Heat-insulated floor C-40 cement-based foam for leveling and warming floor. APPLICATION AREA The mixture C-40 is designed for thermal insulation, insulation and noise insulation of the floor in places of all grades for the preparation of bases for self-leveling solutions up to 10 cm thick(up to grade 200). The mixture can be used for such coatings as linoleum, carpet, laminate, parquet, ceramic tile, natural stone, etc. COMPOSITION The mixture C-40 is made on the basis of polystyrene, high-quality Portland cement, mineral aggregates, functional additives of leading European manufacturers. TECHNICAL DATA The proportion of the mixture is 0.08-0.1 L of water / kg. Open work time - no more than 30 minutes. Adhesion to concrete - at least 1.5 MPa. The temperature of the substrate is from + 50 ° C to + 300 ° C. The operating temperature ranges from -500C to + 700C. PREPARATION OF FOUNDATION The substrate must be strong enough and even, cleaned of dust, dirt, lime, fats or oil chamfers. Fragile areas of the base must be removed. Gypsum, as well as highly absorbent base (plaster, cellular concrete, slag blocks, etc.), must be treated with a deep penetrating primer emulsion. Considerable unevenness of the substrate must be filled with a starting plaster mortar. PREPARATION OF THE SOLUTION Dry mixture C-40 must be filled up in water at the rate of 0,08-0,1 l of water per 1 kg of the mixture with simultaneous mixing by hand or mechanically until a homogeneous and elastic mass is obtained. After 5 minutes, the mixture must be re-mixed, after which it can be used for 30 minutes at most. MODE OF APPLICATION The prepared C-40 solution is spread over the surface of the prepared substrate using a rubber measuring strip and other tools. The thickness of the disposable layer is up to 10 cm. CONSUMPTION The consumption of the mixture with a layer thickness of 1 cm is 5-7 kg / m2. NOTE Work should be performed at a temperature of + 50C to -300C. All the above recommendations are effective at a temperature of +20 ° C and a relative humidity of 60%. In other conditions, the setting and setting time may change. STORAGE In a dry place in branded bags. The warranty period of storage is 12 months from the production date.
