This is peel and stick.  That's half right, it peels but it sure doesn't stick.  I prepped the wall with TSP and had already put peel and stick back splash on another area, it stuck like a champ but this stuff, it doesn't stick at all.  I even tried it on a area I painted over a year ago and it doesn't stick there as well.  If I wanted to put up wallpaper that needed glue, I would have bought traditional wallpaper.  Very disappointed with this.
