We inspected an above-ground exhaust duct in preparation for future epoxy spray coating. The ductwork, crucial for proper ventilation, showed signs of wear and required protective treatment. By applying an epoxy coating, we aim to enhance the duct's durability and resistance to corrosion. This proactive measure will extend the lifespan of the duct system and improve overall efficiency. Detailed plans for the coating process will be provided to ensure optimal results.
