How to do waterproofing in the bathroom? What waterproof material to use, find the steps.

Bathroom waterproofing, generally we will directly recommend the use of mortar waterproofing agent, not only with the base surface sticky firm, but also high puncture resistance can be with the same life as the building, the use of the method.

1.Clean the construction site and sprinkle water to make it fully moist but there should be no stagnant water.

2.Wall: The total thickness of the waterproof layer (waterproof mortar + waterproof mortar) is not less than 10 mm for the wall, not less than 20 mm for the ground, and not less than 1800 mm for height.

1) Mix "Lauyer mortar waterproofing agent" with cement at 1:3 to form a waterproof mortar, and paint it once or twice on the base surface, with a total thickness of 2 mm.

2) After 20 minutes, after the waterproof mortar is dry, stir it into a waterproof mortar with "Laoyal" and cement and sand according to 1:2:6, and wipe it on the surface of the waterproof plain ash with a thickness of 8 mm.

After the waterproof mortar layer is solidified, it is cured by sprinkling water.

First, we must do the leveling layer. First of all, the ground should be leveled with cement mortar (especially for rerenovated houses), and then waterproofing. This avoids the waterproofing coating leaking due to uneven thickness or puncture of the waterproofing membrane.

Second, we must do a good job in key parts. The joints between the wall and the floor, as well as the joints between the water and sewer pipes and the ground, are the most problematic areas. Therefore, these parts must be paid special attention to, and the treatment must be meticulous, without the slightest sloppiness.

Third, the wall should also be waterproof. In order to achieve a better waterproof effect, the wall of the general bathroom should also be waterproofed about 30cm high to prevent water from penetrating the wall. The wall adjacent to the bathtub should also be waterproofed at a higher height than the top edge of the bathtub.

Fourth, we must do waterproof experiments. After the waterproof construction is completed, all the sewers of the bathroom should be blocked, and a "low wall" should be built at the door of the bathroom for water injection test, and the water injection height should be about 20cm. After 24 hours, if there is no leakage on the walls and floors around the bathroom, it means that the waterproof quality of the bathroom is very good.

On the contrary, it is necessary to find out the leakage point and carry out repairs. At present, there are usually two types of home improvement waterproofing materials on the market: one is liquid waterproof coating, polyurethane waterproof coating and polymer composite waterproof coating; The other is powdered waterproof plugging materials, such as waterproof adhesive powder and plugging spirit.
