How to stick tiles without destroying the waterproof layer and prevent tiles from falling off after the cement wall is waterproof?

Reason: Don't be confused at first when you encounter the situation that the brick is not firm after the wall is waterproof. Finding out the reason is your important job before. In fact, the main reason is that when the tiles are pasted, the back of the tiles will be coated with cement mortar, and the water will solidify after infiltrating into the wall. But with the waterproof layer, the wall will become very smooth, which will prevent water from entering, and it is not easy to dry, so it is not easy to fix when sticking tiles.

solution

A, waterproof coating should be used in strict proportion, or after the waterproof is dry, use cement to "nap" the wall and then stick bricks;

B, if you use cement mortar, don't put it too thick, and leave some gaps between tiles. If you use tile glue, you don't need to consider these details.

Waterproofing agents can be divided into rigid and flexible, and flexible waterproofing agents are more elastic and have longer service life. However, when the tile is attached with flexible waterproof agent, the tile will be slightly deformed during drying and pull the waterproof layer. This will cause the tile and waterproof layer to fall off together.

Rigid waterproofing agent has poor elasticity, but correspondingly, it has higher adhesion to the wall. Pulling tiles will not only tear off the waterproof layer, but also pull tiles to prevent them from falling off.

Waterproofing agents commonly used in families generally do not directly refer to rigidity and flexibility, but have more subdivided names-for example, rigid waterproofing agents used on walls are called "cement-based permeable waterproofing agents".
