last year I successfully relaminted small area in deck by drilling 3/8 holes,squirting west system epoxy,& appling pressure. This area was able to bond great to embedded wood.
Now I have an area(s) in between wood. I know west system is supierior in bonding but im not sold on the fact that it is needed to bond to the enclosed foam. Its a 63 Sakonnett and any bond made with this foam can only be as strong as the foam?
Im curious if anyone has attempeted this repair with a less volatile product, one that wont heat up under surface and may have better properties for filling these gaps between the deck (only 1/8 or 1/4 inch deep and about 2 feet long by 6 inches wide)
Seems to me that the deck would eventually tear away from the foam after west system application.Would like to know if alternative product has be squirted inside to better fill the gap and still provide enough bonding strength to adhere to the foam.

I was under the impression that you are supposed to get as thin a layer of epoxy as possible and try to 'relaminate the floor' as opposed to 'fill the gap'. I have heard that if you get the west system spread thin enough and use the medium speed hardener heat is not a problem and it works well.

And in anycase - if it delaminates again, you dont have nearly as much epoxy under there if you just had a thin layer to start with.

that is a good point, I just didnt know if anyone had tried to squirt through the deck with another material to a.fill the gap &b. bond deck and foam together but your point makes since about not building up layer.

I would contact BW customer service for help on your problem. I know that when delamination occurs under smooth skin areas, they recommend cutting out the bad glass altogether, and laying in new glass matting, which will bond to the repaired or replaced foam. Don't know what would be recommended under non-skid areas.

This does not answer the question about alternatives to West System, but there is a response from Boston Whaler on the subject of delamination. They are talking about a side wall and not a deck but the procedure should be about the same.
