Synopsis: Kitchens and bathrooms are often in a humid state, which requires higher waterproofing standards. The importance of waterproofing projects in kitchens and bathrooms is also of utmost importance.
Kitchens and bathrooms are often in a humid state, which requires higher waterproofing standards. The importance of waterproofing projects in kitchens and bathrooms is paramount. So, how is the waterproofing construction process for kitchens and bathrooms carried out? Let's take a look below.
For the construction process of waterproofing projects in kitchens and bathrooms, there are generally six points: 1. Cleaning the base layer: Use a scraper to remove the gray skin stuck to the leveling layer, and then use a broom to clean the dust, especially around the pipe roots, floor drains, and drainage outlets, which need to be cleaned carefully. If there is oil, it should be scrubbed off with a wire brush and sandpaper. The treatment of wall sides, corners, and door frames must be flat, smooth, and gentle. Areas with obvious grooves or bumps that affect the coating quality should be dealt with promptly or reported to the quality inspector for assistance.
2. Detail additional layers: First, use a waterproofing agent to treat the joints at the floor drains, pipe roots, inside corners, and outside corners where water leakage is likely. When applying on a large area, ensure even coverage without missing spots. The wall perimeter should be rolled with a height of 150mm, fully covering the area around the drainage pipes and floor drains.
3. First coat: Mix the materials according to the ratio and apply from the inside out, ensuring the thickness is uniform.
4. Second coat: Once the first layer has cured to a non-tacky state, apply the second coat using the same material ratio as the first layer, with the scraping direction perpendicular to the first.
5. After the second layer has cured, mix the coating materials according to the ratios of the previous two layers for the third coat, ensuring the final thickness is no less than 1.5mm. Before it cures, sprinkle fine sand on the surface of the coating to increase the bonding strength with the cement mortar overlay.
6. After the waterproof layer construction is completed and accepted successfully, a protective layer should be applied, which will extend the service life of the waterproof layer.
The above is the construction process for waterproofing projects in kitchens and bathrooms. Not only is the construction process important, but the quality of a waterproofing project also depends on the quality of waterproofing materials, the skills of the construction team, and every detail during the construction process. By addressing these aspects well, the ideal waterproofing effect can be achieved.
Synopsis: Recently, in order to accelerate the promotion and application of green building materials, support the development of the green building materials industry, enhance the quality of construction, and promote the green transformation of urban and rural construction, after public announcement with no objections, the Fuzhou Municipal Housing and Urban-Rural Development Bureau, the Fuzhou Municipal Finance Bureau, and the Fuzhou Municipal Bureau of Industry and Information Technology announced the "Fuzhou City Green Building Materials Product Information Directory."
