How to test the re tiling and waterproofing of kitchens and bathrooms

Before tiling, it is necessary to do paint waterproofing, and waterproof coatings such as HG203, JS, and K11 for kitchen are OK. After doing a good job, make a cement mortar protective layer on top of the waterproof layer, store water for 24 hours after drying, test the waterproof effect, and paste the brick without leakage.

Use the king who can plug the leakage, the golden soup water does not leak, Cao Yangbao, South Korea's Shuangxiong, Japan's Daguan, or JS, the root of the corner of the wall to do a radius of 1cm arc, the bottom of the pipe lane, the water flange, do ascending treatment, brush waterproof material, and then paint waterproof material on a large surface, brush twice and the direction is vertical; The dry area should be 300 high, the wet area should be 1800 high, and the water should be stored for 24 hours without leakage (the lowest part of the water storage shall not be less than 2cm), and then the wall and floor tiles should be paved.

For waterproofing in the bathroom, we generally recommend the use of mortar waterproofing agent, which is not only firm in adhesion to the base surface, but also has high puncture resistance and can have the same life as the building, and the key point is that the cost performance is also very good.

As for the inspection of waterproofing, it is necessary to do a closed water test.

Closed water test steps:

1. After the waterproof construction is completed, the closed water test can be done after 24 hours;

2. Temporarily block the floor drain and the perimeter of the pipeline mouth;

3. Build a 20CM high retaining wall at the door;

4. Start to store water, with a depth of 5-20 cm, and mark the water level;

5. Water storage time 48 72 hours;

6. After the water is closed on the first day, see if the water level has dropped significantly, if so, please check whether there is leakage around the roof and pipes downstairs in time, if not, continue to close the water;

7. On the third day, the water is closed, and the downstairs ceiling and roof pipes are fully inspected.

8. Carry out the next process after being fully qualified.
