INLAND FINISHING PROCESS
1 CLEANING
2 HOT-DIP GALVANIZING
3 BRUSH-OFF BLAST CLEANING
- All hot-dip galvanized parts shall be brush-off blast cleaned in accordance with SSPS-SP16 to profile surface prior to primer application.
- All parts shall be oven-heated prior to finishing to prevent out-gassing through epoxy primer.
4 EPOXY POWDER PRIMER
- Within 12 hours of hot-dip galvanizing pretreatment all frames and accessories shall receive an epoxy powder primer.
- Epoxy powder primer is applied electrostatically to a dry film thickness (DFT) of 2.0-4.0mils and oven cure in preparation of top coat application.
5 FINAL TOP COAT
The final top coat is your selection to establish the desired color and aesthetic of the finished product. Hope's offers various coatings including acrylic polyurethane or polyester powder top coats. Both coatings have options for custom color matching, different sheens, metallic flakes, and artistic/weathered finishes.
