Thanks, Jim. This information is very helpful!
I'm estimating that we'll need about 35 gallons of polyurethane to cover the
5.3k square feet of the whole space with two coats with a little bit of
buffer. We'll also need some plastic sheeting and lots of duct tape to build a
45'x14' wall as we do the space in sections.
I'll post a more thorough BOM to build@ here in a bit. Then I'll head to
discount builders to price things out.
