I need help finding which kind of glue i should use for gluing fohme board.

pva glue aka elmers glue or craft glue. it works the best in terms of polysterene or foam.

Thanks

i've used wood glue to put big pieces together but for everything else i like to use Aleenes tacky glue instead of reg pva glue, i think it holds up better and if that wont due then break out the hott glue gun. but then again it depends on what ur doing as to what u should use nothing will work on every job if so there wouldnt be so many diff kinds on the market but go pay the extra buck for the aleenes, any good craft store or section should have it, its in a gold bottle

yeah wood glue is good to forgot to say. reason being it goes through the porus surface of foam and holds it together better. This is also how it binds wood being that wood is a porus material
