Hva denne videoen dekker
Extensive hull repairs on a Lagoon 450 catamaran involve removing blistered, moisture-damaged fiberglass along the entire centerline of both hulls and rebuilding the structure with biaxial glass and epoxy.0:12 The repair process requires grinding out damaged sections, filling voids with thickened resin to prevent air bubbles, and layering fiberglass to exceed original structural strength.2:03 Above the waterline, the crew uses polyester resin to ensure compatibility with subsequent gel coat applications, while below the waterline, they use epoxy for its superior waterproof properties.3:13 The team addresses a specific bow impact site by building up 20 layers of glass and fairing the surface with structural putty containing milled glass fibers.0:48 To ensure proper curing of polyester-based fillers above the waterline, the crew adds wax to the mixture to create an air barrier.20:22 The project also includes reinforcing the keel and managing moisture levels in the engine room area before final glassing.16:59
