In order to prevent moisture from entering the room from the basement or to protect the floor from water in the kitchen space, in the bathrooms, waterproofing is installed, which is placed under the screed.

The construction market offers a huge selection of materials that insulate the floor from moisture. For example:

• liquid glass - is a coating material;
• waterproofing underfloor heating - roll materials are used.

Let's consider different types of waterproofing, technologies for its use, and how to make it correctly.

Some apartment owners do not consider it necessary to waterproof the floor in the apartment. But there are reasons to protect the floor.

Force majeure situations happen when a lot of water gets on the floor covering, and only a well-mounted waterproofing can save the floors from damage.

Who of the tenants of high-rise buildings is not familiar with the situation when the neighbors from above flood the apartment. And although the neighbor has no malicious intent, the incident can ruin the relationship for a long time.

If we consider a private building, then waterproofing will not allow moisture and vapors to enter the room from the basement. This is especially important if the house is located on a plot with a close adjoining groundwater.

If you do not carry out high-quality waterproofing of the floor, then there will be high humidity in the room.

Floor waterproofing - what types exist

There are three types of floor insulation before installing the screed. They differ in technology and materials:

• Coating - oxidized bitumen, which contains organic and inorganic additives, such as:
  • latex;
  • plasticizers;
  • rubber crumb.

This material is made in such a composition to increase the fluidity when it is applied to the coating. After complete curing, the waterproofing covers the surface with an elastic and durable film that does not allow water to pass through.

Liquid glass, bitumen and polymer mastics - a coating material with high adhesion.

Lubricated waterproofing not only provides good protection of floors and slabs, but also serves as a reinforcing frame under the screed.

• Okleechnaya - using materials in rolls. The waterproofing composition includes polymers, fiberglass and reinforcement. Recently, manufacturers have begun to produce self-adhesive roll materials.

It should be noted that in this situation, for better adhesion of the composition to concrete, a burner is used, which heats up the insulation.

• Combined, used if the room has high humidity, kitchens, bathrooms. Such waterproofing of the floor, for a warm floor, perfectly protects the floors, and, accordingly, your neighbors from below from moisture.

It provides for the use of materials of the first and second types of insulation, which is made in several layers.

Insulating materials

There are many types of materials. The area of ​​use and properties are different, so you need to read the manufacturer's manual before purchasing.

Roll materials are:

• Hydroisol;
• Rubirod;
• Isoplast;
• Filisol.

Sold in the form of rolls, the material is very durable and is not afraid of mechanical stress.

This material can be applied to any kind of floor. The advantage of roll insulation is ease of use and low cost.

There are two ways to fix roll insulation:

• for bituminous or polymer mastic;
• heating the material with an open flame using a burner.

Paint insulation

This name is used because such waterproofing is applied under a warm floor by applying to the surface with a brush or roller. Has two methods of application - hot and cold.

For example, liquid glass is applied in a cold way, and hardens under the influence of air, this is facilitated by the special hardeners added to the composition.

All bitumen based liquid waterproofing requires preheating to flow. Bitumen is applied to the surface and, when cooled, creates a waterproof film.

When treating the floor with insulating mixtures, it is worth smearing the walls adjacent to it, to a height of 30 cm. This is especially true for wet rooms.

Bulk insulators

The material is quite in demand and easy to use, its only drawback is its cost. But thanks to this waterproofing, a monolithic surface is formed on the floor, completely insulated.

Application is quite simple, the mixture is diluted to the desired consistency, poured onto the floor and leveled with a special needle roller.

Having considered the types of waterproofing, you can start work.

Installation steps

All technologies listed above require specific tools and a specific approach. But before laying the waterproofing, we prepare the surface.

Substrate preparation:

• clean from visible dirt, dust, debris;
• cement all cracks, seams and joints of floors, including the joints of the wall and floor, with cement mortar;
• fix the damper tape along the perimeter of the room to the bottom of the wall;
• apply a deep penetration impregnation, not forgetting to treat the surface with an antifungal compound.

The primer is applied in two layers, but it is possible to prime the surface with concrete contact, which will give the insulating layer greater strength and tightness.

If redevelopment is planned, then it must be done before the start of floor waterproofing work.

Roll insulation flooring

Roll waterproofing is applied in several stages:

• It is necessary to carefully level the surface on which the material will lie. It is better to use a self-leveling floor. It is sold in bulk bags. It must be diluted with the required amount of water (look at the package). Pour the base and smooth with a needle roller.

Only after that, polymer mastic or bitumen emulsion is applied to the prepared floor. If there is not a lot of adhesive, then it will be enough to apply diagonal stripes over the entire surface.

• The roll with insulation must be heated and rolled out along one of the walls. Then we heat the edge of the material, which is adjacent to the wall with a construction hairdryer, and bend it onto the wall with an overlap of 20 centimeters.
• The next sheet of insulation should go over the previous one by 15 centimeters. As soon as the entire surface of the floor is covered with flooring, we begin to coat the seams between the sheets with mastic.
• As soon as the seams are missed, you need to take a gas burner and warm up the material well, which will soften and stick tightly to the surface.

When working on the installation of roll waterproofing, fire safety must be observed, since this material is made on the basis of bitumen, and it is flammable.

If the insulation is carried out in a damp room, then it is better to apply the material in 3 layers, which are superimposed across each other.

Installation of coating waterproofing

There is nothing difficult in this method, just pick up a roller or brush. Insulation is started from the wall opposite the exit. First of all, we coat all the walls to a height of 25-30 centimeters around the entire perimeter of the room, and then we go to the floor.

It is advisable to process the entire surface in one go. Polymer mastic and liquid glass are applied to the floor immediately after opening the package; they do not require heat treatment.

With bituminous compounds, this technique will not work, since to apply it you need to warm it up well. We take the mastic and transfer it to a metal container, which we heat with a gas torch or blowtorch. Make sure that no open flame comes into contact with the material as it may ignite.

It is necessary to apply these compositions in 3-5 layers. Each subsequent layer is applied after the previous one has completely dried.

Underfloor heating waterproofing

Many people install warm floors in the apartment. In this situation, waterproofing of a warm floor covering is required:

• apply a layer of insulation to the base;
• pour a concrete screed;
• mount a warm floor;
• pour a layer of self-leveling floor;
• mount the finishing floor covering.

The methods described above will help you to correctly choose not only the right material for waterproofing, but also to install it correctly.

Wood (a versatile and widely used building material) needs reliable and long-term protection. Conventional ones, which are mainly used for these purposes, are susceptible to cracking and peeling over time. The relatively recent rubber paint for wood that has appeared on the construction market, due to its unique composition, is devoid of these disadvantages. High consumer and technical indicators contribute to its growing popularity, especially in individual construction.

Features of the composition

The term "rubber wood paint" is not entirely correct in relation to this protective coating. Rather, it defines the properties and technical performance of a given product. In fact, the latter consists of:

• acrylic - the main synthetic polymer binder that forms a protective film on the treated surface;
• latex, which is chemically obtained from artificial rubber (it is he who gives the coating super-elastic properties);
• coalescent (for better film formation);
• pigments that give the composition a certain color;
• water as a solvent;
• antifreeze, which significantly increases the frost resistance of the coating;
• special additives and fillers that increase the resistance of the composition to aggressive media (salts, alkalis, etc.);
• antiseptic components that prevent the formation of fungi and mold.

Although almost all ingredients (with the exception of water) are produced by various chemical reactions, the final composition is absolutely environmentally friendly, safe for humans and the environment, and meets all the necessary rules and regulations.

Main characteristics

Rubber paints for wood are characterized by:

• waterproof;
• high resistance to daily and seasonal temperature changes;
• good adhesion to all building materials made of wood (timber, plywood, boards, fiberboard, chipboard and so on);
• durability (guaranteed service life while maintaining the protective properties of the coating up to 10 years or more);
• high elasticity;
• good vapor permeability (which favorably affects the "breathing" properties of wooden structures);
• high mechanical strength and abrasion resistance (especially for rubber on wood);
• increased anti-slip properties (which significantly increases safety when using, for example, stairs);
• resistance to the negative effects of ultraviolet radiation (the coating does not change color for a very long time);
• quite economical consumption at a high layer density (although this indicator is higher than that of traditional analogs);
• ease of application;
• high drying speed;
• the ability to apply on a cracked surface (without preliminary putty);
• lack of smell;
• ease of further care with the use of any household detergents.

disadvantages

It is unlikely that you can find at least one product on the modern market of high-tech and innovative building materials that has no drawbacks. So rubber paint has them, although there are very few of them:

• the treated surface will be matte (glossy shine cannot be obtained due to the components that make up the composition);
• the price for such coatings is higher in comparison with standard (alkyd, acrylic or oil) compounds.

Application area

Rubber paint for wood for outdoor use has been successfully used in the arrangement of a protective coating:

• external facades and technological building elements of supports, and so on) buildings for various purposes (from a residential country house to a garage or a barn);
• fences and barriers;
• plank floors (on open terraces, gazebos and balconies);
• elements of stairs (steps, railings, balusters and supporting structures);
• decks and platforms designed for the convenience of using artificial and natural reservoirs;

• children's playgrounds and sandboxes;
• hulls and elements of boats, boats and yachts.

Surface preparation

Naturally, the most optimal solution for arranging a protective layer is to apply rubber paint for wood outdoors on new or newly built structures and structures. The pores of the building material are not yet clogged with dust, dirt or other foreign inclusions. Durability will only benefit from this.

Old surfaces planned for processing must first be thoroughly cleaned with a spatula or scraper, and then with a metal brush or a special attachment for an electric drill.

Application method

Almost all manufacturers of rubber paints for wood for outdoor use recommend the following working conditions, the observance of which will ensure the preservation of the protective properties of the coating during the warranty period:

• The ambient temperature should be within the range from + 5 ° to + 30 ° С (the interlayer and final drying times indicated on the package are usually for + 20 ° С).
• Humidity - do not exceed 80%.

For application, you can use any painting tools: brushes, rollers, spray guns and other mechanical sprayers.

Stir the paint thoroughly before use. When using large enough volumes, this procedure must be repeated periodically.

Since rubber paint for wood is usually applied in 2-3 layers, it is necessary to strictly observe the time interval between them recommended by the manufacturer.

Main manufacturers

Russian manufacturers of various paints and varnishes appreciated the advantages of the new protective coating and quickly mastered the development and production of such products. The most widely represented on the construction market are rubber paints for wood from Super Decor, Master Good, Baltikolor, Rezolux, Dali, LKM USSR, Technoprok.

Naturally, each trade mark applies its own individual "recipe" for manufacturing and technological features of production. However, everyone strictly adheres to the requirements to ensure the safety of people and the environment.

Varieties and prices

The color range of the currently sold formulations is quite diverse. For some manufacturers, the number of shades of finished products reaches 20. For those who supply products in basic white or light gray, you can either order a specific shade from the catalog, or purchase tinting pigments separately and start your own “design creativity”. It all depends only on personal preferences and time, which is sometimes so lacking for aesthetic experiments.

According to their purpose, such coatings can be divided into three main groups:

• universal (for application to walls and other wooden structures of various buildings);
• increased wear resistance (for floors and;
• highly specialized (for wooden vehicles on water).

The price of such products depends on the field of application, composition and manufacturer. Thus, a can (3 kg) of VD-AK-103 universal paint (base color) from Technoprok will cost 600-700 rubles. Approximately the same price for goods from Dali. But, for example, the same amount of finished colored products (for a similar purpose) from Super Decor (consumption 120-250 ml / m², full curing time - a week, technological break between layers - 1.5-3 hours) will cost 850- 950 rubles. Moreover, only imported components were used for its manufacture (according to the manufacturer's own statement).

Products from German Remmers, Spanish Lepanto or Canadian Liquid Rubber will cost much more.

For wooden boats, boats and yachts

• protection against aggressive influence of salt water;
• preventing the bottom from fouling with algae and microorganisms, which significantly reduce speed and increase fuel consumption;
• increasing adhesion when operating in high vibration conditions.

Due to the increased operational requirements, the price for such products is higher than for analogs for general construction use. Manufacturers engaged in the production of such highly specialized products: Norwegian Star Maling, Russian "Baltikolor" and "LKM USSR" and American Overton's and Totalboat.

Finally

Modern rubber paints for wood, user reviews who have already applied these products in practice, mostly only positive, fully correspond to the declared characteristics. Indispensable conditions that must be observed:

• when choosing - take into account the purpose of a specific product (for example, only for vertical surfaces, for floors or for boats and boats);
• when using - strictly follow all the manufacturer's recommendations, which are indicated on the packaging.

Protect the floor and walls carefully. The use of a waterproofing sealant will simplify the work and save time. Water will not be able to penetrate into wooden elements, and this will increase the period before renovation work in the house. What liquid waterproofing for floors and walls is more practical and more economical, we will talk in this article. Readers will learn how to apply liquid insulation and what equipment is used for this.

Liquid waterproofing has been used to protect the walls and floors of a wooden house for more than 15 years. During this time, the materials showed themselves only on the positive side. And the solidity of the coating makes the liquid material indispensable among other protective ones.
According to the application method, liquid insulation is divided:

All methods refer to the cold method, therefore, you do not need to use a burner or other heating equipment. This indicates the safety of the application. The most effective spray application using special equipment.
Of course, the equipment is not cheap, but labor costs are significantly reduced. The volume of work of 3 people is easily performed by 1 worker.

You can try to rent equipment in the rental of special instruments, but there it is found only in large cities. You can buy equipment for processing a house once, and the price for it will be worth all subsequent repairs.
Advantages of liquid waterproofing:

1. The protective layer is elastic.
2. Easily closes small cracks and crevices.
3. Resistance to mechanical and chemical influences.
4. Easily tolerates temperature extremes and UV rays without losing its properties.
5. Under mechanical action, it restores its primary shape by 95%.
6. There is no need to use gas and cooking heaters.
7. 85% of the waterproofing hardens within 1 hour.
8. It will last up to 25-30 years guaranteed.

Types of liquid protection of floors and walls from water

There are several different types of bituminous and bitumen-polymer based with various additives. But rubber and glass received the most reviews. Let's consider them in more detail.

Liquid rubber for protecting elements of a wooden house

Liquid rubber is suitable for waterproofing walls and floors, especially on the basement side. It has high hydro and sound insulation. The material has high adhesion to wood, and it is better to apply using special equipment. Therefore, most of the installation is carried out by professionals. The owner only needs to determine the grade of material needed for a particular job.

You can buy these brands in 200 liter barrels. For example liquid rubber Rapidflex, Technoprok.
There are varieties of liquid rubber that you can work with with a spatula or roller. these are applied by hand. You can buy these brands in 10 and 20 liter buckets, for example Technonikol or Slavyanka.

Liquid rubber is a bitumen emulsion diluted with water, therefore the material is environmentally friendly and has no extraneous pungent odors.

Specificity of application to the floor

The floor can be treated with liquid rubber from the outside and inside. But it should be borne in mind that the outer side treated with rubber will be black, so it is more advisable to use protection with subsequent coating, for example, laminate, linoleum or tiles.

Liquid waterproofing for the floor with rubber is applied in one pass with a thickness of 1-2 mm. The surface is pre-cleaned from dust and leveled. If this is not done before waterproofing, then in the future it will be necessary to break the solidity of the surface. Material consumption will be 3-4 kg / m².

Wall application

When treating the floor with rubber, it is necessary to waterproof part of the wall from the bottom by 20-30 cm. Such a scheme with rubber is especially necessary in bathrooms and kitchens, where the humidity is high and various leaks are possible. It is better to take the brands Elastopaz or Elastomix on the walls. The composition is applied manually, so you can do the waterproofing of the walls with your own hands. You can buy in containers of 10 and 18 kg, consumption 3.5 kg per m2 of wall.

The treatment of walls with rubber of the basement and basement premises is relevant. Moreover, liquid rubber can be used both on internal walls and on external ones. The material is applied at temperatures from +45 to -50 ° C, so work can be done at any time of the year.

More details on the processing of the floor and parts of the walls can be seen in the video:

Liquid glass to protect the elements of a wooden house

Liquid glass is a solution of water with potassium and sodium. By its action, waterproofing is penetrating. It does not create a film on the surface of walls and floors, but penetrates into the capillary system and solidifies there. This forms a dense inner layer that does not allow moisture to penetrate into the tree. In addition to its protective properties against water, the material has good antiseptic qualities. Such properties are given to it by sodium silicate and potassium solution. Sodium crystallizes in the wood and makes it resistant to moisture.

There are two types of similar glass:

1. Sodium.
2. Potassium.

Sodium is capable of interacting with other mineral compounds. Waterproofing with liquid glass is used to treat basement walls, foundations, and instead of antiseptics for wooden floors.

Potassium has a large crystallization and withstands various mechanical damage. It is advisable to use such a composition in wooden houses for treating walls and flooring.

Liquid glass technology

Before application, the glass composition must be diluted with water. To cover the floor and walls, when a wooden house is processed, a little composition will be needed, since the consumption of liquid glass is a maximum of 300 g per m2.

Floor insulation in a wooden house

To protect the cement screed, when a log house is being built, it is necessary to add liquid glass to the concrete mixture in a 1x10 ratio. Such a coating is used for screed floors of basements, garages, swimming pools.

If the floor is wooden, then the application technology is carried out with a brush or roller. The process resembles silicotisation. When applied, the material is quickly absorbed into the wood and creates a protective layer there. The floor can be processed inside the house and from the basement side. In this case, do not forget about the lags, which also need to be impregnated with liquid glass before laying. the composition is applied to the floor in 3 layers.

Wall treatment

The technology of application on the walls is not very different from the flooring with the help of a brush and a roller. For example, by covering the timber with liquid glass, you can fade small cracks after shrinkage, which will be difficult to caulk. It is convenient to cover walls not only in the house, but also in saunas and basements. The walls of the foundation are also often covered with a composition of concrete with liquid glass.

Before applying them to the walls, they must be leveled and, if this is an old structure, remove the paint or varnish. Then the surface is degreased with ordinary alcohol. For the deepest penetration of 15-20 mm, it is necessary to apply the composition in 2 layers. When processing walls from the street side, work can be facilitated using a spray gun. Inside, it is not recommended to apply the material to the walls in this way. When applying liquid glass, be sure to use protective equipment: respirators, gloves and goggles.

Price for various liquid waterproofing

You can buy liquid waterproofing at any hardware store. The price of formulations depends on several factors:

1. Brand, so TechnoNicol compositions are almost 2 times more expensive than Slavyanka.
2. Volume, so the composition in a barrel costs 1 kg cheaper than a 10 liter bucket.
3. Party, all manufacturing companies offer to buy in bulk.
4. The composition, various synthetic additives are not cheap and the price of waterproofing varies.
5. Impregnating compounds are several times cheaper than liquid rubber.
6. In the online store, the compositions are cheaper, since the seller does not need to overpay by hiring a large staff and renting a retail space.
7. You can buy cheaper waterproofing according to ads; many are putting up for sale the leftovers after the construction of their homes.
8. Import manufacturers offer to buy their compositions at an inflated price, since they enter the Russian market through several re-purchase sites.

The average price for waterproofing is shown in the table:

For greater efficiency, the floors and walls of the basement and the basement of the house can be coated with two compounds. First, it is applied to the cleaned surface with liquid glass and after it has completely dried, liquid rubber is sprayed. Such a cake made of liquid waterproofing is not afraid of even a flood.

For a simple country house, you can use cheap liquid glass, and for a private residential building, it is better to use monolithic rubber.

Floor waterproofing- an obligatory stage of the overhaul of the building, which protects the premises from moisture penetration. The use of specialized liquid solutions based on a combination of bitumen with polymers allows you to create elastic monolithic coatings that retain their unchanged strength after many years of operation. Due to the absence of any fumes waterproofing the floor in the house can be performed in closed rooms without danger for the performers.

Floor waterproofing services

The technology was developed at the turn of the century floor surface treatment with liquid rubber, the essence of which is to apply a bitumen-polymer emulsion to the surface, which, when solidified, forms a membrane that is absolutely insurmountable for water due to its complete tightness.

Spray-on waterproofing floor

For waterproofing floor with liquid rubber in large areas, compact and convenient Canadian equipment for spraying is used. The floor must be leveled and primed before applying liquid rubber. The primer, in addition to providing better application of the base emulsion, fills minor cracks and chips. After a short wait, the base layer of liquid rubber is applied.

Compared to bulk and paint coating methods, sprayed floor waterproofing it is distinguished by its ease of implementation and high productivity, which is especially important when processing large-sized surfaces. Mechanization of operations in combination with guaranteed filling of irregularities and cracks makes it possible to apply a universal method for processing smooth and curved surfaces.

Sprayed waterproofing concrete floor combines the advantages of a special protective composition and a universal technology for applying a moisture-proof material. Correct performance of operations is the key to successful processing of floor surfaces. Advantages of sprayed waterproofing:

• Simple application method;
• Filling irregularities, seams and cracks;
• Prompt hardening of the layer;
• Formation of a seamless monolithic coating;
• No need to warm up;
• Environmental safety of the coating;
• Lack of toxic secretions;
• Impermeable to water and steam;
• Perfect coating uniformity;
• Resistant to intense hydrostatic loads;
• Operational durability.

Floor waterproofing with application of the composition by means of cold spraying is a practical and absolutely safe technological process. The use of typical technologies is fraught with difficulties when processing uneven substrates. Sprayed waterproofing the floor in the house allows you to create an elastic coating that ideally fills in any irregularities and cracks. The rapid formation of a seamless, moisture-proof layer is the most important advantage of spraying liquid rubber onto treated floor surfaces.

Surface preparation

Waterproofing concrete floor begins with the preparation of the foundation. After removing dirt and moisture, the surface is covered with a primer. For the primer, one of the components of the bitumen-polymer waterproofing is used. The application of an emulsion without a hardener ensures the penetration of the material into the smallest pores and cracks in concrete with the formation of the thinnest bitumen-polymer film. For a high-quality result, it is necessary to prime all interfaces with the walls. The main layer is sprayed after the soil has completely dried.

An obligatory stage in the arrangement of floor coverings is the vapor barrier of the floor. It allows you to regulate the humidity in the room and reduce the negative impact of moisture on the structural elements of the building. Vapor barrier materials protect the insulation layer from getting wet and loss of thermal insulation qualities.

Why do you need a vapor barrier?

Do-it-yourself floor insulation from moisture

There is moisture in any room that negatively affects wooden structures. Vaporous moisture is a normal human waste product. It is released during cooking, washing, showering, etc. Steam has a high pressure compared to atmospheric air, therefore, being released, it begins to press on the surface of the walls, floor and ceiling, leading to the formation of condensation... Under this influence, wood begins to rot, and mold and mildew form on it.

The structure of the floor is also negatively affected by the moisture contained in the soil. As a result, it begins to slowly lose its performance and deteriorate. Insulation materials are filled with water and lose their heat-shielding functions. The floor becomes cold, and the house ceases to be comfortable and cozy.

A high-quality vapor barrier allows you to avoid these problems. A properly equipped vapor barrier helps protect wood and insulation, but at the same time allows them to breathe.

Vapor barrier materials

The vapor barrier of the floor in a wooden house can be made of various materials. Manufacturers offer an extensive range of them. The most common in wooden housing construction are film and membrane products. For concrete floors, the best choice is bitumen-polymer mastics, polymer rubber, etc.

Film materials

Film vapor barrier is easy to install. As a rule, perforated and non-perforated plastic sheeting is used to protect floors.

Perforated materials have a higher degree of vapor permeability, but in practical use this difference is hardly noticeable. It is very simple to lay the film, but it is easily damaged and quickly tears, therefore, during work it is necessary to be careful.

A variety of polyethylene films are materials with a reflective aluminum layer. They have higher vapor barrier characteristics, so they can be used for flooring in rooms with high humidity.

Polypropylene films, in contrast to their polyethylene "brothers", are characterized by strength and resistance to negative influences. On one side, a layer of viscose and cellulose is applied to the film. It is able to retain a large amount of moisture and thereby protect the floor insulation from condensation from the side of the film insulation. The film must be laid with a protective layer down.

Membranes

The highest quality, but also the most expensive vapor barrier material is diffuse membranes.... Unlike films, they have the ability to "breathe". The membrane can allow air to pass through, thereby regulating the moisture level. The material can be one- and two-sided, depending on whether air is passed from one or both sides.

There are no restrictions on the installation of the double-sided membrane. When arranging a vapor barrier using a one-sided material, you will have to keep track of which side in relation to the insulation it is laid on.

The main advantage of breathable membranes is the highest vapor permeability coefficient among all materials. It is achieved due to the special microstructure of artificial fibers from which this type of vapor barrier is made. In three-layer membranes, another layer is added, which is able to accumulate moisture in itself and gradually evaporate it.

The most expensive membranes combine hydro, steam and thermal insulation characteristics.

The device of the vapor barrier of the floor using this material provides the so-called "intelligent" regulation of the humidity level depending on the microclimate in the room.

It should be noted that one more important advantage of such materials is that they can be laid without a ventilation gap.

Liquid rubber

Liquid rubber for waterproofing the bathroom

This type of vapor barrier is used for concrete floors. When applied to the surface, the liquid rubber forms a seamless layer that resembles a thin film.

The resulting protective coating has heat, hydro, steam and sound insulating characteristics. The device for vapor barrier floors using liquid rubber is extremely simple. It is enough to apply the composition to the surface to be treated with a regular paint brush.

Arrangement of vapor barrier in a wooden house

Laying the floor vapor barrier should be at the stage of building a house. If it is necessary to equip the steam protection in the finished building, then a major overhaul will be required. The work is carried out in several stages.

Preparation

Vapor barrier of a floor in a wooden house fits on the subfloor. If the house is just being built, problems do not arise, and no special preparation is required. Laying vapor barrier materials at the construction stage is one of the stages of flooring.

In case of a major overhaul, it will be necessary to remove the floor covering and remove the heat-insulating layer. After that, the condition of the subfloor and the log is checked. All decayed or damaged elements must be dismantled and replaced. It is advisable to change the sagging boards of the subfloor. All structural elements must be treated with antiseptics and other protective agents.

Laying vapor barrier materials

Do-it-yourself floor vapor barrier

After completing the preparatory work, you can install the vapor barrier. Vapor barrier materials are placed on the subfloor. The joints between adjacent strips are sealed with a special tape.

You can fix the film materials with a stapler, but it is better to take adhesive tape. This method of laying allows you to fix the material without gaps. We must not forget that vapor barrier materials are mounted on a heater with a certain side, with the exception of double-sided diffuse membranes. The correct installation must be carefully monitored, otherwise the vapor barrier will not perform its functions.

Any insulation can be laid on the vapor barrier layer. On top of it, another vapor barrier is made. After sealing the joints of the second layer of vapor barrier, you can start arranging the finished floor and the final floor covering.

Liquid rubber for insulation of wooden floors

Vapor barrier of a wooden floor, as a rule, is made of film or membrane materials. They are easy to install and have high performance properties. Liquid rubber and other polymers are commonly used for concrete floors.

However, polymer and bitumen-polymer materials are quite suitable for vapor barrier wooden floors.... There are several types of liquid rubbers:

• For automated application.
• Hand applied.

Liquid rubber is an ideal material

The specific type of liquid rubber is selected based on the area of ​​the treated floor. You can lay a vapor barrier from this material in a private house manually using a regular brush. After complete drying, the polymers form a thin layer on the surface, which completely repeats its relief. This layer is practically impossible to separate mechanically.

Liquid rubber can be used on subfloors as it is black and must be covered with a floor covering. In general, it is quite easy to apply liquid rubber, but if construction skills are not enough, it is better to contact a specialist. After all, high-quality vapor barrier is the key to the durability of the entire floor structure.

Conclusion

Of course, you can do without a floor vapor barrier. But such savings will result in rapid damage to the timber elements and the need for complex and costly overhauls. The choice of high-quality and effective vapor barrier materials is huge, and choosing the right one is not difficult.
