Lots of the pros use an airless sprayer to cover 15-20 sq. ft. at a time and then go back over the wet stain with a stain brush to smooth it out. I have yet to tackle my fence, but that's how I intend to do it. If you are using a different stain than the one that is currently on the deck, you do need to get the old stuff completely off, first. The quality of the prep job is more important than the quality of the stain application.
