Five points for waterproof decoration in bathroom
Bathrooms are a very important part of people’s daily life. Not only do they bring unnecessary economic losses to many families, but they may also destroy the original and harmonious neighborhood relationship. How can we prevent leakage events? How to pay attention to the waterproof problem in the bathroom decoration?
The following points must be noted during the waterproof decoration of the bathroom:
First, try not to destroy the original waterproof layer
In newly delivered buildings, the floors of bathrooms, bathrooms, and kitchens have waterproof layers according to the relevant regulations. Therefore, if the waterproof layer is not damaged, leakage will not occur after occupancy. The common problem now is that during the renovation, some bathroom bathing facilities will be added and a variety of upper and lower water lines will be re-arranged or moved. It has already seriously damaged the original waterproof layer of the building, but it has not been repaired or re-waterproofed. So that the problem was discovered after the leakage occurred.
Experience: The waterproof layer is easily damaged when the floor is redecorated. If it is not repaired in time, leakage will occur in the future, affecting neighbors. Therefore, in the decoration should pay attention to protect the waterproof layer, if accidentally damaged, repair in time to avoid hidden dangers.
Second, re-floor tiles to do the ground waterproof
If it is necessary to change the original floor tiles of the bathroom, after the original floor tiles are chiseled away, the ground must be leveled with a cement mortar first, and then the waterproof treatment should be performed so that leakage of the waterproof coating due to uneven thickness can be avoided. Before doing waterproofing, be sure to clean the floor and apply 2 to 3 times repeatedly with a polyurethane waterproof coating.
Experience: The seams between the wall and the ground and the seams between the pipes and the water are the most prone to problems. We must urge the workers to handle these corners. The waterproof coating must be applied in place. The decoration team is required to provide cement mulch to the upper and lower water pipes in the kitchen and bathroom. Brush a 10 to 20 cm polyurethane waterproof coating upward from the floor, and then re-do the polyurethane waterproofing on the ground, and add the original waterproof layer to form a composite waterproof layer. To enhance waterproofness.
Third, we must do wall waterproof
When the bathroom takes a bath, the water will splash on the adjacent wall. If there is no protection of the waterproof layer, the partition wall and the diagonal corner wall will become mildly damp. So be sure to waterproof the walls before you apply the wall tiles. In the general waterproofing process, the wall surface is to be treated with a waterproof height of 30 cm. However, for a non-load-bearing lightweight wall, the entire wall should be waterproofed, and at least 1.8 meters high should be achieved.
Experience: The waterproof surface of the wall adjacent to the shower location is also 1.8 meters high. If a bathtub is used, the height of the waterproof paint on the wall adjacent to the bathtub is also higher than the upper edge of the bathtub.
Fourth, use 24 hours "storage test" acceptance waterproof
After the waterproof project is completed, close the door and the water outlet, fill the bathroom floor with water to a certain level, and make a mark. If there is no obvious drop in the liquid level within 24 hours, the roof of the house below the downstairs does not occur. Leakage, waterproof to be qualified. If the acceptance is unqualified, the waterproofing project must be redone and re-inspected.
Experience: For the acceptance of light-weight wall waterproof construction, a water-spray test should be conducted, even if the water pipe is sprayed continuously from top to bottom for 3 minutes on the waterproof paint wall, and after 4 hours, observe the other wall. Whether the side will appear infiltration phenomenon, if there is no penetration phenomenon can be considered that the wall waterproof construction acceptance.
Fifth, the wall groove should also be waterproof
During the construction process, when the pipeline, floor drain, etc. cross the floor, the waterproof layer around the hole must be seriously constructed. Buried water pipes in the wall, so that a reasonable layout, the laying of water pipes shall be greater than the diameter of the groove, smooth plaster groove, and then brush the groove in the polyurethane waterproof coating.
Experience: The floor of the kitchen and bathroom must be leaked on the slope, and the gradient should be increased. When the pipes in the kitchen and bathroom are renovated, the original drainage and sewers and the position of the floor drain should be avoided as much as possible to avoid damage to the waterproof layer due to the re-routing of the floor slab. leakage.
