Anyone ever used a spray foam kit for a shop? I know l should probably pay a professional but I’m such cheap ass that I think I can do it cheaper myself. If you’ve used one of the kits which one and how’d it turn out? How thick did you go

Yep, it's also a really nasty messy operation. Let a pro handle it.
When I say shop it’s really just a pole barn with a dirt floor. So mess I’m not real scared of

I'll let you come practice on my garage and attic first. You supply the foam. I'll spring for Busch light.
I’ve also heard anything after 7” is a waste

I used to do it myself on every house I built. I can’t buy it as cheap as I can have it done now. It’s pretty easy to do though, if you do it yourself.
Like stated above, I can't buy it cheaper than I can have it done. It makes sense on a smaller area. It needs to be warm and you don't always get the advertised yield.
You don't want to breathe that stuff, it doesn't just cause cancer in California.

Get Danny to do it. Some things aren’t worth saving pennys on
I'm curious as to how it is easy to diy polyurethane spray foam. Where do you get the spray rig and enough material for a whole house? We use spray foam in all of our projects and the spray rigs are pretty involved. mtmuley

I used the kits that have two 5 gallon tanks. It comes with hoses to hook to both tanks and it mixes as you spray. You throw the tanks away when you’re done. When I built my personal home in 2020, the kits were $700 each. They have almost doubled since then and are not cost effective anymore.
How many square feet of coverage for 700 bucks? Our houses take multiple 55 gallon containers. mtmuley

600 square ft. If I remember correctly, my house took 7 or 8 of them. That was just the walls. I have ICF foam block in my crawl space and blow in in the attic.
@brockel, go the way I posted earlier. mtmuley

Menards has the small version on the shelf. It took two kits to just do my rim joists. Maybe 16” x 200’. They were 200 ish a kit back in 2018.

I did 1 1/2" of closed cell on all walls, complimented with batts. 1" spray in lid with blow in over top. I wanted tight but not too tight without an air exchange. Very efficient combination, I use maybe 200 gallons of LP each year to run furnace and kitchen oven/ range in 2600 sq ft. Wish I had done an air exchange now, if the house is left uninhabited for a week the air gets a little stale. Otherwise with normal use its fine.
Makes me wonder if a zip panel system installed correctly could offset closed cell, but the material/ labor adds up.

I should add that for the 2x6 walls it’s 2” of foam and 4” batts.
We have done full fill foam in 2x6 walls. Better make sure electrical, audio and video, any low voltage plus plumbing is in order. The 2 to 3 inch foam plus blown in or batts is a great way to go. mtmuley
