Causes of moldy wallpaper:
First of all, the reason why most wallpaper is moldy is not the wallpaper itself, but the wall. Many walls are of poor quality and easy to seep, while PVC wallpaper has poor air permeability. The wallpaper glue is organic matter such as glutinous rice flour, which is easy to get moldy. A good way to solve this kind of problem is to choose a good moisture-proof wallpaper basement membrane.
There is another reason for mildew, which we can easily ignore. In wallpaper construction, if the glue is not completely dried, there will be hall wind or large temperature difference between indoor and outdoor, which will easily lead to curling and bulging of the wallpaper, and mildew will occur in the future due to the long-term existence of moisture and air in the wallpaper.
In addition, if it rains heavily in summer, the ambient humidity will easily make the wallpaper moldy.

Treatment of moldy wallpaper;
First of all, if the moldy area of wallpaper is large or a lot, you think it will be ugly even if it is repaired. If you want to change your style, just replace it.
If the wallpaper is not moldy, it means that the quality of your wallpaper is not bad, and there is still time to remedy it. First of all, it is recommended to wipe with soapy water or detergent. If not, wipe it with a cloth soaked in disinfectant alcohol. If it's not too serious, you can remove the mold by rubbing it two or three times.
Another way to remove mold is to use bleach. But it is easy to irritate the skin, so be sure to wear rubber gloves when using it, and use too clear water. Some people may worry that without bleach, the original color will be removed. Then use some special mildew remover to treat the mildew spots on the wall. You can ask at the wallpaper shop.
How to prevent wallpaper from moldy?
1, select breathable material.
At present, there are many wallpaper materials on the market, including non-woven fabrics, wood fibers, PVC, glass fiber substrates, cloth covers and so on. Relatively speaking, PVC wallpaper is the most airtight, and it is the easiest to intercept the water vapor discharged from the wall. It is easy to get moldy after a long time.
2, keep the wall dry
Walls must be kept dry, and new cement construction generally takes 20 to 40 days to spread wallpaper. It is worth noting that when decorating, attention should be paid not to let irregular construction mix into the sea sand that is not suitable for wall painting. Sea sand is high in salt content and easy to absorb water, which has buried a "flood" for the later wall.
Before pasting wallpaper, you need to deal with the base surface first. If it is a second-hand house decoration, the gap in the wall must be filled in, otherwise the wallpaper will be easy to empty.
3, pay attention to the quality of the shop is stuck
Three-point material and seven-point project can achieve better results by paying attention to small details when wallpaper is on the wall. Wallpapers generally have various patterns. When paving, be sure to pay attention to whether there is a big gap between the two wallpapers and whether the mosaic is aligned. In addition, when paving, watering will wet the wallpaper, and it will shrink after thorough drying, so be sure to leave a good expansion position. Try not to open the contraction joint of the wall to the windward mouth.
4, adhere to the use and maintenance
Proper maintenance can prolong the life of wallpaper and enhance its moisture-proof function. Do not completely open doors and windows during construction and within 24 hours after completion of construction. Excessive ventilation will lead to rapid drying of wallpaper, and cracks will occur at the joints after uneven shrinkage. After paving for 3 days, pay attention to adjust the ventilation. Open doors and windows during the day to keep ventilation; Close the doors and windows at night to prevent moisture from entering, thus affecting the firmness of pasting.
