Ask for advice on how to waterproof the bathroom

The bathroom has been tiled is not able to do waterproofing on the tile, first of all, I will tell you about the process of bathroom decoration, it is necessary to first carry out water and electricity renovation and then do waterproofing, and then close the water test, and finally paste the tile to install sanitary ware and decoration. Waterproofing needs to be done on the cement-based surface, so that the waterproof layer can achieve a good waterproof effect.

Use diluted concrete to repair and level the damaged, ground water pipes, wall water pipes and other places that need to be repaired, and wait for the cement to basically solidify and dry; Clean the ground and wall, clean the bottom with water and paint it evenly, and use the bristle brush to paint the waterproof paint longitudinally and horizontally after the water does not leak and basically dry, and brush it 3 times.

1. Use tools such as brushes, scrapers or shovels to clean up the base layer that needs to be re-waterproofed, and clean up the raised particles of the original waterproof layer and the floating ash garbage on the ground. (This step needs to be careful and strict).

2. After preparing the base layer (according to the requirements of different waterproof materials), first use flash slurry to block the slotted pipe joints with the waterproof layer and fill and smooth them.

3. According to the instructions for the use of waterproof coating (different waterproof materials and methods are different), use a stirrer to stir until it can be used.

4. Carefully and evenly brush the waterproof weak parts that are easy to leak such as wall corners, yin and yang corners, pipe roots, and floor drains.

5. Use a roller brush to apply waterproof paint to a large area for the first time. It is best to make rice on the wall of the kitchen sink; The height of the bathroom shower wall should be at least 30 meters, and the other positions should be at least 30 cm high, and the place with a bathtub should be 30 cm higher than the bathtub. (This prevents domestic water from splashing on the wall and penetrating into the wall, causing moisture to recur on the back of the wall.)

6. After the second waterproof coating is dried, the closed water test is carried out. (generally 48 hours) during the closed water test, the test effect can be checked to the downstairs bathroom to check whether there is any water leakage on the roof.
