Fig. 11 The type of resin to use for the initial fiberglass planking coating is critical as well as the method of application. See notes elsewhere on the proper resin specification for this initial coating. A brush or roller can be used to apply the resin. Work from high areas to lower areas, using only enough resin as is required to coat the surface. It is not necessary nor desirable to completely saturate the material at this point because more resin will be applied to the inside after the hull is righted to complete the saturation. Any excess resin should be squeegeed off and discarded in order to avoid a brittle resin rich lay-up.
Fig. 12 After applying the resin and allowing it to cure, the surface should be lightly sanded down to remove any protruding nubs and ridges. It is also desirable to wipe the surface down with solvent to remove any dust or dirt prior to making the lay-up. Always wear a mask when sanding. In some cases, the joints along the stem and keel will be reinforced with additional fiberglass laminate prior to applying the hull lay-up. Continue |
