I admit I was a little skeptical, but this worked great! My application was on a 30 year old uninsulated sub floor. It was only about 20 inches above the soil line so I was unsure if I could apply it correctly with the tools provided, however it worked great!

Insulating my attic and tried a couple of different spray foam products, but nothing had the coverage and expansion as this product. After trying the rest, I stuck with the best, I mean Beest.

Easy to set the supplied sprayer and spray the foam into hard to reach corners i got around a 3-1/2 inch build up of foam in 1.00" increments letting it cure for 30 min each inch sprayed. Great product and easy to use.
