Bathroom waterproof knowledge

Bathroom waterproofing is a key waterproof location, and frequent contact with flowing water, and drainage pipes, floor drains, yin and yang angles, to do a good job of bathroom waterproofing, we must deal with these details in order to ensure the waterproof quality.

1, brush waterproof layer

The bathroom is the key point of the family's waterproofing. It must be waterproofed during the renovation. Take the polymer cement-based waterproof coating as an example. Leibangshi has a universal GS waterproof coating and a flexible JS waterproof coating. The coating is brushed twice. Before and after the vertical cross, single thickness of 0.8mm ~ 1mm, the thickness of two layers does not exceed 2mm.

2, Yin Yang angle, the seam between the upper and lower water pipes and the ground

Leakage mostly occurs in the pipe roots, floor drains, sanitary ware, and yin and yang corners that pass through the floor. The reason is that the roots, floor drains and other parts are loose, the bonding is not strong, the brushing is not tight, or the waterproof layer is partially damaged, and parts are lapped. The length is not enough. These corners are the most prone to leakage. Pay attention to the details of the construction, waterproof coating must be brushed into place. When pipelines and floor drains cross the floor, the waterproof layer around the holes must be carefully constructed. The upper and lower pipes must be cement screed, and 10-20 cm of polyurethane waterproof coating should be brushed upward from the floor, and then the polyurethane waterproof layer should be used on the ground. , Plus the original waterproof layer, composed of a composite waterproof layer to enhance the waterproof performance.

3, the wall adjacent to the bathing facilities

When the wash basin is in use, the water splashes and wets the wall. If there is no waterproof layer, the wall will be easy to get wet. If the water vapor accumulates for a long time, it will erode the wall and even penetrate the wall. Therefore, before laying the wall tiles, be sure to Make a good waterproof treatment on the wall. The wall of the wash basin should be at least 30cm high. The water wall opposite the shower should be at least 1.8 meters high. The best wall is waterproof, and the wall adjacent to the bathtub is good. The height of the waterproof coating should also be higher than the top edge of the bathtub.

4, sewage outfall and floor drain

The floor of the kitchen and toilet must be leaked on the slope to make the drainage smooth. No water should accumulate. During the renovation, the original drainage and sewer pipes and floor drain locations should be avoided.

5, buried water wall

Buried in the wall, the pipe should be larger than the diameter of the groove, smooth plaster in the groove, and then coated with polymer cement-based waterproof coating in the groove for waterproofing.
