Installation of cement-sand screeds
The function of a cement-concrete screed is to smooth out a brick, stone, concrete base. To perform the work, a solution is required, for the preparation of which it is necessary to use sand and cement of grade 300, with a ratio of 1: 3. In the finished dry mixture, the right amount, you need to pour the right amount of water, and bring it to the state of a thick dough. Split systems are very popular today.

The base for the cement-sand screed is removed dust and debris, and, if necessary, the surface is moistened with water and the geometric shape of the room is checked. Additional equipment and structures are used for leveling and professional laying of the mortar. Beacons are often used to mark the base. Also, marks from wooden slats are stacked, which serve to indicate the thickness of the mortar or a given floor level.
The main lighthouse is installed against the wall, after which the remaining lighthouses are installed with the help of rails and a level with a distance of up to two meters from each other. Between the installed intermediate and corner beacons, it is necessary to lay guide rails, and a cement-sand mortar is laid among them. In order for the solution to be even, it is necessary to use a crush.
Further, the slats are removed, and the holes in the screed are sealed with the same solution. There should be no cracks on the leveled and laid mortar. To obtain a smoother surface, after setting, the solution is rubbed with a large float..
