What are the requirements for bathroom waterproofing

1. Height: Before laying floor tiles, be sure to waterproof the wall. During the waterproofing process, the waterproof height of the wall should be 30cm. If it is not a load-bearing lightweight wall, the entire wall must be waterproofed and should be at least 60cm high.

2. Paint: Waterproof paint should comply with national standards and qualified products should be used. Waterproofing work at the joints between floors and walls is the most critical and is also the place where problems are most likely to occur. The corners of walls and floors must be coated with waterproof paint.

3. Floor tiles: Before laying floor tiles, be sure to clean the ground, smooth the ground with cement mortar, and then carry out waterproofing work. This can avoid uneven application of waterproof coating and leakage of waterproof coating. After the first coat of waterproof coating is completely dry, carry out the second waterproofing treatment. Only after the second coat of waterproof coating is dry can you lay tiles.

4. Grooves: In addition to the ground, the grooves of the internal water pipes must also be waterproofed. When pipes, floor drains, etc. pass through the floor, the waterproof layer around the holes must be carefully treated. The water pipes buried in the wall must be reasonably laid out, and the grooves larger than the pipe diameter must be laid, and waterproof paint must be applied in the grooves.

How to apply waterproof coating to bathroom

1. First, clean the construction ground and keep it dry, then start to apply the first coat of waterproof coating. Every place should be fully coated without any omissions.

2. After the first coat of paint is completely dry, apply the second coat of waterproof paint, then apply the film. When it is semi-cured, throw coarse sand on it and lay a protective layer.

3. Finally, conduct a water-tightness test.

What are the points to pay attention to in bathroom waterproofing

1. Whether it is the first renovation or the renovation of the bathroom, it must be cleaned and then leveled with cement mortar before waterproofing construction can be carried out. Otherwise, uneven application will cause water seepage.

2. When carrying out waterproofing construction, it is necessary to avoid damage to the ground due to factors such as fire prevention and waterproofing.

3. When carrying out waterproofing construction at the joints, you must be especially careful. It is best to apply several times to avoid omissions.

4. Paint usually needs to be applied three times, and each time you apply it, you must wait for the previous one to dry thoroughly before you can apply it again. Therefore, it is recommended to decorate in the early spring, because there is a lot of rain in spring, and waterproof materials are easier to dry, which has little impact on the construction effect.
