1. Foundation 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 coating. Joints of floor drains, corners, pipe roots, etc. Flexible waterproof coating with high elasticity should be adopted, because the joint between the bathroom wall and the ground will be displaced, which is the easiest to leak water.
2. Wall treatment
The wall should be coated with waterproof paint, with a height of about 30cm to prevent water from infiltrating into the wall. If there is a shower room in the bathroom, waterproof paint should be painted, and the height is about 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. It is inevitable that water will splash on the bathroom wall when it is wet, so we must pay attention to the details of the wall to prevent water from seeping out of the wall. The wall should also be coated with waterproof paint, with a height of about 30 cm.
3. Leave a certain time after the waterproof layer is finished, so that the waterproof layer can be better integrated with the building, then make a protective layer on the waterproof layer, and then lay the floor tiles. In the process of construction, don't be careless and try to protect the waterproof layer.
4. Waterproof construction is a concealed work, and subsequent construction may also destroy the waterproof layer. If the floor tile has been laid, don't smash it. Use professional caulking waterproof materials to plug all gaps and do waterproof work well. It is also suitable for the waterproof project after the waterproof layer of the bathroom fails.
5. Waterproofing is a systematic project, and the reasons and treatment methods vary from place to place. Materials are the foundation, construction is the key and follow-up service is the guarantee.
6. Close the water for 48 hours, and the water injection height is greater than 30 mm.. 24 hours. No problem. If the time is longer, the owner will be more practical, and one more day will be enough. If there is no leakage, it is qualified;
After 7.24 hours or 48 hours, measure whether the water level drops with a tape measure, and immediately notify rework if there is water leakage;
8. Details that are easy to ignore but must be dealt with emphatically-the root of the pipeline is treated as a splayed angle, and the inner angle is treated as 10mm radian, so as to block all the possibility of water leakage and seepage!
All of the above are about the waterproof of the bathroom and what should be done. I hope it helps you!
