Polyurethane waterproof coating is a diisocyanate, polyether formed by the addition polymerization of isocyanate group-containing prepolymer, together with the catalyst, anhydrous additive, anhydrous fillers, solvents, etc., is made by mixing such as processing The single-component polyurethane coatings. Class coating reaction curing type (moisture-curing) coatings with high strength, elongation, good water resistance characteristics. Adaptable to the grassroots deformation. Polyurethane waterproof coating is a liquid one-component construction of environmentally friendly waterproof coating, is no tar and asphalt additives imported polyurethane prepolymer as the basic ingredients. It is contact with moisture in the air after curing, the primary surface layer of solid tough seamless overall anti-film. Roofing construction: waterproof grass requires a solid firm, can not afford to sand, no Honeycomb, substantially dry, must remove floating dust; old roofing must clear the original waterproof layer aging damage, damage to the grass-roots requirements repaired with cement. Before the large-scale construction must be diluted with water base paint after the above polyurethane waterproof coating usage, to enhance its adhesion with the grassroots; dilution ratio: waterproof paint: water = 1: 2-3; seam roofing binned first oil paste caulking, waterproofing material plus non-woven fiberglass cloth reinforcement layer 951 polyurethane waterproof coating, reinforcing layer requires between 20 and 30 centimeters in width. Then carefully processed first waterproof layer within the range of detail, such as out of the water hole, extending roof side piping, structural stress concentration construction site, the more hidden corners and other parts of spacious and easier to produce other leaking parts, and according to conventional a large area of ??brush. Sixth, the coating method: Brushing first waterproof coating slightly above it down evenly stirring, brushing method: Available spraying, brushing, knife coating, roll spreadability can; if too thick waterproof coating is not easy to construction, available diluted with water so that it is appropriate to facilitate coating.
