Don't use Titebond or any of the "white" glues. Because the foam is a closed cell foam there will be no air to get to the glue joint, thus a thourogh and fast curing is prefented, due to the lack of oxygen. You need a glue that does not attack foam and cures chemically. 30 min epoxy is good for small glue joint only not good for large areas. There is a foam "cement" made by Henkel (Germany) called UHU-Styropor or close to that. I used it in it works great. Works like "Contact Cement" I bought it in Europe on my last trip over there. But search the web, you might find it here in the States as well.
