Exterior Foam Concrete Dome
Currently building a monolitic concrete dome in Florida, 30 feet in diameter 16 feet high.
I intend to spray 2 to 3 inches of 2.5 lb closed cell foam over the exterior.
Plans call for a split ductless AC system
Knowing this scenario any comments?

We have had a monolithic concrete dome since 1995, and the foam was covered on the outside by a thick vinyl outer shell, which prevents sun from breaking down the foam. Works great. Ours is a bit different, covered by earth beyond the vinyl.

How can I email you a picture of a small machine I want you to look at. Let me know if you have seen one before?

My goal on this project is to not only protect the foam but whatever is used will also serve as a cosmetic finish.
Will probably use the fiber mesh and stucco
