Polyurethane waterproof coating characteristics: (1) can be applied directly to wet or dry surfaces of various substrates. (2) strong bond with the substrate surface, the coating of polymer material can penetrate into the base fine slit, follow-strong. High bond strength, apply waterproof materials and concrete, wood, ceramics, etc. have a strong adhesive force can also be applied to part of the polymer membrane bonding; (3) coating has good flexibility, the grass-roots stretching or cracking strong adaptability and high tensile strength. (4) environmental protection, non-toxic, tasteless, non-polluting environment, no personal injury. This product is canceled coal tar waterproof coating, greatly reduce the pollution of the environment. Waterproof coating construction process: 1, the liquid additive into a clean mixing container color polyurethane waterproof coating, then proportionally added slowly while stirring the powder, stir 3-5 minutes until the dough generate free, homogeneous plastic pulp, and used within the operation time. It recommends the use of mechanical agitation (400-500 rev / min) 951 polyurethane waterproof coating for best mixing effect; 2, with a roller, brush evenly brushing the slurry on the substrate in the processing good, depending on the environment and performance Requirements brushing 2 or two layers above; general engineering waterproof layer thickness of 1mm, underground construction norms required thickness of 1.5-2mm; 3, after finishing one must wait until slightly dry solids (just tack) after polymer cement-based waterproof coating, then a second layer, which normally takes 1-3 hours, depending on the density of the base surface and then the temperature may be. If more than 24 hours, or the coating has been cured, brushing second layer thereon, must be re-wet the surface with water. Two-component polyurethane waterproof coating _ long the source of waterproof material (certified) _ waterproof coating Shandong Weifang City for the source provided by waterproof material Limited.
