After that, it is necessary to determine the zero level, which is calculated using the water level. As a rule, experts recommend to beat the level once in all the areas designated under the screed - at a height of 1.5 m from the floor. This is done by placing first mark in any of the premises, and then mark the level on the walls of all rooms, using water level. Then, connect all the marks line, which acts as a single zero for all rooms.
Repair of apartments - floor screed provides a thorough training process that ensures a positive outcome of the further operation of the floor covering. Now should they sounded the distance to the floor, which were obtained after a mark of zero. Consequently, in the place where the distance is the smallest floor height is maximum.

At the end of the preparatory process, should be prepared under the fill, the existing subfloor. This is done by removing the old cover and thoroughly clean the base of the dirt and dust.

Then you need to put beacons - T-shaped metal guides that sit on a solution. Professionals who do screed floor - are advised to spread the solution in small portions. When installing the first guide should note the distance from the wall of 20cm, and then, fasten the other lighthouses in parallel with a 30-40cm. Remember that the length of the rule must be greater than the distance between beacons. Now we need to align the process of lighthouses, which operates a special level. Must not only align along the lighthouse, but also relative to each other. After the zero level has been reached in all positions, wait until solidification of the solution.
Next on the screed is a process of filling solution. This happens as follows: from the far side of the room fill with prepared solution to the space between the first two lighthouses and align the rule - is contractible in itself. Continue the process until a complete fill floors in all rooms.
