The best solution is self-leveling floors

Self-leveling floors is a dry mix, the basis of which is cement with the addition of mineral and chemical components. It is used for the purpose of leveling the base for various types of coatings. In order to obtain the maximum result from the use of self-leveling floors, it is necessary to familiarize yourself with the characteristics of these mixtures, as well as the rules for their use.

Self-leveling floors exist in two types. The first of them is a gypsum-cement mixture, which is intended for use in places with large differences in altitude (from 20 to 80 mm). Self-leveling floors of this type require absolute absence of moisture in the room, as its effect leads to their softening and increase in volume. Approximately in a day on such a floor you can already walk, but it is recommended not to lay a coating earlier than a week. Possessing excellent thermal conductivity, self-leveling floors of this kind are an ideal solution for the installation of heated floors.

Cemented self-leveling floors of the second type are used on bases with smaller differences (from 2 to 30 mm). These are self-leveling floors, the technology of which allows them to be used for the final leveling of surfaces such as concrete and sand-cement. Due to the content of modifiers, mineral and polymer additives, self-leveling floors of this kind have the highest adhesion to the substrate. This floor has excellent plasticity, good frost resistance, has a low degree of shrinkage.

Self- leveling self - leveling floors based on cement are more reliable, since the reinforcing fibers that make up their composition counteract the appearance of microcracks. The surface of the floor allows you to walk on it after five hours, but it is recommended not to do it throughout the day. It is possible to cover the coating, of course, after four to five days, but according to the recommendations of specialists it will be better to do this in a week.

Substrate preparation

Preparation of the substrate includes not only cleaning the surface of various types of debris, but also removing dust with a primer. It is necessary to pay special attention to the presence of traces of old cement, as well as different spots (oil, bitumen), as they can further lead to disruption of the integrity of the floor. In the presence of deep cracks on the surface for at least 24 hours, they must be eliminated with a special mixture, the same mixture needs to be covered with panel joints and joint elements and then primed these places.

Mix preparation

When spreading a dry mixture, special attention should be given to the dosage of water, since with a large amount of it, the solution will be "weak" and after drying it will give cracks. If there is not enough water with the mixture it will be difficult to work, as it will have poor plasticity. The dry mixture must be added to the water, and not vice versa. For the convenience of preparing the mixture, you can use an electric drill with a specially designed nozzle. Then you should hold it for five minutes to ensure that the solution has fully gained its qualities, and you can proceed to flood the floors.

Filling of floors

Make the fill from the lowest level and output to the highest point of the room. The mixture seizes for about 30-40 minutes, during this time it is necessary to remove air bubbles and to level the total area. This can be done with a special platen roller.

Since different manufacturers produce products with different mixtures, it is necessary to carefully study the recommendations that are given on the packaging of a mixture for a self-leveling floor.
