How to do the waterproof construction of the kitchen bathroom

1. Kitchen and bathroom floor.

When renovating the kitchen and bathroom floor, the waterproofing layer is the most easily damaged. Therefore, when rebuilding, we should try to protect the original waterproof layer, and once damaged, we should repair it in time and redo the waterproof layer.

Second, it is adjacent to the wall with the bathroom equipment.

You must know that when we usually wash, water will splash on the adjacent wall, if there is no waterproof protection, the wall is prone to dampness and mildew. Therefore, before laying the front tiles, be sure to do a good job of waterproofing the wall. Non-heavy and lightweight walls, at least to be meters high, preferably the entire wall waterproof.

The waterproofing of the wall adjacent to the shower location should also be at the same height, and the height of the wall waterproofing coating adjacent to the bathtub should also be higher than the upper edge of the bathtub.

3. The joints between the wall and the ground, the water pipes and the ground.

Everyone should know that leakage generally occurs in the pipe roots, floor drains, sanitary ware and yin and yang corners that pass through the floor, which is caused by loose pipe roots, floor drains and other parts, poor bonding, poor painting or local damage to the waterproof layer, and these edges and corners are the most prone to leakage, so the joints between the wall and the ground, the upper and lower water pipes and the ground should also be waterproof.

Fourth, the wall of the buried water pipe.

When burying the water pipe in the wall, it should be made a groove larger than the pipe warp, and the plastering in the groove should be smooth, and then the waterproof paint should be brushed in the groove for waterproof treatment.

5. Sewage outlets and floor drains.

The floor of the kitchen and bathroom must be sloped to the floor drain opening, so that the drainage is smooth and there will be no water accumulation. At this time, the waterproof material of the bathroom is particularly important, and we should try to avoid changing the original drainage and sewage pipes and floor drain locations when decorating.
