Toilet waterproof precautions:


1, waterproof treatment

Do the ground waterproof layer first, the coating should be uniform, thickness ≥ 1.5mm. Pay attention to the dead angle during construction, between the wall and the ground, between the water pipe and the ground. The walls shall be waterproof and refer to the ground. The waterproof layer on the side walls shall be ≥20cm high. There shall be bathtubs. The waterproof layer shall cover all parts where the shower can be sprayed. Of course, four walls of waterproof can also be done at the top of the wall, and the roof of the bathroom can be made waterproof better.

2, waterproof inspection

After the waterproof construction is completed, all sewers of the toilet shall be blocked, and a “low wall” shall be built at the entrance of the bathroom for water injection test. The height of water injection shall be about 10cm. After 24 hours inspection, if there is no leakage around the bathroom wall and the ground, the waterproof quality of the bathroom is very good. Instead, find the leak and perform maintenance.

3, tile paste

After the water-retaining test is completed, let it dry for 5-7 days. Add a layer of cement mortar on the waterproof coating. After the protective layer of cement mortar is dry, it can be tiled. The floor should have sufficient inclination to the floor drain to facilitate drainage. The tiles on the floor should be non-slip, waterproof, and the wall tiles should not absorb water, otherwise there is a color difference.

The above is about the reasons for leaking water in the bathroom and the introduction of waterproof precautions. I hope to be helpful to everyone.
