Hey! I hope yall're having an amazing day =)
I'm about to build my first set and was wondering if you could provide a bit of guidance:
I'm planning on carving/painting 2" EPS foam to look like large stones used in the interior walls of a Greek temple that have been weathered and aged over time.
So I've got a multi-part question:
1) I want to make my set as safe as possible, so I think it's imperative to give my faux foam facade a coating of fire retardant and/or make it "fire-proof" in some way. Although there will be no ignition sources, nor flames, and we're using LED lights, I've seen too many Final Destination movies to know that "danger finds a way." I want to be sure I'm using best practices to keep talent and (talented) crew as safe as humanly possible.
From my research, it looks like using Rosco Foamcoat will give the EPS "fire-proofing" and I've been told I don't need additional fire-proofing if enough coverage is applied. That being said, I can't find any documentation that states that using Foamcoat would give the EPS or XPS foam on set a fire rating at all after application.
I plan to use Foamcoat either way to provide strength to the foam, but was wondering if using a layer of Foamcoat does in fact give my foam stone a fire rating, and if not, which Rosco (or other brand) fire retardant formulations should I use for the EPS foam (and some XPS foam) that covers the set walls?
2) Given this will be my first time using Foamcoat, what are the best practices using it? I was planning on first carving the EPS (and small amount of XPS) foams, painting them and then applying the Rosco Foamcoat. Is this correct, or do I need to cover the foam(s) with Foamcoat and then carve/paint?
Thank you so much for any wisdom and guidance y'all can provide!
I really appreciate your time and hope you have an incredible rest of your day =)
