O que este vídeo aborda
A pontoon hull with a through-hole that cannot be accessed from inside receives a blind patch repair using a cardboard-backed fiberglass backer.0:06 Kent cuts a piece of woven roving — fiberglass cloth works equally — folds it around a cardboard form small enough to pass through the hole, then threads strings through it so the patch can be pulled flat against the interior hull surface once inserted.0:06 Total Boat Fixo Pro thickened epoxy adhesive is mixed, applied to the patch, and also run as a ring around the inside edge of the hole.0:34 The assembly heats rapidly from the exothermic cure reaction, requiring quick placement.1:29 Strings are held taut against the hull exterior with a paint stick until the epoxy sets.1:39 Once the backer cures, successive layers of fiberglass cloth are laminated into the hole, built up to just below the original hull thickness, leaving room for a final gel coat layer.1:08 A completed example of the same repair on an adjacent hole on the same pontoon is shown as a reference.1:46
