximately 50 years. Of course, it all depends on the quality of the material chosen.

Do-it-yourself installation of coating-type waterproofing

Consider installing a waterproofing coating on the outer wall of a wooden house.

For this you will need:

1. TechnoNIKOL Mastic MGTRN (you can take any material that suits you)
2. Brush or roller.
3. Wood primer for bituminous waterproofing.
4. Skin.
5. Brush.
6. Spray.

The first step is to thoroughly clean the external walls from dirt. To do this, you can even lightly sand them on top and clean them well with a brush. We apply a primer on top. It can be applied with a sprayer, a simple garden sprayer will do for this purpose. Let it dry well after application.

The next step is to apply waterproofing. We chose TechnoNIKOL. This waterproofing has a deep penetrating effect and dries quickly. With it, you can glue roll-type waterproofing to rough and dusty surfaces. But in itself it is already ready protection.

We apply it on the walls with a brush, where the brush does not fall, just pour the solution and remove the excess with a spatula. Let it dry well after application. When it has ceased to stick when touched, apply a second layer on top. After it dries, apply the third layer.

After complete drying, you will get a good waterproofing of the outer wooden wall, which will not be afraid of moisture or bad weather. From above, such a system is usually decorated with cash. It can be both lining and siding.

Adhesive hydromaterial for plinth

The gluing waterproofing agent is applied, as a rule, in one layer, but to achieve a more durable waterproof surface, it can be applied in several layers. During this treatment, the material is pressed tightly against the already prepared walls of the basement and treated with a simple burner, after which it is smoothed with a roller. Most often in such cases, roofing material is used.

You can apply and glue such material in a cold way. This is done using bituminous mastic.

The material is also applied to wooden walls between the cashing and the wall. Insulation is laid between them, but this is at the discretion of the owner of the building. It is good to use ventilated facades for cashing with such waterproofing. Moisture in such cases will not accumulate on top of the waterproofing, but will be pulled out like a pipe.

To protect such waterproofing, a specially made clamping structure is often used.

Do-it-yourself installation of gluing waterproofing of external walls

You will need:

1. Rolled ruberoid.
2. Rubber roller.
3. Brush.
4. Sandpaper.

The first step is to thoroughly clean the walls of the basement of the house from dust and dirt. Here you can just walk with a brush and remove all the debris, but with a deeper clog, go on top of the emery. After that, carefully clean the walls again.

Now a rolled roofing material is taken and rolled out, starting from top to bottom. It is pressed tightly against the wall of the basement and a burning gas burner is passed over it from above. The roofing material under the influence of fire will melt and begin to stick to the wall. A soft and molten roofing material is carried out with a rubber roller. It is necessary to level the wall, and expel all the air from under the roofing material sheet. Making such a system is quite difficult, and you will need an assistant.

So do each sheet. Until the whole building is sheathed. From above they make an outline that will additionally press the sheets to the building. And only then they insulate and mount the cashing.

Waterproofing walls with impregnation

Today, there are many wood impregnations that fill microcracks in the tree and cover the logs of the house with a waterproof film. In this case, the appearance of the tree will not change.

One of these impregnations can be called liquid glass. This impregnation has long been used as a waterproofing agent. It is sold in all major hardware stores. It has a light gray or yellow color. By covering the logs with such material, you can be sure that they will no longer be afraid of moisture.

Do not forget that no matter how strong and reliable the waterproofing of the walls is. Without waterproofing the foundation, it makes no sense. So any protection from moisture must begin with the foundation and basement of the building, and only then move on to the walls.

It is not recommended to cash out the building without preliminary waterproofing of the walls.

It doesn't matter which wall waterproofing you choose, what matters is what material you use. The result completely depends on the quality material and the plus of conscientious work. It is better to entrust such work to professional firms, but with a little diligence and work, you can do such an installation yourself.

Any dwelling, be it multi-storey panel houses, private wooden, brick, must be protected from moisture. Waterproofing should be carried out not only from the outside, but also in such rooms as the kitchen, bathroom, bathroom. This stage of work is necessary, if you ignore it or do something wrong, mold and fungus may appear. Gradually, this can deform the walls, and the structure will not be as strong as before, which will subsequently lead to destruction.

Having made capital waterproofing, you can avoid many problems. This is especially true for the bathroom. There it is necessary to waterproof not only the walls, but also the floor. As a rule, waterproofing wooden walls is much more difficult than brick and panel walls.

Any room must be insulated from moisture

What are the waterproofing materials?

The most common waterproofing methods are gluing and coating. The first has its advantages and disadvantages - you can continue to work on after 24 hours, but pasting is a painstaking work in itself. It is possible to impose both the well-known roofing felt, roofing felt, and more advanced materials - ecoflex, isoflex or some other. Among them, adhesive ones are distinguished - the protective layer is simply removed from them, and the material is ready for use, and built-up - the adhesive layer that they have must first be heated. To do this, use a gas burner. You just need to remember that this type of waterproofing will add 5 millimeters to the main floor height.

The second method - coating - is a simpler option. The materials used perfectly stick together with any surface, are able to endure high temperatures. Coating materials are divided into several types.

The simplest option for waterproofing is coating. It sticks easily to any surface.

Now there are many different waterproofing materials in stores, they are divided by type: painting, sticking, impregnating. The first includes mastics and emulsions. They allow you to create a reliable waterproof layer. Apply to the surface in layers after a certain time. The second group is a film or roll material made on a polymer or bitumen basis. To stick it on a plane, you need cold or hot mastic. It is better to overlap the material so that moisture does not penetrate into the seams, and for pouring use moisture-resistant cement-based compounds.

The third group includes all materials, where the components include moisture-repellent cement, chemicals, and crushed sand. It is undesirable to use this type in residential buildings. For waterproofing in the bathroom, the first and second groups are mainly used. They can be combined with each other.

Mastic will create a reliable waterproof layer

How to properly apply waterproofing material?

As in any repair work, before waterproofing, the surface must be cleaned of dirt and dust and primed. After the primer dries, you need to pour the bituminous mastic in one layer, especially carefully close the cracks in the corners and in those places where communication takes place. It is important to remember that while the mastic dries, it is forbidden to dust. After 24 hours, you can apply a layer of canvases. This should be done with an overlap of about 10 cm.

Cloths should be laid with an overlap of 10 cm

An important point - the floor in this room is better to do lower than in other rooms. This is recommended so that in the event of an unexpected pipe break or leaking faucet, water cannot escape from the bathroom and flood the entire house. With high-quality waterproofing, water will not get into the basement. Among other things, your home will be reliably protected from dampness, because prolonged exposure to moisture on building materials such as wood can adversely affect it. In addition, properly carried out work will prevent the appearance of mold and decay and relieve many problems.

The floor in the bathroom should be made lower than in other rooms

Features of working with wood

Wood, as a natural material, has exceptional properties - it absorbs excess moisture, and gives it away when it is lacking. Because there is a lot of excess moisture in the bathroom, not every tree is suitable for construction work and flooring in this room. The material must have such a property as resistance to water absorption. Even if you have carried out high-quality waterproofing, it is better to use the following types of wood for work:

1. Thermotree. It appeared on the construction market not so long ago, but has already established itself only on the positive side, is popular. The material got its name because the wood is processed with steam at high temperatures. After such a procedure, the wood becomes resistant to mold and fungus and almost does not let liquid through. It has only one drawback - high cost.
2. Larch. The most acceptable material for construction work. It has great resistance to moisture. Average price equivalent.
3. Corkwood. High resistance to moisture, the material is strong enough, durable.
4. Teak. From this material, the coating will be strong and non-slip. Since the structure of the tree contains a lot of essential oils, so it does not allow moisture to pass through. It is quite expensive. But, as they say, the price corresponds to the quality.

Even if the tree is highly resistant to moisture, waterproofing work should be carried out with high quality.

Thermal wood has only advantages, but the cost of such material is quite high.

Important points of waterproofing in the bathroom

As a rule, the materials that are used in waterproofing do not allow liquid to enter from the outside. There are those that can pass air through the smallest pores. The main thing is to carefully carry out waterproofing in the corners and in those places where communication is located - it is there that there are a lot of cracks and cracks, they must be carefully repaired. If you applied mastic to the floor, it is important to prevent dust and various contaminants from getting on the floor. The rest of the work is carried out when the mastic is completely dry - after 24 hours.

If you use rolled materials, they should be overlapped by 10-15 cm. The floor must be made lower than in other rooms. Such a recess will not allow flooding the entire room. If this is not possible, then you need to install a high threshold - it will prevent water leakage. Another important point is a competent approach to choosing a tree.

Roll waterproofing should be overlapped by 10-15 cm

Before you decide how you will waterproof, it is important to consider some features:

• What material is the cover made from? its preliminary state;
• how long it will take to carry out all the necessary work; what floor is the bathroom on;
• whether it is necessary to reduce the height of the room, its area;
• how difficult is the shape of the room;
• what tools might be needed;
• your financial capacity;
• Will you be able to do the work yourself or will you have to turn to specialists.

Before starting work, it is worth calculating everything to the smallest detail.

Waterproofing wooden walls in the bathroom

Before starting work on waterproofing, the surface must be thoroughly prepared. All existing gaps, cracks must be covered up or filled with a special agent that will provide protection from moisture. To avoid the penetration of liquid deep into the wood, wax should be applied to the surface. If you use rolled materials as waterproofing, it is better to treat the joints with mastic - this will better protect the tree from moisture, because tiles are not always laid up to the ceiling. And in order to stick it, it is important that the walls are even. If this is not the case, it is necessary to level them, that is, to plaster, using the building level.

After the walls are leveled, we use a polymer cement composition as a waterproofing. In places around the sink and behind the bathroom, it must be applied in three layers. Before applying the next layer, it is necessary that the previous one is completely dry, but not dry. Only then can you lay the tiles, starting work from the floor.

Preparing for waterproofing work

Before laying waterproofing materials, it is necessary to remove the old flooring, cladding, all dirt, dust, debris, wash the walls, floor, and let the wood dry. Then the tree must be treated with an antiseptic, the necessary moisture-repellent agents, and the surface should be thoroughly leveled. Existing cracks, cracks are covered with special means.

Before starting work, you need to remove the old materials and clean the walls and floor

The next stage of work will be applying a primer to the floor and walls - this contributes to good adhesion of the waterproofing to the base. Let's dry well. A waterproof tape is applied to the joints between the floor and the wall, ceiling and wall, in hard-to-reach places, corners - it will not allow moisture to get into the joints between the bases. Not only walls, floors, but also ceilings need to be treated with waterproofing materials. The basement under the bathroom also needs to be waterproofed.

Primer must be applied to walls and floors

Work order

After you have prepared the room for further work, it must be thoroughly dried. Next, you can waterproof the wooden floor in the bathroom. Before work, decide whether you will do everything yourself or contact specialists.

First of all, logs are mounted on the surface and insulation is laid. It can be polystyrene, mineral wool or expanded clay. It is covered with moisture-resistant plywood, which is fixed with self-tapping screws. The next step will be the preparation of the waterproofing material - you prepare the composition or cut the rolls to the required length. We lay the mixture on the base, glue the rolled strips. The material should go onto the walls to a height of 15-20 cm in order to form a kind of "trough", in case of a leak it will hold the liquid. Waterproofing is laid perpendicularly.

Upon completion of work, everything must be thoroughly dried. Then you can carry out a fine finish - lay tiles, stick PVC panels or use any other material to your taste. It all depends on your financial capabilities.

After all the work is done, let the room dry.

Implementation of pasting moisture protection

For pasting waterproofing, film or roll materials are used. They are either glued or fused, usually they are applied in 2-3 layers. For work, bitumen-polymer, polymer, bitumen-containing materials are used. Mastic for gluing use polymer, bitumen-rubber, bitumen, bitumen-polymer.

First of all, a thin layer of mastic is applied to the prepared surface, then a roll is rolled out, it needs to be fixed, and the surface is again smeared with mastic. This procedure must be carried out several times. The material is glued to the walls, starting from the floor. Which waterproofing method you choose will depend on your budget and how often the space is used.

Adhesive waterproofing is glued to the mastic

Do not ignore waterproofing. After all, it will not only protect against mold and fungus, but also increase the life of the room.

For waterproofing a bathroom in a wooden house, coating materials (mastics and impregnations) are used. Given that the work is carried out from the inside, you need to buy latex mastics, they do not contain solvents, respectively, there is no smell when applied. The waterproofing of the bath is carried out with roll materials (reflective insulation and diffusion membrane), which are more needed to protect the insulation.

Waterproofing a bathroom in a wooden house

Very pretty, but extremely impractical.

Waterproofing a bathroom in a wooden house, unlike an apartment, is applied to all internal surfaces. The protective layer must be seamless to completely exclude the penetration of moisture. Recall that in a bathroom with concrete walls and floors, only wet areas can be treated. The tree is prone to soaking moisture, from which, over time, mold appears in the material, it begins to crumble. Although there are some breeds that do not rot. For example, teak, which is used to build ships.

Of course, no one builds teak houses, conifers are usually used, since they are cheaper. There are various impregnations that reduce the degree of moisture absorption of wood, but still such treatment will not be enough for a bathroom. Here you need a major waterproofing of the bathroom in a wooden house. You can’t do without a screed on the floor and wall cladding with a plasterboard ceiling.

Wooden floor waterproofing

Waterproofing under the screed is laid with an overlap on the walls.

The first step is waterproofing the floor in a wooden house. Before pouring the screed in the bathroom, you need to spread a protective film on the subfloor. To do this, you can use ordinary polyethylene or PVC membrane. The use of bitumen rolls is allowed, but indoors, installation turns into torture. The adhesive surface of the rolls must be heated with an open flame, while poisonous smoke is released, an ordinary respirator does not save.

Tapes (any of the above) are laid with an overlap on the walls in such a way that the wood does not come into contact with the mortar. A damper tape is preliminarily glued along the perimeter of the bathroom, which will compensate for the expansion of the concrete screed during operation. If floor heating is planned, then it is necessary to lay thermal insulation (polystyrene foam or extruded polystyrene foam). You can then mount for the underfloor heating system. Why metal-plastic, and not or PPN:

• aluminum reinforcement reduces thermal expansion;
• the ability to bend the contour at the desired angle, respectively, the absence of joints;
• shape retention after bending - PEX pipes do not hold their shape and return to their original position (100% shape memory).

There is a special waterproofing of the wooden floor in the bathroom with mounts for the contour - this is a foam covered with a polymer, which is available in mats. A screed is poured over the metal-plastic pipes, if a floor heating system is not provided, then concrete can be poured directly onto the waterproofing even without . The wooden floor is already protected from moisture, but concrete also absorbs moisture, so it must also be waterproofed before laying the tiles.

You can use two types of waterproofing for a wooden floor under a tile - these are latex mastic and penetrating compounds.

Latex mastic does not contain solvents, so there is no pungent odor. Apply by brush or roller. It is allowed to perform installation by the bulk method - this is when the mastic is poured directly onto the floor and distributed with a wide spatula (similar to a leveling screed). After polymerization forms a protective film on a surface. Inexpensive and high-quality mastic is produced by the Knauf company, the name Flehendicht.

Impregnations are cement-like powders that are diluted in water and applied to concrete with a brush. Penetrate into his pores and clog them with crystals. As a result, the screed becomes waterproof. The composition is caustic, do not allow contact with the skin to avoid chemical burns. A proven penetrating composition of domestic production is Penetron (the price is low, and the quality is high, if properly bred).

Waterproofing wooden walls and ceilings

The walls sewn up with drywall are covered with latex mastic.

Wooden walls and ceilings definitely need to be sewn up with drywall. There is a special drywall for wet areas, but it is still subject to the destructive effects of water, although to a lesser extent. In any case, you need to do the waterproofing of the bathroom in a wooden house with your own hands, especially since there are no difficulties in this.

As a protective material, only latex mastics should be used, already familiar to us by Knauf Flehendicht. Mastic is applied in two layers:

• the first - vertical movements;
• the second - horizontal movements or vice versa.

Recall that waterproofing is applied in a continuous layer. The hardened mastic will also protect the structural elements made of wood from steam, which is very abundant in the bathroom. Pay attention to wall-to-ceiling and wall-to-floor joints. They must be treated with special care or stick a self-adhesive waterproofing tape. On the hardened latex mastic, you can lay tiles or paint it. Do not forget about the hood. A good ventilation system is a must. It is also necessary to install a water or . This is primarily a heating device, and only then a means for drying clothes and towels. Without a heat exchanger, the bathroom will be damp.

Waterproofing in a wooden bath

Waterproofing in the bath protects the insulation from moisture.

Waterproofing the floor in the bath according to technology is no different from laying protective compounds on the ceiling and walls. Everything is done according to the following algorithm (layers from the inside):

• wood finish;
• air buffer zone;
• vapor barrier;
• mineral wool;
• membrane (walls are an exception - a membrane is not needed).

To clarify, let's deal with the terms waterproofing and vapor barrier, because these are not the names of materials, but the definition of the function of the layer. Let's look at an example. As a vapor barrier in the steam room, Penofol is used - foil glued to a foam polyethylene pillow. Penofol does not let steam through, but at the same time it retains water, it turns out that the layer performs two functions at once.

To the waterproofing of the wooden floor in the bath include:

• Penofol, which is laid on top of the insulation and does not let water or steam through;
• a diffusion membrane, which is laid below the insulation and does not allow moisture to pass from the ground, while releasing steam and a heat-insulating cake.

The same applies to waterproofing the ceiling of the bath. The only difference is which side to put the diffusion membrane. Two types of membranes can be used: single-layer PVC and three-layer polypropylene. Separately, we note the importance of the air buffer zone between the finish and . Penofol is laid with foil to the heat source, that is, inside. The glossy surface reflects IR rays back into the steam room. IR rays are transmitted only through the air, if the foil touches the finish, then the method of heat transfer will be completely different. Therefore, in order for Penofol to work as a reflective insulation, a gap of at least 15 mm is required.

Results

The walls, floor and ceiling of the bathroom in a wooden house need to be protected from moisture. To do this, a polyethylene or PVC membrane is laid on the floor and a screed is poured. Before laying the tiles, the screed is treated with penetrating waterproofing or coated with mastic. The walls and ceiling are sewn up with gypsum, on which latex mastic is also applied (preferably Knauf Flehendicht). Wall-floor and wall-ceiling joints are glued with self-adhesive waterproofing tape.

Laying the waterproofing of a bath with your own hands is needed to protect the structural wooden elements and mineral wool (you can’t do without insulation in a steam room). Two types of waterproofing are used: penofol and diffusion membrane. The membrane is placed only on the floor (under insulation) and the ceiling (on insulation), it is not needed for walls. Penofol is always placed from the side with a pair of foil inside. A gap of 15 mm is required between the reflective surface and the finish.

Building a house is an important, responsible business. The dwelling should be bright, warm, high humidity should not be allowed in it. It not only significantly reduces the life of a wooden house, contributing to rotting, the spread of mold and fungus, but also harms the health of the owners. Therefore, waterproofing a wooden floor in a bathroom: the materials and technologies that are used in this case are serious issues worthy of a detailed discussion.

Floor waterproofing device

Sudden leakage of water pipes, clogged sinks, elementary forgetfulness, in order to protect yourself from the unpleasant consequences of flooding, you need to take care of high-quality waterproofing of the bathroom.

A protective coating made in the form of an airtight tray will not allow water to penetrate into other areas of the house and will minimize possible problems. It prevents the spread of fungus and mold, which in a wooden house will not only make all efforts to repair useless, but can cause real troubles, for example, damage to floors and serious harm to health. Therefore, the waterproofing of wood requires special attention.

Waterproofing a bathroom in a wooden house is carried out using coating or roll insulation, when special pasting materials create an airtight cover.

The basis of waterproofing compositions is bitumen and polymer additives. The use of the latter improved the quality of the presented products, their strength, ductility and service life.

Types of insulating materials

Today, there are many types of waterproofing with different methods of application and degree of protection. The main types of waterproofing materials:

• spraying;
• injection;
• penetrating;
• painting;
• plastering;
• coating;
• pasting.

The floor in the bathroom in a wooden house is waterproofed by painting, coating or roll methods. It is better to entrust the choice of a waterproofing coating to an experienced specialist, since high-quality waterproofing of a bathroom in a wooden house helps to forget about many problems.

What you should pay attention to when arranging a bathroom in a wooden house

1. In a wooden house, the bathroom is best placed 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 necessary gain to a competent specialist.
2. It is more convenient to place rooms with high humidity on top of each other and thoroughly insulate both rooms and ceilings. In the event of a leak, this will cause a minimum of damage, among other things, such a layout will reduce the cost of plumbing wiring.
3. It is necessary to provide for a height difference at the site of the future bathroom, this will greatly facilitate subsequent finishing.
4. Not only the floor needs waterproofing, be sure to protect the walls and ceiling.
5. Provide good ventilation, this will help to avoid many problems.
6. Waterproofing may be needed not only for the bathroom, do not be too lazy to protect the kitchen, bathrooms and rooms where the washing machine is located.

Where there is a lot of washing, there is always high humidity, and the likelihood of water leaking from pipes is often unpredictable Source webcatalog.vitromex.com.mx

Waterproofing the floor in a wooden house, in the bathroom, is carried out in several stages.

On our site you can find contacts of construction companies that offer house design services. You can directly communicate with representatives by visiting the exhibition of houses "Low-Rise Country".

Preparatory work

First, a thorough preparation of the base is carried out. It is cleaned of debris, dirt, dust. To seal the cracks, use a special mastic for wood. It is desirable to treat wooden logs with an antiseptic and special protective impregnation.

Between the lags for insulation and additional noise insulation, a layer of expanded clay, mineral wool, expanded polystyrene or ecowool based on flax fiber is placed. The choice depends on the preferences and financial capabilities of the owner of the house.

The insulation is covered with sheets of plywood with moisture-resistant impregnation or cement particle boards.

Wooden sheets must be impregnated, this will significantly extend the service life Source indigostroy.com

Further, the plates are treated with a waterproofing primer for additional protection of the coating. The primer should dry well. It is necessary to ensure that dust and dirt do not get into the room during the drying process.

Important! it is better not to do a cement screed in wooden houses because of the heavy 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 compositions. It all depends on the choice of the consumer.
