||Sometimes wallpaper must come down. It is typically a wet mess, but it can be made much easier using the right equipment and products. The hardest thing is wetting the paste long enough to soften it so you can remove it. The perforators and wallpaper removers below ar a good start to this task. The perforators prick holes in the paper to allow the removers to soak through to the glue layer where they can do their work.
