Homeowners can tell if it is a true paper by using a sponge.
Can i paper over vinyl wallpaper.
Wallpaper without vinyl coating is the only wallpaper that can guarantee success.
True paper papers are generally high end products or are made overseas.
If the existing wallpaper is firmly adhered to the walls and has a smooth texture free from any embossing raised embellishments or flocking you can add a fresh layer of wallpaper over the old.
Ease up these pieces of vinyl with a wallpaper scoring tool to allow the wallpaper remover to get beneath the vinyl and to the adhesive.
A safe way to determine if your new wallpaper can be applied over the old paper is to see if you can tell what kind of wallpaper is currently on the wall.
In most cases non coated paper can be wallpapered over.
Some parts of the paper may be more difficult to remove.
If the vinyl rips off in strips loosen another corner with your scraper and continue pulling until you have removed the entire top layer of wallpaper.
However vinyl coated paper cannot be wallpapered over.
The only wallpaper that is nearly guaranteed not to cause you residual problems if you leave it on the walls is non coated wallpapers.
