How to do waterproofing to avoid worrying about the bathroom?

1. Try not to damage the original waterproof layer.

In the newly delivered high-rise building, the waterproof layer is usually made in accordance with the relevant standards, but in the process of decoration, some bathroom bathing equipment and a variety of water and water pipelines may be re-planned, and then the original waterproof layer of the building may be damaged. Qinglong Construction recommends that friends who need decoration should try not to damage the original waterproof layer, and if it is damaged, it must be repaired in time to avoid leakage in the future.

2. Re-paving floor tiles should be waterproof on the ground.

If you need to replace the original floor tiles in the bathroom, after chiseling off the original floor tiles, you must first level the ground with cement mortar, and then do waterproof treatment, so as to avoid leakage caused by uneven thickness of the waterproof coating.

3. The wall must be waterproof.

Water will splash on the nearby wall when bathing in the bathroom, and if you don't do waterproofing, the wall will be prone to mildew, so you must do a good job of waterproofing the wall before laying wall tiles. Qinglong construction suggests that the wall should not be less than 30 cm when waterproofing, and if the load-bearing light wall is right, the entire wall should be waterproofed.

4. The grooves of the water pipes in the wall should also be waterproof.

During the construction process, when pipes, floor drains, etc. pass through the floor slab, it is necessary to carefully construct the waterproof layer around the hole. Buried water pipes in the wall, so as to achieve reasonable planning, lay water pipes are all made larger than the diameter of the groove, the groove is plastered smoothly, and then the groove is brushed with polyurethane waterproof coating.

There are several steps:

1. Waterproof material selection : It is recommended to use K11 flexible waterproof coating in residential interior decoration.

2. Grassroots treatment

First of all, the base layer of the wall and floor should be cleaned up, and all the small gravel and raised small cement blocks should be cleaned up. Ensure that the surface is smooth and solid, no open water, no floating dust, no sand, no cracks, and no oil stains.

3. Paint the corners and corners

Use "no leakage" to paint the area around the root of the sewer pipe, the corner of the wall, and the floor drain twice to make a small arc to prevent leakage in the corners.

4. Stir the emulsion

Pour the emulsion into a bucket, add the powder slowly, and stir well with an electric mixer. Make sure that the stirring is uniform and free of lumps. (The mixing ratio is controlled according to the product instructions of each brand).

Suggestion: When stirring the emulsion, it is recommended to add an appropriate amount of 108 glue, which can improve the adhesion between the waterproof and the wall and ground. ）

5. Large-area painting

Wet the walls and floors with clean water before painting, and then paint a large area with a brush or roller. It should be painted in a criss-cross manner. Paint 2-3 times to ensure that the waterproof thickness of the wall is about and about and the waterproof thickness of the ground is about that.

Note: Brush should not be less than twice, but not too much, the waterproof brush is too thick, it is more brittle and easy to break. After the last waterproof brushing, dry for about 6 hours, touch it with your hands, do not stick your hands, do not dent for hard work, and you can carry out the next brushing.

Be sure to dry and brush the next time, some construction in order to save time, brush the second time if you don't dry, so waterproof, the quality will be greatly reduced.

6. Closed water test

After the waterproofing is done and the station is still for 24 hours, the closed water test can be done. The closed water test should be guaranteed to be not less than 24 hours, and the water line should be marked. After 24 hours, I went to observe whether the water level had dropped significantly, and then went downstairs to my neighbor's house to observe whether there was any leakage on the surface.

If there is no leakage, it is qualified. If there are signs of leakage, be sure to clean up the original waterproofing, and then redo the waterproof and closed water test.

7. Make a waterproof protective layer

After the closed water test is no problem, a protective layer is made of cement mortar on the waterproof surface. Some owners will find that my waterproofing is obviously very good, and the closed water test is also fine, why is it still leaking? There is a possibility that the waterproofing is no problem, and then the ground protection is not carried out, and the waterproof layer is accidentally damaged in the subsequent construction of the tiles, resulting in water leakage.

Therefore, it is very necessary to make a waterproof protective layer.
