I need to varnish (I have an oil-based polyurethane) some piece of furniture. I can't do this in my house, but I could do it in garage, however I worry about the temperature, obviously the garage is not that warm as inside the house (think of a typical North American house with attached garage, no heating, while outside is winter -18..-20C).
How would the varnish coats react to low temperatures? In other words, would it dry longer, would the drying under low temperatures produce some bumps/bubbles/etc.

I'm not sure what you're asking, exactly, but here are some suggestions based on my experience varnishing in a similar climate. The colder temps don't seem to have much effect on the quality of the finish.
