Ground treatment: 1. Brush the waterproof paint for the first time. Before construction, ensure that the construction site is clean and dry, and the waterproof coating should be coated with no omission, firmly combined with the base layer, no cracks, no bubbles, and no falling off. The coating height is consistent, and the thickness should meet the requirements of the product.

PS: Floor drains, wall corners, pipe heels and other joints should be painted with high elasticity and flexible waterproofing, because the joints between the wall and the floor of the bathroom will be displaced and are most likely to seep water.

2. Brush the waterproof paint for the second time. Note that there needs to be a certain time interval between the second waterproof coatings, and the second pass can only be carried out after the paint is dry, and the specific time depends on the coating. If the interval is too short, the waterproof effect will be greatly reduced.

3. Lay a protective layer. In order to prevent the subsequent construction from damaging the waterproof layer, it is necessary to lay a protective layer on the surface of the waterproof coating. The protective layer should be completely covered with the waterproof layer, no omission, firmly combined with the base layer, no cracks, no bubbles, and no falling off.

4. Closed water test. During the closed water test, the waterline at the ground point should not be less than 2 cm, and it should be stored for at least 24 hours, and it should be qualified only after observing that there is no leakage. If there is a leak, it needs to be redone, and you must not be negligent.

6.Don't be too troublesome.

Wall Treatment: 1If the bathroom has a shower room, the waterproof should be 180cm, and if there is a bathtub, the waterproof height of the wall adjacent to the bathtub should be 30cm higher than the bathtub

2. After the waterproof layer is done, a certain amount of time should be left to make the waterproof layer better integrated with the building, and then the protective layer on the waterproof layer and then paved with floor tiles.

4. Waterproofing is a systematic project, and the causes and treatment methods are different in each place. Materials are the foundation, construction is the key, and follow-up service is the guarantee.

After the bathroom decoration is completed, the bathroom waterproofing will be started.

Indoor bathroom waterproofing tips:

1. The interior decoration must be waterproof, and the wall waterproofing should be done before laying the wall tiles. The general treatment method is to make the wall waterproof to 30 cm high, but at present, the bathroom of Chinese residential houses is generally used as a shower room, which requires the entire wall to be made meters high. If it is a lightweight wall, it is better to paint it in its entirety, from the bottom to the top.

This kind of waterproofing is comprehensive, and it can be waterproof at one time.

2. Indoor waterproofing, the joints between the wall and the ground and the joints of the pipes between the water and the water are the most prone to problems, we must urge the workers to deal with these edges and corners, and the waterproof coating must be applied in place. Each work point must supervise the construction master to do fine work.

3. Interior decoration. If you need to replace the original floor tiles in the bathroom, after chiseling the original floor tiles, you must first level the ground with cement mortar, and then do waterproof treatment, so as to avoid leakage caused by the uneven thickness of the waterproof coating, and also avoid affecting the service life of the material because of the uneven base layer, and the waterproof material plays the greatest role.

4. Interior decoration, try not to destroy the original waterproof layer. In the newly delivered buildings, the ground is generally made of waterproofing, so try not to damage the original waterproofing layer. Be careful at each construction site, because some waterproofing materials are relatively thin, and a little carelessness may damage the waterproofing layer.

5. For interior decoration, the decoration team is required to do a good job of cement mulch for the upper and lower water pipes of the bathroom, brush 10 to 20 cm of waterproof paint from the ground, and then redo the waterproof on the ground, plus the original waterproof layer, to form a composite waterproof layer to enhance waterproofness.

6. Interior decoration, the water pipe groove in the wall should also be waterproof, and the waterproof layer around the hole must be carefully constructed when the pipe, floor drain and so on pass through the floor slab during the construction process. Buried water pipes in the wall, so as to achieve a reasonable layout, lay water pipes are made of grooves larger than the pipe diameter, plastering in the groove is smooth, and then brush waterproof paint in the groove.

7. With 24 hours of "water storage test" acceptance waterproofing, after the waterproof project is completed, seal the door and sewer, fill the bathroom ground with water to reach a certain liquid level height, and make a mark, if the liquid level does not drop significantly within 24 hours, especially the roof of the downstairs house does not leak, the waterproof is qualified.

Bathroom waterproofing is done after the installation of water and electricity, before the tiles and floors are laid. Before waterproofing, cement mortar can be used to seal all the parts of the water pipe through the wall, but because the cement mortar shrinks greatly and the viscosity of the pipeline material is poor, in order to avoid leakage of water at the pipe part of the wall in the future, it is best to use the plugging king or nozzle grouting material to block all the parts of the water pipe through the wall. Wait until the blocked material is completely dry (about 24 hours later) and apply waterproofing.
