. . . It's an Art
The below finishing process steps apply to wet coat finishes only. All our posts, finials, bases, and other mounting accessories are coated with high grade powder coat finishes.
Step 1: After production is complete all signs are cleaned with a combination of sand blasting media and solvents to ensure a clean surface that is ready to accept primer and paint.
Step 2: Using HVLP spray equipment, a heavy coat of automotive grade epoxy primer is applied to the surface of your sign or marker. Additional sanding and primer coats are applied as needed.
Step 3: Using a 3-part Urethane enamel (Matthews Paint System), signs are coated with the appropriate color. Multiple coats may be required depending in the sign type and application.
Step 4: Once the sign or marker is coated it is force dried/baked in industrial ovens at 200 degrees Fahrenheit for 30 minutes to fully cure the paint.
Step 5: Dimensional Signs and plaques are satin polished on the raised portions to expose the natural metal surface. Signs requiring a painted raised surface/characters are hand painted with a 2-part lettering enamel.
Step 6: Signs are then cleaned with compressed air and tack cloths to remove any dust or debris from the polishing process. Any product with a satin polished or exposed metal surface is coated with a Spray Bond Adhesive to promote adhesion of clear coat to the bare metal surface.
Step 7: Signs are coated with a 3-part urethane clear coat and baked again for 30-40 minutes in our industrial ovens. Bronze/Copper alloys get a special formula clear coat (Braco Clear) that helps prevent tarnishing (see below).
Step 8: Once completely cooled, each sign is checked for minor touch-ups, verified for the correct mounting setup, and packaged with the appropriate hardware for shipment.
