Should all windows be left open during refinishing?

Q: I am scheduled to have hardwoods flooring stained and 1 coat of sealer tomorrow, but it is supposed to be only 40 degrees and rain, maybe ice. I understand that all windows should be left open. Do I need to reschedule for a warmer day in TX?

A: I disagree that all the windows should be left open regardless of the temperature. When applying any coating one thing that can really mess up the job is to have air moving across the coating before it has had time to flow out and set up.

You will need to have the house well above 40 degrees, and close to 70F would be more ideal. If humidity in the home is high, running a dehumidifier should help with that.
