Masking tape, also called painter’s tape, performs various functions during painting work. First of all, it protects furniture, floors, power strips and other items from paint splatters, allowing you to focus on the job at hand. Plus, properly applied masking tape can help you create clear edges on your wall or wallpaper. After you’re done painting all you have to do is peel off the tape for painting with care. What you’re left with are straight lines, a clean work environment and beautifully painted walls.
