temperature for polyurethane

Hi, I'm refinishing a table top using Minwax high gloss solvent based poly. I started the project in an unheated garage when temps were unusually mild- 60's. Temps have dropped, and I'm wondering how warm is HAS to be to still have this poly dry OK. I'm not concerned if drying takes a little longer. But this job is turning out very nicely, and I don't want to ruin it. I have a heated basement I can move in to, but it's dusty, and foot traffic is a problem. We're supposed to get a couple of days in the 50's soon, should I try it? Thanks, Steve

Usually you are safe if the temps are 50 and rising [quit if it's 55 and falling] The temp of the substrate [table] is important also. The poly will take longer to dry when it's cool which gives dust more chances to settle on the wet poly.
