Waterproof coating characteristics: (1) waterproof coating prior to curing and viscous liquid, therefore, the construction not only in the horizontal plane waterborne polyurethane waterproof coating, but also in the facade, Yang angle and a variety of complex surfaces waterproof coating to form a non-contact complete waterproofing membrane joints; (2) when used without heating, reducing environmental pollution, but also easy to operate and improve working conditions; waterproof layer (3) formed small weight, especially for light roof waterproof. (4) waterproof membrane forming a greater extensibility, water resistance and weather resistance bridge with a waterproof coating, can adapt to small changes in the grassroots cracks. (5) The host material coated waterproof coating, is both waterproof layer, but also the adhesive, it is easy to bond quality assurance and maintenance is relatively simple. Especially the implementation of the base crack, construction joints, water bucket and runs through some of the sites likely to cause leakage around the tube, etc., can easily be enhanced brushing, patch and other operations. Waterproof coating construction process: 1, the liquid additive into a clean mixing container, then proportionally added slowly while stirring the powder, stir 3-5 minutes until the dough generate free, homogeneous mortar, and in operating time has run out. It recommends the use of mechanical agitation (400-500 rev / min), in order to obtain the best mixing effect; 2, with a roller, brush evenly brushing the slurry on the substrate in the processing good, according to the environment and performance requirements for brushing 2 layer or two or more layers; general engineering waterproof layer thickness of 1mm color polyurethane waterproof coating, underground construction norms required thickness of 1.5-2mm; 3, after finishing one must wait until slightly dry solids (just tack) after , 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. Bridge with a waterproof coating, long the source of (certified), Liaoning waterproof coating provided by the Weifang City for the source of waterproof material Limited. Weifang City for the source of waterproof material Ltd. (www.jiuyuanfangshui.com) Shandong Weifang, waterproof, moisture-proof material leader, over the years, the company is implementing the scientific management, innovation and development, the principle of honesty and trustworthiness, and satisfy customer needs. In the long waterproof material source leadership with the staff warmly welcome all inquiries negotiations to create a source of long waterproof material better future.
