How to deal with the waterproof of bathroom in Foshan's new house decoration?

1, do a good job at the grass-roots level. Usually, the ground is covered with cement mortar, but there are some special circumstances, such as the pipeline is not buried well and the ground is uneven. Therefore, the waterproof practice of the bathroom requires that the grass-roots level is flat, the surface is smooth and firm, and there can be no hollowing, sanding and cracking. The moisture content of base course should meet the construction requirements of waterproof materials, and should not exceed 9%.

2. The flashing slope of the leveling layer should be 2%, and the pipe root against the wall should be 5% (1: 20) to avoid water accumulation here.

3, highlight the ground and the wall pipe root, floor drain. Drain, Yin and Yang Angle and other parts prone to leakage, local special plugging treatment should be done.

4. Stir the coating evenly, open the coating packaging barrel, and fully stir with a blender for about 5 ~ 10 minutes until the material contains no particles and no precipitation. According to the waterproof practice of toilet, mechanical stirring is generally used, but manual stirring is not suitable.

5. According to the standard toilet waterproof practice, the first coating: the waterproof coating is evenly coated on the primed base surface with a plastic or rubber scraper, with a thickness of 0.6mm and a uniform coating amount of 0.6 ~ 0.8 kg/m2. Operation should be based on the waterproof construction scheme of the bathroom, with the wall surface first and the ground then the operation from the inside out, and the coating should be uniform as far as possible, without local deposition, bubbles and adhesion. When used on wet or non-absorbent substrates, there is no need to hit the bottom layer.

6. The waterproof layer should extend from the ground to the wall, 250 mm.. On the ground. The height of the waterproof layer on the wall near the shower head in the bathroom should not be less than1800 mm. ..

7. When the first coating is cured and non-sticky, the second coating is waterproof according to the first material construction method. In order to make the film thickness uniform, the scraping direction must be perpendicular to the first scraping direction, the scraping amount is slightly less than the first scraping, and the thickness should be 0.5 mm

8, besmear brushs waterproof coating should be uniform, the general thickness shall not be less than 65438+/-0.5 mm, especially the facade construction, can add one or more layers. When adding non-woven fabrics, the lower coating and the upper coating should be constructed continuously, and the non-woven fabrics should be laid flat and brushed with a brush without leaving empty drums.

9. The waterproof surface of the coating film should be free from blistering, flowing, smooth and concave-convex, and the joint with pipe fittings, sanitary ware, floor drain and drain outlet should be tight, smooth and leak-proof.

10, the toilet waterproof construction scheme finally requires that the water must be closed 24 hours after the waterproof project is completed.
