Cement based permeable crystalline waterproof coating
Cement-based infiltration crystalline waterproof coating is a powdery rigid waterproof material made of special cement, quartz sand, etc., mixed with various active chemicals. When used, add water to prepare a slurry, paint on the cement concrete structure base surface, and form a rigid adhesion coating on the surface of the concrete structure after curing. The active chemical substances contained in the coating penetrate the concrete through the water carrier and catalyze the concrete. Silicate produces water-insoluble crystals, filling and plugging capillary pores and fine fissures. It is suitable for permanent impervious and waterproof engineering of concrete structures such as basement concrete structures, tunnels, sewage treatment tanks, tap pools, sewers, elevator shafts, and swimming pools.
