Waterproofing is an important step in the decoration and affects everyday life. So, how can we make the waterproof perfect? ​​The following is a small series to learn, just four steps to be OK!
First, try not to damage the original waterproof layer in the newly delivered building, the floor of the bathroom, bathroom and kitchen have waterproof layer according to the relevant specifications, so it will not happen after the original waterproof layer is not damaged. Leakage. The common problem now is that the bathroom facilities in the renovation will be added and the various water and sewage pipelines will be re-arranged or moved. The original waterproof layer of the building has been seriously damaged. However, there is no repair or re-waterproof construction. So that the problem was discovered after the leakage occurred. Experience: The waterproof layer is easily damaged when it is refurbished. If it is not repaired in time, it will leak in the future and linger in the neighborhood. Therefore, after completing the hydropower transformation, it is necessary to do another waterproofing.
Second, re-lay the floor tiles to do the ground waterproof If you need to replace the original floor tiles of the bathroom, after the original floor tiles are cut, you must first use the cement mortar to level the floor, and then do waterproof treatment, so as to avoid the uneven thickness of the waterproof coating Causes leakage. Before doing waterproofing, be sure to clean the floor and apply it to 1.5mm repeatedly with indoor special waterproof coating. Experience: The seam between the wall and the ground and the joint between the water and the pipe on the ground are the most prone to problems. It is necessary to urge the workers to handle these corners and the waterproof coating must be applied. Require the decoration team to do the cement roots for the upper and lower pipes of the kitchen and bathroom. Brush the waterproof coating from 10 to 20 cm from the ground, then re-do the waterproof on the ground, plus the original waterproof layer to form a composite waterproof layer to enhance Waterproof.
Third, must be done on the wall waterproof bathroom bath water will splash on the adjacent wall, if there is no protection of the waterproof layer, the long-term past wall and the top corner wall are easy to mold mildew. Therefore, be sure to waterproof the wall before laying the wall tiles. Generally, the wall surface should be made of 80 cm high waterproof treatment, but the non-load-bearing light body wall should be waterproofed, at least 1.8 meters high. Experience: The wall surface adjacent to the shower location should be 1.8 meters high. If a bathtub is used, the height of the wall waterproofing paint adjacent to the bathtub should be higher than the upper edge of the bathtub. Experience: the floor of the kitchen and bathroom must be sloped to the ground, and the slope should be increased appropriately. When the pipes in the kitchen and bathroom are renovated, the original drainage and sewage pipes and floor drains should be avoided as much as possible to avoid damage to the waterproof layer caused by re-discharging the floor slab. leakage.
4. After waterproofing, use 24 hours “closed water test†to check the waterproof. After the waterproof project is finished, seal the door and the drain, fill the bathroom floor with water to reach a certain level, and mark it within 24 hours. If there is no obvious drop in the liquid level, there is no leakage in the roof of the house downstairs, and the waterproofing is qualified. If the acceptance is unqualified, the waterproof project must be redone and re-inspected. Experience: For the acceptance of lightweight wall waterproof construction, the water spray test should be adopted, that is, the water pipe should be sprayed continuously from top to bottom for 3 minutes on the wall surface of the waterproof coating, and another wall after 4 hours. Whether there will be penetration on the side, if there is no penetration, the wall waterproof construction acceptance is considered qualified.
