I've tried a lots of glue on foam. I found this glue while putting in a new bath floor. 800 by tarkett. I got it at a flooring store so I don't know who else carries it. It's a little salty [$40 a gal.] You had better have it where you want it because it ain't coming apart. It won't attack blue foam,dollartree,depron, or that dense white epp that my new tub was packaged with. It's a contact adhesive that works great on balsa also.
