Best adhesive between Minicell foam and a fiberglass hull

Advice
#1

Can someone tell me a good adhesive to use between minicell foam and the inside of a fiberglass kayak…its an expedition layup with the weave plainly visible…__

Can’t think of any reason not to use Weldwood contact cement (the original - not the water-based).

Yep, the red label…

Another vote for Weldwood, as above. Put a light coat on both the foam and the surface it goes onto.

Three votes

I agree with the others, but Lexel and any of the Goop products will work well too, though they take longer to cure.

And make sure it is aligned before you press.

On the foam, I find that two coats are necessary, as the first one will typically be absorbed (unless the dark skin is still on the foam). On non-porous surfaces like fiberglass a single coat is enough. Weldwood makes a gel version of their contact cement that’s often easier to use, since it won’t run or drip.

Contact Cement works well with minicell foam. Might want to test a small piece first - contact cement will dissolve some types of foam but it does not seem to dissolve the minicell I have used.
Another option is construction adhesive. I have used PL3X with good results.

Lexel glues. Best there is.
