Everyone who knows at least a little in construction is known about pouring the floor with a cement mortar called screed and its significance for construction work. It is on how qualitatively this procedure will be performed by the further arrangement of the interior decoration of the room and the finish covering of the floor surface. The decorative flooring ideally fits on the base floor aligned with screed, while the screed itself should be made impeccably, for which in turn, a high -quality solution should be prepared. As a rule, when kneading the concrete mixture, the M400 cement is given preference, since its strength limit is the most suitable for this.
