Defects and Damage
How is osmosis damage repaired on a hull?
The scope is set by depth rather than by the number of blisters. Confined to the gelcoat, it is surface work; once into the laminate, the gelcoat is peeled, the hull dried for months and an epoxy barrier applied — a difference of several multiples in cost.
Why it works this way
Skipping the drying stage is why some osmosis repairs return within a couple of seasons. Moisture values should be measured and recorded before the barrier goes on.
