I'm thinking of installing the same tile that's already installed on my kitchen floor on the backsplash. The subsurface would be sanded masonite wallboard. Has anyone ever SUCCESSFULLY used self-stick vinyl tiles on a WALL? Could this be done with the tiles as-is, or perhaps with a SPECIAL ADHESIVE? I need a helpful "veteran" for this one -- I'm pretty handy, but have never attempted this one before, hate to make a mess and waste tile for nothing!
