Reasons for moldy wallpaper:

First of all, most of the moldy wallpaper is not the wallpaper itself, but the wall. Many walls are of poor quality and prone to water seepage, while PVC wallpaper has poor air permeability, and wallpaper glue is organic matter such as glutinous rice flour, so it is prone to mildew. A good way to solve this kind of problem is to choose a good moisture-proof wallpaper basement membrane.

There is another reason that we easily overlook, that is, in wallpaper construction, if the glue is not completely dried, there will be a hall wind or a large temperature difference between indoor and outdoor, which will easily lead to wallpaper curling and mildew in the future due to the long-term existence of moisture and air in the wallpaper.

In addition, if there is heavy rain in summer, the wallpaper will easily become moldy due to environmental humidity.

Moldy wallpaper treatment methods:

First of all, if the moldy wallpaper area is relatively large, or there are many, and you think it will look bad even if it is repaired, and you want to change the style, then simply replace it;

if the wallpaper is not very moldy, your wallpaper is of good quality, and it's still time to remedy it. First of all, it is recommended to wipe it with soapy water or detergent. If not, wipe it with cloth soaked in disinfectant alcohol. If it is not too serious, wipe it two or three times to remove the mold.

another way to remove mildew is to use bleach. But it is easy to irritate the skin, so be sure to wear rubber gloves when using it, and use water too clearly. Some people may be worried that bleach will not be used and that the original color will be removed. Then use some special mildew remover to treat mildew spots on walls. You can ask at the wallpaper shop.

how to prevent moldy wallpaper?

1. Choose breathable materials

At present, there are many wallpaper materials on the market, such as non-woven fabrics, wood fibers, PVC, glass fiber substrates, cloth covers, etc. Relatively speaking, PVC wallpaper is the most airtight, and it is the easiest to trap the water vapor discharged from the wall, and it is easy to form mildew spots after a long time.

2. Keep the wall dry

The wall must be kept dry, and the new cement construction generally needs to be maintained for 2 to 4 days before the wallpaper can be laid. It is worth noting that when decorating, we should pay attention not to let the irregular construction mix in the sea sand that is not suitable for wall painting. Sea sand has a high salt content, and it is easy to absorb water, which has buried a "flood" for the later wall.

before putting up wallpaper, you need to prepare the base surface. If it is a second-hand house renovation, the gap in the wall must be filled in, otherwise the wallpaper is easy to empty.

3. Pay attention to the quality of paving.

Three-part material and seven-part project, and pay attention to small details when paving wallpaper on the wall, which can achieve better results. Wallpapers generally have various patterns. When paving, you must 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 drying thoroughly, so it is necessary to leave a good expansion position. Try not to open the contraction joint of the wall to the windward mouth.

4. Insist on use and maintenance

Proper maintenance can prolong the life of wallpaper and enhance its moisture-proof function. Do not open the windows and doors fully during the construction and within 24 hours after the completion of the construction. Excessive ventilation will cause the wallpaper to dry sharply and cause cracks at the joints after uneven shrinkage. After 3 days of paving, attention should be paid to adjusting 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.
