Concrete floor is an ideal base for any kind of floor covering. It gives the surface strength, durability, serves as an additional thermal insulation layer. In addition, it is available at a price, it is very easy to do it yourself.

First of all, it is necessary to carry out preparatory work: remove the plinth, remove the entire old flooring. If you have a big emptiness under the previous floors, then you need to be at the sand or earth. The fastened layer should be pretty loosen and tamper. If, on the contrary, there is no place to fill concrete, then such a space, a layer of 10 to 20 cm on the thickness of the concrete, it is necessary to release. And then consider the thickness of the screed 2-4 cm and the thickness of the new floor covering.

Next, the waterproofing material is stacked on the ground - rubberoid or dense film. As a warming layer, foam plates, minvatu, a layer of insulation can be used.

Now it is necessary with the help of a construction level and special construction "lighthouses" to expose the level of filling the floor. Do not forget to leave centimeters to the main floor level on the screed and floor covering itself. A mixture is used to set the beacons: cement, sand, alabaster, water in a ratio of 2 to 1 to 1 to 1.

The next stage is the preparation of the concrete itself. For a high-quality concrete mixture, cement must be taken at least M400, and better M500. And the sand, if you have the ability to choose, preferably river. You still need a concrete mixer and crushed stone.

If you want a layer of concrete, it is not so cold, then rubble can be replaced with a clay or polystyrene foam crumb - it will give the effect of warm floors. The mixture is prepared in a ratio of 1: 2: 2: 1 - respectively, cement, sand, crushed stone or clayjit and water.

Pour a concrete mix starting from the far from the corner of the room, buckets or straight from the concrete mixer, if you can install it in the room. Purchate the shovel, progressive movements, giving the opportunity to exit air from the mass. With the help of the Rules, the surface of the lighthouses.

When the fill of the floor is over, then you give him time to dry from 3 to 5 days. Then the pure screed is performed. It can be made with a pure cement mixture (cement, sand, water) or with the help of special self-leveling mixtures. Also give a day drying, then the surface is performed. For greater strength after 5-7 days, the surface of the floor is covered with primer.
Everything is easy and simple. Our floor is ready! Now it remains to put outdoor coverage. If you have time, then do not hurry to hold it. Experts recommend to give a month to dry out the concrete layer before putting carpet, and two months before laying parquet or parquet board.
