Arrangement of floors is an important and time-consuming stage in construction and repair. Quality flooring should meet several criteria. Initially, they must be durable and very durable. In addition, it is important to have aesthetic characteristics, smoothness of the coating.
To achieve a positive result of the repair process, special attention should be given to preparing the substrate. Under the floor basis is meant a floor screed, which is a thin layer of a special mixture. Directly on it in the future, the installation of the selected floor covering will be carried out.
It should be remembered that in order to implement the correct tightening, it is necessary to prepare a high-quality mixture for floor screeding. Which, by the way, should perfectly match the current method.
The mixture for floor screed can be either manufactured independently or purchased in finished form on the construction market presented by different manufacturers. Typically, this finished formulation contains an ideal concentration of materials such as sand, cement and plasticizers. Obviously, the finished floor screed mix is more convenient to use, but sometimes it requires a special concentration of the materials used. Therefore, in some cases, the mixture for floor screeds is prepared directly on construction sites. Basically, the main materials for making the mixture are cement and sand. Modern professionals (in this type of activity) add to the composition of certain plasticizers, which make it possible to simplify the process of contraction, and also provide more rapid congealing. Often used the ratio of cement and sand - 1: 3. To prepare a quality mixture for floor screed, it is necessary to take into account a very important detail, which consists in the presence of a clear correspondence of the amount of ingredients used. It is compliance with these rules that guarantees a positive end result.
Dry mix for floor screeds are made on the basis of cement and gypsum. It perfectly ensures the leveling of the surface of the flooring, and, if necessary, with it, you can make the necessary slope and hide the pipe or heating in the floor.
An important factor is the process of adding water. In this case, you need to be very careful. If there is a lack of water, the cement can quickly crack, and if there is an excess, numerous chips and defects can form. So the amount of water should be accurate: no more, no less. Adding a certain type of plasticizer will avoid some mistakes in the preparation of solutions. For this reason, many modern specialists use high-quality plasticizers, which are able to give the material special strength and prevent various defects in the mixture.
