You can refinish your own resin furniture and restore it to an almost-new condition if it looks like it's fading or needs updating. Resin is made from polyethylene and looks very shiny, like plastic. It is a good finish for outdoor or patio furniture because it tends to resist scratches and dents. In order to paint over resin, you will need some high-bond paints made specifically for use with plastics and resin.
Clean the resin wicker by spraying a mold and mildew remover product on it. Wait a minute for it to soak before you wipe it down with paper towels. Dry it completely.
Set the wicker outside or in a well-ventilated area before applying any paint.
Wear gloves and lay down newspapers or drop cloths.
Apply a coat of primer paint made specifically for resin (see Resources). Use a natural bristled paintbrush and make the coat very thin so it doesn't clump over the wicker strands. Let it dry for 24 hours.
Apply a light coat of paint over the dry primer with a spray can. Use light, even strokes to coat the wicker, holding the can about a foot away from the furniture.
Paint a second coat when the first coat has dried completely. Let it dry for 48 hours before using the furniture.
