How much will this 16Oz bottle coat?

I had it for a whole 24"x 156" roll. Probably needed two bottles for that.

Easy to use, goes a long way

Easy to mix. I’d certainly recommend using a hand spray bottle to apply it rather than a brush. It seems to rigidise my thermal kiln blanket well and is economical.
