First start by removing all hardware, handles and hinges. Then, using sand paper, sand all surfaces of the cabinet and the cabinets door. After sanding is complete, vacume all dust and wipe down all surfaces. Use a water based paint and brush on with a roller. Allow to dry overnight.
Remove all cabinets and brackets. Clean with Windex to remove the build up of grease and dirt, let dry. Thrn lightly sand with sandpaper to make surface a little rough so the new primer and paint will stick to the cabinets. Be sure to wipe off any dust before applying your paint.
