Self-leveling floor with their hands

If you want to cover the floor with laminate, tile, carpet or any other topcoat, first it is necessary to ensure its evenness.Flat floor - a pledge of "longevity" of any coating.If we neglect this point, it would soon begin to grind your laminate, linoleum crack and rub off, and will depart from the tile surface.In this case, to help solve the problem of self-leveling floor mix.

Features mixtures

Today, manufacturers of building materials offer a wide selection of assorted self-leveling compounds for floors.The mixture itself is a special solution, the composition of which allows it independently to spread over the surface of the subfloor, thereby forming a flat and smooth surface.

self-leveling compounds have a number of advantages:

  • ease of operation;
  • fastest time work;
  • maximizing the strength of the coating;
  • a high level of plasticity;
  • long-term operation of the screed;
  • frost and, as a result, an excellent floor insulation;
  • economy;
  • not dangerous to human and animal health.


self-leveling compounds are used only in cases of slight curvature of the floor when it is necessary to raise the level of no more than 2 centimeters.If you use them to correct the serious differences of heights, this pleasure will cost quite expensive, so the first line the large differences in using cheaper materials.

There are also general rules for the use of mixtures, which are extremely important to observe.Thus, half kg solution "closed" square meter of surface layer of 1 mm.On the bag mixture typically takes up to 6.5 liters of water.Some professionals prefer "not to waste time on trifles" and pour the maximum amount of water - 6.5 liters.With a liquid solution it is sometimes easier to work with.Consumption Self-leveling floor is determined on the basis of squaring the surface and the desired layer thickness.


All self-leveling flooring mixture can be divided into two main groups on the composition:

  • cement;
  • plaster.

addition to these basic components in the mixtures present in the dust particulate limestone or quartz sand.Depending on the purpose of the mixture fraction size may vary.Also used to create mixtures of different plasticizers, waterproof material, components for optimal adhesion to the surface, strength enhancers and substances that cause the mixture to flow and solidify quickly.

cement mixture

self-leveling cement mix for self-leveling floor are used for leveling of surfaces in all areas.They are convenient because they allow you to work at any temperature or humidity level.Tie layer of this mixture may vary from 2 to 50 mm.Drying rate is rather high and ranges from 3 to 5 hours depending on the thickness.


Naturally, the price of the Self-leveling floor cement mixture will be higher than gypsum.

Gypsum mixture

As has become clear, the cost of gypsum cement mixture slightly lower, but this is due to some limitations in the work.For example, plaster formulations is recommended to be used only in dry areas.For this reason, they are not suitable for leveling the floor in the bathroom or in the kitchen, because in contact with liquid plaster base becomes soft, swells and loses its strength.The maximum layer thickness should not exceed 1 cm, otherwise such coupler may simply crack.


sex Pouring


Before you begin pouring the floor, do some preparatory work - dilute solution according to the instructions on the packaging and clean the surface of the floor.To the mixture is flat and held tightly as possible, it is recommended not only to remove dust and debris, but also the remains of glue, varnish or paint from the floor.

Dissolve the powder from the package required amount of water and mix thoroughly.This can be done manually or with the help of the construction of the mixer.Remember that you can only fill the floors freshly mixed, so it is best to prepare the first floor, and then to prepare a composition for filling.If the mixture is still thickened before work, then again, dilute it with water does not work, and have to do everything again.

stages of the preparatory work:

  1. After you have removed debris, inspect the floor for the presence of cracks and holes.If any, they seal the diluted mixture with a spatula and allow to fully dry.
  2. Prime the floor surface, to ensure the best possible grip with self-leveling mixture.To save on the primer, you can use the same formula for floor leveling, divorced less than is needed to fill the main.
  3. If there are significant irregularities or Elevations align them in any suitable solution.For this purpose, perfect Vetonit 4000 or 5000.
  4. When all the cracks patched, and the primer is completely dry, you can begin to fill with a mixture of the sexes.

potting mix

necessary tools for the job:

  • bucket of 20 liters;
  • Building mixer;
  • wide spatula;
  • narrow spatula;
  • needle roller;
  • long handle for the roller;
  • gloves.

Since the self-leveling floor leveling fast curing, the casting should be done as quickly as possible.Ideally, it should take no more than 20 minutes, so if you are not confident in their abilities, or squaring the floor too much, it makes sense to divide the process into several stages, making as you go solution.


  • pour the solution on the floor;


  • using a wide spatula spread the mixture on the surface of the floor.To work with hard to reach areas in the corners and walls, use a narrow spatula;

putty knife

  • Push the needle roller with a long handle and rolled them to the surface self-leveling floor.This is done in order to maximize the leveled layer and bleed any air bubbles.If after setting the mixture remains inside the air, such a floor can not support heavy loads.


If you do everything according to instructions, then after a few days you can admire the beautiful solid surface.Often, one bag is designed for a single batch, which together with the water takes just a 20-liter bucket.It is not necessary to mix several buckets of the solution, because you can not manage to distribute it across the surface.

At its thinnest point the layer thickness must not be less than 5 mm.

Depending on the layer thickness, room temperature and humidity drying times may vary from two or three days and a half to two weeks.Again, a significant role played by the form of the mixture (cement / plaster).It is recommended to wait a little longer to be completely sure that the mixture is frozen, and only then proceed to the installation finish.

errors when pouring the floor

great reviews about the self-leveling liquid floors, reasonable cost, and ease of operation mixtures are forcing many inexperienced "home" artists run to the store and buy them for leveling floors in your home.But often new to this business allowed a number of errors, which affect the quality and durability of the floor.

Common mistakes when filling floor:

  • after you poured the mixture on the floor immediately help it to spread over the surface.Yes, there is the word "self-leveling" in the title, but if it were that easy, it would not build, and magic;
  • make sure that the mixture reaches to all corners and joints of walls, extending it to a narrow spatula;
  • correctly choose the needle valik- his teeth must be quite long, so that the rolling on the floor does not remain immersed in the mixture is still at least 1 mm each spike.For this purpose it is necessary to take into account the thickness of the layer and after that to buy the roller;
  • provide valve and think the height of the threshold, to a mixture of slopping over into the other room.Install additional fencing will not be superfluous, the more so that the degree of inclination of the floor may affect the level of the mixture in the "dangerous" places in the doorway;
  • before the job is done measuring height in the room.If the center of the room suddenly would bump that is not visible now, after pouring the floor it will be an unpleasant surprise.

Make Self-leveling floor with your hands is quite simple, if you follow the instructions precisely.A successful outcome of such a surface will last for many years, will provide excellent sound insulation and protection from the cold in the winter.

And finally answer a question that could not have arisen in the mind of the reader in the process of exploring the article "How to align the entire surface, and even get in the corners of the room from the doorway or something?".In order to easily move around has not yet had time to harden the surface, we suggest to use special construction spiked shoes or construct their own.
