Crew spray gelcoat on catamaran hull at water level
Τι καλύπτει αυτό το βίντεο
Parlay Revival's crew in Langkawi, Malaysia, sprays gelcoat on a Lagoon 450 catamaran to repair blistered hull sections above the waterline, cracked gelcoat at cleats that lacked backing plates, sugar scoop dings, and a large bow repair from a log strike.10:29 Mubin, a professional sprayer with 20 years' experience, uses a spectrophotometer-style color scanner to match the hull's factory white, then adjusts the Jalko gelcoat with TotalBoat pigments — adding yellow to correct an excess of blue — until the meter reads near-perfect.2:46 The spray mix uses a high-volume, low-pressure gun at 50 PSI, 10% styrene monomer to thin the gelcoat, 1% MEKP hardener in the heat, and 4% wax in the final coat to achieve a tack-free cure.9:27 When the wax percentage proves insufficient on the first session, hairspray applied over fresh gelcoat creates an air barrier that allows full cure and washes off cleanly with water before wet sanding.7:59 Four coats are applied so enough material remains after sanding out orange peel.10:40 The waterline is raised one inch during the respray.13:14 Separately, water-logged rudders are dried, fitted with temporary fiberglass walls, and filled with expanding foam under a tight 45-second working window.17:24 Hairspray is a practical substitute for PVA when sealing small gelcoat patches against air inhibition.
