The entry doors pictured below received the same treatment as the garage doors in the previous post.
We stood the doors up to spray because catalyzed polyurethane is an oil based product (slow to dry) and will attract dust like a magnet. By standing them up with the fan positioned to pull air (and dust) away from the surface of the door we achieved a silky smooth finish.
We sprayed one side, let the doors dry a few hours, rehung them and did the other side the following day.
