Whether in construction, or again some industrial production, a lot of time must be used to waterproof technology; such as waterproof concrete in construction. So people have developed a variety of waterproof material, which can be divided into two categories color polyurethane waterproof coating, are waterproof membrane and waterproof coatings. This is now the mainstream market, waterproof material, which is one of the waterproof coating polyurethane waterproof coating mainstream; compared to the waterproofing membrane, a waterproof coating usage more simple and convenient, while transport can be stored for relatively much simpler. Then the polyurethane waterproof coating construction process, which needs to pay attention to the problem? (1) the construction of temperature, which is a very important point, because the temperature has a great influence on the performance of waterproof coating; the best construction temperature should be between 5-35 degrees. (2) When using polyurethane waterproof coating, formulated coating preferably within one hour of running out of polyurethane waterproof coating ingredients, otherwise the rest of the coating performance can not be guaranteed. (3) polyurethane waterproof coating is a finished coating, it does not need to add any of the ingredients and water use. Basement wall leak: The reason without making waterproof or waterproof basement did not do. There are tiny pores inside is not dense form seepage channel, groundwater under pressure into the channel, causing the wall leakage. Maintenance: The lower the water table, try to operate under anhydrous state, the first leak scrub clean the walls, remove the fill level at hollowing, wall cutting hair with a waterproof material quickly stanch smear the walls, to be solidified polyurethane waterproof paint manufacturers, with a suitable waterproof paint or new waterproof materials and then brushing again. According wall leaks, using a variety of methods governing leakage, such as ferric chloride waterproof mortar surface treatment. M1500 spraying cement sealant. Cyanide coagulant treatment method. Two-component polyurethane waterproof coating, waterproof polyurethane coating Tianjin, long a source of waterproof material provided by the Weifang City for the source of waterproof material Limited. Weifang City for the source of waterproof material Ltd. (www.jiuyuanfangshui.com) strong, credible, Shandong Weifang waterproof, moisture-proof materials industry has accumulated a large number of loyal customers.
