Zinsser DIF® Concentrate – Fast-Acting Enzyme Wallpaper Stripper
Zinsser DIF® Concentrate is a powerful, patented wallpaper stripper formulated with special enzymes that break down old paste for fast, clean and effortless wallcovering removal. Unlike ordinary removers that simply wet the paper, DIF® penetrates deep into the adhesive layer, dissolving paste completely to prevent wall damage and eliminate heavy scraping.

Designed to strip wallpaper quickly, safely and efficiently, DIF® works on uncoated, multi-layered and hard-to-remove wallcoverings without the need for steamers, harsh chemicals or home-made solutions like vinegar mixes. Its superior wetting agents allow it to outperform conventional removers, ensuring a smooth, gouge-free finish.

Key Features:

• Fast-acting, enzyme-based wallpaper stripping formula

• Patented technology for deep penetration and paste breakdown

• Reduces scraping and prevents wall gouging

• Works better than hot water, vinegar mixes or standard removers

• No steamer required – safer, cleaner and more cost-effective

• Removes tough, uncoated and stubborn wallpapers with ease

• Helps avoid paste buildup on scraper blades

Surface Preparation

DIF Fast-Acting Liquid can be used to strip most types of wallpapers that cannot be effectively peeled or dry-stripped from the walls. These include: traditional paper wallpapers, vinyl-coated papers, paper-backed vinyl wallpapers, solid vinyl wallpapers, foils, mylars, grasscloth, textiles and even painted wallpapers. (Borders – see section – Removal of wallpaper borders.)

Technical Data

Coverage
One gallon of DIF Fast-Acting Liquid will cover a little over half of a 10’ x 12’ room with 8’ ceiling (approximately 300 square feet or 6 bolts of wallpaper). Note that coverage will vary with porosity of wallpaper and thickness of product application.

Directions for Use

Determining Where to Begin RemovalThe type of wallpaper will determine where to begin the removal process. Grasp a seam or an edge of the all paper and try to peel it off. Remove any layer that will peel off first and then apply DIF Fast-Acting Liquid to the remaining backing paper or residual adhesive. Stop if attempts to dry strip the existing wallpaper fail or result in damage to the drywall, and refer to the instructions below for removal of specific types of wallpaper.
• Traditional Paper Wallpaper
Traditional paper wallpaper is uncoated, porous and will absorb removers readily. No further preparation is necessary before applying DIF Fast-Acting Liquid.
• Coated Wallpaper
If wallpaper is a washable type (generally a standard paper that is coated with a vinyl or acrylic coating) score* the surface using the Zinsser Paper Tiger scoring tool to enhance DIF Fast-Acting Liquid penetration. Score the wallpaper from the ceiling to the floor, using just enough force to break through the surface of the wallpaper.
• Painted Wallpaper
If the wallpaper has been painted over, score the surface thoroughly using the Paper Tiger scoring tool.
• Vinyl Wallpaper
Most vinyl wallpapers are either peelable (the top layer can be removed, leaving the paper backing behind) or strippable (the entire sheet of wallpaper can be removed, leaving only adhesive residue behind). Always try to peel or strip the wallpaper first and apply DIF Fast-Acting Liquid to the paper backing or adhesive residue. If the vinyl wallpaper cannot be peeled or stripped off, score the surface thoroughly with the Paper Tiger before applying
DIF Fast-Acting Liquid.
• Foil, Mylars, and Other Sealed Wallpapers
Thoroughly score the surface with the Paper Tiger before applying DIF Fast-Acting Liquid.
• Textiles
If textile has been installed directly over adhesive, simply apply DIF Fast-Acting LIQUID. Some textiles need their surface scored with the Paper Tiger.
• Multiple Layers of Wallpaper
It may be necessary to remove the wallpaper one layer at a time since multiple layers can resist full penetration of the scoring tool.
*When using the PaperTiger, apply only enough pressure to penetrate the wallpaper to avoid damaging the drywall. The more holes the better. If unsure, test a small area
before proceeding.
