    The main cause of the problem is caused by improper construction. Specifically, there are the following questions:

    1. The wall surface of the tile is not brushed when it is paved.

    2. Judging from the figure, the selected ceramic tile is ceramic brick, commonly known as porcelain tiles, which can not be paved with pure cement mortar in the process of paving, and needs to be paved with cement sand according to the volume ratio of 1:3 configuration. The ceramic brick is paved with pure cement slurry, the strength of the cement slurry is too high, the expansion coefficient is large, and the tile on the surface is easy to squeeze or fall off in the later stage.

    3. When the cement mortar is used to pave the tiles, the wall is not sprinkled with water, which causes the dry wall to absorb the moisture in the cement mortar too quickly, resulting in the formation of hollow drum delamination between the cement mortar adhesive layer and the base layer, which leads to the cracking and falling off of the tiles in the later stage.

    4. The seam in the process of tile paving is too narrow, and when it is used in the later stage, the ceramic tile and the cement mortar that bonds the tile will cause the tile to crack when it is hygroscopic or heated and expanded.

    Repair suggestion: The best way is to dismantle the entire bathroom and renovate it. This includes the installation of waterproofing and tiling and bathroom fixtures. If you just want to solve it temporarily, it is recommended to conduct a thorough construction quality inspection of the entire bathroom tile paving condition, and there is a place where the tile paving is hollow and delaminate in the area where there is no cracking and falling off, and then remove the loose base layer, and then do waterproof and brushing treatment on the surface, and then use cement mortar to paste new tiles.
