Coating polyurethane waterproof coating is mainly applied to the bathroom, roof or basement waterproofing all fittings, sanitary equipment, floor drain or drains, etc. must be securely installed, waterproof coatings, tight joints, closed head smooth, without any loosening. Shovel and broom with tools such as the primary surface asperities, mortar pimple eradication, polyurethane waterproof coating, dust debris will be cleaned thoroughly. On the angle, pipe roots, floor drain and drain and other parts should carefully cleaning. If found oil, rust use wire brushes, sandpaper and an organic solvent cleaned. The moisture content of less than 9%, PH value <10 primer coating. Waterproof cement-based powder coating is generally waterproof coating with hydraulic properties, as the main bonding material is cement, under which the role of catalyst deposition, hydrophobic component, in two-component polyurethane waterproof coating, and cement Together, dense structure together form a thin film on the substrate surface, a polymer cement-based waterproof coating, closed surface cracks, pores, thus clogging the passage of water; and hydrophobic properties of waterproof coating itself has, can greatly improve newborn surface Surface tension, reduce water wetting ability, thereby enhancing the water repellency treated surface.
