Agreeing with Sjbonnar on this one! Ive used PVA glue to seal foam lots of times and never had any problems =) As pointed out just make sure to do a test beforehand.

Sorry to hijack the thread but anyone know any good places to buy craft foam in big sheets???
If you happen to have a Hobbycraft store near you they sell it in there in A3 sized sheets in various colours, it was about 79p a sheet when I got mine a few weeks back =)
You should be able to find it online though, I used to buy mine from here
http://www.fredaldous.co.uk/search.cgi?action=search&query=foam&level2_id=269 before I found Hobbycraft =) Just depends on which size you need I guess, Ive never been able to find it bigger than A3 myself.
Or buy it from Pez xP Ive also known a couple of people to buy camping mats and cut them up too but obviously they weren't designed for that use so will be a bit different to actual 'craft foam' hope this helps =)
