I helped a friend build a yurt out of 2" styro boards. The structure was fine, but we found them almost impossible to tape. Nothing we tried would stick. This was in New Zealand; there may be better exotics around here, and I have had a suggestion from a scenic artist for a coating that might do the trick. But understand that it's a problem that needs to be solved.
Spray-coating them sounds like a fine application if you can get them to hold together long enough.
