Why do bathrooms have to be waterproof?
Waterproofing in bathroom is the most important part of waterproofing in home decoration. Leakage between bathrooms will bring great annoyance to the owners'lives - the sewage from the roof flows down the pipeline and slab joints, wetting the roof walls, resulting in powdered walls and scattered tiles; difficult waterproof renovation construction, interfering with normal life, not only painstaking and costly, but also easy to form panic in neighborhood relations.
Why does the kitchen have to be waterproof?
At present, developers do not arrange floor leakage in the kitchen at all, and water flows directly from the sewer. However, the kitchen has been in a humid environment for a long time by scrubbing the air and splashing. Water will infiltrate the whole wall through the joints of floor tiles and cement mortar. Water vapor will penetrate into the cabinet through the opening of the joints between the cabinet and the wall, causing the deformation of the board. At the same time, the wet environment will lead to safe use of electricity. Therefore, the kitchen waterproof sloppy.
What are the waterproof construction procedures and specifications?
(1) Do not destroy the original waterproof layer
The original waterproof layer is easy to be damaged in the renovation. If it is not repaired in time, leakage will occur in the future, endangering the neighborhood. Therefore, when decorating, we should pay attention to the maintenance of waterproof layer, if not carefully destroyed, we should repair it in real time, in order to avoid leaving hidden dangers.
(2) Waterproofing the floor before laying floor tiles
Before waterproofing, the floor should be cleaned and cleaned. It is best to apply polymer waterproofing slurry evenly, and then lay floor tiles after 24 hours of drying. The joint between the wall and the ground and the joint between the upper and lower water pipelines on the ground are most likely to present leakage problems. Flexible waterproof paint is recommended, and the paint should be smeared in place.
(3) Waterproof wall
When taking a bath, water will splash on the adjacent wall. If there is no waterproof layer on the wall, the adjacent wall and the corner wall are prone to damp and mildew.
So before laying wall tiles, do a good job of wall waterproofing. In ordinary waterproofing treatment, the wall should be waterproofed at a height of 30 centimeters, and the whole wall should be waterproofed at least to 1.8 meters.
The wall waterproofing near the bathroom location should also be 1.8 meters high. If the bathtub is used, the height of the wall waterproofing paint adjacent to the bathtub is higher than the upper edge of the bathtub.
(4) Waterproof acceptance
After the waterproofing works are completed, the doors and sewers are sealed, the bathroom floor is filled with water to reach the established water surface height, and the water surface is marked. If the water surface does not fall clearly within 24 hours, the roof of the downstairs house does not leak, the waterproofing will pass. If the acceptance fails, the waterproofing project must be completely redone, and then stop acceptance again.
The acceptance of wall waterproofing construction should be subject to waterproofing test, that is, the water pipe sprays discontinuously from top to bottom for 3 minutes, and after 4 hours, observes whether the other side of the wall will show infiltration phenomenon. The non-infiltration phenomenon is the pass of wall waterproofing construction acceptance.
Code for Construction of Waterproof Layer
Waterproof coatings are fully coated, no omissions, strong bonding with the base, no bubbles, no cracks, no delamination, smooth appearance, basic difference of painting height of roll-up parts, thickness must meet the requirements of product rules.
