Osmosis Repair on a Fibreglass Hull

This video shows the repair process of osmosis blisters on fibreglass hulls and prevention from further blistering. Some of the products we use may only be available in Canada due to different environmental regulations in different countries. If you are repairing osmosis on your boat ideally you want to keep the boat out of the water for as long as possible to dry the hull out before applying epoxy. This could take many months. Epoxy will trap any remaining moisture in the hull.
