Thanks for the tips.

I was thinking more about a good way to apply it, so that you get the right lichen look. I know a few ways to get the right general texture. I've made a few dioramas in my youth, but never really anything in the scale 1:1. Except for a couple of unsatisfactory projects.

There's also a great tutorial on making fake rocks at:

Build your own fake concrete rock

It's got step-by-step instructions on how to make a mold, mix the concrete, etc.
