Polyurethane Curing Time?
What is the curing time for Polyurethane to harden enough so you can't dig into it with your fingernail? I'm having to wait on a test piece & would be nice to know if I'm looking at a few days or a few weeks as you all know, time & waiting can drive you crazy.

I'd give it at least two days better if you wait about four. The newer high solids polyurethanes seem to take longer to fully cure.

Not a chance
12 - 24 hours is plenty of time if the temp can be held in the ideal 78-82 degree range.
4 days.......please
