Spray foam fire-retardant painting
Recently I had my cellar a crawl space professionally sprayed with closed cell foam. The company was supposed to return to spray on fire-retardant paint. The crawl space is difficult to work in and they company has offered me several hundred dollars discount to leave it unpainted. They tell me that there is actually no requirement for the fire retardant paint in a crawl space, and that because there is no source of ignition in the crawl space, so it is safe. There is a living space directly above the crawl space. The fellow I spoke with said that in his own house there is a crawl space which he had foamed and that he did not have the fire-retardant foam done there.
Another wrinkle is that after the foam spraying, they said that they would be back the following day to paint, but there was a snowstorm and my recollection is that they put it off and was under the impression that, so far, none of the painting has been done. But when I spoke with the company representative today, he said that the foam in my cellar has already been painted, and that it is only the crawl space which needs to be done. So I am left uncertain as to whether he is correct, or if he is mistaken about the cellar having been painted. d
Here are my questions:
1. I would value any recommendation about the efficacy of leaving the crawl space foam unpainted and saving money, vs. painting it as a safety concern?
2. Is there something that I can observe which would confirm for me whether or not the foam spray in my cellar actually has been painted with fire-retardant paint?
Thanks in advance.
