■ preparation work

Lidongsheng, deputy general manager of Beijing hongnaijiaye building materials Co., Ltd.

3. Check whether there are cracks and potholes on the wall, fill it with putty according to the size, and polish it with sandpaper

soak in warm water to remove the old wallpaper

if the wall in your home already has wallpaper, what problems should you pay attention to when replacing the new wallpaper? Li Dongsheng said that the vast majority of wallpapers used in the past belong to PVC wallpapers, also known as plastic wallpapers. If you replace new wallpapers, this kind of old Wallpapers must be removed

tips: if there is moisture on some walls, don't stick wallpaper, and deal with the symptoms after finding out and removing the root cause of moisture

3 methods to determine the amount of wallpaper

according to professionals, there are roughly 3 methods to calculate the amount of wallpaper: first, the wall area (length × Width) multiply by 1.1 times after calculation; Second, when calculating the wall area, the doors, windows and heating covers are included; Third, it is calculated by three times the ground area

when estimating the wallpaper used on the wall of a room, the area of the room is generally used × 3 ÷ the area of a roll of wallpaper = the number of rolls generally required (a roll of wallpaper is generally 53 cm wide, 10 meters long, and the area is 5.3 square meters). For the sake of safety, add 1 more volume to the number of volumes generally required. However, due to the differences in the structure of individual houses, when determining the actual required quantity, the salesperson or professional should measure and confirm on site

tips: when purchasing wallpapers, make sure that each model of wallpapers you buy is only one production batch number. The best choice of adhesives is the brand with quality assurance and reputation. Before starting work, be sure to spread out and check each roll of wallpaper to see if there is any deformity or obvious color difference
