Zinsser DIF Wallpaper Stripper is a patented wallpaper stripper based on enzyme action for fast and easy removal of wall coverings. With DIF, wall coverings can be stripped quickly and reliably. It contains special enzymes - a unique, patented formulation with a superior more effective blend of wetting agents that speeds up penetration of the wallpaper and re-solubilisation of the paste. In contrast to DIF Wallpaper Stripper, ordinary wallpaper remover solutions merely wet the paper and the paste, and therefore require a lot of scraping and do not work well except on loose sections. Softened paste tends to build up on the scraper blades, blunting them and leading to wall gouging. DIF Wallpaper Stripper eliminates damage to walls caused by removal of uncoated, water-permeable wallpaper. Using DIF Wallpaper Stripper is better than attempting to remove wallpaper with hot water, vinegar and water, or any other home brew solutions. Furthermore, it does not require the use of a steamer. Supplied as a powerful concentrate - just add water. Size 1 litre.
