What are wall murals? Wall murals are large, scenic graphics applied to the wall much like wallpaper. Each mural consists of 8 panels, which makes them very easy for anyone to hang. A dry-strippable, cellulose paste is included with each mural, as are easy to follow instructions. Must be installed on a smooth, primered wall. Texture surfaces need to have a wall liner installed first. Wall murals are printed on 80 lb. wet-strength paper. After printing they are finished with a light coat of varnish. They can be cleaned (but not scrubbed) with a wet sponge.
