The bathroom is the contact we need every day. It is a very important part of life. While bringing convenience to the family, it may also lead to a series of contradictions, such as disputes caused by bathroom leaks. How to eliminate these problems, decorate a comfortable bathroom, the next small series to introduce you how to waterproof in the decoration process.
The following points must be noted during the waterproof renovation of the bathroom:
First, try not to damage the original waterproof layer
In the newly delivered buildings, the floor of the bathroom, bathroom and kitchen have waterproof layers according to the relevant specifications. Therefore, leakage will not occur after the original waterproof layer is not damaged. 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, we must pay attention to the protection of the waterproof layer during the decoration. If it is accidentally damaged, it should be repaired in time to avoid leaving hidden dangers.
Second, resurfacing the floor tiles to do ground waterproofing
If you need to replace the original floor tiles of the bathroom, after you have cut the original floor tiles, you must first level the floor with cement mortar and then do waterproof treatment, so as to avoid leakage due to uneven thickness of the waterproof coating. Before doing waterproofing, be sure to clean the floor and apply it repeatedly with polyurethane waterproof coating for 2 to 3 times.
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 10 to 20 cm polyurethane waterproof coating from the ground, then re-do the polyurethane waterproofing, and add the original waterproof layer to form a composite waterproof layer. To enhance water resistance.
Third, must do wall waterproofing
When the bathroom is bathed, water will splash on the adjacent wall. If there is no waterproof layer protection, the partition wall and the opposite corner wall will be mild and mildewed. Therefore, be sure to waterproof the wall before laying the wall tiles. Generally, the wall surface should be waterproofed to a height of 30 cm, but the non-load-bearing light-weight wall should be waterproofed, at least 1.8 m 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.
Fourth, use 24 hours "water storage test" acceptance waterproof
After the waterproofing project is completed, seal the door and the water outlet, fill the bathroom floor with water to reach a certain liquid level, and make a mark. If there is no obvious drop in the liquid level within 24 hours, the roof of the house downstairs does not occur. Leakage, 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.
5. The water pipe groove in the wall should also be waterproof.
During the construction process, when the pipeline, floor drain, etc. pass through the floor, the waterproof layer around the hole must be carefully constructed. The water pipe is buried in the wall to make a reasonable layout. The pipe is uniformly made to be larger than the pipe diameter, the plaster in the groove is smooth, and then the polyurethane waterproof coating is brushed in the groove.
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.
Pneumatic Toilet Tank is a high-tech toilet equipment that uses pneumatic technology to control flushing. Compared with traditional mechanical hidden water tanks, it has higher flexibility and reliability.
The pneumatic toilet cistern is mainly composed of a water tank, an air gauge, a cylinder, a water valve and buttons. When the button is pressed, the air gauge will automatically release the compressed air into the cylinder, push the water valve to open and release the water into the toilet basin. When the air in the barometer is completely released, the water valve will automatically close, stopping the inflow of water.
The advantages of the pneumatic toilet tanks include: the amount of flushing water can be adjusted freely, the flushing effect is better, the service life is long, it is easy to clean, and it is more water-saving. It can control the amount of flushing water by adjusting the air gauge, so as to adapt to different toilet basins and flushing requirements. In addition, the pneumatic hidden water tank does not require any buttons or handles to be touched by hand, which also makes it more hygienic.
