How to make the bathroom and kitchen waterproof? Who can talk about it?

Because of the structure and use of the bathroom, the complexity and importance of waterproof in the bathroom are determined. How to waterproof the bathroom is a problem that everyone is very concerned about. Edit this paragraph (1) and pour the reinforced concrete floor. (2), 1: 3 cement mortar to find the slope layer, the thinnest part is 20mm thick, and the slope is floor drain, once leveling. ③ Acrylic polymer cement-based waterproof slurry. (4), 30㎜ thick hardened cement mortar bonding layer. Fold and edit this technological process. Basic treatment and cleaning should be carried out. Combined with the details, the water storage test of acrylic waterproof layer with additional layer of leveling layer is carried out. Secondary water storage test of protective layer construction. 1. Check the elevation of kitchen and bathroom correctly, and pay great attention to the elevation position of floor drain. 2. Carefully check the quality of the floor drain and the wall hole at the pipe root, and the wall hole shall be dense and qualified. During the construction of leveling layer, the pipe root shall be caulked as required. Waterproof construction of toilet 3. Yin and Yang angles should be round, straight and flat. 4. Construction of leveling layer: If there are gaps, cracks and unequal defects in the base surface, cement mortar shall be used to repair and level them. Make the base surface firm, smooth and clean, free of dust, grease, wax, release agent and other sundries. 5. The waterproof layer can only be constructed after the leveling layer is dry, and it should be fireproof and waterproof during construction. Construction personnel should wear soft-soled shoes. 6. After the waterproof layer is completed, protect the finished product, and no one is allowed to walk around. After inspection and confirmation, the concealed engineering acceptance visa can be handled and the next working procedure can be constructed. 7. After the waterproof construction is completed, the water storage test is carried out, and it is qualified if it does not leak for more than 24 hours. After the equipment installation is completed, the secondary water storage test is carried out. 8. The bathroom should be treated by lowering the board or the bathroom with caisson structure needs these treatments: the construction method of caisson bathroom is as follows: 1. When the ground sinks, do two waterproof measures, one is rigid and the other is flexible. A: Also, do a 48-hour closed water test. B: Open a round hole with a diameter of 20mm at the lowest position between the vertical pipe and the caisson floor in the bathroom, and insert a pipe with a diameter of 20mm and a depth of 4mm at the opening position. The drainage pipe points to the center of the caisson floor in the bathroom, which is convenient for the bathroom to install the caisson waterproof device. C, use cement mortar as a protective layer on impermeable waterproof coating, requiring the surrounding height, and the position where the waterproof device body is installed is the lowest. After the cement mortar protective layer is dry -2, install the upper and lower water pipes. Install the waterproof device body and cover the body with pebbles to ensure that the accumulated water in the caisson can be discharged to the riser smoothly. 3. Fill the sand, and pile it 5 cm below the ground for compaction. 4. spread cement and fill it. 5. Be waterproof at the threshold of the bathroom. 6. Floor tiles. Matters needing attention in this paragraph 1. Try not to destroy the original waterproof layer. If the original waterproof layer is not destroyed, there will generally be no leakage after moving in. But when the ground is renovated, the waterproof layer is easy to be destroyed. If it is damaged carelessly, it is best to use Lancome plugging device for plugging and repair it in time to avoid leaving hidden dangers. 2. Re-paving floor tiles should be waterproof. If it is necessary to replace the original floor tiles in the bathroom, after roughening the original floor tiles, the ground must be leveled with cement mortar first, and then waterproof to prevent the waterproof coating from leaking due to uneven thickness. Be sure to clean up the floor before waterproofing, and brush it with Lancome home improvement waterproof coating for 2 to 3 times. When taking a bath, be sure to let the bathroom with waterproof wall splash water on the adjacent wall. Without the protection of waterproof layer, the next wall and the opposite corner are easy to be damp and moldy. Be sure to waterproof the wall before sticking the wall brick. Usually, in waterproof treatment, the wall should be waterproof with a height of 30 cm to prevent water from infiltrating into the wall. But for non-load-bearing light wall, the whole wall should be waterproof, at least 1.8 meters high. If you use two shower screens at home, the two walls that are connected together should also be painted. If a bathtub is used at home, the height of the waterproof coating on the wall adjacent to the bathtub is higher than the upper edge of the bathtub. 4. The water pipe trough on the wall should also be waterproof. In the process of construction, when pipes and floor drains pass through the floor, the waterproof layer around the hole should be carefully prepared. Water pipes should be buried in the wall and have a reasonable layout. All laid water pipes should be made into grooves with a diameter larger than the pipe diameter, and plastering in the grooves should be smooth, and then waterproof coating should be painted in the grooves. 5.24-hour "closed water test" after the completion of the waterproof project, seal the door and drain, fill the toilet floor with water to a certain height, and mark it. If the liquid level does not drop significantly within 24 hours, and there is no water seepage in the ceiling downstairs, the waterproofing is qualified. If the acceptance is unqualified, the waterproof project should be redone as a whole and re-accepted. 6. Keep the sewer unblocked. All sewer pipes in the bathroom, including floor drains and sanitary ware sewer pipes, should be kept unobstructed. The construction method of this section is 1. Ground treatment Before waterproof treatment, the ground must be leveled first. If the ground is uneven, it may affect the waterproof effect, and it may also lead to cracking and leakage due to uneven thickness of waterproof paint. Floor drain, corner, pipe heel and other joints should be painted with high elasticity and flexibility, because the joints between the bathroom wall and the ground will be displaced, which is the most prone to water leakage. 2. The wall surface treatment should be coated with waterproof coating with a height of about 30cm to prevent water from infiltrating into the wall surface. If there is a shower room in the bathroom, it should be waterproof to 180cm. If there is a bathtub, the waterproof height of the wall adjacent to the bathtub should be 30cm higher than that of the bathtub. 3. After the waterproof layer is completed, it is necessary to set aside a period of time for the waterproof layer to better integrate with the building, then make a protective layer on the waterproof layer, and then lay the floor tiles. In the process of construction, we must not be careless. 4. Waterproof construction is a concealed work, and subsequent construction may also destroy the waterproof layer. If the floor tile has been paved, don't smash the floor tile, and plug all the cracks with professional waterproof materials for waterproofing. It is also suitable for the waterproof project after the waterproof layer of the bathroom fails. Waterproofing is a systematic project, and the reasons and treatment methods are different in every place. Materials are the foundation, construction is the key and follow-up service is the guarantee. The choice of materials and waterproof materials in this section is an important step in bathroom decoration. How to do a good job in toilet waterproof measures is a key. Of course, a good waterproof material in the bathroom has a certain protective effect, and it is also closely related to the actual waterproof construction. In the bathroom decoration, how to make the bathroom waterproof and how to choose the waterproof material of the bathroom, after reading this article, I think these are no longer the problems of your decoration. 1. Selection of waterproof materials for toilets Most of the reasons for water leakage in toilets are caused by waterproof materials in toilets. There are many unqualified materials on the market. For friends who are not proficient in decoration, it is easy to buy inferior bathroom waterproof materials. Therefore, Bian Xiao suggested that it is best to invite professionals to accompany you when purchasing decoration materials. At present, there are two categories of toilet waterproof materials on the market. One is polyurethane waterproof coating; The other is polymer cement-based waterproof coating. Polymer cement-based waterproof coatings have become the protagonist of the market, and polyurethane waterproof materials used to be the main force in the waterproof market, with good waterproof performance. However, environmental protection is also one of its shortcomings. As one of the emerging waterproof materials, cement mortar is a popular waterproof material for toilets. General waterproof materials are usually recommended for kitchen and bathroom waterproofing. 2. The toilet waterproof construction should be handled at the grass-roots level, and the ground should be flat and dry, which is conducive to waterproof construction. When laying waterproof coating, it should be painted evenly, and there should be no brush leakage, bulging and falling off. The thickness of waterproof coating is appropriate, too thick or too thin will affect the waterproof effect diagram. When making the bathroom waterproof, the joint between the dead corner and the water pipe is also a very important place. After the waterproof project is completed, it should be inspected for remediation.
