A: The ROMAN Gel Spray Wallpaper and Paste Remover is a no-drip formula that is perfect for tough removal jobs. The clinging gel stays put on walls and remains wet longer than liquid solutions. This makes it highly effective in taking off hard-to-remove wallpaper and paste. Scoring your wallpaper with a ROMAN Scoring tool also allows for the removal agent to penetrate the wallcovering and more quickly start to break down the adhesive. The ROMAN removal agents are designed to help break down starch or clay based adhesives. If a resin based adhesive was used to install a wallcovering, scraping and sanding may be required to remove the wallcovering and the residual adhesive. Thanks for your question!
