How do you fix delamination on an area of the deck that does not have wood. Its the curved area just below the anchor locker on the 16' montauk, 1974 year.
Thanks.

I was just reading some West Epoxy literature so I know an answer! Of course there's probably more than one way to do this. They recommend that you drill lots of small holes in the deck and a little beyond the delaminated area and inject epoxy in the holes and then put a weight on the area til it cures. West Epoxy is incredibly easy to use and it is pretty easy to suck it up into their syringe. Just make very small batches until you get the hang of it. The directions are in the pamplet that comes with their maxi repair kit. You can also try searching on youtube for videos of the process.

Sounds like a starting point, thanks.

Just drilled the holes and filled with epoxy, now I realize how hard it is to put pressure in this area. Its curved so I can't get any real pressure on it. I suppose sand bags would do it.

Ok, I am getting frustrated. There are holes that don't seem to fill up. I can't force more epoxy in with the syringe, but as it sits, I see small air bubbles come out. I know this is filling the void better, but its getting annoying with only a very little at a time making it in the void. This is the forth time I have had to put more epoxy in some of the holes. I have though of drilling the hole a little larger and stuffing fiberglass and epoxy in it. Does this sound like a good idea?

Pictures would help us understand the problem a little better slo post some if you can. You may have cut the bad section out and rebuild it

I am currently fixing a similar issue on my 15' sport around the norman pin. I used 1/4" diameter holes and a large syringe from MAS Epoxy. I added some milled fiber to the epoxy for 2 reasons. 1. to give the epoxy some tension strength. 2. to cut the viscosity of the epoxy. I believe you still want the epoxy to be fluid enough so it can work easily into all of the crevases in the foam and also bond to the exposed surface of the hull below. It has worked for me so far.

I think adding the fiber to the epoxy is the way to go.

Sometimes the big problem of getting the epoxy in the hole is that when you shove the syringe in, it bottoms out against the foam blocking the needle.

I think the air pockets are pretty small and the viscosity of the epoxy just needs time to settle in. Its starting to get pretty old though.

Have read a couple recent discussions on fixing screw holes and attaching hardware. Epoxy and Gorilla Glue were both mentioned. Several people mentioned the Gorilla Glue expxands. Has any body used it fix soft spots?

I have not used it to fix soft spots, but I can gurantee you that it does expand BIGTIME! You might experiment some with it and see what happens. Makes sense that it would work if you could get it into the troubled spots

ioptfm,
Appreciate the reply, that's what I've read about it expanding and thought why wouldn't it work. Will have to pick some up and experiment off the boat first. After doing some reading last night I think my Outrage has the typical foam block soft spots along the outer deck. At least after reading that it eased my mind a bit about whats going on down there.

Why not just grind or cut out the delaminated section and refiberglass/fill and then sand smooth and level with surrounding area. Worked for me. Len - shopj@metrocast.net
