Default Proseal Drying time???

What have people seen for drying time on Proseal 890BII? I mixed 2 batchs last night out of a new can and 15hrs later it still is not set up? Anyone?

Default Drying out

Float, depends on temperature it is sitting in. The colder the slower. You said its 890B2? The 2 represents the working life in hours. Full cure at 70f should be somewhere in the neighborhood of 48 hours. Want to speed it up, put a heat lamp on it.

IIRC from reading the spec, the curing time roughly doubles for every 10 degree drop. At about 35-40 degrees (F) in my garage, it takes the better part of a week to cure.
