That is after the cement is dry, the moisture in the cement in the wall tiles evaporates to form a void, so you have to be careful when you want to punch holes in the tiles, and the tiles will crack if you don't get them right.
Sit back and wait for the tiles to fall off and repair them partially, or remove them all and re-paste them. Generally, the brick is empty, you don't let him work the surface, there is no problem.
You can spray it with the kind of detergent used for the kitchen and then brush it with a steel wool ball or a small brush, if it doesn't work, you can try 84 disinfectant.
Look at how big the crack is, if it's small, you don't need to dismantle it, if you don't think it's beautiful enough, you can replace it.
After the tile of the kitchen and bathroom wall is pasted, there is an outward curved stool situation, because the problem of tiles is not a problem of construction, because if the tile is of good quality, there will be no outward curved type after the construction.
