What is the cause of wall blistering?
Bubbles on the wall are caused by the collocation of wall substrates and improper waterproof treatment of the wall. The wall base that is easy to produce bubbles is generally composed of gypsum powder, talcum powder and Shuangfei powder. Once this combination encounters moisture, it is easy to expand, leading to bubbles on the wall.
Bubbles on the wall are also due to the inadequate waterproof treatment of the wall, which leads to water entering the wall through cracks and destroying the paint film on the wall. The pressure generated by the outward diffusion of water in the wall expands the paint film, thus generating bubbles on the wall.
Methods of eliminating bubbles on wall surface
If the bubbles on the wall are small or local, consumers only need to remove the blistered area, then smooth the edge of the removed part and apply primer.
If the wall bubbles in a large area, it is necessary to understand the reasons for the foaming of the wall. If the bubble on the wall is caused by the collocation of the base materials, consumers should remove the base materials together, and then re-select the base materials to paint the wall after the wall is dry.
In daily life, we should also pay attention to the maintenance of the wall, whether domestic water enters the wall, whether the wall water pipe leaks, and avoid bubbles in the wall.
Solutions to bubbles on indoor walls
1, strict construction standards and construction sequence are the first step to prevent wall foaming, because indoor walls are generally in the shade, so it is impossible to 100% dry. If necessary, waterproofing should be carried out locally.
2. If the wall is blistered, the putty must be completely removed for the first time, and then the putty and paint coating should be brushed again. When you need to see it, look at the root of the wall
3. In addition to construction reasons, some bubbles on the wall are caused by bad usage habits or broken pipes. Therefore, it is particularly important to develop good water habits, followed by daily maintenance and maintenance of household pipelines.
4. Although the rainy season construction is not a taboo for decoration, it is easier to soak in front of the construction at this time, so it is suggested to stop the decoration activities in the rainy season.
5. If the bubbles on the wall surface caused by foundation, pipeline and other reasons are not large, local bubbles can be removed, polished smoothly and repainted with primer and coating; If there is a large area, it is necessary to make a whole piece of putty, and it is best to wait until the wall is completely dry before construction.
