1. Use cement mortar on the ground to find a slope toward the floor drain, but the surface should be flat. The slope near the door is small, and the slope near the floor drain is large.
2. The pipeline passes through the root of the floor and near the floor drain to enhance waterproofing. The root of the pipe should be tightly sealed with building sealant, and after the cement is smoothed to protect the feet, when the waterproof paint is applied, one or two layers of glass cloth reinforcement should be pasted.
3. The wall surface is clean and flat without floating dust and small particles, and the junction of the wall and the ground is wiped with a small original angle or slope angle. When painting waterproof paint, paste 1~2 layers of glass cloth reinforcement layer.
4. The total thickness of polyurethane waterproof coating is required to be more than 1.5 mm. It cannot be determined by the number of passes. Brush the tube root and wall corner reinforcing layer first, and then brush and scrape a large area after the surface is dry at room temperature for 4 hours. There must be no missing scraping or bubbling. After 24 hours of curing on a large area, apply the next layer.
5. First paint the facade and then paint the plane, and the direction of the next painting is perpendicular to the previous one. When the coating film is semi-cured for the last time, throw the coarse sand to facilitate the combination with cement mortar in the future.
6. The ground waterproof layer should be painted to a width of 300mm outside the bathroom door. Waterproof ground The waterproof layer should be 200mm above the ground.
7. Do a 36-hour closed water test according to the requirements of the waterproof specification.
Specifications for bathroom waterproof decoration acceptance:
1. Acceptance one by one: a closed water test will be carried out during the general bathroom decoration process. But after the completion of the project, the acceptance cannot be ignored, and all toilets must be checked and accepted one by one.
2. Inspection after the construction process: each process before the construction of the bathroom waterproof layer (base-level treatment, hole cleaning and plugging, leveling layer construction, filling and sealing ointment, additional layer of details, etc.) After checking the records, the construction of the next process can be carried out.
3. Acceptance after waterproofing of the bathroom: each time the waterproofing layer is painted, and the next waterproofing layer can be applied only after the supervision engineer checks and confirms that it meets the requirements.
4. After the waterproof layer is painted and dried, it needs to be checked and accepted: after the waterproof layer is painted and dried, the quality of the waterproof layer should be carefully inspected and accepted. The inspection content includes whether the waterproof layer is fully coated, whether the thickness is uniform, whether the seal is tight, and whether the thickness reaches the design. Requirements (section sampling), the surface has no defects such as drumming, cracking, and warping. The closed water test can only be carried out after the joint inspection and acceptance of Party A and the supervision engineer.
5. Bathroom waterproof and closed water test: The waterproof layer must be subjected to a closed water test, and the test time is not less than 24 hours. There must be no water seepage or wetting under the floor, around the pipes and other corners of the wall. Only after Party A and the supervisory engineer have passed the joint inspection and acceptance and handled the concealed acceptance record can the construction of the waterproof protective layer in the next process be started.
6. Waterproof acceptance after the decoration is completed: after the construction of the waterproof coating film protective layer of the bathroom is completed, the cushion construction can only be carried out after the professional plumbing pipes are laid and passed the acceptance. During the process handover process, the equipment and civil engineering should be closely related Cooperate.
7. Second water closing test: After the bathroom floor surface decoration is completed, the second water closing test should be carried out. The water closing time should not be less than 24 hours. Leakage and no wetting phenomenon are qualified, and at the same time fill in the closed water inspection record and carry out waterproof construction acceptance according to the procedure.
