Answer: In some cases
Explanation: We install specialty designer, showcase, museum, historical, and custom wallpapers and wall covering over liner paper. This optimizes the beauty of the artwork, protects the wall covering, the wall, and prevents "bleed through' of dyes and printed inks that are block and hand printed for clients. Some liner papers are specified for ease of removal and installation due to historical value of murals. In rare circumstances some wallpaper can be installed over old wallpaper, yet the risk of failure of the project is increased.

Answer: In some cases
Explanation: It is possible to do this, but not recommended. If you want to do it, you must make sure the underlying paper is all laying flat before you paper over it. You can get some special adhesive for this, and a small roller, to press the seam down and squeeze out the extra paste, then wipe it off. The more layers of paper there are, the harder it is to get all of it off if you want to paint it later. Painting over paper is really bad, because you can't easily get through the paint layer to steam off the paper.
