One of the main stages of black repair in a new apartment is the preparation of the floor for the subsequent laying of the finish flooring. The main task that is to be completed during the installation of the draft floor is to create the most even surface. Of course, a long service life is needed and, if possible, additional heat and soundproof properties. In addition, floor leveling should not be too expensive, because the cost of repairs will already be significant.
One of the most popular options for creating a black floor is a cement screed. Perhaps it is the cement screed that meets all the requirements that we talked about above. The cement screed is universal and suitable for the subsequent laying of any type of flooring — laminate, linoleum, parquet, carpet, traffic jams and tiles. The cement screed is convenient if you plan to make warm floors. The cement screed, unlike a dry screed, is absolutely not afraid of water. Therefore, it is best suited for use in zones with high humidity. Among the advantages of the cement screed, the strength, durability and wear resistance can be noted, even if the thickness of the screed is small. In addition, the cement screed is one of the cheapest.
Among the shortcomings of the cement screed, it can be noted that such a screed dries for a long time. In addition, with the help of a cement screed, it is impossible to make a very thin layer of the black floor. Usually recommended minimum screed thickness — 4 centimeters. But in general, a cement screed is a really good option for a draft floor, and it is often used both in the repair of apartments and residential buildings, and for office, retail and industrial premises.
A cement screed is produced in the form of ready-made cement-sand mixtures, which immediately before starting work should be diluted with water. In addition to the cement and sand, the mixture may include additives that increase the strength or plasticity of the mixture, prevent its delay and cracking, accelerate hardening, and give the screed additional properties (for example, frost resistance).
The finished solution is applied to the floor, aligned by beacons and smoothed out. After drying to the finished floor, you can apply special protective polymer compositions. To work in the premises of a large area, special equipment can be used, which allows you to qualitatively make a cement screed in a short time.
