Zinsser® DIF® is a unique wallpaper stripper that employs enzymatic breakdown of wallpaper paste to make wallpaper removal easy. This sets it apart from conventional strippers based on wetting agents or steamers which merely rewet and soften wallpaper paste. The DIF® patented formula combines a new and more effective blend of wetting agents and enzymes that degrade wheat paste to penetrate the paper and actively work to break down the molecular structure of the reconstituted paste.
