Zinsser® DIF® Gel penetrates and loosens wallpaper while also softening residual paste left behind by wallpaper. Its gel consistency makes it easy to apply and eliminates the mess of steamers and liquid solutions by clinging to walls and even ceilings. It's economical too! By staying wetter longer, only one application is usually needed, saving both time and money. Its enzyme-based formula is highly effective in removing wallpaper quickly and completely while also being safe, non-toxic, and odorless.
