We're the fans cold or cold where you were doing it ?
Nope. Cans were sitting on the basement floor for days. In-floor radiant heat @70F air temp (warmer on the floor).
The application was on the south side of the house (interior) and I applied it on an afternoon in the upper 60’s. It was warmer inside since the joist bays were directly above the boiler, so that area never cooled off at night.
I’d bet that it was just a bad lot, but both cans in pack sucked equally. I had a can of their big gap filler and finished the job with that. That can worked perfectly.
When I ordered from Lowe’s, they shipped the product to me via ups. For me, not worth driving over an hour to take them back for refund or exchange. It’s a shame as I really wanted this to work as advertised. I’ve moved on.
Maybe I’d try it again if Menards or Home Depot ever starts carrying it. Either store is a 10 minute drive so an exchange or refund would have been easier. Lesson learned.
