Defects and seepage must be carefully treated surface of the substrate before coating waterproof coating. Because the coating has not yet solidified, such as by the action of water pressure will not be solidified coating or the formation of voids, polymer cement-based waterproof coating, the formation of water leakage problems. Base surface clean, no floating pulp, help paint a uniform coating, and with the base surface has a certain cohesion. The base surface dry hard to do in underground engineering, so this provision only made no drops, no water seepage requirements. When carrying out the construction of waterproof paint, we go in order to better ensure the wall waterproof layer has a better smear quality during construction can save more waterproof paint, paint the five elements to avoid waste, Xiangtan waterproof coating must be on the wall of the grassroots, inside and outside over the wall and the end wall of the inside edge smoothing treatment, one-component polyurethane waterproof coating, see uneven phenomenon promptly be removed, if equipped with Honeycomb, wall floating ballast , floating dust and oil, it should be avoided. 951 polyurethane waterproof coating | waterproof long source material (certified) | Xiangtan waterproof coating provided by the Weifang City waterproof material Co., long the source.
