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
The area of the bathroom is relatively small, there are many pipes, if the polypropylene membrane is used, it is not easy to cut and paste, and there will be a pungent smell, which is not very environmentally friendly indoors. The cement-based coating is a waterproof material that has both high elasticity of synthetic polymer materials and good durability of inorganic materials. Environmental protection is good, there is no pungent smell, waterproof cement-based coating is relatively simple, and it also has good flexibility, so the cement-based coating for waterproofing in the bathroom is better.
There is no impact.
Remember to do waterproofing before tiling, and do it two or three times on all four facades and floors of the room. It is useless to do waterproofing after pasting tiles, you must do waterproofing before pasting tiles, otherwise it will leak after a long time. >>>More
You ask the group about this, I don't understand what you mean.
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.
