I sometimes need to attach things to foam. In one instance it was a foam tombstone that I needed to attach to a thin plywood base, so it would stand up on a stage. Many years ago, I recall seeing someone use what I thought were drywall screws. But, that didn't hold at all on the polystyrene extruded foam board, I used for the tombstones. As I recall, what I saw many years ago was beaded EPS foam. So, perhaps that was the difference, but I didn't have any EPS foam on hand to test.
Perhaps there is a type of screw that has wider threads that would hold the foam better. Can anyone advise?
