Surface finishes for bronze plaques
Once the background of bronze plaques have been painted, the surface areas(these are the raised letters of lines of artwork) are highlighted
by sanding (flat areas) or buffing (sculpted areas). To inhibit natural oxidization, a clear, protective coating is then applied.
Satin Bronze The Natural metal color with subtle horizontal grain lines meets NAAMM finish designation M33-C11-060.
Polished Bronze The natural metal color is buffed to a high gloss, obtained by polishing with successively finer abrasives, then buffing with fine buffing
compound. Meets NAAMM finish designation M42-M22-C10-060.
Chrome Plated Bronze The raised surface of the plaque is polished. The background of the plaque remains in its "natural sandblast" state, providing contrast with the polished raised surface. The entire plaque is then electro-plated using a standard commercial copper/nickel/chrome plating process.
In order to protect the natural, highlighted finish of bronze plaques, two options are available:
Clear Protective Lacquer Providing a low gloss appearance, this clear coating was developed to help ensure many years of carefree maintenance.
This option should be selected when matching older plaques or when a lower gloss look is desired (particularly for interior applications.)
Polyurethane Protective Coating A 2-part coating for protection in the harshest environments. This clear coat can only be factory-applied and provides maximum protection. This coating is applied with a heavier thickness than our clear protective lacquer and is available in a high gloss version only. It is
particularly effective in harsh, exterior environments, where bronze plaques are exposed to salt, pollution and weather.
- The maximum size available for polished bronze plaques is 48" x 36". A polished finish is not recommended when there are large raised areas
due to normal surface inconsistencies inherent in the casting process.
- The casting alloy of aluminum does not lend itself to polishing. Polished aluminum plaques are not available.
- Polyurethane is our standard clear protective coating for outdoor plaques. Unless otherwise specified, all plaques will receive this clear protective coating.
