Before you paint nickel-plated metal, you must prepare the surface for paint adhesion. Nickel plating is a durable, nonporous surface. This makes it a poor candidate for painted finishes. Before the nickel plating will accept paint, it requires pre-treatment with a special acidic primer, formulated with the ability to etch durable metallic surfaces. Once you've properly conditioned the nickel-plated metal, it can be painted. Apply a durable enamel to avoid flaking. Apply the enamel in the correct manner so you won't be disappointed in the final finish.
Things You'll Need
Professional painter's tape
Heavy-duty fabric drop cloths
Galvanized metal-etching spray primer
Clean the nickel-plated metal with a water-based degreaser, using a coarse sponge. Rinse the degreaser off with wet rags and dry the metal with towels.
Protect portions of the metal you do not want painted by covering them with painter's tape. Protect flooring with drop cloths.
Coat the nickel plating with a galvanized metal-etching spray primer. Spray in a side-to-side, sweeping motion. Maintain an 8-inch distance between the nickel plating and the spray nozzle at all times. Wait four hours for the metal to dry.
Coat the primed nickel plating with spray enamel. Spray in a side-to-side, sweeping motion, keeping the spray nozzle at least 8 inches from the nickel plating. Wait four hours for the enamel to dry.
Do not prime over unwashed nickel-plated metal, or you may have problems with adhesion.
Do not paint directly over unprimed nickel-plated metal, or the finish will peel.
Do not use ordinary latex, acrylic or oil primers on nickel plating, or the finish will flake.
