Im going to be using Plast of Paris in my diorama. I plan on making the building out of it. My question is what does that stuff stick to? I was going to make a cheapo mold out of balsa wood and just pour the plaster into that and then scribe away at it to make the bricks and windows and what not. Ive never used plaster before so alittle help would be appreciated.

19Delta,

Your technique will work just fine. Plaster doesn't usually stick to wood. I have used it with heavy cardboard, latex ribber, wood, metal, plastalina and plastic. It never stuck to any of the products.
