Cosa tratta questo video
Johan continues the hull construction of a custom boat at Sunhill Farm, focusing on final fairing and the application of an initial barrier coat.0:21 After sanding the bottom section and transition areas, he applies a fairing compound consisting of epoxy, micro balloons, and colloidal silica to the keel pocket and marked low spots.10:09 To prepare for the barrier coat, he cleans the surface with a tack rag and alcohol.16:11 He mixes West System 105 epoxy with a barrier coat additive and white pigment, resulting in a light gray finish.18:03 Due to the cold temperatures, he uses a fast hardener and works in small batches to prevent premature curing.16:16 He applies the first layer to approximately 40 percent of the hull, specifically the bow section, to assess the fairness of the surface before the hull is flipped for further construction.19:52 The application of the base coat confirms that the previous longboard sanding achieved a fair, uniform surface.20:33
