Can you paint over cabinets that are already painted?

The answer is yes, you can paint over cabinet that are already painted. As always, in order for any paint to adhere properly, you must prepare the surface the right way. If the old paint is peeling, it must be scraped away where it has come "loose" from the wood. Other prep steps include thoroughly washing and drying the surface clean. You must make sure it is completely free of all oils and food as paint will not adhere to these substances. If they are left on the surface, you'll get an uneven, imperfect coat that is likely to peel or bubble. Sanding must then be completed to remove imperfections and create a smooth surface. Sanding is also necessary for developing small, rough ridges which create adhesion for the paint to stick to. When all doors, drawers and boxes have been properly prepared, you can start with your first coat of paint, followed by a second if necessary. The second coat should be applied after the first coat is completely dry.
