What is the cause of wall blistering?

Some newly renovated houses, not long after living in, will have white bubbles near the skirting line of the wall, so what is the reason for the bubbles on the wall? Besides the blisters on the wall, what else can be done to solve the blisters on the wall? What is the solution to air bubbles on indoor walls? Let me show you! The causes of wall blistering are the matching problem of wall foundation and improper waterproof treatment of wall surface. The wall base that is easy to generate bubbles is composed of gypsum powder, talcum powder and Shuangfei powder. Once it encounters moisture, it is easy to expand, resulting in bubbles on the wall. The moisture on the sticker enters the wall through cracks and destroys the wall coating. The pressure generated by the outward diffusion of water in the wall expands and bubbles are generated on the wall. This solution is based on the formation of bubbles on the wall. If the wall is blistered in a small area or partially, consumers only need to remove the blistering place, then smooth some walls, and then apply base oil on the walls. If the wall surface bubbles in a large area, it is necessary to know the cause of the wall surface foaming. If it is the matching problem of the base material, then the consumer will remove the base material together, and then choose the basic material to paint the wall after the wall is dry. In daily life, we should also pay attention to the maintenance of the wall, pay attention to whether the domestic water enters the wall, whether the wall water pipe leaks, and avoid bubbles on the wall. Solution of indoor wall bubble 1. Strict construction standards and construction sequence are the first step to prevent wall foaming. Because most indoor walls are located in the shade, it is impossible to achieve 100% complete dryness. When necessary, carry out local waterproof treatment. 2, metope blister must be eradicated for the first time, the first time be bored with child, and then brush putty and paint. When inspection is needed, the local government decides to start with the wall. 3. In addition to construction reasons, some of them are caused by bad habits or pipeline damage. 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 decoration taboo, but at this time the construction is easier to soak in the front. Therefore, it is suggested to stop the renovation activities in the rainy season. 5. If the wall surface bubbles due to other reasons such as foundation and pipeline, and the area is small, it can be dynamically cleaned to remove local bubbles, polished smoothly, and repainted with primer and paint; If it is a large area, the whole wall needs plastering, and it is best to wait until the wall is completely dry before construction.
