Yet another one from me as a side project I have a blank space I am turning into a black box space using curtains, as it is used for other classes as well, but primarily drama. I am using curtains to do this with velcro strips to "seal" the space when needed. My query is does anyone have a recommendation for a flame proofing spray they have used, and how much I'd need to coat 2 curtains at (wall lengths not curtain lengths) 9m and 2 at 12m, all 2.4m high
