Technical question on expanding foam, particularly Great Stuff--
Let's say you want something with a foam exterior but you don't want the lines a can of Great Stuff gives.
Can you smooth it with a plastic knife while it's still curing? What sort of textures can you achieve with wet Great Stuff? Can it be smeared around while wet?
Do you have to wait until it dries, then carve or sculpt it then with a sharp edge or a toothed blade?
I'm hoping for an irregular rocky surface, and this particular project needs to be completely hollow and riddled with cracks and holes, so I can't make paper mache or paper-and-tape rocks. I'll use paper mache clay if I must, but I'd rather avoid it.
