The decoration of the bathroom will directly affect our daily home life. It has the most contact with water, so waterproofing is particularly important. Once the leakage will bring great trouble to people, the neighborhood relationship is also a great challenge, then how to waterproof? Xiaobian collected a series of questions from netizens, authoritative experts gave answers, dear, don't Missed!
Question 1: The bathroom water and electricity are all walking on the wall, do not go to the ground, only do rigid waterproof and not flexible?
Experts answer: the bathroom wall is generally hollow brick wall, the deformation is large, it is not easy to use rigid waterproof material. The difference between rigid waterproof and flexible waterproof is mainly the ability to extend and adapt to structural changes. Whether hydropower is not a decisive factor. Relatively speaking, the overall performance of flexible waterproofing is better than rigidity. If it is a new house to be waterproof, the possibility of settlement and structural deformation is greater, it is recommended to choose flexible waterproof. If it is an old house, the structure is relatively stable, and the rigid waterproof material is generally used to meet the waterproof demand.
Question 2: How to make waterproof after destroying the original waterproofing of the bathroom? Is it waterproof with non-woven fabric? Is it waterproof with flexible waterproof? Is it waterproof under geothermal heat?
Experts answer: After the waterproof layer is destroyed, it must be completely re-waterproof. In response to the complex structure of the bathroom, waterproof coatings should be selected for waterproofing and flexibility. Should be waterproof on the geothermal.
Question 3: Does the bathroom bathtub need to be re-waterproof?
Expert answer: After the bathtub is removed, it depends on whether the bath function is retained. If there is a shower, it is natural to be waterproof, and it must be 1.8 meters high. If the bathing function is canceled, there is a clear water contact area such as a sink in the bathroom, so it is still necessary to make waterproof, but it does not need to be 1.8 meters, and the surface layer is 30cm high according to the specification.
Question 4: I would like to ask the experts, on my home purchase contract, the bathroom written by the developer has been waterproofed. Do you need to re-do it in this case?
Experts answer: All newly developed houses are waterproofed according to the specifications of the developers. If your home is a hardcover, you don't have to be waterproof. However, if it is a rough house, it is necessary to carry out hydropower transformation and renovation after delivery, which will destroy the original waterproof layer. Therefore, be sure to re-waterproof.
Question 5: My bathroom has been waterproofed three times, and there are sporadic mildews on the roof downstairs. Does it mean that my house is not waterproof?
Experts answer: The material is the foundation, the construction is the key, and the waterproofing is done three times. First, see if you are qualified waterproof material, and then see if the joint process is carried out in the construction process, and whether the waterproof coating layer reaches the design thickness three times.
Question 6: Please advise the Supreme, how high should the bathroom waterproof be? Because the waterproof of the bathroom in the house is not good. Therefore, the husband of the new house asked the bricklayer to make the waterproof 1.8 meters high. However, the bricklayer said that waterproofing can only achieve 20CM. If it is too high, after a few years, the cement will fall easily (because the waterproof layer is glue), so that the tile falls and the bricklayer is not responsible. Now I can't figure out what the husband said is right, or is the bricklayer right?
Experts answer: Your husband's point of view is correct, the bathroom according to the standard, the bathing area must be 1.8 meters, 20cm norm does not exist, even if the wall is not drenched, it should be 30cm high. As for the problem of tile shedding, it has nothing to do with the height of the coating. It is because the base is not treated for the post-laying during the construction process. The last time the waterproof layer is uncured, it needs to be sanded and napped to enhance The adhesion to cement mortar and ceramic tiles ensures that the tiles will not fall off during later use.
