1. Do a leveling. First, use cement mortar to level the floor (especially the house that has been refurbished) and then do waterproofing. This can prevent the waterproof coating from leaking due to uneven thickness or piercing the waterproof membrane.

2, to do a good job. The seam between the wall and the ground and the joint between the upper and lower water pipes and the ground are the most prone to problems. Therefore, these parts must be paid special attention, the treatment must be meticulous, and there must be no sloppy.

3, the wall must also be waterproof. In order to achieve a better waterproof effect, the wall surface of the general bathroom should also be waterproofed to a height of about 30 cm to prevent water from escaping through the wall. The wall adjacent to the bathtub is also water-treated to a height higher than the upper edge of the bathtub, and the shower must be 180 cm high.

4, to do waterproof experiments. After the waterproof construction is completed, all the sewers in the toilet should be blocked and the water injection test should be carried out. Check after 24 hours, if there is no leakage around the wall and floor of the bathroom, the waterproof quality of the bathroom is very good. On the contrary, find out the missing points and carry out maintenance.
