The arrangement of floors is an important and time-consuming step in the construction and repair. Quality flooring must meet several criteria. Initially, they must be durable and very strong. In addition, the presence of aesthetic characteristics, evenness of the coating is important.
To achieve a positive result of the repair process, special attention should be paid to the preparation of the base. Under the base of the floor means floor screed, which is a thin layer of a special mixture. Directly on it, further laying of the selected floor covering will be carried out.
It should be remembered that in order to achieve proper contraction, it is necessary to prepare a high-quality mixture for screeding the floor. Which, by the way, should perfectly suit the current technique.
The mixture for screed can be either made independently or purchased ready-made in the construction market, presented by different manufacturers. Usually in this finished composition contains the ideal concentration of materials such as sand, cement and plasticizers.
It is obvious that the finished mixture for floor screed is more convenient to use, but still sometimes it requires a special concentration of the materials used. Therefore, in some cases, a
mixture for screed is prepared directly at construction sites.
Basically, the main materials for the manufacture of the mixture are cement and sand. Modern professionals (in this type of activity) add certain plasticizers to the composition, making it easier to pull together, as well as providing faster solidification. Often use the ratio of cement and sand - 1: 3. In order to prepare a high-quality mixture for screed, it is necessary to take into account a very important detail, which consists in the presence of a clear correspondence to the amount of ingredients used. It is compliance with these rules that guarantees a positive end result.
The dry mix for floor screed is made on the basis of cement and gypsum. It perfectly provides leveling of the surface of the floor covering, and also, if necessary, it can be used to make the necessary slope and hide the pipeline or heating in the floor.
An important factor is the process of adding water. In this case, you must be very careful. If there is a lack of water, then the cement may crack quickly, and if there is an excess of it, numerous chips and defects can form. So the amount of water must be accurate: no more, no less.
The addition of a certain type of plasticizer will avoid some errors in the preparation of solutions. For this reason, many modern experts use high-quality plasticizers, which are able to give the material special strength and prevent various defects in the mixture.
