How to Paint a Metal Stair Banister

Layer the newspaper on the ground around the railings. Cover with large cardboard pieces, and secure with masking tape.

Wear goggles, gloves, a tight-fitting dust mask and clothing that covers your skin.

Mix equal portions of vinegar and water in a bucket. Dip the scrubbing brush in the solution, and remove all the dirt and dust from the surface of the railing. Let the railing air dry completely or wipe with dry rags. Empty the bucket, rinse and fill with water.

Scrape off the chipped paint and rust using the scraper. Attach the wire brush to the drill, and brush the railing to remove most of the old paint and rust. Wipe the surface with a damp rag. Sand the surface to remove any stubborn rust or chipped paint. Rub again with a damp rag. Let the railing dry completely.

Apply a coat of paint conditioner on the bare metal surface. When the conditioner dries, apply a coat of rust-inhibiting primer. When the primer is dry, apply a coat of rust-inhibiting enamel paint suitable for metal surfaces. Back-brush if you need to remove drips or make the painted surface even.
