If you can heat your shop or your finishing space, that’s a good idea.

Two points to keep in mind:

1.) You can do finishing in the cold. Oil based varnishes and shellac will still cure/dry. But they will take much longer. I’ve also had reasonably good luck brushing lacquer in the freezing cold (note I said brushing, not spraying). Once again, it will take much longer to dry. Water base finishes and oils like BLO and danish oil never worked for me below around 60 degrees.

2.) Oil based finishes like poly and Waterlox cure by reaction with oxygen. So make sure there is enough air circulation so they don’t get oxygen starved.
