Waterproofing is done by plastic film. She laid on the floor and is attached only at the wall at 5 cm from the floor. Next you need to lay on the perimeter of the room strips of mineral wool or polyethylene over the layer of plastic film. This is done for quality of sound insulation and shock absorption.
You then lay the screed itself. Best of all, if it’s particles of expanded clay fraction from 1 to 5 mm. due to the difference in diameter they perfectly cover the surface of a smooth layer. For leveling layer, it is desirable again to use the beacons. The layer should be put in such a way as to leave margin of 2.5 cm between the leaf surfaces. The alignment starts from the farthest corner and ends near the entrance.
The surface of the dry screed is a gypsum sheets. This material is much stronger than drywall. The connection happens between the sheets with folded edges, which are glued with special adhesive mass and is secured with screws.
We must start from the front door. In order not to damage the smooth surface, consisting of clay and sand, should be installed on top of the first sheet to overlay another, which can become to continue. All the joints of the plates of the scroll screws.
