Foamboard Glue

[nachoman]

I use Liquid Nails for Projects and have not noted the problem you experienced. The only drawback I've seen is that glue lines are a real...problem to hide, so I keep the glue as far away as possible from areas that will be sculpted later. I use pink and white insul foam. What sort of foam are you using..?

I have only been using blue foam - and only noticed the issue after knocking a small piece loose.
