So I had 8 doors that I needed to paint upstairs. Upon the recommendation from a professional door installer friend, I linked them together at the top and sprayed them.


In all, it took about 2 hours to set up the office in the new house into a spray booth, and about 30 minutes in all to put 3 light coats on the doors over 6 hours time.

I think I'll leave the spray booth in place until I get the doors for the ground floor. That worked pretty well.
