Man mixes coppercoat paint under sailboat hull in marina
What this video covers
A couple DIY-refitting a 43-foot sailboat in San Carlos applied Coppercoat antifouling paint to their hull after sanding off old layers.0:40 They hired a local contractor to sand the hull to the substrate, saving weeks of manual labor.1:35 The process involved applying two coats of CK246 epoxy barrier coat, followed by four coats of Coppercoat.1:56 The crew followed a strict two-to-one mixing ratio for the epoxy and adhered to a 20-to-30-minute pot life, which required mixing in smaller batches to prevent premature hardening.2:07 They monitored the barrier coat’s cure time by touch, waiting until the surface was tacky but not transferring residue to their fingers before applying subsequent layers.4:01 After the paint cured for several days, they sanded the hull with 320-grit sandpaper to expose the copper particles, using Scotch-Brite pads for crevices and hard-to-reach areas.14:14 The project required over 60 hours of manual sanding.24:40 Proper surface preparation and strict adherence to cure times between coats are essential for a successful Coppercoat application.
