Teardrops n Tiny Travel Trailers

Looking in Bunnings I see we have Gorilla Glue which is pretty expensive. Is there anything else which works well for joining foam to foam? I tried a polyurethane construction adhesive and got a dissolved mess from the solvent, on test pieces.

For sticking the PMF we have good old waterproof PVA which is our version of Titebond 2 I think, so that's easy and cheap to get.
Cheers!

Z, the glue is the strongest part of the equation , the foam will most always fail first .. It’s the skin that keeps it all together … We use Titebond 2 for all our foam construction for many years now … No troubles !!!

note : T2 is not waterproof , but water resistant , So you’ll have to make provisions for keeping it dry from repetitive wettings ( like the morning dew) I recommend “drip edges” on all foamie trailers now and it really work to purpose …
