Cement-polymer mixtures. Polymer waterproofing: variety of materials and features of choice Consumption of polymer waterproofing
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, objects engineering infrastructure and public 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 as an additional means that increases the reliability of other methods of ensuring concrete waterproofing. Various brands and polyurethane-based compositions 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, due to the chemical resistance, durability and elasticity of the film that is formed during application protective compounds on the grounds.
- Elasticity allows you to partially compensate for the deformation of the base, so the polymer film of 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 surface treatment complex shape. 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. Employees of the technical support department provide free consultations on the selection of polymer waterproofing for floors, walls, foundations, technical tanks and other tasks. Advice 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 bitumen materials were used to protect against moisture. 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 is best done using polymer cement mixtures, and bitumen-polymer mastics are also suitable for concrete. Unlike roll coatings, the water-repellent layer obtained with these materials is inseparable from the surface.
- Resistance to any weather factors (temperature changes, ultraviolet radiation, precipitation), water pressure, exposure to aggressive chemical substances. 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. Composition, viscosity almost equal 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. The material is applied in a 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 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 the necessary properties: plasticity, fluidity, frost resistance, the 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 is ready for application; two-component compounds are 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, it is necessary to take into account the properties of the surface being processed, 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 famous brands, which have long proven themselves on the 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 based on a polymer is applied in a thin layer, so a smaller amount of 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 unevenness, protrusions, concrete sagging, smooth out sharp corners;
- if necessary, level the surface 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 polymer waterproofing, weak areas of the surface are reinforced. 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.
All structural elements houses or apartments require reliable protection from high humidity. Why is waterproofing needed?
In a room located above a damp basement, moisture destroys the concrete of the floors. IN wooden covering High humidity causes mold to grow and rotting begins. IN multi-storey buildings on middle floors, when moisture penetrates through cracks at the joints of the floor, carpet, laminate, parquet, bamboo lose their original appearance, 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 you avoid such problems in your home, increase the safety of its operation, and improve comfortable living conditions.
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 laid using a gasoline or gas burner; when heated, it releases bad smell, 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, self-adhesive film made of polyvinyl chloride, polyethylene, and polypropylene is used. Usually pvc film used to create a dry or cement-concrete screed for a 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 replaces rolled materials because, unlike them, it does not have an unpleasant odor and does not form seams that could cause water leaks.
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 used to create floor 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 - at the junction of the floor and the walls 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 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 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, or 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 includes laying roll and sheet moisture resistant materials layers onto 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.
- Gluing using special adhesives and mastics. 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
A simple, environmentally friendly method using various dry cement-based mixtures with the inclusion of binding mineral and 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.
Used as a filler perlite sand, ash, mineral wool, bentonite. 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 the individual characteristics of the room’s operation - humidity, the presence of a “warm floor” heating system, the presence of a toilet, a 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 or rolled material - a geomembrane - are also used.
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.

Polymer waterproofing
Polymer waterproofing
IN Lately Waterproofing materials have become extremely widespread different types. Quite common polymer insulation, presented on the market with almost the largest number of brands and materials.
The use of polymer is one of the most promising ways to develop construction, since polymer materials provide increased resistance of structures and buildings to aggressive forces. environment, as well as restoration of the lost life of the structure.
Today, the most widely used effective waterproofing materials for protection against moisture are: bitumen-polymer, acrylic and polyurethane.
Polymer waterproofing used for all types of structures. Its most effective use is for waterproofing industrial reinforced concrete and sanitary structures, various treatment facilities household, industrial and sewage wastewater, as well as containers for storing harmful liquids and complete chemical protection concrete. In the vast majority of cases, it is used in the form of mastics for coating the external parts of structures and structures.
Polymer compositions are intended mainly for waterproofing various dry surfaces, but there are compositions with special surfactant additives that significantly increase the adhesion of materials to a damp base. They are designed for waterproofing wet concrete surfaces. Most often, polymer compositions are prepared directly on the job site, for which a polymer cocktail of resin, plasticizer and hardener is mixed. Depending on the composition and purpose of the material, the viability period of the prepared solution ranges from several minutes to several hours.
Bitumen-polymer compositions are high-quality materials based on bitumen diluted with polymers and rubbers. These additives have improved the water resistance, durability and deformability of bitumen mastics, and they also regulate the operational and technological properties of bitumen. polymer compositions. Bitumen-polymer compositions are the development of bitumen waterproofing technology, inexpensive, but not very durable. Thanks to the addition of new types of materials, it was possible to obtain relatively inexpensive, but already durable and high-quality waterproofing.
In general, polymer waterproofing is confidently gaining popularity among domestic consumers. The main advantage of materials in this group is their relatively low cost with fairly high quality insulating layer.
Waterproofing wet areas – important factor healthy and comfortable microclimate throughout the living space. This is a barrier to the penetration of moisture from bathtubs, showers and toilets - the most damp rooms in any apartment. Until recently, the most popular and frequently used were waterproofing materials based on organic components - bitumen and bitumen-polymer mastics. However, modern polymer waterproofing is a much more “advanced” and high-tech material.
What should high-quality waterproofing be like, what criteria should it meet? Its main task is to prevent the penetration of moisture from one room to another. Moisture entering the thickness of the walls destroys brickwork And plaster layer, forms pockets of fungus and mold under wallpaper and putty, spoils appearance repairs and the mood of the owners. Therefore, everyone must fight it available methods, but it’s better to use materials specifically designed for this purpose.
Based on the method of application, waterproofing materials have always been divided into roll and coating materials. The first ones are more difficult to install, and the result was not always reliable - this is already “yesterday”. Materials that are applied to the surface with a brush or roller are much more convenient and reliable. These include polymer-cement waterproofing.
This group of materials is produced on the basis of inorganic substances and has a number of advantages over traditional ones bitumen mastics.
The materials are produced by many manufacturers who patent their developments and technologies, but in general, cement-polymer waterproofing materials include the same components: Portland cement, fine sand, elasticizing polymer substances. One-component and two-component mixtures are available for sale. The former contain dispersion polymers in the form of powders (DPP), the latter contain aqueous polyacrylic dispersions as an elasticizer.
Ease of application is one of the advantages of polymer-cement waterproofing
Advantages of polymer-cement waterproofing materials
- Waterproofing compounds consist entirely of substances that are safe for health, so they can be used indoors for human habitation.
- Waterproofing based on inorganic materials has a significantly longer service life compared to bitumen. These materials have excellent adhesion to all materials used in construction - concrete, brick, wood, metal.
- Ease of application - cement-polymer waterproofing is applied to surfaces using conventional paint brush. This allows you to efficiently coat the slightest irregularities, since it is clearly visible where the composition was applied unevenly and there are “bald spots” in the layer of material. Repairing the coating is also very simple.
- The waterproofing layer completely blocks the path of water, while allowing water vapor to pass through - the wall “breathes”. This property prevents the formation of air bubbles under the membrane. Main feature This material can be applied even to a damp wall; moreover, it is recommended to moisten the surfaces before starting work.
- The resulting layer has high plasticity and resistance to deformation, which eliminates its damage in the event of small cracks forming on the base.
The advantage of polymer-cement compositions is the possibility of application to wet surfaces
Step-by-step guide to moisture-proofing a bathroom with polymer-cement compounds
Using this type of material, you can get excellent results. To do this, you must carefully follow the manufacturer's recommendations for application. cement-polymer waterproofing. In general, they are approximately the same, the differences can only be in the numbers - drying time of the layer, thickness, and in the method of preparing the material for work. Before starting work, it is necessary to mark those “wet” areas that will be subject to increased exposure to moisture - walls around the bathtub, washbasin, etc. Be sure to apply the coating to the lower part of all walls (25-30 cm) and the entire floor area.
“Wet” areas of the bathroom require particularly careful treatment.
- Preparation of the base (walls, floor) must be carried out with the utmost care. It is necessary to remove all debris and dirt, dried splashes mortars. Irregularities are filled with plaster.
- Typically, the manufacturer indicates the need to wet surfaces before applying the composition. If there is such a remark, it is necessary to moisten the base using a regular spray bottle.
- Preparation of the material: mixing all components of the polymer-cement composition in the sequence specified by the manufacturer. The mixture should become homogeneous.
- The composition is applied to all marked surfaces using a hard brush in an even layer. Carefully ensure that there are no “mispaintings”. At the junction of walls and floors, as well as water pipes, sewer pipes or risers, it is necessary to lay a layer construction mesh from polypropylene, geotextile, etc. material. It is embedded in a layer of waterproofing material and lubricated well.
- The first layer is dried for the time specified in the manufacturer's instructions. It is better not to artificially reduce this period by drying with heat guns or construction hair dryers.
- Before applying the second layer of material, the surface is slightly wetted again (if recommended by the manufacturer). The second waterproofing layer is applied.
- The surface is dried according to the recommendations of the material supplier, after which it is ready for applying decorative finishing.
The joints between the walls and floor of the bathroom must be taped with waterproofing tape.
Features of polymer coating waterproofing
This group of materials also belongs to modern one-component coating compositions for “cutting off” moisture. They contain acrylic, epoxy or polyurethane resins, which give them very high ductility. Superficial active substances increase the adhesive properties of polymer compositions for waterproofing work. The resulting layer has high vapor permeability, it is very elastic, but durable, similar to rubber. This material is applied with a brush or roller, and the surface is pre-moistened.
Although polymer waterproofing for the bathroom is not subject to the aggressive influence of chemicals, it is nevertheless very resistant to such influences, so it is most often used for work on outdoors– for waterproofing swimming pools, sewerage and treatment facilities, etc. Materials intended for indoor use can be made in a wide range color scheme, under the influence of ultraviolet radiation on the street they fade very quickly.
Indoors you can use polymer waterproofing of any color
General recommendations for the use of polymer waterproofing compounds
- When applying any materials, be it wallpaper, paint or waterproofing compounds, preparation of the base is very important. Mark areas on the walls that will be exposed to increased moisture. The lower part of the walls and the entire floor must also be waterproofed.
- The walls and floor must be well dusted, cleared of any build-up of mortar or plaster, and large potholes must be leveled. All debris is carefully removed. The surface must be dry.
- Concrete, metal surfaces primed with special primers recommended by the manufacturer.
- The first layer of the composition is applied at temperatures above 0 ° C, exact time hardening is indicated on the packaging by the manufacturer; this is necessary for polymerization of the applied composition. In places where the floor and walls meet, as well as the outlets of risers and pipes, it is advisable to lay a layer of geotextile or polypropylene construction mesh. The material is well coated and embedded in the waterproofing layer.
- After the first layer has hardened, the second one is applied. To make it more convenient to control the uniformity of application of the second layer, it is better to make it contrasting color. In places where the bottom layer is visible, after the second layer has hardened, you need to apply the mastic again.
- After the second layer has hardened, the surfaces are ready for decorative finishing.
Polymer waterproofing in the bathroom
In general, the process of applying modern waterproofing compounds is quite simple. However, as in any work, there are a number of subtleties that are familiar only to specialists. To keep your bathroom sparkling clean and the walls of neighboring rooms dry, invite professionals and let everyone do their job!
