O que este vídeo aborda
Adriano Plotzky repairs localized osmosis blisters on the hull of his boat, Balanço, by sanding down to the gelcoat and drying the laminate.0:14 Although no blisters were visible before sanding, the process revealed small, vinegar-scented droplets trapped in the fiberglass.0:18 To identify moisture levels, he uses a 160-real moisture meter purchased in Curitiba, which allows him to compare relative humidity across different hull sections.0:40 Because the meter lacks specific fiberglass calibration, he uses it to pinpoint areas requiring targeted drying rather than relying on absolute percentage readings.0:47 To accelerate the drying process in cooler weather, he constructs a plastic greenhouse enclosure around the hull to trap solar heat.1:36 After cleaning the opened blisters with acetone and a hair dryer, he fills the voids with a mixture of epoxy resin, hardener in a 60-40 ratio, and fiberglass microspheres.3:12 He uses a scale to ensure precise mixing ratios and applies the filler with a spatula, later sanding the cured patches flush.3:45
