Can You Apply Wallpaper onto Wallpaper? Can You Apply Wallpaper onto Wallpaper?

Applying wallpaper over wallpaper that is already on the wall is something that can be done in some instances to shorten the time needed to remodel a room. 

Non-Vinyl Coating

You can successfully apply new wallpaper over wallpaper that is already on the wall if the old wallpaper is not coated with vinyl. You can tell this by simply using a wet sponge on a portion of it. If the wallpaper turns a dark color, then the paper is not coated with vinyl. This will mean that the adhesive on the new wallpaper will stick for a better covering.

Eventual Problems

When applying new wallpaper over existing wallpaper you may run into some problems that will not show up right away. 

  • Bleeding of Ink - The old wallpaper's ink can bleed through the new paper after a period of a few months. To make sure this does not happen, hang a test strip for a few months before do ing the entire wall.
  • Strikethrough - Much like the bleeding of the ink, this is when the original pattern shows through the new paper. Again, this can take some time before the paper settles and the pattern appears. 
  • Mold and Mildew - If the new wallpaper is vinyl, or you placed it over a vinyl covered wallpaper, there can be problems with mold builup caused by the wet adhesive not being able to breathe.
