Can the new wallpaper be pasted directly on the old wallpaper?

If the old wallpaper peels off after the service life, it will drive the new wallpaper to peel off together. In this way, the new wallpaper is equivalent to being made for nothing. So be sure to tear off the old wallpaper and do the basic treatment again before you can start pasting new wallpaper.

If there is a steam engine hanging at home, you can use steam to remove the old wallpaper, but you still need a scraper and a utility knife to remove the wallpaper. Press the steam board on the wall until the wallpaper at the edge of the steam board becomes dark due to moisture. Start with the paper tape and gradually peel off the wallpaper from top to bottom. If you can't remove the wallpaper, you can scrape it off with a wall scraper.
