I have heard that expanding foam is sensitive to UV, so the top coat of concrete would be important. The burlap is also a good idea, it solves the problem I had with the foam going though the chicken wire, and taking about 2x as much foam as you'd need otherwise. I really like the organic look that the expanding foam gives for a volcano. Mine is just for indoors, built on a tomato cage with chicken wire. Red cellophane so the lights can be seen, with a fog machine on a 15 min timer. The lights were done with xmas lights, some on all the time, and some that flashed randomly, which gave it a great flickering effect, while still being on at some level all the time. Here's the start with just a little bit of foam (Might have been the first can) More foam And a big jump to done - I might have put more black paint on after. It did crack over the next few months, and now has some yellow foam color peeking out, I still like how it looks, and it's coming up on 2 years old. It's always inside though.
