Method of treating fiberglass boat hulls to repair, prevent and retard blisters

摘要

A solution or dispersion of polystyrene is used to treat the submergible surfaces of fiberglass boat hulls to prevent or alleviate blistering. With newly constructed fiberglass hulls polystyrene paint is applied either directly to the fiberglass surfaces or to a gelcoat protective surface applied over fiberglass. In the case of existing fiberglass hulls on which blisters have formed, the blisters are excised, filled with an epoxy resin or other fairing compound and ground smooth. Polystyrene paint is applied either to the blistered areas or larger areas after sanding.
