Polymer waterproofing: variety of materials and features of choice. Modern polymer waterproofing is a reliable barrier to moisture in the bathroom Rules for applying polymer waterproofing

Polymer waterproofing is represented by compositions based on polymers (primarily polyurethanes), which are ideal for carrying out work to protect objects for various purposes from the destructive effects of moisture. Waterproofing with polymer materials is easy to apply on both horizontal and vertical surfaces. It effectively fills seams and joints and provides them with reliable protection from moisture penetration.

Polymer waterproofing of a foundation or other building elements involves polymerization of the applied composition upon contact with air. As a result, a plastic and very durable membrane is formed that can become a barrier to moisture.

Application

Polymer waterproofing materials are rightfully considered universal. They can be used for waterproofing:

residential and industrial premises;
structures made of concrete and reinforced concrete;
interfloor floor slabs;
rooms with high levels of humidity (toilets, showers, bathrooms, saunas, swimming pools).

Polymer waterproofing of floors and other objects is allowed on bases made of the following materials:

concrete;
brick;
plaster;
glass;
tree;
drywall;
zinc coated steel;
Styrofoam;
tiles.

Advantages

Polymer waterproofing for roofing and other building elements has good adhesion to plaster compositions and a variety of adhesives for tiling. It can also be used before laying linoleum and laminate. Of course, these are not all the advantages of polymer waterproofing. The rest are as follows:

excellent adhesion to different types of bases;
high plasticity, allowing to withstand deformations and distortions of building elements;
immunity to influence ultraviolet rays and temperature changes;
long service life, which ranges from 25 to 50 years;
ease of application, possibility of application both manually and with special equipment.

Not a single construction of a residential building or institution, not a single interior design is complete without the use of waterproofing. The wide range of waterproofing compounds offered will allow you to easily choose what you need. One of the widely used compositions is polymer waterproofing.

Peculiarities

Polymer waterproofing mostly consists of a bitumen emulsion, which includes latex particles. The choice of this waterproofing solution on the shelves of construction stores is huge. Composition may vary. The contents of the composition are directly influenced by the manufacturer and purpose of the solution.

Do not forget that a certain air temperature can affect insulating compounds. This provokes polymerization. As a result, a strong and viscous membrane is formed. Its characteristics satisfy all requirements in the process construction work.

Advantages and disadvantages

Use as insulation polymer base has many advantages. By correctly selecting the waterproofing composition and the specifics of its application, you will receive a surface with moisture-repellent properties.

In addition, there are a number positive aspects that are worth considering in more detail:

Today, up to 400% elasticity can be achieved from a polymer base.
The service life of the resulting waterproofing surface can range from 25 to 50 years.
Guaranteeing the possible ingress of water eliminates the formation of monolithic coatings in which there are no joints.
This material makes it possible to use it for any type of structure, including a complex or non-standard configuration, and even in the presence of relief.
Polymer waterproofing is one of the most durable compounds, which is unshakable to any kind of mechanical, chemical, ultraviolet and temperature (from -60 to +110 degrees) influences.

High wear resistance of the composition. The polymer base is characterized by the creation of a layer that subsequently does not become thinner, while remaining a reliable and uniform coating, regardless of the conditions and period of operation.
Economical consumption of material is achieved by the insignificant thickness of the coating of the polymer composition. This is quite enough to create durable waterproofing.
Creating adhesion with different materials such as concrete, metal or wood, as well as many different types finishing coating.
This waterproofing composition is easy to apply. In this case, it is possible to choose necessary technology application depending on the presence or absence of certain skills and knowledge.
The time required for the waterproofing composition to harden is minimal, which has a beneficial effect on the overall progress of construction work.
The absence of toxic fumes and toxic substances in the composition guarantees the safety and harmlessness of the polymer base.

The insulating coating is highly repairable. In other words, if any defect occurs on the surface of the polymer composition, it is quite easy to restore it. To do this, you will need to apply an additional layer to the existing one around the entire perimeter or in the required area.
The polymer composition has vapor permeability, which is one of the fundamental qualities in order to create a comfortable microclimate and protect certain building materials from the adverse effects of water.
A huge range of color shades of the polymer composition will allow you to use this composition as a finishing decorative material.

Like any product, a polymer waterproofing composition has disadvantages, of which its high cost can be particularly highlighted. The composition is much more expensive than its analogues, such as roofing felt and bitumen. But it is worth noting that the quality of the resulting coating fully justifies the high cost.

Recognizing the advantages and benefits of this option will allow reducing financial costs for additional renovation work and replacement of lower quality waterproofing coating.

Types and selection rules

A wide range of waterproofing polymer bases can confuse consumers, and therefore it is recommended to familiarize yourself in advance with the variety of insulating compositions offered by manufacturers.

There are several criteria to help you choose required material, meeting all your requirements and wishes:

Density. The consistency of waterproofing, which is based on a polymer solution, is usually divided into liquid and semi-liquid composition. It is worth noting that there is an alternative in the roll membrane format, which is not inferior liquid foundations, however, it is in little demand among consumers.
Function. Today the manufacturer is developing a huge the lineup for its signature line. Each product is necessarily produced with recommendations for application and an indication of the specific structural element of the structure for which it is intended (roof, floor surface, foundation or metal structures).
Components included. The elements used and their combination divide the polymer waterproofing composition into several types. The most popular today are cement-polymer and bitumen-polymer compositions.

Application technology. The application technology is influenced by several aspects, including the availability of experience with waterproofing work, the available time frame for completing the work, as well as the presence or absence of the necessary tools. In this connection, it is customary to divide it into the following types composition: coating polymer waterproofing, liquid, solution homemade(which is based on epoxy resin). Waterproofing polymer compositions produced for self-cooking, require strict adherence to the recipe, specified by the manufacturer. Also, do not forget that it is necessary to strictly follow the deadlines for working with the polymer composition, otherwise there is a high probability that the composition will harden while still in the preparation container. Such quick-hardening compositions will cost you less if the work is carried out by a person with special skills and knowledge necessary equipment. For self-execution For construction work, it is recommended to purchase a more expensive and ready-made waterproofing composition.

Waterproofing work using a polymer base is not limited to its intended purpose. For example, it is often used for above-ground and underground structures, hydraulic installations, and wet rooms. Elastic polymer-cement two-component waterproofing is most often performed in mixtures. Sprayed waterproofing also has good reviews.

Specifics of application

As when working with other waterproofing compounds, the process of applying polymers is carried out in several stages:

decide on the type of polymer composition that meets all your wishes and requirements;
make sure you purchase required amount mixtures;
prepare the surface for further finishing work;
treat all necessary structural elements with a polymer composition, following the manufacturer’s recommendations;
wait until the surface hardens completely.

Before proceeding with the actual waterproofing procedures, it is recommended to choose for yourself optimal technology application. To do this, it is necessary to assess the availability of experience or knowledge, budget, technical equipment and other factors characteristic of construction work.

So, there are two ways to apply polymer waterproofing:

coloring– to carry out this procedure, it is recommended to purchase a paint brush and roller in advance;
atomization– this technology will require an airless pumping unit.

The first application option is designed to perform waterproofing work for a spacious room or large structure.

When deciding to carry out the waterproofing process as quickly as possible, spraying technology will suit you. For correct execution process you need to follow a simple algorithm:

Prepare the airless pumping unit. Make sure fully equipped equipment.
Prepare non-concentrated calcium chloride. If you purchased a ready-made solution, fill the container with it.
Connect the container to the airless pump unit.
Also connect a container with a polymer composition for waterproofing.
Next, spray the mixture onto necessary elements structures or surface.
Make sure that when spraying, two containers are working simultaneously, since the compositions must be mixed.
Ultimately, you should get an even layer, the thickness of which will be from 2 to 4 millimeters (depending on the design configuration), so try to direct the stream in such a way as to achieve this result.

Budget option waterproofing will be using coating application technology. Using a similar method, you have the opportunity to waterproof High Quality small space or individual structural elements, while the consumption of the polymer composition will be minimal.

Let's take a closer look at the stages of waterproofing work:

Acquire and Prepare necessary tools. The choice in favor of a fine-pile paint roller or wide brushes will depend on what type of structure you are processing.
Dab the lint of the roller or brush into the waterproofing polymer compound.
Paint all necessary areas, trying to cover the surface so that the coating is two to four millimeters thick.
Wait until the surface is completely dry.
Repeat the procedure by applying another layer.

If it is important for you to obtain uniform and smooth surface, it will help to check the quality of the work done building level. Thanks to it, you will be able to identify all the defects that have arisen.

When using any material and, in particular, a waterproofing composition, it is recommended to prepare the base - the surface - in advance. To do this, you will need to mark areas that are more susceptible to moisture. It is worth noting that waterproofing is applied to the lower area of the wall surface and floor. They should be cleaned in advance of dust, cracked plaster and large irregularities, which are recommended to be smoothed before applying the polymer base.

All structural elements houses or apartments require reliable protection from high humidity. Why is waterproofing needed?

In a room located above damp basement, moisture destroys concrete floors. IN wooden covering High humidity causes mold to grow and rotting begins. IN multi-storey buildings on the middle floors, when moisture penetrates through cracks at the joints of the floor, carpet, laminate, parquet, bamboo lose their original appearance and become unusable.

Waterproofing the first floor of a private house that does not have a basement or floor in the country house will extend the life of the building. Water vapor rising from the ground can be acidic or alkaline.

Interacting with concrete, moisture can destroy it completely in a few years. Waterproofing the floor will help avoid such problems in your home, increase the safety of its operation, and improve comfortable conditions accommodation.

Materials

Depending on the purpose, conditions of use of the room, condition of the subfloor, financial costs, use various materials for waterproofing, which protect it from destruction. All types of waterproofing comprise two main groups - for external and internal work.

According to the main composition of the water-repellent component:

bitumen – based on mineral components;
polymer;
bitumen-polymer.

Based on the method of application to surfaces, the main types are distinguished:

roll;
film;
penetrating;
membrane;
painting;
pasting;
coating;
powder;
plastering.

Roll and self-adhesive waterproofing

They have become widespread for waterproofing floors in apartments and private houses. Roofing felt is still used for waterproofing today, along with roofing felt and glass roofing felt. Cardboard or fiberglass impregnated with a mixture of bitumen and basalt chips. They can be laid to protect foundations, roofs, and floors from moisture. Modern waterproofing materials have additional thermal insulation properties.

Roll waterproofing - membrane (geomembrane). There is a lock at the junction. Additionally, gluing is performed.

Rolled waterproofing materials come in two types: floating and self-adhesive. Floating materials are durable and inexpensive. Their disadvantage: the waterproofing must be installed using a gasoline or gas burner; when heated, they emit an unpleasant odor and harmful smoke. The method is quite suitable for use at the dacha with your own hands when waterproofing the subfloor. Laying roofing felt during waterproofing work requires the installation of an additional screed.

Self-adhesive waterproofing is installed quickly and is easily attached to the base. Which side to lay the self-adhesive material is indicated in the attached instructions. For waterproofing, a self-adhesive film made of polyvinyl chloride, polyethylene, and polypropylene is used. Usually pvc film used to create dry or cement-concrete screed concrete floor. Working with self-adhesive film does not take much time.

Penetrating waterproofing

used as a primary or additional measure to protect a concrete floor. Includes subgroups:

Concreting – increases the density and strength of the material. Placed as an additive to create a reinforcing layer.
Cement-polymer - used for treating concrete, wood, and brick floors. Polymer waterproofing has high adhesion to the surface, is easy to use, and environmentally friendly. Waterproofing the subfloor can be done with cement-polymer mastic laid on a reinforcing mesh - you get a waterproofing layer and a screed at the same time.
Cement inorganic waterproofing is used to treat concrete floors.

Ceramic tiles can be easily laid on a layer of penetrating waterproofing.

Mastics

plastic adhesive solutions based on bitumen, liquid rubber, polymers, resins, plasticizers, and other additives. Mastic solutions are of hot or cold type. Floor waterproofing mastic is used to create a waterproof layer and treat joints in the bathroom, toilet, kitchen, bathhouse, and swimming pool. Mastic displaces rolled materials, since, unlike them, it does not have unpleasant odor, does not form seams that could cause water leakage.

Water-repellent materials

For waterproofing, liquid water-repellent materials can be laid. The composition of the group includes primers, varnishes, paints, impregnations.

Powder materials

for protection against moisture, they are represented by a variety of dry mixtures based on cement, glue, binders, and plasticizers.

Immediately before use, add the dry mixture to the water so that the solution is ready for use. Powder mixtures are used to create flooring concrete screeds, waterproof layer of the floor of basements, swimming pools. It all depends on the chosen material.

Execution technologies

When applying waterproofing, it is important to follow the rule - in places where the floor meets the walls, the waterproofing layer must be raised to a height of at least 30 cm.

Application of liquid waterproofing. Liquid waterproofing for floors, depending on the composition and viscosity of the material, it is divided into cast and impregnating.

Polymers and bitumen compositions

Casting – application of polymer or bitumen solutions, which, when hardened, form an even waterproof film. Bitumen solutions are heated to a temperature of 130 - 140 ° C, poured onto a clean floor and leveled with a wide spatula.

This method is used to treat continuous bases before pouring the screed. Waterproofing can be laid in several layers, between which a metal reinforcing mesh or reinforced fiberglass is placed; The thickness of the waterproof film can be 5–15 cm. The base of the floor is impregnated with waterproofing material.

Surface coating involves working with heated bitumen-polymer mastics, cold polymer, rubber-epoxy mastics. Coating waterproofing based on oxidized bitumen, it is produced with the inclusion of an organic solvent and various fillers.

Used as additives crumb rubber, plasticizer, latex, which significantly increases the elasticity of the coating and prevents it from cracking. Bitumen-polymer mastics are characterized by high adhesion. Laying waterproofing under a concrete floor with reinforcing fiber significantly increases its strength and abrasion resistance.

A special primer applied before applying the mastic increases the bond of the waterproofing layer with the concrete base. Mastic can be sold complete with a primer; they have a common main component. Main advantages coating materials- economical, easy to apply.

Coloring

How to waterproof a floor by painting? Painting is used for floors along joists, for wooden or concrete covering. Polymer or bitumen varnish is used. Depending on the consistency of the composition, it is applied to the surface with a spatula, roller, paint brush. The layer with this treatment is 2 - 3 mm thick and additionally performs the functions of anti-corrosion and anti-fungal protection. The service life of such protection is 5 years.

Pasting materials

Self-adhesive roll-on waterproofing option

How to properly waterproof a floor using adhesive materials? This method involves laying rolls and sheets of moisture-resistant materials in layers on a previously cleaned and primed base floor.

Types of adhesive waterproofing:

Conventional flooring on a surface under a cement or dry screed, under a wooden rough covering with a joint or in an independent way fastenings
Fusing rolled material onto the floor gas burner. The method is fire hazardous and requires skills and strict adherence to fire safety rules.
Pasting with special adhesives and mastic. Many types of modern film waterproofing have an adhesive layer, which greatly simplifies their installation. The melting temperature of mastic on a bitumen-polymer base is selected 20 - 25 ° higher than high temperature air of this room.

All types of lining materials react to shear, and therefore they are used to protect rigid structures made of brick, concrete, and reinforced concrete from high humidity. This type of waterproofing is also used for wooden subfloors.

Plaster

Easy to implement, environmentally friendly safe way using various dry cement-based mixtures with the inclusion of mineral and binders polymer additives. The solution fills well any unevenness, cracks, or crevices of the surface being treated. The mixture is applied with a spatula or brush.

Mastic and plaster

Mastic for waterproofing floors. Features of working with mastic and plaster.

After applying the self-leveling material, the floor must be in a calm state for the composition to polymerize. The mastic is applied in several layers - in this case, each subsequent layer is applied perpendicular to the previous one after it has completely dried.

Complete waterproofing is ensured when the floor and walls are treated to a height of 10 - 15 cm. Cement-polymer mastics provide water protection and form a self-leveling surface. There is no need to fill the screed. A floor finishing coating is laid on top of the waterproofing.

Backfill materials

Backfill waterproofing is used to protect floors in wet areas. How to lay backfill material? Bulk components are poured into the pre-constructed formwork in an even layer.

Perlite sand, ash, mineral wool, and bentonite are used as fillers. Backfill hydraulic protection has a long service life, but its installation is a labor-intensive and expensive process.

Choice of premises

When choosing a material and method of waterproofing the floor, you need to take into account individual characteristics operation of the premises - humidity, presence of a “warm floor” heating system, presence of a toilet, swimming pool.

Work must be carried out especially carefully at the dacha in the garage - a constant excess of moisture will lead to rotting of vehicles. Which waterproofing to choose to protect your garage floor?

The optimal solution is concrete. Waterproofing under a concrete floor - penetrating, impregnation, additives to concrete when preparing the solution. Immediately before pouring concrete, the soil is filled with bitumen, construction clay is also used, or roll material- geomembrane.

It is possible to use a combined method of waterproofing - roll coating lay the first layer, then seal all the joints that appear and apply a layer of mastic on top.

Preparing for work

Before starting waterproofing work, preliminary measures are taken with the subfloor:

removal of old coating;
thorough cleaning and drying of the rough surface;
sealing cracks and cracked parts of the surface with waterproofing putty.

The main condition for the duration of operation and the effectiveness of preserving the floor from high humidity is right choice material, compliance with installation technology.

APPLICATION OF CEMENT-POLYMER WATERPROOFING TYPE

High-quality cement itself, to a certain extent, has waterproofing properties. However, the usual cement-sand mortar It is difficult to manufacture in such a way that there are absolutely no pores through which moisture penetrates. Special cement-polymer waterproofing compounds do not have these disadvantages.

The composition of cement-polymer mixtures includes three components:

Binder (astringent) - quality cement, ensuring the strength of the composition and largely repels water.
Filler - fine quartz sand.
Polymer additives. They provide increased adhesion of the composition to the base, penetrating deep into the surface of the concrete and crystallizing in its structure, firmly connecting the base with the applied coating. Increases the hydrophobic properties of the cement composition.

Cement-polymer compositions have a number of advantages compared to bitumen-polymer insulation:

They can (and even need to) be applied to a damp surface. The composition holds well not only on dry, but also on wet concrete. At the same time, the bitumen insulation will simply be torn away from the surface by the backflow of water (from inside the concrete).
The adhesion (adhesion strength to the surface) of cement (mineral) waterproofing is higher than that of bitumen-polymer. The compositions adhere perfectly to concrete, brick (including sand-lime brick) metal and wooden surfaces. Mineral insulation has high mechanical strength, abrasion resistant.
The surface treated with cement waterproofing can be finished two weeks after applying the composition without any additional training. Glue tiles, plaster, putty, paint - finishing materials adhere perfectly to mineral bases. Bituminous insulation will have to be covered with plaster over a mesh or screed. This is a huge plus in the manufacture of pool bowls and more.
Cement-polymer waterproofing has unique property: It is vapor permeable. That is, water will not penetrate inside the structure, for example, the base of a building, while the masonry, if it is moistened, will dry out. The occurrence of delamination is eliminated if moisture does not come from outside, but from inside the concrete; it will gradually be removed outside. Bitumen waterproofing in such cases the moisture comes off. Due to high vapor permeability, mineral insulation can be used specifically for internal waterproofing, and often this is the only possible solution during the reconstruction of buildings.
The compositions are chemically neutral, environmentally friendly, and approved for use in drinking water reservoirs.

Types of cement-polymer waterproofing. Based on their properties, we would divide cement-polymer waterproofing into three groups:

Standard mixtures that create a very abrasion-resistant outer coating. However, it is inelastic and if a crack occurs in the base (concrete), the waterproofing will also be damaged. And this, you see, significant drawback, since the probability of cracks appearing is almost one hundred percent!
Crystallizing mixtures (penetrating insulation) contain salt additives, which, when penetrated into concrete, form waterproof structures. Moreover, over time and as it gets moistened, the waterproofing “grows” more and more into the base and becomes more reliable. Such compositions are capable of covering small cracks(about 0.5 mm) in the base, they perfectly hold negative water pressure, do not allow water to pass through from wet concrete, which makes them indispensable for the reconstruction (draining) of underground structures where external waterproofing is missing or damaged.
Elastic cement-polymer coatings are intended for problematic bases in which cracks can form, and this is the majority concrete foundations performed today! Market-recommended brands are reliable, guaranteed to cover cracks up to 1 mm, and withstand vertical water pressure up to 50 m.

Polymer-cement compositionBitumsealFlexproduction plantBitumPetrochemicalIndustriesLtd. covers cracks of more than 2 mm! Thanks to latex added to hydraulic additives, the finished waterproofing coating BitumsealFleximparts unique elasticity.

Waterproofing technology

Before starting work, surfaces must be cleaned of dust, dirt and oils. In case of weak loose foundation, the manufacturer Bitum Petrochemical Industries Ltd. recommends pre-treating the surface with a two-component Aquapoxy penetrating primer.
The crumbling mortar and concrete are removed from the seams and cracks, cleaned and tightly caulked with any non-shrinking cement mortar Cracks, seams and large shells are embroidered and tightly filled with the same solution or hydraulic seal.
The surface must be moistened immediately before applying waterproofing.
In the corners and in the half-wall interface, first make fillets with a radius of 3-4 cm. For this you can use cement plaster. Additionally, strengthen the joints with waterproofing tape, embedding it into the material. Place an additional layer of Bitumseal Flex on top.
Coating compounds are applied only with a brush or spatula.
When applied manually cement mixture thoroughly rub or smear into the surface, leaving no gaps. Small shells are filled with the mixture.
To achieve the desired result, apply two or three layers. When applying the first layer, movements with the spatula should be in one direction. Each subsequent layer is applied at intervals of 12-24 hours. The next layer is applied in a direction perpendicular to the previous one. The applied layers of the mixture should be protected from drying out too quickly. To do this, the surface must be wetted every 2-3 hours for 1-2 days.
Internal prefabricated processing concrete walls basement is completed. After two weeks the surface can be protected tiled cladding, plaster or screed.

When carrying out internal waterproofing of basements and ground floors This is generally the only option.

The biggest danger for many building materials represent water and its evaporation, which accelerates their aging and destruction. To avoid this and extend the life of building materials and buildings made from them, waterproofing is widely used.

There is a wide variety of modern waterproofing materials, each of which has its own characteristics. One of them, widely known in Lately, is a polymer waterproofing. In most cases, it is based on polyurethane, to which furan, phenol-formaldehyde, urea and other resins are added.

Features of polymer waterproofing:

The scope of application of such waterproofing is very wide. It is used to protect above-ground and underground buildings and structures, hydraulic installations, roofing and floor coverings, walls, foundations, etc.

Moreover, all polymer waterproofing is divided into several categories:

Consistency

It can be liquid or semi-liquid, and according to its component composition – cement-polymer or bitumen-polymer.

Purpose

Directions for use

The first contains Portland cement and synthetic resins, additives and fillers. Ready composition It is a fairly plastic mass, similar to plasticine. One of the conditions for the durability of a waterproofing coating made of this material is the absence of particles of dust and debris (this must be carefully monitored during work).

The second is produced on the basis of oxidized bitumen with an organic solvent. In addition, various substances are added to the mixture to improve waterproofing characteristics. It is produced in the form of mastic, which is associated with some of the features of this waterproofing material. So, when drying, it forms an uneven surface, which must be covered on top with a screed (if the floor is insulated) or sheathed finishing material(on the walls).

Application of polymer waterproofing:

Most often, polymer waterproofing materials are used to treat dry surfaces, but there are also those that can be safely applied to wet ones.

However, most formulations are sold in dry form and must be prepared immediately before application. The main condition for this is maintaining the correct proportions and quickly applying the compositions, since the “lifetime” of many of them is only a few hours (and sometimes even minutes).

In addition, polymer waterproofing is, as a rule, very toxic and fire hazardous. Therefore, when working with them, it is important to strictly follow safety rules. True, at present, manufacturers are already producing practically harmless compounds that can be worked with in enclosed spaces.

Advantages of polymer waterproofing:

The indisputable advantages of this waterproofing material include the fact that it forms a continuous seamless fabric with high water-repellent properties.

It is durable (warranty is 25 years, but in practice this period is much longer). At the same time, the waterproofing layer does not thin out over time, and remains as smooth and durable as just after application. By the way, the service life of a cement-polymer coating is much longer than a bitumen-polymer coating.

Another advantage is that it is equally suitable for any structure - it can be easily applied even to complex and small, convex and concave elements. The type of surface on which the waterproofing is applied does not matter. It will go well with concrete, block, metal, wood and other types of coating.

Polymer waterproofing is not afraid of ultraviolet radiation, temperature changes, chemical effects of substances and mechanical damage (impacts, scratches, etc.).

It is also important that applying this material is quite simple. This does not require special qualifications or extensive experience. There is also a wide palette of colors.

The only drawback is most often the price of this type of waterproofing. However, as you know, the stingy has to pay more.

Rules for applying polymer waterproofing:

In order for waterproofing to fully demonstrate its advantages, it is necessary to first follow all the rules for its application.

Before starting waterproofing work, it is necessary to prepare the surface by removing all contaminants from it and eliminating unevenness. Some solutions and mastics also require preliminary wetting of the surface with water (these requirements, along with mixing proportions, should be indicated on the packaging). Only after everything preparatory work completed, you can start mixing the ingredients.

It is necessary to coat the surface evenly, paying Special attention“wet” places (where the greatest exposure to steam or water is expected). After applying the first layer, you need to let the insulation dry and then repeat the procedure.
