What is cement waterproofing, main types: coating, polymer, methods of application. Modern polymer waterproofing - a reliable barrier to moisture in the bathroom Polymer waterproofing

Cement waterproofing provides protection of various structures from moisture. Materials of this group are used frequently due to many advantages. With proper mixing of the components, high reliability is ensured, and the service life of the coating is increased. There are different types of cement-based mixtures. When choosing, their composition and properties are taken into account.

Peculiarities

Waterproofing mixtures are used to protect various surfaces from water: floors, walls and ceilings, seams, etc. Cement-based materials have become widespread. This is due to the reasonable price, relatively simple application.

Despite the fact that the cement absorbs some moisture, mixtures containing such a component provide high protection against water. At the same time, there are no contradictions in properties, since special additives are used in the manufacture of cement-based waterproofing, which greatly improve the characteristics of the material.

For waterproofing surfaces, compositions containing tension cement are used. It is distinguished by increased strength, resistance to cracking. Compared to other brands, this cement absorbs moisture minimally. The use of hydrophobic additives, plasticizers helps to increase resistance to water, enhance reliability by increasing the plasticity of the mixture.

Waterproofing is applied in a layer of significant thickness, due to which the treated structure is better protected. The principle of application is similar to the method of use plaster mixtures. Thanks to the waterproofing layer, condensation does not form, which gradually destroys the structure and cladding. As a result, the protected surfaces retain their attractiveness longer and also serve for a long time.

Advantages and disadvantages

Positive traits:

a wide range of applications: foundation protection, fencing of single-storey and multi-storey buildings, waterproofing of pools and reservoirs in contact with water, preparation for lining bathrooms, balconies, application to structures that are exposed to a significant load of water under pressure, when premises are flooded;
high degree of protection against moisture, cement-based waterproofing can be used in any conditions, even in the most difficult ones;
simple principle of application;
the possibility of applying to a moistened surface, which is due to the presence of cement in the composition, the adhesion of which only increases if the humidity of the protected surface is first increased;
ensuring protection against corrosion;
no chemical reaction upon contact with aggressive media;
impact resistance low temperatures;
vapor permeability;
no harmful ingredients.

There are few disadvantages of such mixtures. They note the possibility of applying only to structures that have already gained strength. In addition, cement-based waterproofing materials provide a high degree of protection, provided that several layers of material are applied to the structure to be protected.

Varieties in composition

When choosing, take into account the type of components, the structure of the mixture. The material is selected taking into account the intended purpose of the protected structure, operating conditions. Waterproofing must correspond to the temperature regime at which it will be applied and serve in the future. Violation of this condition will lead to the gradual destruction of the protective layer.

Cement-sand waterproofing

The composition is produced in the form of a dry mixture. This is the simplest type of waterproofing in terms of properties, which is due to the use of cement as the main component. The mixture is quite hard, during the drying process, the protective coating should be moistened frequently - up to 3 times a day for 2 weeks.

For application, it is recommended to use the method of spraying the composition using special equipment. The main purpose of the cement-sand mixture is to protect the monolithic foundation of objects. If you plan to apply waterproofing with your own hands, special additives must be introduced to increase the density of the composition. Without them, the service life of the waterproofing will be reduced, and the coating will not perform its functions.

The mixture is applied successively several times. When the work is completed, it is recommended to protect the structure to be protected from possible damage during the drying time.

However, the surface of the waterproofing layer can still be deformed. In this case, moisture evaporates unevenly, which leads to a change in volume with different intensity.

With added latex

Due to this composition, the plasticity of the material is ensured. Latex increases the resistance of waterproofing to cracking. The material tolerates the effects of temperature extremes and low values of this parameter much better. As a result, the cement mixture resembles liquid rubber in appearance and properties. After applying the material, an impermeable coating is obtained, which reliably protects the structure to be protected from moisture.

You can add latex to the cement mixture yourself, observing the proportions. However, it is much easier to use a ready-made mixture.

Mandatory conditions when working with such material:

application of the method of shotcrete or spraying on a surface that has previously been carefully prepared;
the mixture should be hot.

The result is a seamless coating that does not let moisture through, does not crack, is resistant to mechanical stress and lasts a long time, and also withstands high temperatures.

With liquid glass

Such a component is added to the cement mixture, which improves the properties of the hard cement-sand mortar. Most often, the material is used to protect the foundation, ground floors, for the formation of refractory coatings.

Advantages of compositions based on liquid glass:

protection against high temperatures;
high adhesion;
manifestation of antiseptic properties;
the absence of toxic components in the composition.

Various uses:

liquid glass is applied to seams, joints, cracks, this option is used as an auxiliary measure, after applying this type of waterproofing, roll material is also used;
liquid glass is used as the main component of the cement mixture intended for pouring the foundation.

Cement-polymer

The composition includes Portland cement, sand, plasticizers. Cement-polymer waterproofing has improved properties. The main advantage of this material is considered to be high resistance to tensile and tear loads. This is due to the formation of molecular bonds in the combination of polymer components and cement. As a result, the protected structure tolerates dynamic loads well and is resistant to cracking.

There are different types of polymer cement mixtures:

waterproofing adhesive;
waterproofing.

There are one- and two-component formulations. Moreover, the second of the options is more common. It consists of acrylic emulsion, microfiber. Such material is used when there is a high risk of exposure to deformation loads (cracks of more than 1 mm are formed). In other cases, dry one-component mixtures can be used.

Types of compositions according to the method of application

Materials differ in structure and method of application. The choice is made taking into account the state of the protected structure. Penetrating compounds are preferred for use on surfaces that are porous. Coating-type cement waterproofing, plaster and elastic coating mixture are applied to the surface. Certain types of materials are intended only for the repair of objects.

Coating

This is the most common mixture, it is used to protect various surfaces during construction and at the stage of repair: floors, walls, ceilings, balconies, bathrooms, foundations, water tanks. Coating waterproofing allows you to create an impermeable layer on the protected surface, which carefully protects against water.

It is operated for a long period, fills the smallest cracks. Such a composition can be applied to surfaces made of different materials: drywall, metal, brick, wood, concrete, etc.

Elastic coating

This group includes materials containing plasticizers. These are auxiliary components that are used to increase the elasticity of the cement composition. This type of mixture is recommended to be used to protect surfaces of complex configuration, prone to the formation of small cobweb cracks up to 0.5 mm wide.

The advantages of elastic waterproofing include increased strength. It is permissible to apply it on surfaces: pools, terraces, balconies, water tanks. It differs from the classical waterproofing of the coating type by a high price.

Plaster

This version of the material is prone to cracking, so it is not recommended to use it under increased dynamic loads. The surface of the protected structure should not be deformed, then a significant duration of the waterproofing service is provided. To improve the properties, it is allowed to add auxiliary components, for example, liquid glass. This type of material has the advantage of being able to level curved surfaces and at the same time provide moisture protection.

Penetrating

Waterproofing of this type can only be used to protect structures made of concrete and reinforced concrete. This is due to the fact that the composition provides efficiency, provided that the protected surface is porous. Waterproofing penetrates into the structure of concrete, upon contact with the moisture contained in such material, it crystallizes, clogging the pores.

This prevents the risk of moisture penetration. Such a composition is used when it is not possible to protect the outer surfaces of the structure with the help of external waterproofing.

Repair compounds

Differ in high speed of drying. This type of material is recommended for filling joints, cracks. It can be used on different surfaces, including when restoring the foundation. The advantages of this mixture include the absence of shrinkage upon drying.

water stopper

The material is used when it is necessary to quickly restore the integrity of concrete pressure structures. It is used to repair objects made of stone, concrete, reinforced concrete. Produced in dry form. Upon contact with water, when a blockage occurs with a mixture of a deformed area in the thickness of a concrete or stone structure, the cement composition instantly hardens, forming an impenetrable barrier to water. The advantage of a water stopper is its high adhesion to the protected surface. It is used even in the presence of a leak.

Application technology

Instruction:

If the base is old, it is repaired: the top layer is removed, cleaned, leveled with special mixtures.
Before applying cement compositions, the surface is moistened.
When the excess moisture evaporates, and the protected structure is slightly moistened, waterproofing is applied.
In the work, a spatula or special equipment is used to spray the mixture.
The material is applied several times. After the formation of the first layer, you need to wait 2-3 days, during this period the surface is moistened.
For 3 days, until the first layer is dry, apply the next, and then another. Cement-based waterproofing must not be allowed to cover a dry surface.

Manufacturers

To purchase high-quality certified material, they consider products of common brands. It should be borne in mind that prices vary in Moscow and regions.

Ceresit CR 65

This is cement hard waterproofing. Application area:

internal and external surfaces;
structures buried in the soil;
pool bath and other reservoirs;
protection of walls, floors and ceilings in rooms with high humidity;
waterproofing of hydrotechnical and treatment facilities;
protection of various objects from destruction and exposure to low temperatures.

On deformable objects, an elasticizer is added before applying the mixture.

Bergauf Hydrostop

Waterproofing belongs to the group of materials of coating type. This is a one-component mixture, applied with a thickness of 1-5 mm. It gains strength after 28 days, it is resistant to bending and compression loads. The composition can be used at high and low temperatures: -50…+70°C.

Cement NTs

Stressing cement belongs to a separate group of materials, since it has a high linear expansion rate, does not shrink, does not deform. This is the most durable substance, and also wins in comparison with Portland cement in terms of moisture resistance. The material contains almost no pores, therefore it protects well from moisture.

All structural elements of a house or apartment require reliable protection against high humidity. What is waterproofing for?

In a room located above a damp basement, moisture destroys the concrete floors. IN wood flooring from high humidity, mold starts, rotting begins. IN high-rise buildings on the middle floors, when moisture penetrates through the 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 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 -. The floor waterproofing device will help not to face similar problems in the home, increase the safety of its operation, increase comfortable conditions residence.

materials

Depending on the purpose, conditions of use of the premises, the condition of the subfloor, financial costs, various materials are used for waterproofing, which protect it from destruction. All types of waterproofing make up two main groups - for outdoor and indoor use.

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

bituminous - based on mineral components;
polymeric;
bitumen-polymer.

According to the method of application on the surface, the main types are distinguished:

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

Roll and self-adhesive waterproofing

They are widely used for floor waterproofing in apartments and private houses. Roofing material for waterproofing has been used to date, along with roofing felt and glass roofing material. Cardboard or fiberglass impregnated with a mixture of bitumen, basalt chips. They can be laid to protect foundations, roofs, floors from moisture. Modern waterproofing materials have additional thermal insulation properties.

Roll waterproofing - membrane (geomembrane). It has a lock at the junction. Additionally, bonding is carried out.

Rolled waterproofing materials are of two types: floating and self-adhesive. Surfacing materials are durable, inexpensive in price. Their disadvantage: it is necessary to lay the waterproofing using a gasoline or gas burner, when heated, they emit bad smell, harmful smoke. The method is quite suitable for use in the country with your own hands when waterproofing the underground. Laying roofing material during waterproofing requires the installation of an additional screed.

Self-adhesive waterproofing is quickly installed, 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, polypropylene is used. Typically, PVC film is used to create a dry or cement-concrete screed on a concrete floor. Working with self-adhesive film does not take much time.

penetrating waterproofing

applied as the main or additional measure of protection of a concrete floor. Includes subgroups:

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

Ceramic tiles are easily laid on the penetrating waterproofing layer.

Mastics

plastic adhesive solutions based on bitumen, liquid rubber, polymers, resins, plasticizers, and other additives. Mastic solutions are either hot or cold. Mastic for waterproofing the floor is used to create a waterproof layer, processing joints in the bathroom, toilet, kitchen, bath, swimming pool. Mastic displaces rolled materials, since, unlike them, it does not have an unpleasant odor, does not form seams that can 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

to protect against moisture, they are represented by a variety of dry mixtures based on cement, glue, binders, plasticizers.

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

Execution Technologies

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

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

Polymers and bituminous compounds

Cast - the application of polymer or bituminous solutions, which, when solidified, 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 process fused bases before pouring the screed. It is possible to lay waterproofing in several layers, between which a metal reinforcing mesh or reinforced fiberglass is laid; the thickness of the waterproof film can be 5 - 15 cm. The base of the floor is impregnated with a waterproofing material.

Coating the surface 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.

Rubber crumb, plasticizer, latex are used as additives, 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 between the waterproofing layer and concrete base. Mastic can be sold complete with a primer, they have a common main component. The main advantages of coating materials are economy, ease of application.

Coloring

How to make floor waterproofing by painting? Staining is used for the floor along the logs, for wooden or concrete pavement. A polymer or bituminous varnish is used. Depending on the consistency of the composition, it is applied to the surface with a spatula, roller, paint brush. The layer during 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 the floor with gluing materials? This method includes laying rolled and sheet moisture-resistant materials in layers on a pre-cleaned and primed floor base.

Types of adhesive waterproofing:

Conventional flooring on the surface under a cement or dry screed, under a wooden rough covering with a joint or independent fastening method.
Fusing rolled material on the floor with a gas burner. The method is flammable, requiring skills and strict adherence to fire safety rules.
Bonding with special adhesives and mastics. Many types of modern film waterproofing have an adhesive layer, which greatly simplifies their installation. The melting point of the mastic on a bitumen-polymer basis is selected 20 - 25 ° above the highest air temperature of a given room.

All types of pasting materials react to shear, and therefore they are used to protect rigid structures made of brick, concrete, reinforced concrete from high humidity. Such laying of waterproofing is also used for a wooden rough coating.

Plaster

Easy to perform, environmentally friendly safe way with the use of various dry mixes based on cement with the inclusion of astringent mineral and polymer additives. The solution well fills any irregularities, cracks, cracks in the treated surface. The mixture is applied with a spatula or brush.

Mastic and plaster

Mastic for floor waterproofing. Features of work with mastic and plaster.

After applying the self-levelling material, the floor must be in a calm state for the curing of the composition. The mastic is applied in several layers - at the same time, each subsequent layer is applied perpendicular to the previous one after it has completely dried.

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

Backfill materials

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

As a filler, perlite sand, ash, mineral wool, betonite are used. Backfill hydroprotection has a long service life, but its installation is a laborious and expensive process.

Choice for a room

When choosing a material and method for floor waterproofing, it is necessary to take into account the individual characteristics of the operation of the premises - humidity, the presence of a "warm floor" heating system, the presence of a toilet, a swimming pool.

Especially carefully it is necessary to carry out work in the country in the garage - a constant excess of moisture will lead to rotting of vehicles. What waterproofing to choose to protect the floor in the garage?

The best solution is concrete. Waterproofing under the concrete floor - penetrating, impregnating, additives in concrete when preparing the mortar. Immediately before pouring concrete, the soil is poured with bitumen, building clay is also used, or rolled material - a geomembrane.

It is possible to use a combined method of waterproofing - the first layer is laid with a roll coating, then all the joints that have appeared are sealed and a layer of mastic is applied on top.

Preparation for work

Before starting work on hydraulic protection, preliminary measures are taken with the subfloor:

removal of the old coating;
thorough cleaning, 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 the right choice of material, adherence to the laying technology.

The use of high-quality waterproofing materials, selected in accordance with the operating conditions, improves reliability and reduces the cost of maintenance and repair of buildings, roads, 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.

Elastic polymer waterproofing, depending on the range of tasks to be solved, can be used as an independent waterproofing material or an additional tool that increases the reliability of other methods for ensuring concrete waterproofing. Various brands and compositions based on polyurethane 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, which is formed when protective compounds are applied to the bases.

Elasticity allows you to partially compensate for the deformation of the base, so the waterproofing polymer film always remains intact and tight.
Polymer-based materials have good adhesion to concrete, brick, cement plaster, tiles, metal and other materials. They can be applied on absorbent and non-absorbent substrates. The waterproofing layer can serve as a base for sprayed concrete or finishing materials.
Polymer waterproofing of concrete allows processing surfaces of complex shape. The coatings exactly follow the contours of the base and do not have seams that reduce the effectiveness of protection.

Materials based on polyurethanes are very technologically advanced. They are quickly applied to pre-prepared substrates: liquid polymer waterproofing using spray guns or special equipment for spraying two-component formulations, and pasty mixtures with conventional brushes, brushes and rollers.

Supplies of polymeric waterproofing materials

In the online store "MPKM" wholesale prices for building chemicals, Sika, and other manufacturers with fast delivery of 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. The advice of an experienced specialist will help you buy waterproofing materials that are best suited for certain operating conditions and correspond to the characteristics of a particular object.

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

Peculiarities

Polymer waterproofing mostly consists of a bituminous emulsion, which includes latex particles. The choice of this waterproofing solution on the shelves of hardware stores is huge. The composition may vary. The content of the composition is directly affected by the manufacturer and the purpose of the solution.

Do not forget that a certain air temperature can affect the insulating compositions. This induces polymerization. As a result, a strong and viscous membrane is formed. Its characteristics meet all requirements in the process construction works.

Advantages and disadvantages

The use of a polymer base as insulation has many advantages. By choosing the right waterproofing composition and the specifics of its application, you will get a surface that has a water-repellent property.

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

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

High wear resistance 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.
Economic consumption of the material is achieved by a slight thickness of the coating of the polymer composition. This is quite enough to create a solid waterproofing.
Creation of adhesion with different materials, such as concrete, metal or wood, as well as many different types of finish coating.
This waterproofing composition is easy to apply. 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 favorably affects the overall progress of construction work.
The absence of toxic evaporation 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 an existing one around the entire perimeter or in the required area.
The polymer composition has a vapor barrier, 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, the polymer waterproofing composition has disadvantages, of which its high cost can be highlighted. The composition is much more expensive than its counterparts, such as roofing material and bitumen. But it is worth noting that the quality of the resulting coating will fully justify the high cost.

Recognizing the merits and benefits of this option will allow reducing the financial costs of additional repairs and replacing a 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 with the variety of insulating compositions offered by manufacturers in advance.

There are several criteria that will help you choose the right material that meets 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 format of a rolled membrane, which is not inferior to liquid bases, but it is in little demand among consumers.
Function. To date, the manufacturer is developing a huge range of models for its proprietary 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).
Included components. The elements used and their combination divide the polymeric waterproofing composition into several types. The most popular today are cement-polymer and bitumen-polymer composition.

Application technology. The application technology is influenced by several aspects, including experience with waterproofing work, available deadlines for 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 of composition: coated polymer waterproofing, liquid, home-made solution (which is based on epoxy resin). Waterproofing polymer compositions produced for self-preparation 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 cooking container. Such quick-hardening compositions will cost you less if a person with special skills and owning the necessary equipment will work. For independent 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 direct purpose. For example, it is often used for surface and underground structures, hydraulic installations, as well as wet rooms. Elastic polymer cement two-component waterproofing is most often performed in mixtures. Also, sprayed waterproofing has good reviews.

Application specifics

As 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 that you have purchased the required amount of the mixture;
prepare the surface for further finishing work;
process all the necessary structural elements with a polymer composition, following the recommendations from the manufacturer;
wait until the surface is completely hardened.

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

So, there are two ways to apply polymer waterproofing:

coloring- for the implementation of this procedure, it is recommended to purchase a paint brush and roller in advance;
spraying– This technology will require an airless pumping unit.

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

When deciding to carry out the waterproofing process as soon as possible, spraying technology will suit you. For the correct execution of the process, you must adhere to a simple algorithm:

Carry out the preparation of the pumping airless installation. Make sure the equipment is complete.
Prepare unconcentrated calcium chloride. If you purchased a ready-made solution, fill the container with it.
Connect the container to the airless pumping unit.
Also connect a container with a polymer composition for waterproofing.
Next, spray the composition on necessary elements structure or surface.
Make sure that two containers work at the same time when spraying, as the compositions must be mixed.
The final result should be an even layer that will be between 2 and 4 millimeters thick (depending on the design configuration), so try to direct the jet in such a way as to achieve this result.

Coating application technology will become a budget option for waterproofing. Using a similar method, you have the opportunity to perform high-quality waterproofing of a small space or individual structural elements, while the consumption of the polymer composition will be minimal.

Let us consider in more detail the stages of waterproofing work:

Acquire and prepare the necessary tools. Depending on what type of construction you are processing, the choice in favor of a fine-haired paint roller or wide brushes will depend.
Blot the bristles of a roller or brush into a waterproofing polymer compound.
Paint all necessary areas, trying to cover the surface in such a way that the coating is two to four millimeters thick.
Wait until the surface is completely dry.
Repeat the procedure with another layer.

If it is important for you to obtain a uniform and smooth surface, the construction level will help to check the quality of the work done. Thanks to him, 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 in advance - the surface. To do this, you will need to mark areas that are more susceptible to moisture. It should be noted 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 out before applying the polymer base.
