Qué cubre este vídeo
Applying Coppercoat antifouling to the hull of the sailboat Athena requires extensive surface preparation, including removing amine blush from the previous barrier coat and sanding the entire hull to ensure a mechanical bond.1:12 Before application, the crew must repair pinholes in the fairing compound by drilling them out and filling them with thickened epoxy.3:58 The Coppercoat process involves mixing resin, hardener, and copper powder, ideally at temperatures between 20 and 25 degrees Celsius to improve workability.8:31 Using a team of four, the crew applied six coats to the hull, averaging one hour per coat.14:07 The product requires a final abrasion step three to four days after application to expose the copper particles encapsulated in the epoxy.20:08 While the initial cost is higher than traditional antifouling, the long-term expense is lower for liveaboards who avoid annual haul-outs.16:15 Proper preparation and a multi-person team significantly simplify the labor-intensive application process.
