Today, self-leveling floors are gaining great popularity. There is a huge variety of such coatings on the construction market. That's just which one to choose, how much the mixture will need, what floor thickness is needed and how to save money in this matter, not everyone knows. Having learned about the correct technologies and the intricacies of its pouring, you can make a high-quality coating without spending your entire budget.

In order to choose the right coverage, it is important to know what they are and what kind of room they are intended for. A sales assistant cannot always help you make the right decision, so let's take a look at what types of self-leveling floors are and what they are intended for:

Polymer there are epoxy, methyl methacrylate, polyurethane. Polymer floors are versatile flooring with excellent mechanical and decorative properties. That is why the range of their application is very large. They have excellent self-leveling properties. They can be used in residential, industrial and civil construction: in garages, warehouses, parking lots, shopping pavilions, in the medical and food industries, in residential buildings and apartments, sports facilities. The thickness of such a floor can be from 2 to 40 mm

Methyl methacrylic floors are also called industrial floors. This coating is suitable for rooms with high mechanical stress. Most often, such a mixture is used for floors in industrial workshops, parking lots, garages, warehouses, since it is resistant to temperature extremes, vibrations, mechanical stress, water and aggressive influences. The coating thickness is usually 4-6 mm.

The area of ​​application of polyurethane floors is quite wide - the food industry (dairies, bakeries, meat processing shops, breweries, warehouses), the chemical industry, public places, parking lots. Such a floor is poured with a thickness of 5 mm.

Epoxy floors are classified as polymer compositions, but they do not differ from them in their versatility and breadth of application. They are also used in industrial and residential construction. The optimum layer of this coating is 2.5 mm.

Mineral… Mineral floors are used in rooms with moderate humidity, used for the final leveling of a very curved surface, for arranging heated floors. Accordingly, this type is best used in residential construction. Basically, mineral compositions are used as a base or middle layer due to the cheapness of materials, for example, under tiles and floating floors. Mineral floors are available in various thicknesses

Acrylic-cement. Acrylic-cement coatings are an industrial classic mixture, which is poured in rooms where the load on abrasion is increased. Such premises include warehouses, "wet" industries, car services, garages. The thickness of acrylic cement is from 10 to 20 mm

Self-leveling cement-polymer. Self-leveling cement-polymer composition is used for repair work on magnesite, ceramic and wood surfaces. This is the most common type of coating used worldwide. The coating thickness can be up to 5 cm

Antibacterial. Antibacterial coatings are relevant for food production, restaurants, kindergartens, and other public facilities. They are also used in rooms with high humidity

According to the thickness of the coating, they are divided into:

  1. Thin-layer - the thickness is less than 1 mm;
  2. Mortars with a middle layer - up to 5 mm thick;
  3. Highly filled coatings - up to 8 mm thick.

Installation

Each coating has its own unique composition, due to this, the characteristics of the mixture are formed. The epoxy mixture contains resin, which is characterized by strength and durability. This coating is of several types:

  • thin-layer - the thickness of the filling is up to 1 mm;
  • bulk - more than 1 mm thick;
  • quartz-filled - thickness is more than 1 mm, but its main difference is a layer of quartz sand.

Methyl methacrylate floors are made from flexible methyl methacrylic polymers and copolymers with the addition of quartz sand and filler. Such a composition dries up within 15 minutes, it is easily repaired without breaking the tightness. It is a thin-layer compound with a thickness of 2.5 mm to 4 cm.

The polyurethane mixture consists of urethane, which is formed by the reaction between polyol and isocyanate. Thanks to this reaction, it has high chemical and thermal stability. Distinguish:

  • polyurethane floors;
  • polyurethane-cement floors.

The technology of filling the floor with a polymer mixture requires compliance with the following steps:

  1. Preparation of the work surface. This stage implies cleaning from debris, grease, dirt. And also it is necessary to level the floor from roughness.
  2. Padding. An important step that improves the adhesion of the layers.
  3. Base coat application and decoration. The polymer composition is applied to a flat surface with the required layer. Wait for about 10 minutes to flatten the surface. The drying process takes about 5-8 hours. The last decorative layer is applied only 5 days after complete drying.

The thickness of the polymer-based coating should be between 2.5 and 5 mm.

The acrylic-cement coating contains high quality cement, polyacrylic copolymers and a special filler. This mixture of substances guarantees durability and resistance to moisture. The minimum thickness is 10 mm, and the maximum thickness is 20 mm. When filling with such a composition, you can forget about waterproofing.

The installation technology of such a floor is as follows:

  1. Sub-floor preparation. It is important to remove the protrusions and fill up the gaps. Remove all small debris with a vacuum cleaner.
  2. Surface primer for increased adhesion.
  3. Application and leveling of the mortar with a spatula. It is important to work quickly as the mixture will polymerize within 20 minutes.
  4. To release excess air, the mixture is rolled with a needle roller.
  5. After a couple of hours, the surface is covered with a finishing layer (varnish, resin).

The mineral coating consists of sand, cement, expanded clay concrete. It can also be used for thermal insulation under the mineral composition of expanded polystyrene. Subsequently, such a floor will require a topcoat. Allocate:

  • Base layer - 10 to 80 mm thick, dries for about 12 hours;
  • Middle layer - thickness from 7 to 30 mm, drying period - about 4 hours;
  • Finishing layer - 3-10 mm, dries in 4 hours.

Self-leveling cement-polymer composition has good adhesion to the base layer. This is one of the types of concrete coating, which includes cement mixtures, quartz sand, pigment and polymer additives. The optimum thickness can be up to 5 cm. It can have a matte and glossy surface.

Antibacterial floors are a durable coating system that gets rid of mold, mildew and pathogens.

The thickness of the self-leveling floor depends on the load that the floor covering will withstand. In residential premises, it will be 1.5 mm. This will be enough not to remember the renovation for many years. But it is important to consider for what purpose this or that room will be used. The choice of material and layer thickness also depends on this.

On average, for a standard living space, the thickness can be from 2.5 to 5 mm.

A 5 mm thick polyurethane material may be suitable for the kitchen, since it is there that heavy objects often fall on the floor, and this coating has elastic properties.

Epoxies are perfect for the bathroom. This is due to its high resistance to moisture. The layer thickness will be about 1.5-2.5 mm.

Methyl methacrylate compounds are suitable for the hallway and living room. The layer of material is 3-4 mm.

But at industrial facilities, the self-leveling floor layer can vary within 10-15 cm, since the load on it in such rooms is much greater. Therefore, saving on material, the coating will quickly come out of the layer.

To determine how much mix you need, you need to consider the thickness of the coating. For example, if the total area of ​​the premises is 50 sq. meters, and the thickness of the filling surface is 2 mm, then you need to purchase about 100 liters of material. If the mixture is denser, then 150 liters. If you want to reduce consumption, use additives to increase the volume of the material.

If the thickness of the self-leveling floor is less or more than the permissible value, then its service life will be significantly reduced.

Tips from professional builders

To get a quality floor covering at a low cost, you can use the following techniques:

  • For slightly curved surfaces, you can use a sander to smooth out roughness and unevenness. This technique will allow you to save on the purchase of building material.
  • In order not to buy a primer, you can make it yourself. This will require a small amount of self-leveling floor mixture and water.
  • With large differences, it is better to use concrete solutions for leveling instead of a bulk composition.
