Do I need to sand before I paint?
Chalk Paint® decorative paint adheres to almost any surface, indoors and outside, and there’s rarely a need to sand or prime. Most times simply cleaning and dusting off the surface will do. There may be times, however, when you’ll need to sand to remove loose paint, rust, and other surface debris, or when the surface is glossy or made of melamine or laminate. Use medium to fine grit sandpaper and remember to change it out when it becomes clogged; a fresh sheet makes the task at hand easier to accomplish.
