I’m planning on leaving my open ceiling exposed and install white metal on the sidewalls of my new shop. I’m going to paint the ceiling first. What’s a good paint to use? The spray foam guy will have the floor and windows covered so I don’t think the expensive paint that dries before it falls(or whatever that is) will be required. Also, suggestion on how much paint will it take to do a 40x60 ceiling and what sprayer to rent? I’ll have a scissor lift there

Thats a good question, I would think that latex would be better than paint that take a solvent to thin which I would think that it would damage the spray foam. But, I am guessing and because I am also thinking about expose spray foam.

Can you have the foam guy coat it?

They should have a fire resistant paint. This is usually required when the foam is left exposed.

I painted the entire inside (ceiling & walls) of a large pole barn for a friend 10 years ago. I used Sherwin WIlliams exterior Super Paint and it has held up on the spray foam just fine. I used exterior paint just to be safe as the barn was not heated all the time.

I painted my foam with Sherwin Williams acrylic dryfall paint. I had a scissor lift on site, and my father in law has a sprayer that I borrowed.

As far as renting the sprayer, he has THIS Harbor Freight airless sprayer and it worked great! For $200 (I think they're on clearance and a new model is out) you can probably own it for less than you can rent it to do the entire job.

I will say that even though the painting was relatively easy, it took a lot longer than I was expecting... Just like most things on this project, haha!

I went with Flat Black like you see in a lot of renovated industrial, turned commercial buildings, restaurants etc. It's not fire resistant or anything, but I like the way it turned out and it was relatively easy (and inexpensive) compared to a lot of the other options.

It also makes future changes to wiring, lighting, ductwork, etc., easy since the ceiling is basically exposed.
