I am wanting to make some foam walls and big things like boulders and a cave. what type of foam is cheap and works well for these aplications? I am going to put body parts and bones etc. into the walls also.

Will this be located inside? If so, I would use "Monster Mud" it's a mixture of 1 part latex paint, 5 parts dry wall joint compound. It's used similar to paper mache but instead of newspaper you use burlap (or any fabric for that matter.) The haunt I used to work at made a huge cave out of the stuff and it looked great.

Good luck!

I would use EPS foam (white poly styrene) Its great for that.

The cave and wall's will be inside, but the big rocks (4ftt.) and colums will be outside.

Outside I cover my stuff with a layer of Snowseal or any liquid roofing sealer before the paint.
