Before painting your metal lawn chairs, gather a few materials together to ensure a successful refinishing. These include rags, dish soap, steel wool, goggles, rust remover, paint brush and metallic spray paint and primer.
Clean and prep the chair for painting
Dip a rag in a mixture of water and dish soap. Wipe the rag across the surface of the chair to remove dust, dirt and all other debris. Once you've cleaned every surface of the chair, rinse the soap off thoroughly.
Inspect the chair for rust
Examine the chair for rust, peeling paint and corrosion. Use a wire brush or a piece of steel wool to remove any rust or peeling paint from the chair's surface. Brush on a coating of rust remover and let it sit overnight. Rinse and wipe the chair dry the next day.
Apply a coat of primer
Place the chair on a drop cloth in a well-ventilated area. Apply a light coating of mildew-resistant spray-paint primer to the chair. Wait until the first coat is completely dry before applying a second. Let dry for 24 hours.
Paint the chair
Apply several coats of rust-resistant spray paint to the chair. Wait at least one hour between coats. Wait 24 hours before using the chair.
