2. The pipeline passes through the root of the floor to strengthen waterproofing. After the building sealant at the pipe root is sealed, cement shall be applied to smooth the feet, and glass fiber cloth reinforcement layer 1~2 shall be applied when waterproof coating is applied. The same measures are taken near the floor drain.
3. The wall should be clean and smooth, free of floating ash and small particles, and the junction between the wall and the ground should be painted into the original angle or slope angle. Stick glass fiber cloth reinforcement layer 1~2 when brushing waterproof paint.
4. The total thickness of polyurethane waterproof coating should be greater than 65438 0.5 mm. It cannot be determined by the number of passes. Brush the pipe root and corner strengthening layer first, and then brush and scrape it in a large area after drying at room temperature for 4 hours. There should be no leakage, scratching or blistering. Brush a large area for 24 hours, and then brush the next layer after curing. Brush the elevation first and then the plane, and the next brush direction is perpendicular to the previous one. When the film is semi-cured for the last time, the coarse sand particles are dragged to facilitate the combination with cement mortar in the future.
5. The waterproof layer on the ground outside the bathroom door should be brushed 300 wide. The waterproof layer of waterproof floor should be 200m higher than the ground, and the waterproof layer of bathroom wall with shower should be 1800 (L8m higher than the ground (L8 suggests the whole wall is waterproof).
6. Do the closed water test as required, and do it by sealing the riser (see L8 old post for the method of sealing the riser). It is suggested to do sealing water test after waterproofing, and then do local waterproofing again. If the waterproof layer on the ground is not damaged, the water closing test can be omitted.
