Closed cell spray foam not sticking to concrete walls
I just had a company come out to apply 3" closed cell spray foam to our basement. The basement has been demoed so it is just concrete walls (with some nails in place that were used to adhere the fake wood paneling previously).
The guys applied 2" of foam to the concrete but, after curing, it cracked and was easily popped off the walls. The only place it stuck was near the water meter and pipes. They tried a thinner layer to see if that would stuck without success. The crew told me the walls were reading 43 degrees F right now (we just got 4" of snow last night) and they had me turn off the furnace while they worked).
The plan now is to frame up the basement leaving about an inch between the concrete and wood frame then spray foam and allow the frames to hold the foam in place.
Wondering if anyone has experienced this before or has thoughts as to why it is not sticking to the concrete. Any downside to framing first?
