Hi All,
This spring I am hoping to work on a project with one of my classes where we design and build headstones for a future planned production of Edgar Lee Master's Spoon River Anthology. After some initial research, it seems like the best way to go about doing this is: use XPS rigid foram insulation board the create the headstones, use a dremel to router and carve out surface details, use a course drylok paint to give a rough texture/primed surface, and then paint weathering/aging.
I have used foam board before on small projects, but never anything so extensive. I want to make sure I get things right the first time, especially regarding flame retardants.
Foam: https://www.homedepot.com/p/Owens-C...oam-Board-Insulation-Sheathing-88WD/202085958
Drylok: https://www.homedepot.com/p/DRYLOK-1-gal-Gray-Masonry-Waterproofer-27613/100165469
Flamex: https://us.rosco.com/en/product/roscoflamex-pa
The question is: What would be the best flame retardant to apply to the foam? It seems like an additive to the drylok would probably work, but I've not been able to find any information. Any recommendations or leads would be greatly appreciated. Thanks!
Best,
Richard Buchanan
