What is the specific waterproofing of the bathroom? How much is the height of the wall As well as craftsmanship?
Polyurethane waterproof coating general approach is as follows: 1, the ground to the direction of the ground to find slope, cement mortar or bean concrete can be, but the surface to be flat. Near the door slope is small, the gap near the slope, according to the specific situation to master. 2, the pipeline to wear the floor of the root, to strengthen the waterproof. Tube root construction seal seal, cement smoothing foot protection, brush waterproof coating when the paste from the wire to strengthen the layer 1 to 2 layers. The same measures around the floor drain. 3, the wall to deal with clean plain light without floating ash, small particles, wall ground junction to wipe the original angle or slope angle. Brush waterproof coating when the glass cloth to strengthen the layer 1 to 2 layers. 4, the total thickness of polyurethane waterproof coating requires more than 1.5 mm. Can not rely on the number of decisions. Root, corner reinforcement layer at the first brush, room temperature 4h dry, and then a large area of ??brushing, Tu scraping. There is no leakage scraping, bubbling phenomenon. Large area brushing 24h curing after brushing the next layer. 5, first brushing the facade after brushing the plane, the next brushing direction and the vertical again. The last time the film semi-curing, throwing coarse sand particles, easy to combine with the cement mortar in the future. 6, the ground waterproof layer should be painted out of the bathroom door outside the 300 wide. Waterproof surface waterproof layer should be higher than the ground 200, a shower bathroom wall waterproof layer should be higher than the ground 1800 (L8 recommended full wall waterproof).
