4 strokes to solve wallpaper mold problems

In fact, the reason that the majority of the wallpaper is moldy is not in the wallpaper itself but in the quality of the wall structure. Due to the poor quality of the wall, water seepage problems are prone to occur. If the material of the wallpaper with poor air permeability is selected, there will be a considerable chance of moldy spots. In addition, if the glue is not completely dried during the process of applying the wallpaper, it is easy to change sharply due to the temperature difference, which causes the situation of bulging and kicking of the drum. In the future, moisture and moisture will be deposited, and it will turn into a moldy head. How to prevent it? Here are four tips to help you keep your wallpaper away from you!

1, select the breathable material

As the saying goes: “Three points of material and seven divisions of work”, no matter how good the quality of the material is, the quality of construction is also a loss. When paving, besides paying attention to the alignment of the mosaic, it is also necessary to accurately grasp the reserved width of the contraction joint, and to avoid opening the contraction joint directly to the upwind mouth.

4, proper maintenance

After completion, it is necessary to pay attention to adjust ventilation to prevent moisture from entering the firmness of the adhesive.
