If water leakage occurs, consumers firstly clean up the construction surface, completely remove loose materials and oil stains, and paint as much as possible. If there is obvious lack of surface strength, it should be reinforced first, and then surface waterproof coating. Wet the construction surface and reach as much internal dryness as possible.
