About twenty guys from the tri-state area attended the six hour event, and here are the results. The Diamond interior finish plaster was applied right over the rough shotcrete, and provides a much more elderly and child-friendly finish down low.
This is what the surface looked like before we started -- it's pretty rough with sharp edges. You'll note the "test" patch of plaster where the bedroom closet will be.
Here's the same area at the end of the day. What a difference!
The all-volunteer crew did a great job, especially feathering around the openings.
Many, many thanks to all those who helped with the plaster! Your help saved countless hours on the project and it's very much appreciated. We'll see you soon for painting? :^)
