The ground waterproofing project is a concealed project. Although the project is very small, it will have a significant impact on the future. Many owners who have just contacted home improvement equipment are not familiar with waterproof materials on the floor. Here, we will introduce which waterproof materials are on the ground. 1, asphalt waterproof material. The natural asphalt, petroleum asphalt and coal asphalt as the main raw materials, made of asphalt linoleum, asphalt tire felt, solvent-based and water emulsion bitumen or asphalt rubber coatings, ointments, with good adhesion, plasticity, Water resistance, corrosion resistance and durability. 2, rubber plastic waterproof material. With neoprene rubber, butyl rubber, ethylene propylene diene monomer, polyvinyl chloride, polyisobutylene, and polyurethane as raw materials, it can be made into elastic tireless waterproof membrane, waterproof membrane, waterproof coating, coating material and ointment, cement Sealing materials, such as sealing tapes, have high tensile strength, high elasticity and elongation, good adhesion, water resistance, and weather resistance. They can be used coldly and have a long service life. 3, cement waterproof material. Admixtures with a coagulative effect on cement, such as water repellents, air entrainers, and swelling agents, can increase the hydrophobicity and impermeability of cement mortars and concrete; and promote coagulation with cement and sodium silicate as base materials. Mortar, can be used for underground engineering plugging and waterproofing. 4, metal waterproof material. Thin steel plate, galvanized steel plate, profiled steel plate, coated steel plate, etc. can be directly used as roofing panels for waterproofing. Thin steel plates are used for metal waterproofing of basements or underground structures. Thin copper plates, thin aluminum plates, and stainless steel plates can be used as waterproofing strips for building deformation joints. The connection of the metal waterproof layer is to be welded and painted with a rust-proof protective paint. Material price: Due to the large number of pipes and small areas in kitchens, bathrooms, etc., the home improvement is particularly suitable for the use of cement-based waterproof coatings. These products are water-based coatings, non-toxic, harmless, non-polluting, simple and quick construction, and bonding with cement substrates. , long service life, strong waterproof effect, moderate price and significant features. The price of this kind of waterproof material is usually: general type (ie rigid) 20kg/set of 280-350 yuan; flexible type 20kg/set of 350-480 yuan. Employment price: The family is generally the kitchen floor and the walls of the bathroom should be waterproof, the standard price of 65 yuan / square meter. If skilled workers are asked to construct, the market price of waterproofing will be around 60-100 yuan/square meter, accounting for about 1% of the renovation cost. Waterproof area calculation: bathroom waterproof area (m2) = [(groom bathroom perimeter - width of the door) × 1.8m (high) + (floor area)]; kitchen waterproof area (m2) = [(kitchen ground Perimeter - width of the door) x 0.3 meters (height) + (ground area)]. In the first step, we should observe the bathroom's water circuit and reconstruct it in light of the actual situation. We have a detailed understanding of the hidden project. After a good plan is determined, the hydropower and heating pipes will be laid and flattened again. Secondly, on the grass-roots level, the existing decoration materials should be cleaned before the toilet works for waterproofing, and then the surface should be paved with cement slurry and then treated with water. The second step, when doing the waterproof layer, should pay attention to whether the waterproof coating brushing is uniform, the thickness of the waterproof layer should be more than 1.5mm, pay attention to the dead angle, joints, waterproof treatment. After the completion of the construction, a 24-hour water-blocking test should also be conducted: Block all sewers in the toilet, build a 25cm-high hurdle at the entrance, and inject water at a height of 20cm. After 24 hours, observe whether or not water leakage occurs. There should be timely repairs. In the third step, after the waterproof coating has formed a waterproof film 5-7 days after the water-blocking test, a layer of cement mortar shall also be applied on the waterproof coating layer. In doing so, one can effectively protect the waterproof coating, the second conveniently tiles, and at the same time, it can have good leakproof and waterproof pressure on the pipeline. The last step is the laying of walls and floor tiles. Pvc Doors,Solid Pvc Door,Pvc Bifold Door,Pvc Concertina Doors Foshan QI'AN Fireproof Shutter Doors Co., Ltd , https://www.fsqianfiredoor.com
