Polyurethane waterproof coating waterproof layer is too thin: polyurethane waterproof layer must reach a certain thickness have waterproof effect, polyurethane waterproof coating, the polyurethane material itself is still relatively low water absorption characteristics, if insufficient water layer thickness, two-component polyurethane waterproof coating, After days of heavy rain, the rain through the polyurethane waterproof layer to the bottom, through good weather sunshine, K11 waterproof coating, still produce steam at the bottom, causing the waterproof layer peeling. Best adhesive fiberglass mesh in all the corner is reinforced, polyurethane waterproof layer to prevent rupture resulting in leakage. Choose waterproof coating four principles should be considered: (1) the extent of ground deformation, structure, local annual temperature, daily temperature and vibration factors, should choose to adapt the tensile properties of waterproof coating. (2) According to the degree of exposure of roofing coating, Hebei waterproof paint, you should select UV resistant, heat aging retention adapt waterproof coating. (3) According to the calendar of local maximum temperature, minimum temperature, roof slope and conditions of use and other factors, you should choose the heat resistance and low temperature flexibility to adapt to the waterproof coating. So as to prevent the flow or cold crisp. (4) Roof drainage slope is greater than 25%, should not be used too long dry film component polyurethane waterproof coating waterproof coating | long source (Online) | Wuhan waterproof coating provided by the Weifang City waterproof material Co., long the source. 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.
