Your Mileage May Vary...It picked up around 100 s.f. in 2 hours. BUT, it got the job done and the results look awesome, so I'm not complaining. I had to buy a specialized blade that I will most likely never use again for $11 and the rental was $25 for 4 hours but well worth it. Did I mention that sucker is heavy? I strained my back getting it out of the car and had a real tough time getting it back in.
Wednesday, I put primer over the areas with the new joint compound and I put caulk in the corners between the ceiling and the wall as well as a few other inside corners. Later that day, I put a coat of white ceiling paint on the ceiling. It was a Valspar product that goes on pink and dries to white (so you know which areas still need paint). A couple hours after that, I put the paint on the walls. Earthy Cane, here are pictures.
The unpainted areas are getting a tile backsplash.
