Where do you need to make waterproofing in the bathroom?

1. Inspect and accept the appearance, variety, specification, packaging, size and quantity of materials, and form corresponding acceptance records.

2. Check the quality certification documents of the materials and include them in the engineering and technical files.

3. After the material enters the site, the material inspection report shall be issued according to the specification.

4. When all the indicators of the physical properties of the material meet the standards, it is qualified; If an index does not meet the requirements of the standard, the index should be re-sampled in the tested product for re-inspection, and the re-test result meets the requirements of the standard, and the batch of materials will be judged to be qualified.

5. Waterproof material. There are three main categories: waterproofing membranes; 911 polyurethane waterproofing material; New polymer cementitious waterproofing material.

The last category is divided into general-purpose GS waterproofing materials and flexible JS waterproofing materials. Among them, the universal waterproof material is suitable for the waterproofing of the indoor floor and wall of the family.

1. Remove the original floor tiles and wall tiles (optional):

Remove the original wall tiles and floor tiles, this step is mainly for the secondary decoration of the old house, if it is a new house, you can skip this step, generally use a gray knife, and the scraper can also remove the original floor tiles.

2. Plugging the sewer pipes

The waterproofing of the bathroom is usually carried out after the completion of water and electricity, so the sewer pipe must be blocked before waterproofing to avoid blockage, and the small water pipe is blocked with a nut, and the large sewer pipe (such as the toilet sewer pipe) is blocked with PVC winding film.

3. Ground and wall leveling treatment

The leveling here is usually said to be ground plastering, the ratio of mortar cement and sand is: between 3, note that the thickness of leveling should not exceed 3cm. The horizontal and vertical errors should be controlled within 5mm.

4. Make a waterproof layer:

First of all, the wall will be slotted with cement to clean up the base layer, the details of the additional layer construction, in the pipe root, floor drain, yin and yang corners, and other weak parts that are easy to leak evenly brushed, painted waterproof paint twice, longitudinal and transverse brushed once, do a protective layer, to be waterproof and dry after the water release for 48 hours closed water test.

Bathroom waterproof height.

The waterproof height of the wall, usually when the general bathroom is waterproofed, the wall should be made about 30 cm high waterproof coating, so if the waterproof height is not enough to be 30 cm high or far more than 30 cm high, then the waterproofing of the bathroom is not harmonious. However, if the wall of this bathroom is a non-load-bearing light wall, then the waterproofing needs to be filled with waterproof paint to fill the entire light wall wall, so that it can be truly waterproof.

Waterproof coating height, we should pay attention to the coating is not just a few times when applying waterproof coating, in the bathroom waterproofing, the thickness of the waterproof coating film is required to be more than millimeters, so if it is smeared several times and still does not meet the height requirements, then the coating film is still not done well, and it needs to be reapplied. In addition, when applying paint, it is also necessary to pay attention to the fact that the paint that was brushed first must be repainted in a large area after drying at room temperature, and there can be no leakage and bubbling.

The ground must be done in full, and it is best to do it twice if possible.

The wall is generally made of 30CM, the bathing place is made of rice, and the conditional bathing place can be all done.

The bathroom is waterproof, the standard requirement is that the ground needs to be done, the wall should be at least meter, it is recommended to do the full height, if it is a lightweight wall, then it must be done full height.

At the same time, the most important thing to pay attention to when doing waterproofing in the bathroom is the yin and yang corner, the pipe, the sanitary ware, the floor drain and other places that are easy to leak, it is recommended to use the quick-setting repair mortar in the kitchen and bathroom waterproof slurry to repair and strengthen, and then use the permanent waterproof slurry as a whole to do waterproofing, so that the effect of special materials and special waterproofing is better.
