Before the delivery of the new house, the floors of the living room, bathroom and kitchen have waterproof layers, but they are easy to be damaged when redecorating the floor. Therefore, when the new house is renovated, it is necessary to re-do the waterproof project. Waterproofing project is a very important link in the whole decoration process. This process is not a formality, not a show, but the first time to find problems, solve problems, and prevent problems before they happen. Once the problem is found, it must be repaired in time, otherwise it will leak water in the future and affect neighborhood relations. Let's analyze which places should be waterproof when decorating a new house.

1. Re-paving floor tiles: When the kitchen and bathroom floor are decorated, the waterproof layer is most likely to be destroyed. When specialization, try to protect the original waterproof layer. Once damaged, it should be repaired in time and the waterproof layer should be made again. When replacing the floor tile, the original floor tile should be leveled with cement mortar, and the mortar should be evenly coated with waterproof coating on the wet base surface with a brush, scraper or roller to prevent leakage and sand holes, and then the second layer should be coated after the first layer is dry. During construction, pay attention to the intermittent mixing of mud to prevent precipitation, and the mixed mud should be used up within 20-40 minutes. In this way, the waterproof project of the kitchen and bathroom is completed.

2. Walls adjacent to the bathing equipment: When the washbasin and sink are used, water will splash on the adjacent walls. If there is no waterproof protection, the wall is easy to be damp and moldy. Therefore, before laying the front tiles, the wall must be waterproof, but the light wall that is not heavy should be at least 1.8 meters high, and it is best to waterproof the whole wall. The waterproof wall adjacent to the shower position should also be 1.8m high, and the waterproof paint on the wall adjacent to the bathtub should be higher than the upper edge of the bathtub.

3. Wall with embedded water pipes: When the water pipes are buried in the wall, grooves larger than the pipes should be made and smoothed, and then waterproof coatings should be brushed in the grooves for waterproof treatment.

4. Sewage outlet and floor drain: The floor of kitchen and bathroom must be inclined to the floor drain to ensure smooth drainage and no water accumulation. Try to avoid changing the original position of drainage pipes and floor drains during decoration.

5. Joints between the wall and the ground, and between the upper and lower water pipes and the ground: leakage mostly occurs at the pipe root, floor drain, sanitary ware and yin and yang corners that pass through the floor. The reason is that the pipe root, floor drain and other parts are loose, the bonding is not firm, the coating is not tight or the waterproof layer is partially damaged, and the length of the parts is not enough. These edges and corners are the most prone to leakage, so attention should be paid to the construction of detailed joints in weak parts, and waterproof coatings must be applied in place. When pipes, floor drains, etc. When crossing the floor, the waterproof layer around the hole must be carefully constructed. The upper and lower water pipes are protected by cement, and the waterproof coating 10 ~ 20cm is applied upward from the ground, and then the waterproof layer is made on the ground to form a composite waterproof layer to enhance the waterproof performance.
