Very nice looking shop, it looks to be well thought out. What kind of paint did you use on the chippy board (osb)? I'm in the process of putting up the same stuff. I used Kilz oil primer, and rolled it on. A lot of work, I have 30 sheets of 4 X 9. I have to give it 2 or 3 coats just to make it look descent. I think I'm going with a water base for the top coat, probably a semi or high gloss. I like it bright in my work area.
With a nice size storage area, it should be easier to keep the shop area clean.
I used the Sherwin Williams for my floor paint, it was an industrial type that is suppose to be sold to professional use. I have one side of my barn done and it is slicker than goose ****, I think I'm going to throw some silica down on the other side?
Are you putting your air compressor in the storage area?
