Wall decoration steps

1. Paper-walled walls refer to walls that are pasted with wallpaper, wall coverings, etc.
(1) The structure of the pasted wall: use cement lime mortar to make the wall flat. After drying, scrape the putty completely and smooth it with sandpaper, and then paste the wallpaper with 107 glue or other adhesives.
(2) The main technological process of mounting wallpaper and wall covering: Cleaning the base layer and filling the gaps → pasting joint tape, patching putty, sanding paper at the joints of gypsum board surface → scraping putty, smoothing → applying moisture-proof agent → applying bottom Glue → wall elastic line → wallpaper soaking → wallpaper, base layer coating adhesive → wallpaper cutting paper, brushing glue → wall mounting, patchwork, lap joint, registration → pressure adhesive bubbles → wipe off glue → trim .
(3) Key points for the installation of wallpaper and wall covering:
1. When the base layer is processed, it must be cleaned, level and smooth, and the moisture-proof paint should be applied evenly and not too thick. (1) Concrete and plastering base layer: clean the wall surface, and level the surface cracks and potholes with putty. Scrape the putty again and smooth it. Decide the number of times to scrape putty according to your needs. (2) Wood base layer: The wood base layer should be planed flat, without burrs, stubble, and no exposed nail heads. Fill the joints and nail holes with putty. Fully scrape putty and smooth it. (3) Gypsum board base layer: gypsum board joints are treated with caulking putty, and the joints are taped firmly. Scrape putty on the surface. 107 glue is generally used for painting the primer, and the primer will survive once, but there must be no omissions.
2. In order to prevent the wallpaper and wall cloth from falling off due to moisture, a layer of moisture-proof paint can be applied.
3. Play vertical and horizontal lines to ensure that the wallpaper and wall covering are horizontal and vertical, and the pattern is correct.
4. Plastic wallpaper will swell when exposed to water and glue, so it is necessary to moisten the paper with water to fully expand the plastic wallpaper. Wallpaper and wall coverings made of glass fiber substrates will not expand or contract when exposed to water and do not need to be moistened. Composite paper wallpaper and textile fiber wallpaper should not be stuffy.
5. After pasting, press the wallpaper adhesive quickly to avoid leaving air bubbles, and wipe off the glue in time.
