Can I paint over a piece that has been previously painted?

You can! If your previous finish is loose, peeling or chipping, you're going to want to sand away the loose and get a smooth surface. If your previous finish is full of texture, our paint will self-level into that texture. You can sand it smooth for best results. You do not need to strip or sand to bare wood. Once you have the issues address, you're good to Just Clean & Paint!
