How to do bathroom waterproofing, does anyone know?

You don't know if the bathroom you are talking about is a household bathroom or a public bathroom decoration like the office, so I will focus on the bathroom decoration at home

There are three areas of waterproofing in the bathroom that require great attention: the floor, the wall, the joints between the walls and the floor, and the joints between the water and water pipes and the ground.

Floor: The bathroom floor is waterproof and smoothed first. In order to avoid leakage caused by uneven thickness of waterproof coating.

Wall: In the general bathroom waterproofing treatment, the wall should also be made about 30 cm high waterproof paint to prevent water from penetrating the wall. But if it is a shower, the wall should be made meters high; In the case of a bathtub, the height of the waterproof coating on the wall adjacent to the bathtub should also be 30 cm higher than the upper edge of the bathtub.

Joints and corners: The joints between the bathroom wall and the floor, the joints between the water and sewage pipes and the ground, and the door threshold are the most likely places to cause problems. In the construction, we must urge the workers to deal with these corners and corners, and all waterproof coatings must be applied "in place".

After the construction is completed, the waterproof craftsman will provide a warranty card promising a ten-year warranty for repairs at a time.
