Air humidity should pay attention to: when the wallpaper is constructed, the relative humidity of the indoor air should be no more than 85%, so choose the right weather. During construction, the room should be clean, free from dust and debris, and doors and windows should be closed during the day and night to avoid construction on wet walls.
If the wall has been damp, it is best to brush the base film or clear oil after the wall is dry. Fang Dianxiang said that if the wall side is a bathroom, the interior wall of the bathroom must be specially treated with a waterproofing agent, otherwise the wall will be damp for a long time and the wallpaper glue will be invalidated.
It is recommended to first clean the oil on the wall, do wall protection and protect it from moisture. After drying, use sandpaper to polish it gently. However, Fang Dianxiang also reminded that the oil should be brushed up to two times, otherwise the wall surface will be too smooth, so that the wallpaper will not stick to the wall surface, and seams will easily occur during the drying process.
Note the use of glue: high temperature in summer, formaldehyde and benzene present in decorative materials are also easy to volatilize, so it is necessary to pay attention to the environmental protection of decoration. When paving wallpapers, try to use non-toxic and environmentally friendly wallpaper glue, please professional wallpaper construction unit. Generally, you can choose potato starch glue, glutinous rice starch glue, and some wallpaper brands will provide special glue. In addition, there are some wallpaper glues for children's rooms on the market.
Pay attention after construction: in the spring because the air is humid, in order to let the walls dry as soon as possible, open the doors and windows to ventilate and breathe. Summer is different, because it is dry, so the wallpaper should be thicker before the paving, put it for 15 minutes, then lay it.
If you want to open the doors and windows at this time, let the wallpaper that has just been paved blow "wearing the wind", the wallpaper will shrink and deform due to the rapid loss of water. Fang Dianxiang reminds the owner to turn off the air conditioner during construction to prevent excessive wind and temperature changes, otherwise it will easily cause surface irregularities, drums, joint cracking, jointing and warping. It is necessary to maintain ventilation for 36-48 hours after construction in summer.
