Do-it-yourself self-leveling polymer floor. Creating polymer floors with your own hands. Video - Pouring polymer floors

Construction is an important industry today. National economy. Special place in this section have work on the manufacture of the floor in a particular room. Today, for the construction of the floor, you can use a wide variety of materials: wooden boards, plywood, linoleum, concrete pavement. AT last years the so-called liquid polymer floor is gaining more and more popularity. It is also called bulk. Unlike conventional materials, it has a number of advantages.

Polymer floors are divided into such types as: epoxy, polyurethane, methyl ethacrylate.

Polymer self-leveling floors are a synthetic coating. Most often it is used in large retail premises, garages, exhibition halls, etc. Very often, polymer self-leveling floors are used in production due to their strength and durability. It is easy to make such floors with your own hands. In addition, there are 3D floors. They differ from the previous coating in the presence of complex drawings, which not everyone can do with their own hands. Let us consider in more detail how to pour polymer floors, the main stages of work, positive and negative sides this coverage.

Advantages and disadvantages of self-leveling floor

Polymer self-leveling floors have a number of positive qualities which is why they are in high demand.
First, polymer floors are different types(epoxy, polyurethane, methyl ethacrylate), depending on this, they can withstand high temperatures, do not let water through.

Second, despite the use polymer base, they are hygienic, easy to process and wash. Thirdly, this coating is resistant to various chemical agents.
Fourthly, polymer floors can be glossy or matte, so you can choose the desired design in accordance with the interior of the room. Fifthly, polymer floors contain a liquid component that quickly hardens. This contributes to better adhesion of the liquid to any surface, be it wood or concrete. Unlike a wooden and concrete base, this coating is done quickly and without much effort.

Preparatory work

The complexity of the construction of self-leveling floors is that they require a perfectly flat surface. In the event that the base is represented by tiles or tiles, you will have to create some roughness. This can be done with sandpaper or sandpaper. Often there are problems when leveling the base if it is made of wooden planks. To do this, first close up all the bumps. The unevenness of the base of the floor can be well manifested when disassembling the log and removing the old coating.

The permissible difference in the height of the self-leveling floor surface is 4 mm. If possible, then you can make a screed of concrete. If it is not done, then irregularities and defects are removed with a grinder or grindstone. To determine the evenness of the coating, it is recommended to use a water or building level. It is also advisable to carry out surface priming. The primer prevents the penetration of moisture and increases the adhesion of the self-leveling floor to the base. After the base is made, along the perimeter of the room it is necessary to nail the slats like a plinth. This is necessary so that the liquid polymer mixture does not spread into the voids between the floor and the wall. The slats are fixed with self-tapping screws, nails (if the wall is wooden) or dowels (if the wall is concrete).

Preparation of the mixture and pouring technology

In order to make polymer floors with your own hands, you will need to prepare a working solution. You can buy a polymer mixture in any hardware store. After that, it must be diluted in water. This is one of the most important stages of the whole work, since the result of pouring largely depends on the quality of the solution. It is necessary to prepare the mixture only according to the instructions attached to the product. Great importance has a mixing process. This should be done slowly so that not a single lump remains. In addition, there should be no air bubbles in the solution.

Mixing can be done using a special mixer or improvised means. The next stage of the repair is pouring the solution. Liquid polymer must be applied to the surface from the most distant part of the room from the doors and gradually move towards the exit. The optimal floor layer should be about 4 mm. If you make it thinner, then it will not have high strength and reliability. This option is suitable as an addition to the main coating. It is best to fill the mixture with two people with an assistant. One person holds a container with a polymer liquid and gradually applies it to the floor, while the second person levels the surface. For alignment, you can use a wooden lath.

After the polymer self-leveling floor dries, you can start applying varnish. Varnish is needed to give the coating a certain sheen. In addition, the varnish increases the wear resistance of the material and makes it smoother. The drying time of the polymer mixture is on average about half an hour. But it is best to read the instructions on the package. The varnish is applied only on a hard surface. It is recommended to paint the floor in two or even three layers. Walk in a new way self-leveling floor you can not immediately, otherwise traces may remain on it.

Most homeowners planning to renovate or refurbish floor covering, tries to focus on modern technologies and the most popular design solutions. Often, in the process of choosing a floor covering, one has to face a number of difficulties, since modern material for finishing the floor must meet many characteristics and be appropriate even in rooms where the flooring will be subjected to a whole "set" harmful effects- from chemical to abrasive, without losing its decorative and hygienic characteristics. All these requirements are met polymer coating for the floor, which is very popular in modern construction sites and featuring high performance. Polymer floors, also called liquid linoleum, are a seamless finishing polymer floor coating applied to concrete base, cement-sand screed, ceramic tiles or wooden floor. Polymer floors, being a high-tech modern floor covering, have all the characteristics that are not characteristic of either concrete, or linoleum, or ceramic tiles and relevant to present stage design development. Despite the fact that previously polymer floors were considered only in the context of premises industrial use, then today, thanks to the use in the process of their production modern technologies, they have become relevant in residential areas. In connection with the relevance of polymer flooring, this article will consider its main varieties, their a brief description of, as well as advantages and disadvantages.

Varieties of self-leveling floors: a brief description

Mineral poured coatings

The demand for self-leveling floor is partly due to wide choice its varieties presented on the construction market. Modern manufacturers offer two main types of bulk coating: mineral and polymer. The mineral coating is cement mixture, supplemented by a number of fillers that largely determine its performance characteristics. Mineral self-leveling floor is a leveling composition that is used to prepare the surface immediately before laying ceramic tiles, linoleum, laminate and other floor coverings.

There are three types of mineral mixtures:

Base mix designed for the initial leveling of concrete and cement surfaces with slopes up to 80 mm. Leveling the surface with the base mixture is not final, since it is necessary to make additional adjustments with the help of mixtures for the middle layer;
The average mixture is used as the main composition for leveling surfaces characterized by slopes of not more than 30 mm;
The finishing mixture is intended for the final leveling of the bases on which the flooring is laid.

Polymeric coatings

No less popular is another type of self-leveling floors - polymer coatings. They are characterized by predominant use in rooms where increased requirements are placed on the floor covering, such as resistance to mechanical and chemical influences, lack of tendency to abrasion and environmental Safety. There are several actual classifications of polymer coatings that group the types of polymer coatings in accordance with a certain feature. Most often, polymer coatings are classified taking into account:

The binder component used in the composition of the mixture;
Degrees of filling and material thickness.

Consider the main types of polymer coatings for concrete floors.

In accordance with the binder used, they are isolated the following types polymer coating:

Epoxy resin coating for the floor is characterized by moisture resistance, high strength and resistance to mechanical and chemical effects of acids, alkalis and oils, which not every floor covering can boast of. The use of epoxy coating is relevant only in enclosed spaces in which certain sanitary and hygienic requirements are established. It is in them that conditions are created for the intensive impact of mechanical loads and aggressive liquids;
Epoxy urethane blends, the use of which is justified only in areas characterized by heavy traffic, such as platforms and parking lots. Being high-strength compounds resistant to abrasion, they retain their elasticity throughout the entire period of operation;
Polyurethane poured coating characterized by high wear resistance, impact resistance high temperatures and chemical substances, which leads to a long period of coverage, reaching 20 years. Distinctive feature polyurethane floors - smoothness and lack of seams, thanks to which they will never turn into a dust collector. This is the main principle of their high aesthetics. Taking into account these features, it should be noted that the polyurethane self-leveling floor is perfect choice for rooms characterized by constant vibration load and mobility of the floor, as well as frequent abrasive effects on the floor covering;
Methyl methacrylate coating characterized by the least popularity, due to the difficulties that arise in the process of its installation. Despite the fact that the methyl methacrylate coating is characterized by minimal resistance to mechanical stress, it still remains unrivaled for unheated premises.

Considering the above, it can be concluded that great variety polymer materials for flooring. Despite the fact that the binder component of the polymer composition largely determines its performance, it is not the only factor that is guided by when choosing a self-leveling coating.

Important! Another important parameter characterizing the bulk coating is the thickness. During operation, a polymer layer of a certain thickness is erased annually from the surface of the polymer coating, which is determined by the composition of the polymer, as well as the intensity of the load and varies within 10-30 microns.

In accordance with the thickness and degree of filling of the coating, the following categories of polymer coatings are distinguished:

Thin-layer polymer coatings(thickness usually does not exceed 0.5 mm), also called painting by the method of application, are characterized by a minimum operational period and predominant use in rooms with minimal traffic, and, consequently, mechanical stress;
Bulk, also called self-levelling, being the most popular type flooring, characterized by a thickness of 4-5 mm, a degree of filling up to 50% and universal performance characteristics;
Highly filled coatings(average thicknesses are 4-8 mm, but can reach 20 mm) are characterized by a degree of filling up to 90%, which determines their long-term resistance to high mechanical loads.

Polymer flooring: advantages and disadvantages

Despite the unpretentiousness of the polymer coating, it still remains one of the most aesthetic options for arranging the floor in any room. From the name it follows that the composition of the floor covering includes polymaterials included in it in the form of a liquid and subjected to polymerization during its technological processing. Thanks to this feature, the surface is perfectly flat and uniform.

Important! Due to the fast polymerization of the composition, the operation of the floors can be carried out within a short period of time from the moment of laying the floor covering.

Advantages of polymer coating:

High elasticity, which makes the flooring resistant to intense shock loads;
Resistant to constant exposure low temperatures, thanks to which polymer compositions can be used for arranging flooring in outdoor trading areas, for laying flooring on the territory commercial organizations for various purposes, as well as in freezers;
High wear resistance, which determines the ability to withstand long-term mechanical loads without loss of original performance;
Resistant to high humidity and chemicals;
Long service life, which can exceed 40 years;
Unpretentiousness in leaving - cleaning of a floor covering can be carried out by means of ordinary water, without use of special cleaners;
Non-toxicity and fire safety;
High aesthetic characteristics, lack of seams and absolute smoothness of the coating. The polymer coating acquires additional surface decorativeness and a unique special effect due to 3D varnish. Furthermore, modern manufacturers offer a polymer coating with a textured surface and an original pattern.

Disadvantages of polymer coating:

In the process of surface preparation, which takes a fairly long time, difficulties can be encountered;
The polymer coating is characterized by a long service life, during which it can become morally obsolete or annoy the owner;
Difficulties encountered in the process of removing the floor covering;
Vapor resistance of polymer flooring;
Polymer flooring refers to a fairly high price category, which is due to the high cost of the component materials that make up the polymer coating;
Despite the relevance of the previous paragraph, there are also cheaper varieties of polymer coating on the market, however, they are prone to rapid yellowing due to ultraviolet radiation;
Compared with traditional flooring, resin material design is not large enough;
In the process of repairing a polymer floor covering, difficulties may arise, since increased aesthetic requirements are imposed on it. Thus, if you are faced with the need for local repairs, it will be difficult to select the required color scheme.

Important! Polymer floors intended for laying on a concrete base and characterized by the absence of active waterproofing will soon begin to peel off due to evaporation ground water that rise through the natural capillaries of concrete slabs.

The device of polymer floor coverings: a step-by-step guide

In order to avoid the repair of the polymer floor covering, ensuring it a long service life, in the process of arranging the self-leveling floor, it is necessary to strictly follow the recommendations of specialists. If you follow all technological stages flooring devices, this process seems pretty easy to you.

Materials and tools for arranging a self-leveling floor

To equip a self-leveling floor, you will need:

Several plastic buckets with a volume of 30 liters;
A drill equipped with a stirrer and characterized by a small number of revolutions (no more than 300);

Notched roller and spatula;
Special needle roller designed to remove air bubbles. Required amount tools is determined by the area of \u200b\u200bthe room - an average of 40 square meters. m of the room will require one roller;
Squeegee with an adjustable gap, which will be required to evenly distribute the mixture on the surface;
Paint shoes, which will be required to move on a freshly poured floor;
A solvent with which you will clean all tools after work.

Foundation preparation is a crucial stage in the arrangement of the self-leveling floor

It is important to carefully consider this stage of flooring, because otherwise, if there are uneven bases, this will cause deformations of the floor covering and its subsequent damage. Technology preparatory work from the initial state of the base and the material from which it is made.

Preparation of the concrete base

Carry out a moisture test of the base, which should not exceed 4%;
If you have laid a new foundation, at least 28 days must pass before laying the self-leveling floor;
If you are dealing with an old concrete base, remove the old flooring, clean the surface of dirt, removing the remnants of mastic, paint, glue and oil stains;
Clean the concrete base from dust and repair all existing bumps, cracks and potholes with mortar with the addition of resin. If small cracks and breaks are found, it is recommended to use an adhesive solution. To mask and remove the smallest defects, use a grinder;
Using a horizontal stick-level, check the levelness of the surface.

Wooden base preparation

Check the humidity of the wooden base - it should not exceed 10%;
Remove the skirting boards, as new ones will be installed during the installation of the flooring;
Clean the surface of varnish, paint and glue with a spatula, metal brush or grinder;
Open the cracks and clean the floor with sandpaper, which will increase the adhesion of the surface;
Using an industrial vacuum cleaner, remove the remaining dust and degrease the surface with a cleaning powder;
Level the wood floor with cement screed or patch cracks with mortar.

The air temperature in the room where the floor will be poured should be from +5 to +25 degrees, and the humidity should not exceed 60%.
Any mixture for pouring polymer flooring in a garage or any other room is a two-component one, and therefore, they must be mixed in a clean bucket using an electric drill.
The application of the polymer mixture must be carried out only after the final drying of the primer, which will take about a day. It is recommended to start pouring the mixture from the highest point of the surface. To do this, the prepared polymer mixture is poured onto a primed base and spread over the entire surface of the base using a toothed roller. If bubbles form, remove them using a spiked roller.
The thickness of the coating on average should not exceed 1.5 mm, however, in individual cases it can be increased up to 5 mm.
To move across the floor, you will need paint shoes. After waiting for the final drying of the first layer, proceed to applying the second, after which, after 12 hours, apply a layer of varnish.

Technology of pouring polymer flooring

Pour the prepared solution onto the floor surface and spread it over the entire area. To make the distribution more uniform, each subsequent portion of the mixture is distributed near the previous one with a wide spatula. To adjust the thickness of the applied mixture, use a squeegee;
To remove air bubbles that have fallen into the solution, use a spiked roller by passing it over the floor surface;
Pour the next portion of the solution and smooth it, thus filling the coating over the entire floor area;

When finished, cover the floor surface plastic wrap, which will prevent dust from entering the floor that has not yet hardened, and will also make drying more uniform;
To boost decorative characteristics polymer coating, apply polyurethane varnish on its surface.

Features of arranging a 3D floor

A decorative option for a polymer floor covering is a 3D floor, which is three-layer construction, which includes three layers:

base layer;
Picture;
The final one is the protective layer.

The installation of a 3D coating is generally no different from the installation of a traditional polymer floor covering. The first stage of installation also consists in preparing the base and is carried out in accordance with the above recommendations for self-leveling floors;
For the arrangement of the base layer, it is recommended to use a polymer coating or floor screed. It is important to determine the features of the future decor. Depending on whether it will be small or large, the color scheme of the polymer coating is selected. If the decor is characterized by the presence of a small pattern, the polymer coating will act as a background surface, which necessitates a responsible attitude to the selection of a color palette;
One of the most important stages is drawing an image. If you plan to paste the selected picture, select the image in such a way that its dimensions slightly exceed the floor area;
Sticking the picture is carried out only on an ideal flat surface. At the same time, make sure that not a single bubble forms during the gluing process;

Important! To apply a complex artistic drawing, use the services of professional artists.

To fix the resulting image, apply a thin layer of varnish.
The thickness of the final protective layer should not exceed 0.5 mm. For its application, as in the case of a traditional self-leveling floor, a toothed roller is used, and a needle roller is used to smooth the resulting air bubbles. The operation of the polymer 3D floor can be carried out in a week.

Important! One of the biggest challenges you may face when decorating a 3D floor is blistering. Their appearance may be due to factors such as high humidity coatings, poor mixing of components and improper preparation of the mixture. To avoid this, it is recommended to use an electric drill equipped with a mixer attachment to mix the components of the mixture. To make sure that the humidity of the concrete surface is at an optimal level, use plastic wrap, laying it on the concrete and sticking it with tape. If after three days the film remains dry, you can start pouring the mixture.

Precautions in the process of arranging a self-leveling floor

Use protective goggles and gloves during work;
Avoid getting the mixture on open areas skin, as this may cause irritation;
Take care of effective ventilation in the room where the pouring will take place, since the mixture has a sharp specific smell;
If you want to give the floor a shine, use special chemicals;
Normal cleaning of dust and dirt can be done with running water.

Polymer floors have gained considerable popularity due to their excellent technical specifications and beautiful performance. Such a coating can be installed not only in industrial premises, but also in private houses and apartments. Making polymer floors with your own hands is not very easy, but if you follow all the stages of work accurately, you will definitely get a high-quality smooth coating that will last for many years.

What base is suitable for pouring?

You can make a polymer floor covering with your own hands on almost any type of base. But each of them has its own device features:

Wooden base. To make a fill on a wooden floor, you first have to level it. Usually, an electric planer is used for this. If necessary, failed logs should be replaced, and all the gaps between them should be treated with adhesive;
Concrete base. If there are significant irregularities on the coating, before pouring a clean floor, it is necessary to make a screed. At the same time, the reliability of the polymer coating on concrete floor will always be higher than wooden base;
Tile. If necessary polymer composition can even be poured onto tiles. It must be well fixed, so before starting work, each of the tiles must be tapped. In order for the adhesion of the polymer mixture to the tile to be high, it is desirable to treat the base with emery.

Preparation of the wooden base

Of course, making the self-leveling coating yourself is quite problematic, since you will have to do a lot of work to prepare the base for pouring the polymer.

First you need to make sure that the warping is even. Check this with the usual level. A tolerance of 4 mm is considered. To make polymer self-leveling floors with your own hands on a wooden base, you must:

Dismantle all skirting boards;
Clean off the old coating: varnish, paint, adhesive composition. For this you can use grinder. If you don't have one, use a regular spatula and metal brushes;
Be sure to take into account the humidity of the ceiling, it should not exceed 10%;
Find and process all defects: chips, dents, cracks and cracks. All existing flaws must be sanded sandpaper;
Clean the base construction debris and dust;
Then degrease the coating using scouring powders;
Next, treat the defects with special building compounds.

Preparing the concrete base

If you are going to mount the coating on a concrete base, you will have to perform the following preparatory steps:

Measure humidity, it should not be higher than 4%;
Then be sure to check the compressive strength of concrete, the indicator should be above 20 MPa;
If the concrete base was poured recently, it is possible to carry out work on the installation of the polymer mixture no earlier than after 25-28 days;
Remove the old covering from the floor;
Remove any contaminants from the surface: mastic, oil and glue stains, varnish and paint;
Clean the surface of debris;
Fill cracks and dents with resin mortar;
Treat small cracks and crevices with adhesive;
Level the base with a grinder;
Then check the evenness of the floor using a level.

To level the surface, it is best to use leveling mixtures, which are made on the basis of special binders. And remember that any coating must be strong, dry, clean and solid, without any cracks. If you pour the polymer composition on a flexible base, the self-leveling floor will not last long.

Padding

Before you make a polymer floor with your own hands, be sure to prime the surface. This will increase the adhesion of the base to the polymer. To close all the pores on the coating, it is necessary to apply the primer several times. handle concrete surface best of all two-component mixtures with mineral fillers.

Priming rules:

The base must be impregnated with a primer in a well-ventilated area;
The composition should be applied with wide brushes or rollers;
The next layer of primer must be applied after the previous one has completely dried;
You can pour the polymer mixture onto the base one day after pre-treatment floors with a primer.

Dilution of dry polymer mixture

Typically, polymer floor mixtures are divided into two components, which are in two containers. To dilute the composition, you need:

Take a deep container for mixing the components;
Mix the compositions according to the proportions indicated in the instructions;
To obtain a homogeneous mass, mix the emulsion well using a construction mixer;
Since the polymer begins to harden very quickly, it must be used immediately after dilution.

Important! Please note that during the mixing of the components, a reaction occurs, as a result of which heat is released. So that the quality of the self-leveling floor does not change, be sure to place the container with the composition in another container with cold water.

Filling the floor

Now you need to mount the bulk polymer coating on the floor. This process is very responsible, so try to clearly follow all the steps:

Pouring composition on small plot straighten it out immediately. To do this, use a doctor blade;
When you apply the emulsion, go over the surface with a spiked roller, then no air bubbles form on the floor;
The layer thickness should not be less than 1 mm, otherwise the surface will be fragile;
When the coating is completely dry (from several hours to several days), treat the surface with polyurethane varnish.

Important! To produce a high-quality fill, it is desirable that there is no draft and temperature difference in the room. These factors can further affect the life of the coating. It is desirable that the temperature in the room was not lower than 10 degrees.

The video shows in more detail all the stages of the work on pouring the polymer floor.

Installation of a polymer coating is a labor-intensive process that requires high-quality performance of all stages of work. If you manage to competently implement the entire range of work in compliance with the pouring technology, appearance The floor covering will not change even after prolonged use.

In recent years, the demand for polymer floors has increased several times. Such popularity of the material is due to good technical and decorative performance of the coating. It is quite simple to equip polymer floors with your own hands, if you strictly follow the recommendations of experienced professionals, which are presented below.

General information about polymer blends

The bulk coating is a polymer composition that is used as finishing draft base. It can be laid on mineral, wood, ceramic and even metal surfaces. For residential premises, polyurethane mixtures are most often used, since they have good aesthetic characteristics, as well as excellent thermal insulation.

All types of finishing bulk solutions are divided into two large categories:

Leveling - applied and leveled by hand with a spatula and spiked roller;
Self leveling- solutions that are liquid in consistency, which spread over the coating with little or no auxiliary tools.

The thickness of the laid "liquid" coating can vary from 1 to 9 mm. According to many experienced craftsmen, for residential premises, a layer of 1.5-3 mm will be optimal.

Preparatory stage

How to make a bulk polymer coating on the floor yourself? Before proceeding with the direct pouring of the polyurethane solution, it is necessary to prepare a rough base. The main requirement that applies to coatings for the installation of a self-leveling floor is evenness. To check the "horizontal", use a fairly long ruler and a building level. If the height difference per m2 exceeds 3-4 mm, you will have to think about additional alignment of the base.

How to prepare the base? Depending on the type rough coating There are several ways to prepare the floor, namely:

For concrete pavements
- Humidity cement screed should not exceed 4%;
- Using the Schmidt hammer and Dean's apparatus, it is necessary to find out the strength of the base for separation - at least 1.5-2 MPa and the compressive strength of the material - at least 20-23 MPa;
- When arranging a new screed, it is desirable that its “age” be at least 27-30 days;
- When repairing an old floor, you need to free the base from paint, the old finish, glue and stains;
- After that, potholes and chips are repaired in the screed, bumps and cracks are eliminated;
- Minor irregularities can be eliminated with a grinder, and cracks with an adhesive solution;
- Then using building level it is necessary to check again the "horizontality" of the concrete screed.
For wood flooring
- AT this case humidity allowed wooden floors, log and plywood in 10%;
- The rough floor is cleaned of the old coating and baseboards, varnish, paint and oil stains;
- For high-quality stripping it is advisable to use a metal scraper, grinder and spatula;
- The cracks on the surface are cleaned with sandpaper, and then puttied;
- If possible, the floor is leveled with a cement screed or plywood sheets different thickness.
For ceramic coatings
- You can also equip polymer self-leveling floors on ceramic tiles, but, first of all, you need to check the coating for loose elements;
- If in the process of tapping the tile a dull echo is heard, the torn off tile must be removed and, having treated with glue, fixed again on the coating;
- Ceramics are degreased and treated with a primer, after which all tile joints are puttied.

Preparation of polymer solution

One of the most important stages of work is the preparation. bulk mixture. The "spreadability" of the solution during the pouring process will depend on the quality of the batch and consistency. In order to properly prepare the mixture, it is advisable to focus not on the recommendations of the "experienced", but on the instructions provided by the manufacturer on the package.

How to make a quality solution?

Pour water into the prepared container, according to the instructions;
The dry polymer mixture is then added;
Knead the liquid mass for at least 10 minutes with construction mixer or drills with a nozzle in the form of a butterfly;
The prepared solution should be free of any lumps and inhomogeneities.

How to check if the mixture has been prepared correctly? For those who are faced with the process of pouring a polymer floor for the first time, the “spreadability” test will be useful. It will allow you to determine whether you did the batch correctly or not:

cut off small plastic cover bottom;
Install it on the floor and pour the polymer composition inside;
Carefully lift the lid;
If the mixture spreads evenly and forms something like glass surface, you prepared the solution correctly.

How much mixture is needed?

One of the main issues in the arrangement of the self-leveling floor is the calculation the right amount solution. On average, no more than 500-600 g of the mixture will be required to process m2 of a well-leveled base. In this case, the thickness of the "liquid" layer will be approximately 1 mm.

For more exact definition the required amount of material, you can use the following expression: y + (y1-y2) / 2 \u003d x, where:

х is the coating thickness;
y1 is the distance from the highest marking point to the base;
y2 - distance from the lowest marking point to the base;
y is the allowable thickness of the polymer mixture indicated on the package.

Floor marking and wall covering

How to make a polymer floor with your own hands? Before pouring the solution, it is necessary to mark the base. This is done in order to install pendulums that control the "horizontality" of the applied mixture. Moreover, even if using self-levelling compounds, they still have to be directed to the corners of the room.

How is markup done?

On the surface of the black floor, pendulums are installed at a distance of about 1 m from each other;
When installing the pendulum near a wall, the minimum distance should be at least 10-15 cm.

So that during operation top coat not cracked, it is desirable to glue around the perimeter of the entire room damper tape. Even in the case of a linear expansion, polymer materials they will not “press” on the wall, which will not lead to their deformation. The width of the tape should vary between 7 and 10 cm.

Application of the polymer solution

About a day after priming the subfloor, a polyurethane solution is poured. How to fill?

The finished solution is poured onto the coating from a bucket at a small height from the floor;
To level the mixture, a sufficiently wide spatula is used, and the layer thickness is regulated with a squeegee;
The next operation for pouring the solution is done close to the treated area, in order to obtain a seamless monolithic coating as a result;
The remaining amount of solution is poured in the same way;
To prevent air bubbles from remaining in the coating, it is rolled with a spiked roller;
At the final stage, experts recommend covering the floor with polyethylene to avoid uneven drying of the solution and its cracking.

More application process polyurethane composition on the prepared base is shown in the video material. To protect the coating from mechanical impact, an additional layer of varnish is applied over the solution.

Manufacturers overview

For high-quality arrangement of polymer floors, professionals recommend using building mixtures only trusted manufacturers. Among the best of them are:

Litokol- Italian company releases dry polymer blends high strength and wear resistance. They include modifying substances that improve the physical and mechanical properties of the coating;
Ivsi is one of the best manufacturers“liquid” floors add fractional sand and mineral components to the mixture, due to which the solution consumption is significantly reduced;
Bergauf - the company specializes in the production of coatings with improved adhesion (more than 1.2 MPa). Acrylic and polymer additives, which are part of the raw material, improve the spreadability of the solution over the coating. Enough liquid formulations penetrate into the smallest pores on the base and create a perfectly even polymer coating.
