Painting an old vinyl chair is simple, but don't use just any paint you have on hand. In general, paint and vinyl don't go together well. In no time, the paint will start to peel off, leaving you with a chair that looks worse than before. Instead, purchase specialty vinyl spray paint, which allows it to adhere to flexible vinyl surfaces. You can find vinyl paint at most home and garden centers.
Clean the chair thoroughly with a solution of 1/2 cup of oxygen bleach and 1 gallon of hot tap water. Use a scrub brush to remove stubborn grime. Rinse and wipe dry with a microfiber cloth.
Cover any nonvinyl parts of the chair, such as chrome or wood, with painter's tape.
Place the chair on a drop cloth outdoors.
Shake the can for one minute. Hold the can 10 inches from the vinyl, and spray an even coat of paint on the surface. Allow the paint to dry for five minutes, or as recommended by the manufacturer, then apply a second coat.
Allow the vinyl paint to dry overnight before use.
