Step 1
Remove all paint and rust using either sandpaper or a chemical remover. Both items are available at hardware and home improvement stores. For severely rusted wrought iron, a chemical remover is best. When you are finished, you want to be able to see the silver iron underneath.
Step 2
Wash the wrought-iron furniture thoroughly to remove any excess paint, rust or sandpaper debris. Allow the furniture to dry completely.
Step 3
Spray or paint on a rust-resistant primer that is made especially for metal surfaces. Again, these primers are available at hardware and home improvement stores. This will protect your furniture from future rust.
Step 4
Paint the wrought-iron furniture with paint made especially for metal surfaces. Do not use house paint, as it will peel very easily on metal surfaces.
