Wear protective gloves and eyewear, and follow the steamer manufacturer’s instructions for correct use. Allow the steamer to heat up for about 10 minutes, then starting at the bottom of the wall, hold the plate directly against the paper and wait for 60 seconds or until the paper around the plate shows signs of damp. Take extra care when stripping wallpaper from a plasterboard wall. The plasterboard surface is paper and very fragile so use the scraper gently to avoid digging into the wall.
