Our product is designed to work on smooth surfaces such as painted drywall, glass, and smooth painted metal. Of course it's your choice (and who are we to tell you what to do!), but we don't recommend using our wallpaper for unpainted drywall, brick, textured wallpaper or drywall, or any other textured surface.
If you have any questions and aren't sure what your surface qualifies as, shoot us an email at hello@yellowpop.com with some photos and a description and we'd be happy to assist!
