What this video covers

To prepare for a two-day fiberglass training seminar at the Annapolis Boat Show, Andy of BoatworksToday fabricates 24 individual 12-by-16-inch fiberglass practice panels.1:54 He constructs a large 4-by-8-foot mold surface using a melamine-faced board over OSB, sealing the edges with tape to prevent resin bonding.2:30 To ensure clean release, he applies a base layer of waxed gel coat followed by a coat of polyvinyl alcohol (PVA).3:26 He uses 1808 biaxial fiberglass with a chop-strand backer and laminating polyester resin, applying three layers to achieve a final thickness of approximately 3 to 4 millimeters.8:08 The laminating resin allows for extended work time between layers, enabling him to pause production overnight without additional surface preparation.8:52 Once cured, the large sheet is cut into the final 24 panels, which are crated for shipment to Maryland.17:16 Using a multi-layered release system of wax and PVA ensures that fiberglass laminates separate cleanly from absorbent mold surfaces.
