Introduction cementitious capillary crystalline (3) cementitious capillary crystalline waterproofing materials are made of Portland cement, quartz sand, specialty chemicals and other components of the active waterproof material. Polyurethane waterproof coating samples under the guidance of the water, with water as the carrier, with a strong penetration of polyurethane waterproof coating price transmission in the concrete pores and capillaries, filling, physical and chemical reactions take place to form a water-insoluble dendrite-like crystals , and the crystal structure was integrated into the concrete waterproofing layer integrally closed to intercept the water flow from any direction and other directions and other liquids erosion. Polyurethane waterproof coating construction process: 1. sweeping grassroots polyurethane waterproof coating, brushing primer 2, 3 detail additional layer, the first layer of the coating 4, 5 second layer coating, six third layer coating.... Gravel and sticky film. Cleaning the grassroots: The blade will stick to the leveling layer of skin to get rid of gray, with a broom sweeping clean the dust polyurethane waterproof coating manufacturers, especially root canal, drain and drain and other parts should be carefully cleaned. If any oil, use a wire brush and brush or sandpaper to intermediaries in oil paint and mortar surface brushing together. The surface must be flat, depression 1:3 use cement mortar. Polyurethane waterproof coating wholesale, long a source of waterproof material, polyurethane waterproof coating provides long-source by Weifang waterproof material Limited.
