Liquid waterproofing for floors: a membrane with amazing properties. DIY liquid waterproofing of floors Liquid waterproofing materials for floors

Previously, solving the issues of protecting premises from the penetration or spread of moisture became a real problem. It was not easy to find the necessary materials on sale, and many technologies were known and available only to professionals. However, today, if you wish, you can find everything.

Waterproofing materials for floors are produced in various forms, and from this variety you can easily choose the most suitable one in terms of characteristics and application technology.

Much, of course, depends on what specific floor and what rooms need to be protected from moisture, since each of them requires a special approach. Therefore, before you go to the store and rush to spend money on waterproofing compounds, you need to familiarize yourself with each of them.

In addition to the floor material, which will be applied protective composition, when choosing, factors such as temperature conditions are also taken into account waterproofing premises and the floor of its location.

Today, there are several ways of laying or applying different moisture-proof materials - these are coating or plastering, painting, impregnation, pasting, casting, injection and backfill. In order for any type of waterproofing to give the expected effect, a very important condition is a well-prepared, cleaned surface on which it will be applied.

These materials are applied to floors using a roller, brush or spray, and are the most popular and used. Painting waterproofing agents create a thin hydrophobic film on the surface, with the composition penetrating into the structure of the material up to two millimeters deep. This happens thanks to additives from lime, talc, asbestos, which can close the pores waterproofing surface - brick or concrete.

Painting technology can easily be called the easiest to apply and affordable. To carry it out, materials based on polymers, resins, minerals, bitumen and other compounds with good adhesion and hydrophobicity are used. These can be polyurethane, rubber, epoxy compounds, silicone gels, acrylic or bitumen suspensions.

Sometimes they try to replace these waterproofing agents with thickened oil paint or varnish, but we must not forget about the special properties of the profile material, which conventional paint and varnish compositions cannot replace.

A separate group of painting waterproofing compounds includes sprayed ones, which are applied using spray guns. These suspensions are made on an acrylate base. These include, for example, such a well-known product as liquid rubber. This composition is applied in several layers and conscientiously performs protective functions for 40-50 years, and under the most unfavorable conditions of high humidity.

The application process is as follows:

  • the old coating is removed from the surfaces down to the base, then it is cleaned;
  • sealed thick concrete solutions discovered damage - cracks or chips, then leveled and dried well;
  • then the surface is impregnated with special primers or coloring compounds diluted 1:3;
  • after the soil has been absorbed, waterproofing compounds are applied;
  • some of them are slightly heated, but, for example, certain bitumen-based suspensions require heating even to 150-160 degrees;

  • For reliable waterproofing it is necessary to apply two layers of the composition. The first of them should have a thickness of about two millimeters, since it should be well absorbed into the surface being treated, and the second, control layer can be very thin;
  • Drying of each layer can take from one and a half to 15 hours.

Pasted waterproofing

The adhesive type of waterproofing is a sheet (roll) material that is laid out or glued with resins or mastics having a thick consistency to surfaces that require protection from moisture.

The material is produced in the form of rolls and sheets, they can be dense or thin, have a transparent, opaque or foil appearance.

  • Materials such as glass batt, roofing felt, metalloizol, folgoizol, technoNIKOL and the like are produced in rolls.
  • Waterproofing asphalt, polymer, bituminous materials and others with similar characteristics.
  • Membrane waterproofing, which has small rounded spikes on its surface, is also produced in the form of sheets and is well suited for laying under a screed.

It should be noted that protective materials are laid on the floor surface in different ways. But all forms of installation are quite simple, and bitumen or epoxy compounds are most often used for this process:

  • the adhesive mass is applied to the base. Some types of mastics must be heated before spreading;
  • on on When the composition is carried and, if necessary, heated, the cut roll material is applied, ensuring that each subsequent sheet overlaps at least how 10 cm;

When using roll materials, two layers are often laid, with the second oriented perpendicular to the first.

  • waterproofing in the form of panels is also laid overlapping or end-to-end;
  • each subsequent row of insulating panels is laid with a shift to the previous one in one direction or the other by half a panel (according to the brickwork system);
  • Any waterproofing laid on floors must extend 10-15 cm onto the walls.

Coating waterproofing

Coating waterproofing compounds have a thick consistency with very good elasticity. Such materials include thick bitumen and polyurethane mastic, polymer cement, etc.

These waterproofing agents contain fillers made of polymer fibers and plasticizers, which increases their adhesion and hydrophobicity.

These compounds are distributed on the surface in the same way as plaster solutions - using a spatula. The thickness of this seamless coating can range from 0.4 to 4 cm.

This type of waterproofing composition perfectly insulates the floors of such problem areas as balconies and loggias from moisture. ground floors and cellars, bathrooms and kitchens.

Mastics based on bitumen and polymers are applied not only in the technical rooms of constructed buildings, but also directly on the foundation slabs. It should be noted that hot coating applied in living rooms undesirable, as it is quite toxic and requires good ventilation during work.

TO coating waterproofing include and plaster look works using appropriate moisture-resistant compounds, which can additionally be applied to bitumen coating or simply to waterproofing cleaned surface.

The mixtures are diluted with water, applied with a spatula and evenly distributed over the surface. There can be two or three such layers, and each of them must dry well.

Plaster waterproofing in dry form resembles conventional plaster mixture or construction adhesive, but they contain special components that penetrate the pores of the material and close them.

Cast waterproofing

Cast waterproofing is divided into hot and cold, depending on the form in which it is applied to the surface. Apply hot to floors asphalt-polymer And asphalt composition- it can be pitch, hot bitumen or asphalt concrete.

For cast waterproofing to work effectively, the base underneath must be thoroughly cleaned and dropped.

Hot waterproofing

When laying this material, it must be heated to a temperature of 50 to 120 degrees, depending on the viscosity of the composition.

Bitumen is a natural material made from petroleum products, and pure form When it hardens, it will crack at any temperature. But its main advantage is water resistance and insolubility in water. Therefore, it is used as a basis for the manufacture of waterproofing compounds.

When heated, they are applied to clean surfaces in several layers.

Pitch is a product obtained by processing coal tar. There are several types of this material, they differ in melting point, usually in the range from 70 to 90 degrees. But this material is rarely used, and, mainly, it is used as an additive to other waterproofing compounds.

Cold cast waterproofing

This method of waterproofing is the most reliable of all existing ones, since it penetrates into every pore of the surface material without forming cracks. Most often, cold waterproofing is made from an epoxy mixture or liquid glass. This material is used today for the construction of self-leveling 3D floors, which at the same time serve not only as waterproofing, but also decorative design premises. This method of protection against moisture penetration is especially suitable for a bathroom that requires 100% waterproofing.

  • The epoxy mixture consists of two components - epoxy resins and a special solvent, which are mixed immediately before pouring and distributing it over the surface. The working composition is prepared in portions, as it sets quickly enough.
  • Liquid glass is an excellent waterproofing solution for cellars and rooms on the first floors. This composition will reliably protect the room from moisture penetration and will work no less effectively than a two-component epoxy mixture. The durability of such waterproofing can be determined by the service life of the entire structure, i.e. Having arranged it once, you don’t have to worry about repeating the procedure or repairs.

The material is environmentally friendly and does not emit fumes harmful to human health, and at the same time has excellent penetration properties into the most microscopic pores of concrete or other waterproofing basics.

Liquid glass is produced in dry and liquid form. Dry powder material is added to cement mortars, making them water resistant. It is possible to add the composition and liquid consistency to ready-made concrete - in this case the mixture is made in proportions per 10 liters mortar one liter of waterproofing agent.

Application of cast waterproofing

Any cast waterproofing is arranged as follows:

  • The surface is cleaned and dusted using a powerful construction vacuum cleaner.
  • Then the surface is repaired - cracks and defects in the base are repaired.
  • After repair work The floors need to be thoroughly dried.
  • Next are the floors primed. In each specific case, the composition of the soil will depend on the material that will subsequently be used for waterproofing work.
  • The waterproofing composition is prepared in accordance with the instructions attached to it, brought to the required consistency and poured in parts onto the surface.
  • Level the mixture using wide spatulas or a squeegee, then leave the surface to dry and harden.
  • Waterproofing may not be limited to one layer - two or three fills can be done, but after the final hardening of each previous layer.

Penetrating waterproofing

A penetrating type of waterproofing is applied to floors with an already installed screed. The compositions used in this case have the ability to penetrate the concrete structure and seal the pores, creating a moisture-resistant layer. The solution can be applied in several layers.

After reaching deep impregnation surfaces, the waterproofing must not be damaged by mechanical actions or perforations. Therefore, this type of material is very often used for protection basements and cellars. In addition to water resistance, this composition gives the concrete surface additional strength by creating special crystalline bonds intertwined with the structural crystal lattice of the cement and closing all pores in the base. These processes occur thanks to special silicate or lithium additives.

The penetrating mixture is applied to any smooth or uneven surface. surface - leveling It is quite possible to carry out the floor on top of it. It is necessary to take into account that each layer applied to the floor surface must be completely dry.

Injection waterproofing

For injection waterproofing Polyurethane one-component solutions with low viscosity are used. A chemical reaction in such compositions occurs when they come into contact with water - this contact leads to a significant expansion of the solution, an increase in its volume, and an increase in internal pressure. Such features allow him spread inside a concrete structure, displacing water and taking its place. The result is a waterproof polyurethane composition. Some of the materials used become elastic during a chemical reaction, while others take on rigid shapes. Bringing the composition used to a similar state occurs within 2 to 20 minutes.

Special equipment is used to carry out injection waterproofing. It can be carried out in combination with other measures, and is even suitable for conditionally mobile elements of the structure, for example, joints load-bearing walls and foundation.

But it should be noted that this process is quite expensive, both in terms of the price of materials, labor intensity and the use of special equipment. It is almost always accompanied by drilling additional holes for introducing the composition. In this regard, this option is usually used in extreme cases, when it is impossible to use other methods for emergency isolation of previously erected building structures.

Backfill waterproofing

There is the simplest and most affordable type of waterproofing, although it is quite labor-intensive - filling areas with water-impermeable bulk materials.

To carry out this process, materials of a powder, fibrous or granular consistency are used, such as waste, mineral wool, clay, foam granules, sand, etc.

For rooms with high humidity - cellars, semi-basements, basements, perlite sands are used mainly to protect the floor, which are considered universal material for waterproofing works.

Each layer of the poured composition must be well compacted, so the entire area of ​​​​the room is enclosed by walls (formwork), which will prevent the material from spilling beyond their boundaries.

On top of the compacted backfill should be laid concrete screed, which is arranged according to all the rules with reinforcement and alignment with beacons.

In addition to the materials described above, modern production produces a large number of other products, but, as a rule, they are not fundamentally different from those mentioned. In some rooms it is simply impossible to do without waterproofing, therefore, when choosing a material, as well as the technology for its application, you need to carefully consider all the characteristics of the compositions intended for this important process.

High-quality floor waterproofing will help make your home dry, warm and cozy. The modern construction market offers a huge variety of materials with which the floor can be protected from moisture. Liquid waterproofing products are very popular today, which create a seamless, reliable coating and penetrate even hard-to-reach corners of rooms.

All moisture protective products can be divided into 3 large groups: roll, mastic and liquid materials. The latter option is becoming increasingly popular today due to the following advantages:

  1. Firstly, liquid formulations features high elasticity. This means that they can be used even in a newly built house; after the building shrinks, the moisture-proof layer will not be damaged. Due to its flexibility, the material is able to withstand significant water pressure, reaching 25 atmospheres.
  2. Liquid waterproofing for the floor is not afraid groundwater, ultraviolet radiation and many other negative environmental factors.
  3. Such materials are environmentally friendly and can be safely used in residential areas.
  4. Unlike mastics, the component composition of liquid waterproofing does not contain volatile substances that evaporate during the drying process and reduce the thickness of the moisture-protective layer.
  5. Working with such substances is much easier than with rolled and mastic analogues. Liquid compositions are easily applied to the surface and penetrate even into hard-to-reach areas: corners, seams, crevices, etc.
  6. Absolutely any type of base can be covered with such waterproofing. Moreover, the membrane layer will protect the structure not only from water and moisture, but also from corrosion and temperature fluctuations.
  7. The drying time of the materials is very short.
  8. Despite the fact that the price of liquid floor waterproofing is relatively high, long term coverage service will justify all costs. In addition, you can apply the insulation yourself. Firstly, it is not at all difficult, and secondly, it will save on wages for hired workers.
  9. Liquid compositions can be used in any premises and in exterior finishing work.

Do-it-yourself liquid waterproofing of floors: types of materials and methods of applying them

Hot waterproofing

This type of work involves the use special materials, heated to high temperature. There are 2 types of hot insulation: asphalt-polymer and asphalt. Substances that are used in this case are bitumen, asphalt concrete or pitch. After hardening, the materials acquire good elasticity, strength, and bending resistance. The coating is durable and reliable, although it is not often found in apartments. Hot cast waterproofing is mostly used in private homes.

The work of applying hot bitumen to the base can be described in the following sequence:

  1. First, all debris, dust and other contaminants are removed from the floor.
  2. The surface is then carefully inspected for defects. Joints between slabs, cracks, crevices and other recesses must be sealed with sealants.
  3. The floor is left until it is completely dry. To speed up this process, they often resort to high-power heating devices, for example, they use infrared heaters or gas burners.
  4. The dried surface must be primed. For this purpose, hot bitumen is used, which is applied to the floor in a thin layer.
  5. If the waterproofing will cover only part of the room, work area separated from the rest of the area using formwork.
  6. When preliminary work completed, the selected material is heated to desired temperature. As a rule, such information is indicated on the product packaging.
  7. Then the heated composition is poured onto the surface and distributed with a squeegee, forming an even layer.
  8. The hot composition is allowed to harden completely.
  9. If you need to make several layers, after the material has hardened, it is covered with another portion of hot bitumen and the surface is leveled in the same way with a squeegee.

Cold waterproofing

You can protect the floor from water and moisture using cold cast waterproofing. The materials used for such work can be divided into 2 main types: liquid glass and liquid rubber.

Liquid rubber is a material that is made on the basis of bitumen and includes various polymer additives. These additives give the finished coating greater elasticity, wear resistance, strength and durability. Calcium chloride is added to bitumen-polymer mixtures - it reduces the density of the substance and makes it possible to apply insulation by spraying. When adding calcium chloride to liquid rubber, it is first diluted with water in a ratio of 1:10, after which it is mixed with the other components.

You can work with liquid rubber only at a temperature of at least 3 °C and on a carefully prepared base. Since the material is available in different consistencies, there are several ways to apply it:

  1. The pouring method is considered the simplest and fastest. To implement it, you do not need special equipment, and when liquid rubber is poured onto the floor, it fills all the pores, crevices and cracks. The finished coating is even and smooth.
  2. Liquid rubber can be applied by spraying, but to implement this method you need to acquire special equipment. The coating created by spraying material onto the surface is of the highest quality, since the substance is fed under high pressure and fills even the smallest pores.
  3. Applying rubber using a coating method is the most affordable and common option. To waterproof the floor in this way, you should purchase a material with a paste consistency.

Let's consider the benefits liquid rubber as a water repellent:

  • this composition adheres well to any surface;
  • he is not afraid of aggressive actions chemical substances;
  • the water-repellent layer is seamless, moisture will not seep through it anywhere;
  • Even old floors can be waterproofed with liquid rubber, they just need to be properly cleaned;
  • rubber has good elasticity, it is not afraid of shock loads and temperature changes;
  • it does not have a strong odor, is environmentally friendly, and is suitable for use in enclosed residential areas;
  • the material has a long service life.

The technology of waterproofing floors with liquid rubber can be described in the form of the following stages:

  1. First, the work surface needs to be prepared. To do this, the floor is leveled, cracks, chips, dents and other depressions in it are covered, and the protrusions are cut off and sanded. Then the base is cleaned of dust, dirt and debris.
  2. Then the surface is opened with a primer. To work with liquid rubber, it is better to use a primer similar in chemical composition to the waterproofing material. Such a product can be a polymer-bitumen solution, which will ensure good adhesion of the material to the floor. It is most convenient to apply the primer with a large brush or roller, after which it should be given time to completely dry.
  3. The next stage is coating the surface with liquid rubber. If waterproofing will be carried out by spraying, you need to acquire a compressor unit. Containers are connected to such a device, one of which contains a bitumen solution, and the other contains calcium chloride. In the process of working in compressor unit both substances enter simultaneously, which are sprayed onto the floor under high pressure and create a durable elastic film.
  4. If liquid rubber is applied using the pouring method, then simply pour the required amount of solution onto the prepared surface and then level it with a squeegee. After this, they go over the floor with a needle roller to remove air bubbles from the thickness of the material.
  5. The substance hardens for about two days, when the floor is ready, you can begin laying the finishing materials.

When covering the floor with liquid rubber, it is advisable to also treat the lower part of the walls, water pipes and pipes.

The second means for cold waterproofing is liquid glass. In its consistency, the substance resembles the previous analogue, but the glass contains other components: soda, potassium or sodium silicate, as well as quartz sand. Waterproofing the floor with liquid glass has many advantages:

  1. This material has antiseptic properties, which means that fungi and mold will not grow in the room.
  2. The treated surface has excellent water-repellent characteristics. In addition, it turns out smooth and seamless.
  3. Another advantage of liquid glass is its antistatic properties.
  4. The material not only protects the floor from moisture and water, but also gives the concrete additional hardness and strength.
  5. Good adhesion and the ability to penetrate into the smallest pores of the base should also be considered among the advantages of this product.
  6. Liquid glass can be applied not only to concrete, but also to wood.
  7. Often, a waterproofing agent is added to liquid concrete to improve its water-repellent characteristics.
  8. The undeniable advantages of this material can be considered its affordable price and economical consumption.

Let's consider some of the disadvantages of liquid glass:

  1. A layer of such waterproofing requires mandatory arrangement decorative covering, otherwise the glass will break within 5 years.
  2. The material is not used for application to brickwork, because he spoils it from the inside.
  3. Glass is a fragile material that does not withstand impact loads well. This reason confirms the need for a finishing coating.
  4. You need to work with this product quickly, since the composition hardens in a matter of minutes.

Let us describe in detail the process of using liquid glass as a water-repellent material:

  1. Liquid glass is used in two ways: as an impregnation for already hardened concrete and as a component of a fresh cement-sand mixture. In the first case, the consumption of the substance will be approximately 150-250 g/m². The glass is diluted with water to the desired consistency, after which it is applied to the surface in 3 layers. Thus, the composition penetrates into the pores of concrete to a depth of 10 cm and creates a waterproof layer.
  2. When adding the product to liquid concrete, it is added to the solution in a ratio of 1:8 or 1:10. Subsequently, concrete is used as a waterproofing agent, applying it to the floor using a coating method.

Penetrating waterproofing

Liquid waterproofing of the floor can be done using impregnating materials. They fill all the pores and openings on work surface, penetrating into its thickness to a considerable depth. A floor treated in this way becomes durable and waterproof; cracks and efflorescence do not form on it.

The construction market offers consumers a wide variety of penetrating waterproofing products; we will consider one of them - the Penetron mixture. This product is a combination of cement, quartz sand and special chemical additives. Penetrating into the pores of concrete, Penetron crystallizes inside and creates waterproof barriers. The penetration depth of the substance reaches 50 cm, which is considered a very high indicator. Before applying the product, the floor is thoroughly moistened, and the better it is moistened, the faster and more active the crystallization process will occur.

"Penetron" is sold in the form of a powder with a homogeneous structure that does not contain impurities or lumps. Before use, this powder is diluted in water according to the instructions. The mixture is then applied to the surface and allowed to dry. “Penetron” begins to set 40 minutes after dissolving in water, and finally hardens after 3 hours. Start off finishing flooring can be done no earlier than 14 days after waterproofing the floor with this material.

The surface coated with such a product becomes stronger, acquires waterproof qualities and is not afraid of the effects of acidic and alkaline chemicals. Penetrating impregnation does not waterproof brick and masonry, as well as foam concrete and wood. Such compositions are applicable only for moisture protection of concrete foundations.

Wood (a universal 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. Relatively recently, rubber paint for wood has appeared on the construction market due to its unique composition free from these shortcomings. High consumer and technical indicators contribute to its growing popularity, especially in individual construction.

Features of the composition

The term "rubber-based paint for wood" is not entirely correct in relation to this protective coating. Rather, it determines the properties and technical indicators of this product. In fact, the latter consists of:

  • acrylic - the main synthetic polymer binder that forms protective film on the treated surface;
  • latex, which is obtained chemically from artificial rubber (it is this that 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 environments(salts, alkalis and the like);
  • antiseptic components that prevent the formation of fungi and mold.

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

Main characteristics

Rubber paints for wood are characterized by:

  • waterproof;
  • high resistance to daily and seasonal temperature changes;
  • good adhesion with 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 for up to 10 years or more);
  • high elasticity;
  • good vapor permeability (which has a beneficial effect on the “breathing” properties of wooden structures);
  • high mechanical strength and abrasion resistance (especially rubber for wood);
  • increased anti-slip properties (which significantly increases safety when using, for example, stairs);
  • resistance to negative influence ultraviolet radiation (the coating does not change color for a very long time);
  • fairly economical consumption at high layer density (although this figure is higher than that of traditional analogues);
  • ease of application;
  • high drying speed;
  • possibility of application to cracked surfaces (without prior putty);
  • lack of odor;
  • simplicity further care using any household detergents.

Flaws

It is unlikely that you will be able to find at least one product on the modern market of high-tech and innovative building materials that does not have any disadvantages. Likewise, rubber paint has them, although there are very few of them:

  • the treated surface will be matte (a glossy shine cannot be obtained due to the components included in the composition);
  • the price of such coatings is higher compared to standard (alkyd, acrylic or oil) compositions.

Application area

Rubber paint on wood for exterior use is successfully used when arranging a protective coating:

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

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

Surface preparation

Naturally, the most optimal solution arranging a protective layer - applying rubber paint for wood outdoors on new or recently built buildings and structures. Pores building material not yet clogged with dust, dirt or other foreign matter. Durability will only benefit from this.

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

Application method

Almost all manufacturers of rubber wood paints for outdoor use recommend the following conditions for carrying out work, compliance with which will ensure the preservation of the protective properties of the coating during the warranty period:

  • The ambient temperature should be in the range from +5° to +30°C (the interlayer and final drying time indicated on the packaging is usually for +20°C).
  • Humidity - do not exceed 80%.

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

Before use, the paint must be mixed thoroughly. When using sufficiently large 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 paint and varnish products appreciated the advantages of the new protective coating and quite quickly mastered the development and production of such products. The most widely represented on the construction market rubber paints for wood from Super Decor, Master Good, "Balticolor", Rezolux, Dali, "LKM USSR", "Tekhnoprok".

Naturally, each brand uses its own individual “recipe” for manufacturing and technological features production. However, everyone strictly adheres to the requirements to ensure the safety of people and the environment.

Varieties and prices

The color range of compositions currently sold 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 separately tinting pigments and engage in independent “design creativity.” It all depends only on personal preferences and time, which is sometimes so lacking for aesthetic experiments.

Based on their purpose, such coatings can be divided into three main groups:

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

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

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

For wooden boats, boats and yachts

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

Due to increased operational requirements, the price of such products is higher than their analogues for general construction use. Manufacturers producing such highly specialized products: Norwegian Star Maling, Russian Balticolor and LKM USSR, and American Overton’s and Totalboat.

Finally

Modern rubber paints for wood, reviews from users who have already used these products in practice are mostly positive, and fully correspond to the stated characteristics. Preconditions 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 manufacturer's recommendations indicated on the packaging.

Vapor barrier of the floor remains an obligatory stage in the installation of floor coverings. It allows you to regulate the humidity in the room and reduce the negative effects of moisture on structural elements building. Vapor barrier materials protect the insulation layer from getting wet and losing its heat-insulating qualities.

Why do you need a vapor barrier?

Insulating the floor from moisture with your own hands

In any room there is moisture that negatively affects wooden structures. Vaporous moisture is a normal product of human activity. It is released when cooking, washing, showering, etc. Steam has higher pressure compared to atmospheric air, therefore, when released, it begins to put pressure on the surface of the walls, floor and ceiling, leading to the formation of condensation. Wood under such influence begins to rot, and mold and mildew form on it.

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

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

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

Film materials

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

Perforated materials have a higher degree of vapor permeability, but in practical use this difference is hardly noticeable. Laying the film is very simple, but it is easily damaged and breaks quickly, so you must be careful while working.

A type 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, unlike their polyethylene “brothers”, are characterized by strength and resistance to negative impact. On one side, a layer of viscose and cellulose is applied to the film. It is capable of retaining a large amount of moisture and thereby protecting the floor insulation from the formation of condensation from the film insulation side. You need to lay the film protective layer down.

Membranes

The highest quality, but also the most expensive vapor barrier material are 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 single- or double-sided, depending on whether air is passed through on one or both sides.

There are no restrictions on laying a double-sided membrane. When installing a vapor barrier using a one-sided material, you will have to pay attention to which side in relation to the insulation it is laid.

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

The most expensive membranes combine hydro-, steam- and heat-insulating characteristics.

A floor vapor barrier using this material provides the so-called “intelligent” regulation of humidity levels depending on the microclimate in the room.

One cannot fail to note another important advantage of such materials - they can be laid without a ventilation gap.

Liquid rubber

Liquid rubber for bathroom waterproofing

This type of vapor barrier is used for concrete floors. After application to the surface, liquid rubber forms a seamless layer resembling a thin film.

The result protective covering has heat, hydro, steam and sound insulating characteristics. The installation of a floor vapor barrier using liquid rubber is extremely simple. It is enough to apply the composition to the surface to be treated using a regular paint brush.

Arrangement of vapor barrier in a wooden house

Floor vapor barriers should be installed during the construction phase of the house. If it is necessary to install a vapor barrier in a finished building, a major overhaul will be required. The work is carried out in several stages.

Preparation

Vapor barrier of the floor in a wooden house laid on the subfloor. If the house is just being built, there are no problems and no special preparation is required. Laying vapor barrier materials at the construction stage is one of the stages of floor arrangement.

During major renovations, it will be necessary to remove the floor covering and remove heat-insulating layer. After this, the condition of the subfloor and joists are checked. All rotten or damaged elements must be dismantled and replaced. It is advisable to replace sagging subfloor boards. All structural elements must be treated with antiseptics and other protective agents.

Laying vapor barrier materials

DIY floor vapor barrier

After preparatory work you can install a vapor barrier. Vapor barrier materials are located on rough floor. The joints between adjacent strips are sealed using a special tape.

You can fix film materials using a stapler, but it is better to use 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 the insulation with a certain side, with the exception of double-sided diffuse membranes. 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 is another vapor barrier layer. After sealing the joints of the second layer of vapor barrier, you can begin arranging the finished floor and finishing floor covering.

Liquid rubber for insulating wooden floors

The vapor barrier of a wooden floor is usually 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 barriers wooden floors . There are several types of liquid rubber:

  • For automated application.
  • Applied by hand.

Liquid rubber is the ideal material

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

Liquid rubber can be used on subfloors as it is black in color and must be covered floor covering. In general, applying liquid rubber is quite simple, but if construction skills are lacking, it is better to turn to specialists. 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 device. But such savings will result in rapid damage wooden elements and the need for complex and expensive major repairs. The choice of high-quality and effective vapor barrier materials is huge, and choosing the right one is not difficult.
