The bathroom wall will fall off after being brushed with waterproof, what method to solve

To do waterproofing, you need to do it on the surface of the water and dig it.

Excellent permeable crystalline waterproof, can be do-it-yourself.

If the cement surface is waterproofed, use a super permeable waterproof guard to do waterproofing (if there are cracks, gaps and potholes on the cement surface, fill the complete with Meiding porcelain glue and then do waterproofing).

For the tile surface, first check whether the filling of the tile gap is complete (if the filling of the tile gap is incomplete, fill it with Meiding porcelain glue, and then use a stone tile waterproof guard to do waterproofing).

Exterior wall paint can be made waterproof with transparent waterproof repair adhesive.

The product will penetrate into the base layer and make the base layer waterproof. The product is recommended to be constructed in a dry place, the drier the base surface, the deeper the product can penetrate, if the base surface is full of moisture, high density, the material can not penetrate well. Regarding the principle of waterproof plugging, the source of water leakage is not blocked, and the water will only continue to penetrate into the wall, which will exist inside the wall for a long time, and will leak out from other parts of the wall when the water reaches a certain level.

The problem cannot be solved, and only by spraying waterproofing agent on the outside of the roof or exterior wall so that the water cannot penetrate into the wall and flow away can the problem be completely solved.

Gluing tiles with tile mastic will not fall off.

Re-paint the cement and then put on the tiles.
