Just renovated, adjacent to the wall of the bathroom, the baseboard position is damp, and the wall i

If there is no water seepage caused by water pipes, then it is very likely that the waterproofing done by your bathroom has been damaged, and this is the water seepage into the wall when the bathroom is water, which leads to the water seepage and mold of the wall in your photo, and the water seepage in the bathroom needs to be treated, and then the wall is treatedIn order to achieve a better waterproof effect, you can also buy a water armor to paint the tile surface, this kind of paint is a permeable coating, penetrating into the inside of the tile to achieve the waterproof effect, so that the lower tiles can also achieve the waterproof effect, I hope my answer can be helpful to you.

Does this need to be asked? Of course, the bathroom floor is not waterproofed, and the waterproofing agent is generally not added when making the base cement.

Or the waterproofing is too low, only the floor is made, and the surrounding walls should also be waterproof at least 80 cm.

Although there is no water to be seen, the water can be soaked along the walls by the capillary siphon of the cement.

There is also a type: if there is a water pipe in the wall, it may also be that the water pipe is seeping, and the water flows along the wall to the floor because it is waterproof, and seeps out from the baseboard height.

The reason for this problem is the waterproofing of the bathroom, that is, the waterproof coating film at the junction of the wall and the floor is not seamless.

In the case of no shower in the bathroom, the problem of water seepage is likely to be caused by leakage at the buried water pipe joint in the bathroom. It is recommended that the water pipes be checked for a pressure test.
