Colin and Jamie repair large sections of delaminated balsa core on the Lagoon 450 catamaran Parlay Revival.0:06 After grinding away the damaged outer laminate to expose the inner skin, the crew prepares the site by cutting the replacement balsa core to size and organizing numbered layers of biaxial fiberglass.1:03 To compensate for the replacement core being thinner than the original, they apply an initial layer of glass against the inner laminate to restore structural integrity.1:03 The process involves applying filler, seating the balsa, and laminating three layers of biaxial glass in a single session.1:17 The team emphasizes thorough preparation, including pre-cutting and staging all materials, to ensure a smooth application before the resin cures.1:40 Once cured, the repairs are ground flat with an 8-inch grinder and finished with multiple applications of gel coat filler, which is sanded between coats to achieve a fair surface.8:34 Proper preparation and staging of materials minimize the risk of air bubbles and ensure structural strength during the lamination process.6:33
