Floor screed reinforced PSP-031 – ready-made dry mixture reinforced with polyamide fiber for screeds, screeds at an angle, leveling and repair of strong bases resistant to deformation (cement, concrete, expanded clay and others) before applying leveling mixtures, laying tiles, parquet, laminate or other decorative coatings. It is used inside dry or wet rooms and outside buildings. Gives an even, smooth, strong horizontal surface. Due to the high fiber content and optimal granulometric composition, it has high strength and increased crack resistance, so it can be used in various structural schemes (floating floors, heated floors, etc.). It is applied in a layer thickness from 10 to 100 mm. If there is a need to increase the elasticity, hydrophobic properties or adhesion of the solution to the base, prepare the solution mixture using concentrated emulsions TM POLYPLAST: contact PL-125, elastic PL-127.
