Hi, I'm Stephen and I've just registered here. I've been making some diorama bases for the scene to be built on top of them. I've gone by the usual method. Get a compacted polystyrene base, surround it with wood, then begin layering the sculptamold on top of it. What I've noticed though, is that as the sculptamold has dried, the sculptamold has started coming away from the side wood and in some cases, I think the base has detached itself as well. Has anyone had that same experience at all? I'd love to be able to sell some of these eventually. Could someone tell me if there is anything I can do to stop the sculptamold pulling itself away from the side? Thank you.
