<p>Waterproof indoor commonly used four types of waterproof mortar coating what? Currently on the market, if we according to different properties, Chongqing Institute of Polar waterproof material developed four commonly used indoor waterproof coating: such as "polymer waterproof mortar (dry powder and waterproofing agent)", "two-component polymer waterproof coating "," One-component polyurethane waterproof coating "," acrylate waterproof coating "because of their different properties, each has its advantages and disadvantages, and the corresponding treatment. Acrylate 1. Rigid waterproof mortar: also known as rigid waterproof mortar. polymer dry mortar, add water directly brushing or Tucao two can be waterproof. </p><p> emulsion and mortar ratio of 1: 4, after brushing without the need for coating treatment, the thickness of 2mm or more. waterproofing agent and a certain proportion of cement sand to do leveling layer thickness of 20mm or more. The construction of these three materials is not rigorous. Good construction on damp ground level, no need to do leveling layer and protective layer can be directly affixed to brick, more convenient to form cement block after curing, will not package seepage water, the waterproof effect of the back surface is good, the price is relatively low Its biggest advantage.</p><p> The disadvantage is that such mortar higher hardness, which is more suitable for the bathroom waterproof, pay attention to the construction of the water around the mouth and must be flexible waterproof coating to strengthen treatment. Gray paddle with flexibility, even if the deformation of the grass-roots deformation will not affect the waterproofing effect. Used for walls and floors and other water-facing, not for the top and other backwater, if the water is not good, water infiltration, it is easy to package seepage. Flexible mortar there is a class of silicone waterproof coating, which belongs to the high-grade flexible mortar, elastic tension and flexibility are good.</p>
