Once the background of the plaque has been painted, the surface areas are highlighted by sanding (flat areas) or buffing (sculpted areas). To inhibit natural oxidization, a clear, protective coating is then applied.
The Natural metal color with subtle horizontal grain lines meets NAAMM finish designation M33-C11-060.
The natural metal color with subtle horizontal grain lines. Meets NAAMM finish designation AA-M33-C11-R10.
The natural metal color 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 bronze plaque is polished to meet the polished bronze specifications. 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. Painted color can be applied to the recessed areas.
Random-Orbital (Bronze or Aluminum)
The natural metal color with multi-directional brushed lines, achieved with a random-orbital sander. Meets NAAMM finish designation M35-M4x-C10-O60-ideal surface treatment for cast plaques mounted in a sidewalk subject to pedestrian traffic.
In order to protect the natural, highlighted finish of a cast bronze or a aluminum plaque, 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.)
- Diamond Shield® Protective Coating
This 2-part coating for protection in the harshest environments. Diamond Shield® can be factory-applied only 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. Diamond Shield® is particularly effective in harsh, exterior environments, where 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 used by Saxton does not lend itself to polishing. Polished aluminum plaques are not available.
- Diamond Shield® is our standard clear, protective coating. Unless otherwise specified, all plaques will receive Diamond Shield® clear protective coating.
