Questions about sculpting and hardening foam.


New Member
Hey guys and gals,

A friend of mine has just finishing purchasing a house with an unfinished basement. Upon seeing my basement, and home theater get up, he really wants to go overboard on his.

I'll cut right to the chase...

He is a massive superman fan and has quite the collection. He wants to deck out his home theater so that it looks similar to the Fortress of Solitude. I told him it could be done, by just sculpting some large foam blocks into the fortress crystal patterns and then mounting them on a wall. I also remember seeing some kind of coating you can put on the foam to make it harder (I think I saw this on Monster House or something).

Two main questions for you folks.

1. Where can I get large foam blocks to sculpt (or I suspect it would be cheaper to just make the foam in trash cans or something and sculpt from there), or what kind of foam would be most suited to this kind of venture.

2. Is there such a substance that we can put over the foam to "harden" it and give it some staying power. (I'm suspecting that fiberglass might be the best option, but that would be a lot of fiberglass by hand).

Thanks in advance.
