    Bathroom waterproofing is required to be 180cm high, and the wall waterproofing is to prevent water from penetrating through the wall to the other side, resulting in putty and paint pulverization, bulging, and falling off. After waterproofing, add an appropriate amount of sand with cement, mix it with water and building interface agent glue evenly, and sprinkle the adjusted cement mortar evenly on the surface layer of the waterproof layer with a broom.

    Of course, it should be redone, so that the effect will be good, and the use time will be longer.
