Working with foam

[Herc Driver]

I would suggest allowing the Gorilla Glue to dry overnight before putting any serious pressure on it. I've found it takes a few hours for the glue to set and mix with the small amount of water needed to start the reaction. It would probably be ok to handle after an hour or so...but the more time you give it the better from what I've found. Liquid Nails for Projects is also a good choice...and that stuff bonds fast and strong.
