The main points of construction of the wallpaper: 1) Remove the wall covering to remove the original paint, wallpaper and other objects on the wall; if there are cracks or potholes on the wall, use gypsum powder to fill these places, put a bandage on the flat surface; The partition wall should also be covered with glass cloth or a good cloth; some partition walls or outer walls with poor quality should be filled with gypsum board to achieve the effect of heat preservation; 2) Brush base oil: evenly brush the alkyd varnish on the wall surface, the thickness is moderate; 3) Putty putty and sanding: Put the putty on the wall twice. After the putty is dried, sand the wall with sandpaper, and rub the uneven particles to make the wall smooth and flat; 4) Cover oil: Evenly paint the wall surface with clear oil, no need to be too thick. This prevents the wall from absorbing wallpaper glue, making the wallpaper stick to the wall and making the wall flatter; 5) Crop wallpaper: crop wallpaper also has regularity, such as each wallpaper and two adjacent wallpapers, the pattern is neat, the size is consistent, and so on; 6) Post wallpaper: After the wallpaper glue is evenly applied to the wallpaper with a roller, it needs to be placed for a thicker wallpaper for a while. When you start to affix the wallpaper, for the seams, the two sides of the adjacent wallpaper are squeezed together to make them match, and then the seam is pressed with the squeegee and the extruded glue is cleaned. After the wallpaper is pasted, use the scraper to flatten the wallpaper from top to bottom.
