How to check and accept bathroom waterproofing
Bathroom waterproofing is a crucial part of home decoration. Once the waterproofing is not in place, problems such as water seepage and mold may easily occur in the future, affecting the living experience. So, how to check and accept the bathroom waterproofing construction after it is completed? The following are detailed acceptance steps and precautions to help you ensure the quality of your waterproofing project.
1. Preparations before bathroom waterproofing acceptance
1.Check waterproofing materials: Ensure that the waterproof coating or membrane used meets national standards, and check the product certificate and test report.
2.Observe grassroots processing: Before waterproofing construction, the base layer should be smooth, clean, and free of cracks, and the yin and yang corners should be made into arc shapes.
3.Confirm construction technology: The waterproof layer should be applied evenly without leakage or bubbling. Generally, it needs to be applied 2-3 times.
2. Specific steps for bathroom waterproofing acceptance
| Acceptance items | How to operate | Qualification standards |
|---|---|---|
| closed water test | Store water on the bathroom floor, with the water level no less than 2cm, and keep it for 24-48 hours | The water level has not dropped significantly, and there are no signs of water seepage downstairs or in adjacent rooms. |
| Wall water spray test | Spray the wall with a water hose continuously for 30 minutes | There is no water seepage or moisture on the other side of the wall |
| Seam inspection | Focus on checking joints such as floor drains, pipe roots, threshold stones, etc. | No cracking or peeling, and the waterproof layer is completely covered |
3. Common problems and solutions
1.Water closure test failed: If the water level drops or water seepage occurs downstairs, you need to identify the leak point, re-patch the waterproof layer and test again.
2.Dampness on the wall: It may be that the waterproof layer has not been painted to the specified height (recommended 1.8 meters for shower areas and 0.3 meters for other areas) and needs to be repainted.
3.Root leakage: The pipe root should be treated with an additional layer. If water seepage is found, it must be sealed with a leak-stopper and re-painted with waterproof coating.
4. Precautions for acceptance
1.Time selection: The closed water test should be carried out after the waterproof layer is completely dry (usually 48 hours is required).
2.Full supervision: It is recommended that the owner personally participate in the acceptance inspection or entrust professional supervisors to inspect.
3.Keep records: Take photos or videos to record the acceptance process as a basis for later rights protection.
5. Follow-up work after waterproof acceptance
1.Protective waterproof layer: After passing the inspection, avoid damaging the waterproof layer when laying tiles or installing facilities.
2.Regular inspection: After moving in, regularly observe corners, floor drains and other water-prone areas, and deal with problems promptly if problems are found.
Through the above steps, you can comprehensively check the quality of the bathroom waterproofing project and ensure that you will have no worries in future use. If you have any doubts about the acceptance results, it is recommended to contact a professional waterproofing company for re-inspection.
