In order for the just laid flooring to be beautiful and even, it is important that the base under it is even. Much depends on the screed. Today, the screed can be not only concrete, but also half -dry, dry, using self -leveling mixtures, etc. D.
To prepare the concrete technology of the floor screed, first it is necessary to mix the solution, which includes: cement, sand, water. In order to facilitate the weight of the solution, expanded clay is often used. This is usually necessary if the room is not on the ground floor so as not to load the load -bearing walls. For quick drying to the solution, special plasticizers are added.
Lighthouses from a special aluminum profile are installed on the primed base. They can be fixed using a gypsum solution. Start from the corner and pour a small section of the room. The solution must be poured only to the top point of the lighthouses, which were installed strictly at the same level. The solution is leveled and the next portion is poured onto the unprocessed area of the floor.
So that cracks do not form in time on the surface of concrete in time, it must be sprayed with water on top. For those who are too lazy or not to knead the solution strictly by proportions, ready -made mixtures are sold in the store.
