Selection of Environmentally Friendly Polyurethane Coatings

发表时间:2022-07-15 访问量:1492

The waterproof material should be a one-component environmentally friendly polyurethane coating, which is currently the waterproof material recommended by the Ministry of Construction. Since the paint can tightly wrap the pipeline and the ground, penetrate into the gap, and will not shrink after drying, it is more suitable for small-area houses with more pipelines and gaps than rigid materials such as waterproof cement. Brand coatings should be selected when purchasing such coatings, and the material cost per square meter is also very reasonable. At present, many domestic polyurethane coating manufacturers have their own construction teams. When purchasing coatings, manufacturers are required to provide professionals.

In order to make the waterproof period longer in the future, the paint generally needs to be brushed 3 times. In order to let the paint fully dry, it is not possible to choose to do it in rainy or humid climates. Generally, the dry-through period of one-component environmentally friendly polyurethane coatings is about 3 to 4 days.

Counting the one-component environmentally friendly polyurethane coating, the cement layer covering the coating and the tiles, the materials used per square meter generally do not exceed 400 yuan. In this way, for a bathroom with a size of 5 square meters, it will cost about 2,000 yuan to re-do the waterproofing, and the bathroom facilities such as bathtubs that need to be reconfigured will be counted separately.

After the waterproof construction is completed, all the sewers in the bathroom should be blocked, and a "low wall" should be built at the entrance of the bathroom to conduct a water injection test, and the water injection height should be about 20cm. Check after 24 hours. If there is no leakage on the surrounding walls and ground of the bathroom, the waterproof quality of the bathroom is very good. On the contrary, it is necessary to find the leak and repair it.

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