Well I haven’t done too much other than re-arrange the the basement so that I could build my 11X22X9 ft paint booth. I used my upper floor joists liberally to hold onto the 2 mil plastic. I also used about 40 1X8 firing strips for the structure. And I will use probably 4 16X26 fan filters. The entire thing cost me about $100 to make which includes the fans and is almost completely sealed seams using packing tape. Oh yeah and it took 5 9X12 rolls of 2mil plastic to enclose. One of the features is that two of the panels are on hinges that fold up so that I can get things into the booth easily and also so that I can walk through when I am not using it.
