What is a self-leveling floor leveler? Floor mix, which is better to choose- Review + Video Which self-leveling floor leveler is better. The service life and appearance of the floor largely depends on how smooth the surface is under it. Before proceeding with the restoration work, pay due attention to the repair of the slabs and high-quality leveling of the floor. A self-leveling floor leveler will help you cope with this task.

The base is poured with quick-drying solutions not only during major repairs and construction, but also during cosmetic repairs of the premises.

This article will help you learn how to choose the right leveling compound and how to apply it correctly.

General information

Functional features

Self-leveling self-leveling floor is used for screed and eliminate defects. In addition, it performs the following functions:

  • Eliminates defects and differences in height.
  • Assembling the sub floor and creating a top layer on it.
  • Creates a perfectly smooth surface.

  • Renovation of the old floor.

Interestingly that self-leveling floor leveler is easy to spread over the area of ​​the base, and is characterized by a fast curing time. After 5-6 hours, you can walk on this floor.

Varieties of mixtures by composition

Floor levelers are produced in bags, dry. They differ among themselves in composition (plaster, cement), and purpose (corrective, starting and finishing).

What is a self-leveling floor leveler? Floor mix, which is better to choose- Review + Video To cope with the installation of a screed from 2 to 5 cm, the cement composition that can be used for any type is ideal for you premises and purposes (universal). Sometimes microfibers are added to the mix to strengthen the concrete base and replace the reinforcement.

Gypsum mixtures are perfect for use in dry rooms, since the material itself absorbs moisture well and, if it is excessive, begins to swell.

With an increase in the volume of the base, the finishing flooring will begin to deteriorate and after a while may even lead to deformation of the walls. As an advantage, you can name the high strength of the walls and the ductility of the screed, which will not be more than 1 cm thick.

Important: If you want to get a stronger and more durable base, you will need add plasticizers to the finished composition.

Types of mixtures by purpose

Depending on where the mixtures will be used, they are divided into:

  1. Coarse starter floor leveler (self-leveling) in the form of a cement-based mixture. It is formulated with coarse particles to help increase toughness when applied in thick layers. They are used to eliminate tangible defects, they are also suitable for leveling bases with a large difference in height, they can replace the screed. There are compounds that are designed for a specific screed thickness.

    Thanks to the starter coat, you will be able to create a rough surface, which will then need to be covered with a finishing solution.

  2. Corrective compounds, which are used to level tiles or finished screed with small defects.
  3. The finishing compound, application of which to the base will guarantee the durability and beauty of the floor covering. The composition of such a coating includes gypsum with mineral components, cement and polymers, which will help form a homogeneous mass when dissolved in water.

Interestingly, that for the treatment of rooms with high levels of humidity, certain moisture-resistant formulations are used, which contain special polymer components.

Advantages of levelers

Although a self-leveling floor is several times more expensive than simple cement mortars, they have many advantages:

  • They can be used as a starting coat and as a finishing coat.
  • Dries quickly, no cracks form.
  • Can be used for over 20 years.
  • Provides a solid base and is also suitable for 3D fill.
  • Resistant to temperature extremes, plasticity of the composition.

  • There are compositions for pouring floors in rooms with high levels of humidity.

Please note, that if you urgently need to level the floor and start using it, then ideally use pride for the self-leveling floor. If on the label you find a particle size designation of 1.5 mm, then this composition is used only for ordinary screed.

A self-leveling floor leveler is considered as such if the size of its fraction is less than 0.

8 mm.

What to look for when choosing

Selection rules

To save on the purchase of this building material, you need to clearly define for yourself:

  • What thickness of the screed do you need, what are the differences in height and are there any defects on the base.
  • The room is dry or damp.
  • You need a cosmetic alignment of a maximum of 1 cm or the installation of a screed and elimination of pronounced defects.
  • What kind of finish you will use at the finish.

Hint: The finishing leveler is much more expensive than usual, so use only starter mix for roughing.

Characteristic of mixtures in comparison

Parameters Variety Description

Components of

Cement Cures slightly longer than similar solutions are suitable for use in rooms with high humidity levels.
Gypsum High drying speed, not suitable for rooms with high humidity levels.
polyurethane A plastic base is achieved, which will not crack under temperature extremes, vibrations and shock loads. It is used as a finishing layer, but before use, the surface should be well prepared
Cement-polyurethane When using such a solution, you will get a durable, strong and stable base with respect to stress and abrasion
Cement-acrylic Created on the basis of polymers, cement and acrylates, requires experience in pouring, you can make a high fill of the screed and not worry about cracking, create a strong, even and frost-resistant surface
Methyl methaacrylate (MMA) Such mixtures are made on based on methacrylic acid and methyl ester.

Distinctive features - fast solidification, high strength and resistance to moisture, can be used for places with high traffic (for example, at an industrial facility). In a liquid form, it is toxic, flammable, but after hardening it loses these properties.

Epoxy Created on the basis of epoxy resins with hardeners and plasticizers to achieve a transparent, durable and smooth surface. Can be used to create a 3D effect floor, there are formulations with anti-slip additives.

Coverage height

Self-leveling floor levelers To create the base layer.

Those containing many fillers I use it when leveling the base and creating a decorative layer.
finishing Only for the top layer.

Please note, that when choosing a mixture for a self-leveling floor in an unheated room, you should make a choice in favor of frost-resistant compounds. So, with a material consumption of a layer height of 0.1 cm, it will be from 800 to 2000 grams.

Self-leveling floor installation

What is a self-leveling floor leveler? Floor mix, which is better to choose- Review + Video When filling a self-leveling leveler requires careful surface preparation. Depending on what type of topcoat is used and in what condition the base is, we will select a mixture for starting and finishing.

Preparing the surface

The appearance and durability directly depends on how well the preparation is made, so you should approach this matter very responsibly.

The sequence is as follows:

  1. We remove the flooring, inspect the slab for defects: cracks, depressions, protruding reinforcement.
  2. We expand the edges of the cracks with a grinder, then we clean the exfoliated materials, the surface must be moistened and filled with a starting coating.

  3. If the expected screed layer is more than 2 cm, then a damper tape is applied along the perimeter of the walls. It will serve as a compensation for the joints, and will help prevent the solution from seeping to the neighbors below.

Attention! Priming the surface is very important before each leveling application. It will increase the strength of the compound and provide better adhesion.

We mark the floor

If the thickness of the leveling is more than 1 cm or in several layers, outline the height of the screed.

Correctly carry out the markup as follows:

  1. Based on we find the highest and lowest points. Draw a mark on the wall at a distance from the level below. Further along the perimeter, we mark the walls using a water or laser level.
  2. The marks on the walls should be connected with a horizontal line - that we get the floor projection.
  3. The guide beacons should be installed so that the upper part is located in one plane at the required height of the screed thickness.

Preparing the mortar

The self-leveling floor leveler should be poured no less than 6 hours after applying the primer layer. To obtain a high-quality and homogeneous solution, the dry mixture should be poured into water, which will be at room temperature. Dilute 25 kg of the mixture in 6 liters of water. Since with manual kneading you will not be able to make it homogeneous, you should prepare a drill with a nozzle or a construction mixer in advance.

The components are mixed in 2 passes:

  • First they are stirred for about 6-8 minutes.

  • Next, leave them for 5 minutes, so that they infuse and mix them again for 4 minutes.

Important: Prepare such a volume of solution that you can work out in 35-50 minutes, since with a larger amount it will begin to dry out and will no longer be suitable for creation self-leveling floor.

Pouring with an equalizer (coarse)

Begin pouring from the far corner between the beacons (ie stripes) and then the solution is distributed over the area. If you notice that voids have formed, add a little more mortar to this place and smooth it again, as a rule, you should drive it like on rails.

If more than one coat is required, allow each coat to dry for at least 24 hours.

After the mortar begins to set, fill the space with the mixture and level.

Important: In order to avoid uneven drying and the appearance of cracks on the surface, protect the room from drafts, artificial heating and sunlight.

Pouring with a leveler (finishing)

The finishing self-leveling floor leveler is used to obtain a perfectly flat surface. When pouring on such a floor, walk in studded paint shoes.

The surface on which the mortar will be applied must be even and have at least 2 coats of primer.

To prevent the mixture from leaking to neighbors, it is recommended to use a waterproofing material.The solution must be liquid, which means that you do not need beacons - it will be applied in one layer and will spread perfectly over the surface.

The area of ​​the room should be divided into zones, and each of these zones should be filled in 15 minutes. The solution should be poured from the far corner, after which it is leveled with a rule. We fill the plots in one run to the desired height, and then go through the solution with a needle roller to remove air bubbles.

The solution with polymers will harden in half an hour.

Results

Done! It remains only to protect the surface during drying from abrupt drying, drafts and mechanical damage. Polymer topcoat is applied not only for quality coverage but also for 3D images. If you decide to make this a reality, then remember that the layer of solution should not be less than 0.3-0.

4 cm. Thanks to the unique composition, you can create an original volumetric drawing.
