Teach you how to waterproof the bathroom - toilet, waterproof

The following points must be paid attention to in the waterproof decoration process of the bathroom: 1. Try not to damage the original waterproof layer. In the newly delivered building, the floors of the bathroom, bathroom and kitchen have waterproof layers made according to relevant specifications. Therefore, if the original waterproof layer is not damaged, leakage will generally not occur after occupancy. The common problem now is that some bathroom facilities will be added in the decoration, and various upper and lower water pipelines will be rearranged or moved, which has seriously damaged the original waterproof layer of the building. However, there is no repair or re-do waterproof construction. , so that the problem is only discovered after the leakage occurs. Experience: The waterproof layer is easily damaged when the ground is redecorated. If it is not repaired in time, leakage will occur in the future, affecting the neighbors. Therefore, attention should be paid to protecting the waterproof layer during decoration. If it is accidentally damaged, it should be repaired in time to avoid leaving hidden dangers. 2. Resurfacing the floor tiles to make the ground waterproof. If you need to replace the original floor tiles of the bathroom, after chiseling the original floor tiles, you must first use cement mortar to level the ground, and then do waterproof treatment, so as to avoid the uneven thickness of the waterproof coating. resulting in leakage. Before doing waterproofing, be sure to clean the ground and apply polyurethane waterproofing paint 2 to 3 times repeatedly. Experience: The joints between the wall and the ground and the ground joints of the pipes between the upper and lower water are the places where problems are likely to occur. We must urge the workers to deal with these edges and corners, and the waterproof coating must be applied in place. The decoration team is required to make cement mulch for the upper and lower water pipes of the kitchen and bathroom, and apply a polyurethane waterproof coating of 10 to 20 cm upward from the ground, and then redo the polyurethane waterproofing on the ground, and add the original waterproof layer to form a composite waterproof layer. to enhance water resistance. 3. Be sure to waterproof the walls. When the bathroom is bathing, the water will splash on the adjacent walls. If there is no protection of the waterproof layer, the adjacent walls and the opposite corner walls are prone to moisture and mildew. So be sure to do a good job of waterproofing the wall before laying the wall tiles. In general waterproof treatment, the wall should be waterproofed at a height of 30 cm, but for a non-load-bearing light body wall, the entire wall should be waterproofed, at least 1.8 meters high. Experience: The waterproof wall adjacent to the shower should also be 1.8 meters high. If a bathtub is used, the height of the waterproof coating on the wall adjacent to the bathtub should also be higher than the upper edge of the bathtub. 4. Use the 24-hour water storage test to accept the waterproofing. After the waterproofing project is completed, seal the door and the drain, and fill the bathroom floor with water to a certain level of liquid level, and make a mark. If the liquid level does not drop significantly within 24 hours , In particular, the roof of the downstairs home has no leakage, and the waterproofing is qualified. If the acceptance is unqualified, the waterproofing project must be redone as a whole, and then the acceptance is re-approved. Experience: For the acceptance of lightweight wall waterproof construction, a water spray test should be taken, even if the water pipe is continuously sprayed from top to bottom on the wall with waterproof coating for 3 minutes, and the other side of the wall is observed after 4 hours. Whether there will be infiltration phenomenon on the side, if there is no infiltration phenomenon, it can be considered that the wall waterproof construction is qualified. 5. Water pipe grooves in the wall should also be waterproof. During the construction process, when pipes, floor drains, etc. pass through the floor, the waterproof layer around the holes must be carefully constructed. The water pipes are buried in the wall, and the layout is reasonable. The water pipes are laid in grooves larger than the diameter of the pipes. The plastering in the grooves is smooth, and then the grooves are painted with polyurethane waterproof paint. Experience: The floor of the kitchen and bathroom must be sloped towards the floor drain, and the slope should be appropriately increased. When renovating the pipes in the kitchen and bathroom, try to avoid changing the original drainage and sewage pipes and the location of the floor drain, and avoid damage to the waterproof layer caused by re-arranging the pipes and cutting the floor leakage.
