1, new wallpaper

If the wallpaper is moldy and serious, even if it can be washed off, it will not look good, and I think it is time to change the style, then simply replace these wallpaper with some new ones.

If the wallpaper is not very moldy, it can be remedied by cleaning it in time. First of all, it is recommended to wipe the wallpaper with soapy water or detergent. If the mildew is not too serious, it can be removed after two or three rubs.

Bleaching water will remove the original color. So you can choose some fungicides to deal with mildew spots on the wall, and you can ask in the shop where you buy wallpaper.

Second, about the causes of moldy wallpaper

1, moldy due to season.

If it is mildew caused by seasonal reasons, it is best not to repair it immediately. Because the water in the wall is gradually evaporating, if the water is not completely evaporated and a new layer of paint is painted, the water on it will continue to evaporate and come out from other places. At this time, the wall will continue to be moldy.

2. Wall insulation is not done well.

If it is moldy because the wall insulation measures are not done well, first check whether the wall has been insulated. Knock on the wall with an inspection hammer. If the sound is hollow, it means that the wall has insulation layer. If the sound is dull, it means that the wall has no insulation layer. If there is an insulation layer, it is necessary to check whether there are cracks in the external wall of the building. If there are no cracks, the insulation material is unqualified and needs to be replaced.

Three, about the prevention of wallpaper mildew

1, select breathable material.

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 has the worst air permeability and is most likely to lead to mildew.

2, keep the wall dry

The wall must be kept dry, and it is best to leave the newly built wall for 20 to 40 days before laying wallpaper. 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, otherwise it will easily lead to empty drums.

3, pay attention to the quality of the shop is stuck

Three-point material and seven-point project, when wallpaper is on the wall, attention should be paid to small details, which can achieve better results. Wallpapers generally have various patterns. When paving, be sure to pay attention to whether there is a big one between two wallpapers. 4. Adhere to the use and maintenance.

Proper maintenance can prolong the life of wallpaper and enhance its moisture-proof function. It is best not to completely open doors and windows during the construction and within 24 hours after the completion of the construction. If the wind is too strong, the wallpaper will dry sharply and shrink unevenly, which will easily cause cracks at the joints. After paving for 3 days, pay attention to adjust the ventilation. Open the doors and windows during the day, keep the ventilation, and close the doors and windows at night to prevent moisture from entering, which can make the wallpaper stick more closely.
