Painting Surface
Brass
Brass is a copper-zinc alloy with a smooth nonferrous surface that can tarnish and accumulate polishing residue. Reliable paint adhesion depends on thorough cleaning and a coating system suitable for nonferrous metal.
Brass paint compatibility
Acrylic, spray, and enamel coatings can work on brass when tarnish and contamination are removed and the primer or adhesion system is suitable for nonferrous metal.
| Paint | Compatibility | Preparation | Primer | Finish | Guide |
|---|---|---|---|---|---|
| Acrylic paint | Good for decorative use with adhesion preparation | Remove grease, tarnish, wax, and polishing residue; dull the surface when the selected system requires it. | Use an acrylic adhesion medium or primer approved for nonferrous metal. | Use a compatible protective finish when the item will be handled frequently. | — |
| Spray paint | Good with a metal-compatible product | Clean and degrease thoroughly and remove tarnish or loose surface deposits before coating. | Use a bonding or nonferrous-metal primer unless the aerosol coating approves direct application. | Choose a product rated for the intended interior or exterior exposure. | — |
| Enamel paint | Good with a compatible metal system | Remove contamination and tarnish, then prepare the surface to the enamel manufacturer's requirements. | Use the specified primer for clean nonferrous metal or other difficult-to-adhere surfaces. | Allow the coating to cure fully before heavy handling or exposure. | — |
