In the bathroom, the wall of the bedroom is waterproof and redone, and the polyurethane waterproof can be brushed twice.

If you have determined that the wall is damp and moldy because the waterproofing layer is not done well, then only the surface of the mold removal will have no substantial effect. Because of the problem with the waterproof layer, the bathroom still needs to use water for a long time in the future, even if the mold is removed now, it will still be because of the water leakage for a long time, so the problem cannot be fundamentally solved.
In this case, it can only be partially or completely re-waterproofed with kitchen and bathroom waterproofing slurry according to the actual situation, so as to fundamentally solve the problem.

Painting on the outside doesn't do anything! The key is that the indoor waterproofing is not done well, it is recommended to remove the tiles and redo the waterproofing, and solve it completely!
The surface of the bathroom must be chiseled off with a decorative layer such as a face brick, and after the base surface is leveled, the JS coating film waterproof layer must be painted, and then the paving of the face bricks must be restored.
