In this video, you will be provided with a brief explanation oh fibreglass hull blisters and how to address them. A clear example can be seen of water permeating through the gel coat and into the fibreglass resulting in a dark weeping liquid from the substrate. This occurs when the resin of the underlying fibreglass begins to breakdown.
This method uses grinding to remove the blisters before later being filled with epoxy. It is notable the hull needs adequate time and high temperatures to allow the hull to dry before attempting to do such repairs. Notably in this demonstration, Steven finds an area that has come away from the fibreglass and needs to be completely cut out and filled.
