The Annie Sloan Chalk Paint (ASCP) states you don’t have to sand or prime but if you are re-doing cabinetry, either bathroom or kitchen, I would at least give them a good clean with detergent to remove oil, grease, or any residue before painting. I did do a test board that was sanded and another that was not sanded: the sanded side had better paint adhesion and a smoother, end appearance.
