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:

1. 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).
2. 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.
3. 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.
4. 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.
5. The compositions are chemically neutral, environmentally friendly, and approved for use in drinking water reservoirs.

Types of cement-polymer waterproofing. By 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, the cement mixture is thoroughly rubbed or smeared 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 use of high-quality waterproofing materials selected in accordance with operating conditions increases reliability and reduces the cost of maintenance and repair of buildings, highways, engineering infrastructure facilities and utilities. Therefore, polymer waterproofing, which is sold by the MPKM company, is in demand and is widely used in the construction industry.

Depending on the range of tasks being solved, elastic polymer waterproofing can be used as an independent waterproofing material or additional remedy, which increases the reliability of other methods for ensuring the waterproofness of concrete. Various brands and compositions for polyurethane based can protect building structures not only from water, but also from chemically active and aggressive substances, the impact of which causes the destruction of reinforced concrete structures.

Advantages of polymer waterproofing

The effectiveness of waterproofing materials containing epoxy resins and polymer additives, is due to the chemical resistance, durability and elasticity of the film that is formed during application protective compounds on the grounds.

• Elasticity allows partial compensation of base deformations, therefore polymer film waterproofing always remains intact and airtight.
• Polymer-based materials have good adhesion to concrete, brick, cement plaster, tiles, metal and other materials. They can be applied to absorbent and non-absorbent substrates. The waterproofing layer can serve as a base for shotcrete or finishing materials.
• Polymer waterproofing of concrete allows you to process surfaces of complex shapes. The coatings exactly follow the contours of the base and do not have seams that reduce the effectiveness of protection.

Polyurethane-based materials are very technologically advanced. They are quickly applied to previously prepared substrates: liquid polymer waterproofing using spray guns or special equipment for spraying two-component compositions, and paste mixtures using ordinary brushes, brushes and rollers.

Supply of polymer waterproofing materials

In the MPKM online store, wholesale prices for construction chemicals, Sika, and other manufacturers with fast delivery products to all regions of Russia. Technical support staff provide free consultations on the selection of polymer waterproofing for floors, walls, foundations, technical tanks and other tasks. Advice from an experienced specialist will help you buy waterproofing materials that are optimally suited for certain operating conditions and correspond to the characteristics of a particular facility.

In the recent past for protection building structures used for moisture bituminous materials. They did not provide sufficient reliability and their service life was limited. Now a more effective alternative has appeared - elastic polymer waterproofing. Let's talk about its properties and application features.

What is polymer waterproofing?

The category of polymer waterproofing includes a wide range of materials with a diverse composition, physical and chemical properties. But they all contain high-molecular compounds - polymers, which give them special characteristics. The method of application is also common: most of these compositions are intended for coating insulation. Most common polymer materials on a bitumen and cement base.

Advantages of polymer waterproofing

There are many polymer-based formulations, and they all have different positive qualities. But in general, we can highlight the following advantages of using this type of insulation.

• High degree of moisture protection. For example, in the case of cement mixtures, the addition of polymer components helps solve the problem of pores through which moisture can seep. Polymer waterproofing forms a continuous waterproof layer, while the base retains the ability to pass air.
• Good adhesion to the surface being treated. For each type of building materials you can find the appropriate composition. For example, waterproofing brickwork best done with polymer cement mixtures, and bitumen-polymer mastics are also suitable for concrete. Unlike roll coverings, the water-repellent layer obtained using these materials is inseparable from the surface.
• Resistant to any weather factors (temperature changes, ultraviolet radiation, precipitation), water pressure, and aggressive chemicals. This allows the use of polymer insulation for both internal and external work, including for the protection of buried structures.
• Elasticity. For some types of materials it reaches 400%. Thanks to this, polymer-based waterproofing is strong in tension and bending, and can withstand deformation loads well (including during soil movements and thermal expansion of structures).
• Polymer waterproofing fits well on any surface
• Flexibility. Elastic coating compositions can be applied to surfaces with any relief; they are easy to use in hard-to-reach places.
• Fluidity characteristic of many types of polymer waterproofing. The composition, which is almost equal in viscosity to water, fills even invisible pores and microcracks. This ensures absolute waterproofness.
• Long period of operation. While conventional bitumen coatings age, dry out and crack over time, polymer-based materials last an average of 25 years.
• Wear resistance. Even with prolonged use, the waterproof membrane does not lose its qualities, does not wear out or become thin.
• Economical. Material is applied thin layer and does not require much consumption.
• Safety, absence of toxic components in the composition.

What types of polymer waterproofing are there?

Materials are classified according to different criteria: by composition, by purpose, by method of use. Below we will discuss the main types of elastic polymer waterproofing.

Polymer-based insulation can have different consistencies.

As a solution consistency

Polymer-based elastic coating compounds are a ready-to-use mixture or require dilution (with water or a special liquid). The result is a solution of varying degrees of viscosity - from liquid to paste.

For appointments

Polymer waterproofing has a wide range of applications, which is due to the variety of materials and their universal characteristics. Manufacturers are striving to expand their product lines by producing mixtures for various purposes. Some of them are used for roofing work, others are used to protect the foundation from groundwater, others - for the floor, etc. Also, depending on the purpose, mastics and sealants are distinguished. The first are intended for large-scale work, the second - for sealing cracks, seams and other areas of local violation of the hydraulic barrier.

In the form of component composition

In terms of composition, polymer waterproofing is represented by two in large groups- materials based on bitumen and cement. The most commonly used additives are polyurethane, acrylic, epoxy resins, rubber, and mineral components. With their help, mixtures are given required properties: plasticity, fluidity, frost resistance, ability to quickly harden, etc.

In the form of application methods

The technology for installing elastic polymer waterproofing depends on the consistency of the solution. Viscous compositions are applied with a spatula, semi-liquid and liquid - with a brush or roller, as well as by spraying. Depending on the scale of work, the experience of the master and availability professional equipment manual or mechanized method is used.

It is also important to take into account the peculiarities of preparing the mixture. One-component polymer insulation ready for application, two-component compositions mixed in the proportion recommended by the manufacturer. Polymer cement mixtures are supplied in powder form, which must be diluted with water.

Where is polymer waterproofing used?

Elastic polymer insulation is often used to protect roofs.

Polymer-based waterproofing is used almost everywhere in cases where it is necessary to protect structures from the destructive effects of moisture. The main area of ​​application of materials is construction. They serve to protect the above-ground and underground parts of buildings:

• roofs;
• walls (inside and outside);
• foundations;
• basements and ground floors;
• rooms with high levels of humidity (bathrooms, toilets);
• balconies and loggias.

Also, with the help of elastic polymer waterproofing, garages, parking lots, swimming pools, reservoirs, bridges, roads, and hydraulic structures are protected.

Existing application methods

When choosing an application technique, first of all, the volume of work is taken into account. In private construction and renovation, they usually deal with small areas. To install polymer insulation in this case, you need the simplest tools - a paint brush or roller. The viscous composition is applied with a construction spatula. These works can be performed independently, without the involvement of professional labor.

Liquid insulation is applied by spraying.

In industrial construction, as a rule, a mechanized installation method is used. Liquid mixtures are sprayed airless using a pump unit.

Technology of applying polymer waterproofing

Elastic polymer waterproofing is generally easy to use, but to obtain a high-quality result, you must strictly follow the technology. The process can be divided into several stages.

• Selection of material. In this case, the properties of the treated surface should be taken into account, technical condition structures, operating conditions, factors external environment. Often, professional advice is needed for proper selection.
• Calculation required quantity mixtures based on consumption data and insulated area.
• Surface preparation.
• Preparation of the solution, if necessary according to the technology.
• Application of the composition.

When working with some materials, you need to wait until the waterproofing fully develops its properties.

Material selection

When selecting a material, you should focus not only on its characteristics, but also on the manufacturer. The important criterion here is the ratio of price and quality. If the budget is not limited, it is recommended to pay attention to the products of well-known brands that have long established themselves in the market. Russian market. Bitumen-polymer mastics are produced under the brands TechnoNikol, Bitumast, Ecomast. Among the cement mixtures, the products of the brands Ceresit, Osnovit, Lakhta, Mapei are well known. Among epoxy-based materials, it is worth mentioning Masterseal from BASF and the more affordable domestic brand Blokada.

Calculate the solution consumption used

Polymer insulation is applied in a thin layer.

The calculation of the material depends on its consistency. Liquid waterproofing polymer-based coatings are applied in a thin layer, so less solution is required to achieve the desired result. The exact data is indicated by the manufacturer on the packaging, but the average consumption is 1 kg per 1 m2 of surface. This implies that the material is applied in one layer with a thickness of no more than 2 mm.

Preparatory work

Before applying elastic polymer waterproofing, you need to carefully prepare the base: the quality of adhesion of the material to the surface depends on this. The work is carried out in stages:

• the base is cleaned of debris and dust;
• remove irregularities, protrusions, sagging concrete, smooth out sharp corners;
• if necessary, the surface is leveled with cement mortar;
• remove dust again;
• apply a primer or primer.

Spraying waterproofing

An airless spraying unit is used to apply insulation.

Elastic polymer waterproofing is applied using an airless spray system. Contact with air is unacceptable, since this will cause the mixture to harden prematurely. Although it is possible to rent a pump, it is best to leave the spraying job to those who know how to handle it. Moreover, some materials are demanding when choosing equipment, and not every installation is suitable for their application.

Before spraying the polymer waterproofing is reinforced weak spots surfaces. These are primarily corners, joints and junctions of structures. Geotextiles are used for reinforcement.

Two-component polymer waterproofing is mixed during the application process. Containers with compounds are connected to pumping unit. When spraying, make sure that the contents of both tanks are used evenly.

The polymer base used in coating waterproofing

Viscous polymer materials are not suitable for spraying; they are applied in another way. Such elastic waterproofing is called coating. Its installation is carried out manually, without the use of special equipment.

When using dry cement powder, the solution is prepared immediately before application in an amount no greater than can be consumed in one hour.

Conclusion

Polymer waterproofing is an effective and durable protection of any surfaces from moisture. Depending on the properties of the base, materials based on cement or bitumen are chosen. Before using the composition, carefully read the instructions.

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 range of models for its branded line. Each product is necessarily produced with recommendations for application and an indication of the specific structural element 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 in advance paint brush and roller;
• 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:

1. Prepare the airless pumping unit. Make sure fully equipped equipment.
2. Prepare non-concentrated calcium chloride. If you purchased a ready-made solution, fill the container with it.
3. Connect the container to the airless pump unit.
4. Also connect a container with a polymer composition for waterproofing.
5. Next, spray the mixture onto necessary elements structures or surface.
6. Make sure that when spraying, two containers are working simultaneously, since the compositions must be mixed.
7. 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.

A budget option for waterproofing will be the 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:

1. 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.
2. Dab the lint of the roller or brush into the waterproofing polymer compound.
3. Paint all necessary areas, trying to cover the surface so that the coating is two to four millimeters thick.
4. Wait until the surface is completely dry.
5. 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.

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.
