DIF Ultra is five times more concentrated than the original DIF liquid concentrate wallpaper stripper and makes 8-16 gal.s of formula, enough to remove wallpaper in four 12 ft. x 24 ft. rooms
If top layer does not peel off easily, score with paper tiger tool to allow DIF to penetrate
Made the job much harder than needed! Use a power steamer!
I read a bunch of "expert" DIY sites and decided to use this product to strip my wallpaper. First I scored with a paper tiger. Next I sprayed enough DIF onto the wall to constitute an EPA cleanup site. I waited the proper amount of time and began to scrap. 5 hours later, I had completed 3/4 of 2 walls measuring 5x10 (high ceilings). And, stubborn glue required aggressive scraping and gouged my walls.
1.5 hours with a Wagner power steamer and I stripped 3/4 of another 5x10 wall, and hardly made any damage by comparison! The paper practically fell off with the power steamer!

Finally got the job done
I had tried vinegar, and the blue spray stuff, but this is what finally got the last little pieces of glue off of our walls. If your wallpaper wasn't put on properly, this should help get that last of the glue off!

If you're looking to remove wallpaper and not just wallpaper glue, stick with the blue gel DIf, which is great.
