1, two-component polyurethane waterproof coating construction procedures and methods 1) Basic process a). Substrate should be solid, wood investment agents smooth surface, no blisters, voids, and should be clean and dry. If blisters, voids, should wipe cement mortar, it requires the use of smooth calendering or incorporated into the cement content of 10% -20% polymer emulsion modulation putty filling gelling. b). In case of sanitary ware, wall bushing, etc., shall be required to install a solid polyurethane waterproof coating environmental protection, tighten smooth. 2) coating the primer to the primary surface dust and debris cleaned up after, and then the two-component polyurethane coating by Group A: B Score: thinner = 1: (1.5-2.0): 2.0 ratio (mass ratio, the same below), or required by the product specification Stir after mating, and then long to roll brush dipped in the mixed material, even brushing the cleaned surface of base can not accumulate when brushing or grin bottomed waterproof polyurethane paint walls, painted amount of 0.2kg / m2 or so. After brushing should be dried and cured more than 4h before proceeding to the next step of construction. [Features] 1, never cured, cured content of greater than 99.9%, almost no volatile matter, always keep the original state after construction jelly. 2, durability, fatigue resistance, high temperature resistance, excellent extensibility, non-toxic, tasteless, non-polluting, non-flammable on fire. 3, good adhesion, and any foreign bondable, and can be applied over damp base surface after bonding can effectively prevent the phenomenon of channeling water. 4, good flexibility, suitable for grassroots deformation, no peeling. 5, self-healing and strong, even if the construction waterproof coating damage can repair itself, maintaining the integrity of the waterproof performance. 6, construction methods and diverse, scraping construction of one-component polyurethane waterproof coating color can spray, cold construction, winter can be construction. 7, can be used in conjunction with other waterproof material to form a composite waterproof layer, improve waterproof effect. 8, the construction material will not be separated, can form a stable, seamless whole waterproof layer, easy maintenance and management.
