This is the only picture I have in the gallery here, with the stages I build for this work. These are in a hallway that was about 7 feet wide, with 11 foot ceilings. The height puts my head 1" below the ceiling, when I'm standing. They're just built with 2x4's, and plywood, or OSB deck. For that job, we built three, and jumped them down the 40' long hallway.
I use supplied air for doing any such dusty work.
In this picture, the original plaster wall was proud of the picture rails in some places, so we spaced them out to work better.
edited to add: You have not seen my methods on TV. Almost anything you've seen on TV is completely different than what I do.
