Design documents provide for a specific choice of waterproofing material is a very important job. For example: When the roof with bitumen membrane waterproofing layer, the surface layer should be required to lay asphalt waterproofing membrane No. 500 (piece felt) polyurethane waterproof coating, to serve as a protective layer; waterproofing membrane used for all kinds of binder, adhesive, should indicate the species, size, thickness or the amount of which bitumen membrane waterproof layer of asphalt Mary really should use fat binder type polyurethane waterproof coating not use pure asphalt; should be combined with the engineering characteristics of polyurethane waterproof coating wholesale, waterproof construction details seriously, the additional layer structure node using the site, the enhancement layer materials, seam sealing materials, and various fittings shall be marked varieties, specifications polyurethane waterproof paint brand, an important part of the bulk sample should be made detailing and operational requirements of the specification . Features 1, slurry cement-based active ingredients can penetrate the surface of the micro-cracks crystalline form a dense waterproof layer. To cover small cracks, against a slight concussion; 2, construction in the wet base surface, without making a protective layer of mortar, tile, etc. can be directly attached to the follow-up process; 3, crystalline material deep in the end pores, permeability than the compressive strength high, with a positive side and a back surface of the waterproof function; 4, non-toxic, harmless, can be directly used for drinking water pool and fish pond; 5, the coating has a depressive effect of mold growth, can prevent moisture contamination of salt finishes .
