One of the most common problems is wall-wracking, especially in the spring of each year. Wall-wracking is an annoying thing that will not only cause mildew on the walls but will also adversely affect the health of occupants. Then how to do it? The following Xiao Bian will share with you the reasons and solutions for the wall to return to the tide and give everyone a reference!
Causes of Wall Fade
Moisture on the wall is one of the most common problems. There are two reasons for this. One is because the indoor humidity is too high, and the southerly wind is a kind of dampening phenomenon. When the moisture in the air is too high concentration on the surface of a cold object, such as a wall paint, condensation phenomenon may occur and water droplets may be generated. When water vapor adheres to and infiltrates the surface of the wall paint film for a long period of time, it is easy to induce mold appearance on the paint film surface. Another reason is the internal cause, such as the quality of the wall paint, but it is closed: it is the paint product itself caused by poor antibacterial and mildew resistance. Because of the poor mold resistance of the product, water vapour can easily penetrate into the walls, causing the mold to grow easily. Improper operation of the wall painting process can also easily cause the paint film to be susceptible to mildew in the southern part of the country.
What to do if the wall is wet
In order to prevent wall dampening, we must first control from the source. Currently there are many decorative materials on the market, the most common are non-woven fabrics, wood fiber, PVC, glass fiber substrate, cloth surface, etc., relatively speaking, PVC material wallpaper is the most airtight, the easiest The water vapor emitted from the wall is boring and it is easy to form mildew after a long time.
What to do if the wall is wet
Sometimes the wall surface is caused by improper construction due to improper construction. Therefore, everyone should keep the wall dry during construction. After the cement is applied on the wall, it should be maintained for 20 days to 40 days before the wallpaper can be applied. It is worth noting that during the renovation, care should be taken not to allow irregular construction to mix sea sand that is not suitable for wall painting. Sea sand is high in salt content, and it is easy to absorb moisture. It is buried in the water for the later period.
How to do three walls
After the wallpaper is laid, everyone should pay attention to maintenance and proper maintenance. This will not only extend the service period, but also effectively prevent the wall from returning moisture. Do not open the windows and doors during construction and within 24 hours after construction. Ventilation over the General Assembly cause the wallpaper to drastically dry and shrink, resulting in cracking at the joints. After 3 days of paving, pay attention to adjust the ventilation.
These are the reasons for Xiao Bian's question about how to do wall-wrack and how to do it, and how to solve it. Let's give you a reference! When we encounter the southerly weather, we should close the doors and windows to prevent moisture and moisture.
