Therefore, there will be no leakage without destroying the original waterproof layer. However, the common problem now is that some toilet facilities and various water supply and drainage pipes will be rearranged or moved into decoration, destroying the original waterproof layer. If it is not repaired or redone, the problem will be discovered only after the leakage occurs, and it is difficult to repair at this time.

Generally speaking, the waterproof wall must be 30 cm high, but the lightweight wall without load must be watertight, at least 1.8 m high.

Experience: The wall near the shower room should be 1.8m high. If a bathtub is used, the height of waterproof paint on the wall near the bathtub must be higher than the upper edge of the bathtub.

The fourth step of waterproof bathroom in Changzhou is to repair floor tiles to make the ground waterproof.
