Help with foredeck delamination repair

[cyrus jordan]

Typhoon weekender with delaminated foredeck, no rot. Test holes revealed that the bottom skin had separated from the core. I drilled a pattern of holes and put in some resin. Some resin leaked out from the side of the lower skin into the cabin. Cleaned it up with resin cleaner, no damage done, but I'm not sure why this happened.

Is the bottom skin and the cabin ceiling the same piece or is the cabin roof applied under the bottom skin of the foredeck?

Anyone had this happen to them?

My hunch is that the delamination went all the way out to the edge of the foredeck allowing the resin to leak out at a seam between the lower skin and the core. Hopefully, yesterday's resin will have occluded to path of egress, so tonight's resin infusion will stay where I hope it will.

Interested in hearing from someone who knows what the internal anatomy of the foredeck is.

Thanks

I have recently inspected a fair amount of my deck's core. I found the aft deck very rotten due to the number of fittings, the fore deck was rotten and wet around the cleat only. My cabin ceiling is the lower skin of the deck. It is an early model and looks like paint over glass mat. I have looked in some portholes at the yard and it looks like newer ones have either a liner, or at least gelcoat on the inside ceiling. I have found edges of the cored area of deck do not have much glass on the inner surface; no wonder the resin leaked out here. Good luck.

Thanks.

I think that my '74 #672 has some sort of inner liner that they attached to the bottom skin. the resin apparently leaked from the sides of the core, onto this inner liner and then out. The inner liner has a downward curving lip (probably so that people couldn't look at the messy unfinished sides of the core) that doesn't let me see what I want to see.

About one pint of the first three that I put in leaked out. Inspite of this, most of the delamination has been repaired. There is still one small area where the holes are not filled. Tonight, I'll try to put some more in. I've hung egg cartoons inside to catch anything that drips out.

Thanks again.
