Anonymous users2024-01-24Bathroom waterproof specification 1:
Make sure the floor of the restroom is stable. If you need to replace the floor tiles in the bathroom, after chiseling off the original floor tiles, be sure to level the floor with cement mortar first, and then do waterproofing treatment. This avoids leakage of the waterproofing coating due to uneven thickness.
Bathroom waterproof specification two:
The seams should be painted in place. The joints between the walls and floors of the bathroom and the joints between the water and water pipes and the floor are the most problematic areas.
Toilet waterproofing specification three:
Wall treatment is also important. In the general toilet waterproofing treatment, the wall should also be made about 30 cm high waterproof paint to prevent water from penetrating the wall. However, if the wall of the bathroom is a non-load-bearing lightweight wall, the entire wall should be coated with waterproof paint.
Bathroom waterproof specification four:
The waterproof experiment must be done. After the construction of the toilet is completed, all the sewer in the toilet is blocked, and a 25 cm high "barrier" is built at the door, and then 20 cm high water is poured into the bathroom.
Bathroom waterproofing specification five:
Keep the sewer pipes clear. All sewer pipes in the bathroom, including floor drains, plumbing pipes for sanitary ware, etc., should be kept unobstructed.
