Many families in the bathroom in the second renovation, like to knock out the original bathroom wall tiles, laying new tiles. This will require a new waterproof project on the bathroom floor. If there is a quality problem in the waterproof works, the water stains will hit the next room, and if it is heavy, it will leak downstairs, causing serious damage to the home and the neighborhood. There are several precautions for the secondary renovation of the bathroom:

First, ground treatment
If you want to replace the floor tiles of the bathroom, you should level the floor with cement mortar after you cut away the original floor tiles, and then do a waterproof treatment. This will prevent leakage of the waterproof coating due to uneven thickness. The seams should be brushed into place. The seams between the bathroom wall and the seams between the upper and lower water pipes and the ground are the most prone to problems. When you are in construction, you must urge the workers to handle these corners, so waterproof paint must be applied in place.
Second, the bathroom floor tiles should use non-slip texture. General matt surface or shallow convex floor tiles can play a very good anti-slip effect. The floor of the bathroom should be 10-20 mm below the floor of other rooms. Consider the position and size of floor drain when laying tiles. Usually, the laying of bricks retains a slope of 1% water leakage, and the floor drain is the lowest for drainage. Tile seams should be the same thickness and alignment with the wall tiles.
Second, wall treatment
In the general bathroom water repellent treatment, about 30 cm of waterproof paint is also applied on the wall to prevent water stagnating through the wall. However, if the bathroom wall is a non-load-bearing light wall, the entire wall should be painted with waterproof paint. If your home uses two-seater shower screens, the associated two walls should also be painted. If your home uses a bathtub, the height of the waterproof coating should be higher than the upper edge of the bathtub.
Wall tiles should be full. Tiles can resist the erosion of moisture, protect the waterproof layer of the walls, and at the same time, they are easy to maintain clean and beautiful for a long time. Households using ceilings should pay attention to the part covered by the ceiling and also be covered with tiles in order to protect the entire wall.
Third, dry and wet separation
"Dry and wet partitions" are the current popular foreign design ideas, namely the separation of the shower area from the toilet seat and the wash basin area. A brand tile designer said: "Dry and wet areas can be divided by using different materials and colors of the tiles, so that the two do not interfere with each other, to avoid the kind of splashes in the past, after bathing East wipe the West rub. â€
Fourth, waterproof experiment must be done
After the renovation of the bathroom was completed, all the toilets in the bathroom were blocked, and a 25 cm high “can†was built at the entrance. Then, 20 cm of water was poured into the bathroom. After 24 hours, you can check whether there is any leakage around the wall and the ground. This 24-hour waterproof test is the key to ensuring the quality of the bathroom waterproofing project. You must do it.
Fifth, keep the water open
All sewers in the bathroom, including floor drains and plumbing fixtures, should be kept open. In this way, we can fundamentally avoid the occurrence of the "flooded seven army" tragedy.
