How is the home waterproof?

In home decoration, the places that need waterproofing are usually bathrooms, kitchens, balconies and basements. Although not every family has a basement, if it does, it must be waterproof. I think everyone should know the importance of waterproofing.

Step 1: Before waterproof construction, the grass-roots treatment must be smooth, firm and dry without sharp corners, oil stains and dust.

Step 2, node protection: firstly, it is necessary to coat flexible pipeline treatment agent on the pipeline node to seal it, and then coat rigid plugging plug to make it into a 45-degree slope or arc; The second is the angle of yin and yang, and the corner of the wall root is also made into a slope of 45 or an arc. After that, the additional layer of the joint should be strengthened, that is, the joint at the internal corner of the pipe or wall root should be coated with waterproof coating first, and the internal corner of the pipe or wall root should be coated with 20cm-30cm. Because most of the water leakage problems in life occur in these humble nodes, we must do a good job in node protection.

Step 3: When the waterproof coating is applied to the wall and ground in a large area, it should be applied for 2-3 times. The total thickness depends on the material, which is generally1.5 mm. The painting direction should be consistent every time, and the painting direction should be perpendicular to the previous one. The next construction can only be carried out after the first work is completed. Brush the wall first and then the floor, and the coating should be even and flat. The waterproof height of the wall should be treated according to different places. For the bathroom, the waterproof height of the shower area wall is generally above 180cm, the dry area should be above 30cm, and the waterproof height of the wall with water distribution point should be above 120cm.

The fourth step, the closed water experiment, the last waterproof decoration is completed, and after it is completed, the closed water experiment is done. First block the floor drain, the waterline of the grounding point should not be less than 2cm, and store water for at least 24 hours (there is also a 48-hour closed water experiment, which is safer) to check whether the waterproof is qualified. You can observe the water level and whether there is leakage on the corresponding floors and pipes downstairs. If there is leakage, it needs to be redone, and it must not be neglected.

Step 5, conduct the second water closing experiment. After the water closing experiment is qualified, check the waterproof height, film thickness and smoothness, and then make a 2-3cm thick cement mortar protective layer to protect the waterproof layer. After the protective layer is completed and completely dried, conduct the second water closing test according to the standard. The inspection standard is the same as the first closed water experiment.

Step 6: After the acceptance of the second closed water test, you can sign to confirm the waterproof acceptance of the decoration.
