What details do you need to pay attention to when doing bathroom waterproofing in hotel decoration?

Try not to destroy the original waterproof layer experience: the waterproof layer is easy to be destroyed when the ground is redecorated. If it is not repaired in time, it will leak water in the future and endanger the neighborhood. Therefore, attention should be paid to protecting the waterproof layer when decorating. If it is damaged carelessly, it should be repaired in time to avoid leaving hidden dangers. If you need to replace the original floor tiles in the bathroom, you must level the ground with cement mortar before waterproofing to avoid leakage of waterproof paint due to uneven thickness. Be sure to clean the ground before waterproofing and brush polyurethane waterproof coating for 2 to 3 times. Experience: the joints between the wall and the ground and the joints between the sewer and the ground are the most prone to problems. Workers must be urged to deal with these edges and corners, and waterproof coatings must be applied in place. The decoration team is required to do a good job of cement root protection for the upper and lower water pipes of the kitchen and bathroom, brush the polyurethane waterproof coating from the ground up to 20 cm, then redo the polyurethane waterproof on the ground, and add the original waterproof layer to form a composite waterproof layer to enhance the waterproof performance. Make sure the bathroom is waterproof. When taking a bath, water will splash on the adjacent wall. Without the protection of waterproof layer, the next wall and the opposite corner are easy to be damp and moldy. Therefore, the wall must be waterproof before paving the wall tiles. In general, the waterproof height of the wall is 30 cm, but the overall waterproof height of the non-load-bearing lightweight wall is at least1.8 m. Experience: The waterproof wall adjacent to the shower room should be 1.8m high. If a bathtub is used, the waterproof coating on the wall adjacent to the bathtub should be higher than the upper edge of the bathtub. Acceptance of waterproofing by 24-hour "water storage test" After the waterproofing project is completed, the door and drain shall be closed, the toilet floor shall be filled with water to a certain height and marked. If the liquid level does not drop significantly within 24 hours, especially if there is no leakage on the roof of the downstairs home, waterproofing will be qualified. If the acceptance is unqualified, the waterproof project must be redone as a whole before it can be re-accepted. Experience: In the acceptance of waterproof construction of light wall, water spraying test should be adopted, that is, water pipes should be continuously sprayed from top to bottom on the wall coated with waterproof paint for 3 minutes, and after 4 hours, it is observed whether there will be water seepage on the other side of the wall. If there is no leakage, it can be considered that the waterproof construction of the wall is qualified. * * * * The essence of this version of Chaozhai Forum can help you very well. ->
