1. Brush the first time waterproof coating. Ensure that the construction site is clean and dry before construction, and the waterproof coating should be covered without any omission. It is firmly bonded to the base layer, free from cracks, no bubbles, and no falling off. The brushing height is consistent and the thickness is required to meet the product requirements.
2. Brush the second time waterproof coating. Note that there is a certain time interval between the first and second passes of the waterproof coating. The second pass can be carried out after the first pass of the paint is dry, depending on the coating. The interval is too short and the waterproof effect will be greatly reduced.
3. Spread the protective layer. In order to prevent the subsequent construction from damaging the waterproof layer, it is necessary to apply a protective layer on the surface of the waterproof coating. The protective layer should completely cover the waterproof layer, and there is no leakage. It is firmly bonded to the base layer, free from cracks, no bubbles, and no falling off.
4. Closed water test. In the closed water test, the water at the highest point on the ground shall not be less than 2 cm, and it shall be stored for at least 24 hours, and it shall be qualified after observing no leakage. If there is leakage, you need to redo it, and you should not neglect it.

1. The elevation of the kitchen and bathroom should be checked correctly, paying special attention to the correct position of the floor drain.
2. The quality of the floor drain and the root wall of the pipeline should be carefully checked. The wall hole should be compact and qualified. The root of the pipeline must be caulked as required during the screed construction.
3, the yin and yang angle should be made into a circular arc shape, and straight, flat light.
4, screed construction: the base surface has voids, cracks, unequal defects, repaired with cement mortar. The base surface must be firm, smooth, clean, free of dust, greasy, wax, mold release agents, and other debris.
5. After the leveling layer is dry, the waterproof layer can be constructed. It should be fireproof and waterproof during construction. Construction workers should wear soft-soled shoes.
6. After the waterproof layer is completed, the finished product protection shall be carried out, and no businessman shall walk. After passing the inspection and confirming the qualification, the concealed project acceptance visa can only be processed before the next process can be carried out.
7. After the waterproof construction is completed, the water storage test is carried out, and no leakage after 24 hours or more is regarded as qualified. Perform a secondary water storage test after the equipment is installed.
