First, repave the floor tiles.
When the kitchen and bathroom floor is decorated, the waterproof layer is most likely to be destroyed. When specialization, try to protect the original waterproof layer. Once damaged, it should be repaired in time and the waterproof layer should be made again.
When replacing the floor tile, the original floor tile should be leveled with cement mortar, and the mortar should be evenly coated with waterproof coating on the wet base surface with a brush, scraper or roller to prevent leakage and sand holes, and then the second layer should be coated after the first layer is dry. During construction, pay attention to the intermittent mixing of mud to prevent precipitation, and the mixed mud should be used up within 20-40 minutes.
Second, the wall adjacent to the bathing equipment.
When the washbasin and sink are used, water will splash on the adjacent walls. If there is no waterproof protection, the wall is easy to be damp and moldy. Therefore, before laying the tiles in front, we must do a good job of waterproofing the wall.
Non-heavy lightweight wall should be at least 1.8 meters high, and it is best to waterproof the whole wall. The waterproof wall adjacent to the shower position should also be 1.8m high, and the waterproof paint on the wall adjacent to the bathtub should be higher than the upper edge of the bathtub.
Three, the joint between the wall and the ground, water pipes and the ground
Leakage mostly occurs at the pipe root, floor drain, sanitary ware and yin-yang corner passing through the floor. The reason is that the pipe root, floor drain and other parts are loose, the bonding is not firm, the coating is not tight or the waterproof layer is partially damaged, and the length of the parts is not enough. These edges and corners are the easiest to leak water.
Attention should be paid to the construction of detail nodes in weak parts, and waterproof coatings must be painted in place. When pipes, floor drains, etc. When crossing the floor, the waterproof layer around the hole must be carefully constructed. The upper and lower water pipes are protected by cement, and the waterproof coating 10 ~ 20cm is applied upward from the ground, and then the waterproof layer is made on the ground to form a composite waterproof layer to enhance the waterproof performance.
Fourth, there are walls with buried water pipes.
When the water pipe is buried in the wall, a groove larger than the pipe should be made, and the plaster in the groove should be smooth, and then waterproof coating should be brushed in the groove for waterproof treatment.
Fifth, sewage outlets and floor drains.
The floor of the kitchen and bathroom must be tilted to the floor drain, so that the drainage is smooth and there is no water accumulation. The waterproof material of the bathroom is particularly important. When decorating, try to avoid the original drainage pipes and floor drains.
