Scrub each step clean, using steel wool.
Before you paint iron steps, you must take special measures to prepare the metal for paint adhesion or a significant finish failure is certain to occur. Bare iron won't hold a painted finish, because it is nonporous and very smooth. A bonding primer can improve iron's adhesive qualities; however, ordinary latex, oil and acrylic primers won't bond to metal. To create a lasting finish, condition each step by applying an acidic etching primer. Finish the metallic stairs using a strong, enduring coating that will hold up to heavy traffic.
Instructions
1. Scrub the iron steps clean, using a degreasing soap and coarse steel wool. Do not skip this fundamental step, or adhesion will likely prove impossible.
2. Rinse the iron steps, using wet rags. Eliminate all trace residue, or the primer may not adhere.
3. Affix tape to adjacent surfaces to prevent primer and paint overlap.
4. Apply rust-inhibiting galvanized metal-etching primer to each iron step, using a synthetic paintbrush. Start at the top step and work your way down the staircase. Let the iron steps dry for three hours.
5. Wash your synthetic brush in the sink or tub.
6. Apply oil-based enamel to each iron step, using a natural-bristled paintbrush. Start at the top step and work your way down the staircase. Let the iron steps dry for three hours.
7. Use mineral spirits to wash the natural-bristled paintbrush.
