Waterproof and leakage repair of Shenzhen bathroom
Time:2020.08.04
Due to the structure and use of toilet, the complexity and importance of toilet waterproof and leak repair are determined. How to do a good job in toilet waterproof and leak repair is an extremely concerned problem.



The toilet is usually waterproof: the toilet area of ordinary residence is narrow, and there are pipelines passing through the floor, so the coating is commonly used for waterproofing, but coiled material is rarely used. There are two kinds of waterproof coating: synthetic polymer polyurethane waterproof coating (need to add polyester cloth, glass fiber cloth, etc.) polymer modified asphalt -- SBS waterproof coating (need to add matrix reinforcement material polyester cloth, glass fiber cloth, etc.) asphalt based waterproof coating is basically not used. The general practice of polyurethane waterproof coating is as follows:



1: The ground should be sloped towards the floor drain, cement mortar or pea stone concrete can be used, but the surface should be flat. The slope near the door is small, and the slope near the floor drain is large, which should be mastered according to the specific situation.



2: The pipeline passes through the root of the floor, and the waterproof is strengthened. After the pipe root is sealed with building sealant, the cement is troweled, and the waterproof coating is applied, 1 ~ 2 layers of glass fiber cloth strengthening layer are pasted. The same measures should be taken near the floor drain.



3: The wall surface shall be clean and smooth without floating ash and small particles, and the joint of wall and ground shall be plastered with small original angle or slope angle. Apply 1-2 layers of glass fiber cloth strengthening layer when applying waterproof coating.



4: The total thickness of polyurethane waterproof film should be more than 1.5mm. It can't be decided by the number of passes. The reinforcing layer of pipe root and wall corner shall be brushed first, and then it shall be surface dried for 4H at room temperature, and then large-scale painting and scraping shall be carried out. No missing scraping and blistering are allowed. Large area brush for 24 hours, then brush the next layer after curing.
