Screed Floor Laying ties begins with the preparation of the base. If a future screed will be a smooth concrete floor with a smooth cement surface, then for a firm grip on ties with the foundation must first be roughening of the surface roughness of mechanically or with concrete contact. Previously it is important to close all the gaps between walls and slabs of cement-sand mortar or putty, to remove grease and oil stains, remnants other materials, dust-free. You must then apply the primer deep penetration that will not only ensure better adhesion, but also to prevent water penetration into the ground. After that will be seal the walls and bottom of the walls to prevent moisture penetration, the upper edge of the insulation should be 15 cm above the level .V depending on the type of floor covering and the required quality surface for laying ties may include the following materials: screeds, dry mixes for self-leveling floors, cellular, lightweight concrete, cement-sand mortar. The choice of material also depends on the thickness of the future Ties and duration of exposure before being packed cover. Duration of hardening ties depends on its thickness, from which it is made and the type of flooring. Thus, the cement-sand mortar harden in 28 days. Pouring and leveling compounds contain various polymer additives, which influence the solidification, so the process can take anywhere from 24 hours up to a month. Ties depends on the thickness of what it is placed, what material holds a floor covering will then be selected. In any case, the minimum thickness of screed is 5 cm in this case it strengthens fittings or metal mesh. For the immediate strengthening ties apply different types of impregnations and ground depending on the purpose of sex and grade of concrete used in the material for...
