Application:

• Apply enough DIF Fast-Acting Liquid to leave a thick layer of stripper on surface of the wallpaper.
• When rolling use slow, steady rolling motions to avoid splattering the stripper.
• Be sure to apply in corners and tight spots.

Wetting Period:

• DIF Fast-Acting Liquid functions much like paint remover, i.e. it must penetrate the wallpaper and loosen the adhesive.
• Reaction time will vary depending on the type of wallpaper being removed as well as the type of adhesive used.
• Most wallpaper will be ready for removal 2 – 10 minutes after DIF Fast-Acting Liquid has been applied.
• Some types of wallpaper may take longer.

Removal:

• Use the Zinsser Paper Scraper to remove loosened wallpaper.
• Place blade of Paper Scraper at top edge of side of wallpaper section and gently slide underneath wallpaper to separate it from the wall.
• For stubborn areas, reapply DIF Fast- Acting Liquid and wait an additional 15 minutes before removing.

Adhesive Removal:

• Apply DIF Fast-Acting Liquid and allow to soak until the adhesive is loose and can be sponged or scraped off with the ZINSSER Paper Scraper or a wide putty knife.
• DIF Fast-Acting Liquid will remove starch-based adhesives, but not non-water soluble vinyl-over-vinyl or border adhesives.
• **The ZINSSER Paper Scraper is a tool specially designed to remove loosened wallpaper and old adhesive without gouging or cutting the drywall.

Cleaning adhesive:

• After wallpaper has been removed apply a thin layer of DIF Fast-Acting Liquid to walls to remove any remaining
  adhesive.
• After 10 minutes rinse the surfaces and adjoining areas very well with water.
• Look to see that all of the stripper solution is removed.
• Be sure to change rinse water frequently to avoid recontamination of the walls.
• If there is mildew, use a household mildew cleaner to destroy any mildew that may be present.
• Rinse walls and allow to dry before painting or installing new wallpaper.

Tool Clean up:

• Wash roller, brush, and any trays, pans, or buckets with warm tap water
