Divinycell Core.

[Xyacht]

Unlike the many posts about recoring "balsa" after water intrussion, this is a question concerning honeycomb divinycell. I have a 1985 X-yacht which began to leak from the Hatchboard garage. The water eventually found its way through the core down to a hole in the bottom of the deck over the galley sink. I have finally found the leak on top of the deck and repaired this with expoxy. However a small amonunt of liquid, maybe a tea spoon /week continue to seep out above the galley. At which point do I just fill the whole an forget about it.

Thanks,

The problem with foam cores, like Divinylcell and Airex, is that they can allow water to migrate long distances, and delaminate rather large areas of composite after relatively little water intrusion, especially if the bonding between the fiberglass skins and the core was not done properly.

Are you sure that you've actually sealed the opening that is feeding the galley opening??
