What is the best waterproof material for the bathroom?

Generally speaking, the materials should be strictly controlled, which can greatly avoid workers from buying fake materials to shoddy and cutting corners.

General bathroom waterproofing, it is recommended to use mortar waterproofing agent, simple construction, high strength, puncture resistance cost performance is also very high, is now a more commonly used material in home decoration.

2. Precautions for waterproofing in the bathroom.

As for the precautions, it is necessary to pay attention to the thickness and height of the coating during the construction of the worker, whether the coating is uniform, whether the closed water test is done in time, and so on.

3. How much does it cost to make a bathroom waterproof?

1. If you want to determine the price of bathroom waterproofing, you must first determine what kind of waterproof material to use, generally we will directly recommend the use of mortar waterproofing agent, which is not only firm with the base surface, but also has high puncture resistance, and the waterproof life can be the same as the life of the building, and the key point is that the cost performance is also very good.

2. The price per square involves the brand and dosage of the product, different brands, the sales price and dosage are slightly different, taking the Hengjian Bojing brand as an example, 20KG of mortar waterproofing agent, the ground can be made about 5 square meters or the wall can be made about 10 square meters. As for the price, it is recommended to go to the local building materials market to find out.

3. The price per square meter is also related to the local wage rate, and the wage price in the first-tier developed areas is definitely higher than that in the second- and third-tier cities.

JS does the problem of waterproofing and leakage repair in the bathroom.

High-performance mortar waterproofing agent, two-component polymer modified cement-based waterproofing mortar (K11 general-purpose type), two-component polymer modified cement-based waterproof coating (K11 flexible type), floor wall solid, super waterproof (composite dual-purpose) and so on. When doing bathroom waterproofing, we should pay more attention to:

1. Ground treatment.

Be sure to level the ground before applying waterproofing. Screed construction method: if there are voids, cracks and unequal defects on the base surface, repair and smooth with cement mortar.

The base surface must be firm, flat, clean, free of dust, greasy, wax, release agent, etc., and other debris substances. The construction of the waterproof layer can only be carried out after the screed is dry, and the construction should be fireproof and waterproof during the construction. After the waterproof layer is completed, the finished product should be protected, and no one should walk around.

2. Wall treatment.

About 300mm high waterproof paint should be used for wall treatment to prevent water from penetrating the wall and returning moisture.

The painting height between the wall and the floor (plane and façade) of the bathroom should be greater than 100mm.

If there is a shower in the bathroom, the waterproof height of the room is not less than 1800mm.

If there is a bathtub, the waterproof height of the wall adjacent to the bathtub should be 300mm higher than the bathtub.

The waterproof height of the bathtub is not less than 800mm.

The waterproof height of the squatting pit should exceed the ground of the squatting platform by 400mm.

For the light wall of the bathroom renovation and the self-built light wall, it is recommended that the waterproof height should be at the top.

3. Do a closed water test.

After the waterproofing construction is completed, the water storage test is carried out. Block all the drains in the bathroom, build a water barrier about 200mm high at the door, and then pour about 20mm 30mm deep water into the bathroom, and check whether there is leakage on the surrounding walls and the ground after 24 hours, the waterproof experiment is the key to ensure the quality of the bathroom waterproof project, and it must be done. If there is no leakage after more than 24 hours, it is considered qualified.

If water leakage is found, the water storage test should be stopped immediately, the waterproof layer should be re-improved, and the water storage test should be carried out after the treatment is qualified.

The toilet is generally small in area and complex in base (there are detailed locations such as pipe roots, wall pipes, and wall casings), so it is first recommended to use paint products.

Secondly, the two most used materials in waterproof coatings: one polymer cement waterproof coating (usually said JS waterproof coating) and the other is polyurethane waterproof coating. Among the two materials, the polyurethane coating material has better performance, but there are generally volatile solvents in the material, so there is a pungent odor; JS waterproof coating is a water-based coating, basically no odor after construction, but the material performance is worse than polyurethane, but the waterproof effect is no problem.

Again, it is necessary to choose big brand products, don't be greedy, recommend: rainbow waterproof, panther waterproof products.
