Starting for paint metal dining room chairs, bring your chairs in a large, well-ventilated area, such as your patio or garage. Protect your floor, around furniture or nearby walls with the collection cloths. Remove any cushions or padding. Check under the chair to see if the seat cushions are screwed in and unscrew if necessary. If any padding or cushions cannot be removed, protect them by covering them with plastic bags and painter’s tape. Put on old clothes, goggles and a dust mask. Put on gloves to protect your hands.
Painting preparations, refine the finished rust or peeling with a stiff wire brush. If the chairs do not rust and peel, pass the wire brush. Sand your chair with an electric palm sander. Use a heavy one for medium grain sandpaper first if there is a lot of chips and scratches on the surface of your chairs. Finish with a pass of fine sandpaper. If the surfaces of the chairs are in good shape, go right to the fine grain sandpaper.
Clean your chairs well with an ammonia-based window cleaner and a cloth. Spray and clean from top to bottom, including below. Enter any crevice or creases with a cotton swab or an old toothbrush. Let air dry.
