Is the bathroom waterproof polypropylene membrane or waterproof coating?

Waterproof coating is better. If the pipe is irregular when using the membrane, it will increase the difficulty of the construction of the tarpaulin, and the tarpaulin will not have adhesive force, and it is easy to produce seepage and leakage in the humid environment of the bathroom. It not only reduces its waterproof effect, but also affects the aesthetics of the entire waterproof layer of the bathroom, if you use waterproof coating, the operation is simple and convenient, and the waterproof is very good.

Not good, the area is too small, there are more drains, and the treatment is not dry.

It is not recommended to use polypropylene membrane for waterproofing in the bathroom, because the bathroom is a relatively stable part of the house structure, so the waterproof requirements will be lower than that of the balcony and roof.

It is recommended to use waterproof coatings, and the use of polypropylene lap edges is prone to leakage. Waterproof process: base treatment, cleaning, leveling layer, bonding layer, detail additional layer, acrylic waterproof layer, water storage test, protective layer construction, secondary water storage test. >>>More
