The main thing that got done was that the drywall crew sprayed a texture onto my ceilings, my garage walls, and inside my closets. this is a "knockdown" ceiling texture, so the height of it is very shallow, maybe 1/16 inch or so. It's a bit larger and more random of a pattern than I've seen before, with a fair bit of open space in it, but I like it just fine. It will add a good deal of visual interest to the ceilings wihtout drawing attention to itself, and it won't be a maintenance headache like a "popcorn" ceiling texture.

They masked pretty well, but the overspray from this stuff is everywhere. It should sand smooth without any issues, it appears that they used the same drywall mud to do this as to mud and tape the joints. Anyhow, I'm pretty pleased with having this in the garage, it looks dynamite already.
