Probably too late for now but if you ever have a big spray foam job in the future :)
Best thing I found for spray foam is the reusable sprayer that you screw larger cans on.
It's soooo much better. I was sealing up everything I could in the basement before drywall went up.
We had a radon mitigation system installed after discovering ours was quite high. The guy that came had one of these guns to seal up all the cracks in the floor
Great stuff Pro 14. It's $60 bux but is a game changer. You can store the connected can on it for 30 days it says. They have a spray can of cleaner to clean it after your done.
