When installing a floor like that, we would check the floor with a 6 or 8 ft straight edge from the first row to the doorway. Nailing a temporary board across the doorway at the correct height and checking each row helps keep the floor as flat as possible. We've done a few floors that way in the past. Kind of a pain but it does work well. He said 6 to 7 bucks a sq ft, better triple that in today's world.
I agree about the mud being a little dry but wetter mud would be harder to beat into. He also said it was 3 to 1. Nice video, thanks for sharing. I like seeing that type work
