I'm going to start gluing my extruded foam to my benchwork but I had a question. I was reading about using Gorilla Glue and I recall something about spraying the foam (or was it the glue) with water before gluing in place. I can't recall what was the best process to get the glue to work with the foam. 

Any links to articles about this or information on how you did it would be great.

Thank you.
