Looking for some info on hardening styrofoam

I was wondering if someone could give me some tips on hardening styrofoam. I am sculpting some tree stumps for a project and i need to find a way to make it hard when im done so i can paint it and use it as a set piece. Any information would be appreciated, this is my first attempt.

latex paint or dry wall putty. Once sealed you can put anything you want on it (bondo, etc).

There is a huge pile of information of using styrofoam in the Materials and Processes Forum; it’s a more suitable place to find answers to these kind of questions.

:bulb: Do a search for foam, styrofoam, blue foam, etc.
