Interior décor always changes, but things like wallpaper borders can be hard to remove. Try these steps to make the job a little easier. Sometimes a change in décor is necessary, but removing wallpaper borders can be a tricky job, especially if the adhesive still holds strong. Note: Painting over a wallpaper border is also an option when changing a room design. Step 1 – Try the Hairdryer Trick Before you apply any water or other moisture to the wallpaper and border, gently heat the area with a hairdryer. After you’ve left the heat on it for a few minutes, pull at the border gently to see if it will come off. If you have no luck, the adhesive used was likely strong and a different approach will be required.
