my attempt at a spray booth (knockdown type)

here is my attempt at setting up a knockdown PCV spray booth that I can use inside or outside (hopefully)on a concrete pad. excuse the jammed up mess(happens when You have a 11x40 section of the garage under reconstruction from tree damage. large tree,thin metal, guess which one won)
so now I've got 42x40 and a second floor of the one section15x20 worth of stuff jammed into 30x40. it don't FIT! I have to find some place in the Florida area that can get me some red iron purlins and girts(sp) soon, it bent them up pretty bad.

I have in the past used just about every process (wood & drywall was the best but I needed the room again)
rented a booth (worked perfectly, but had to wait for the date and it put me behind on the build) Expensive compared to other methods

wood and plastic sheeting (worked but I used the wood for something else)

big tent (worked but didn't seal worth a darn)

cargo container (filled it up with junk as soon as I finished spraying) bout killed myself , didn't have good ventilation

and got tired of paying for wood that I eventually reuse for other things and have to go out and buy the stuff again.
I don't mind getting the plastic again just to make sure nothing comes off and falls into the paint.
I'm just setting it up now and haven't decided if it'll be all bolt together or glued in the walls and bolted to the top and end sections. I'm leaning towards gluing the sides. that way I can knock it down and slide the walls outside ,
the pluses to me are.
1 use it anytime I need to
2 and it won't cost me a fortune in replacing the wood( ain't none) because I used it or it rotted
3 it'll be able to knock down (less space used)
4 it might work outside too
5 cheaper than renting a booth multiple times and waiting to use it
6 easy to change thing so that anything I forgot to do can be fixed easily.

the minuses are
1 I have to figure out how to do it correctly and seal it using foam at junctions.
2 higher initial cost than a wood tear down
3 almost the cost of renting
4 I will replace plastic depending on usage for a reoccuring cost.


I have one side of the (4 per door) door mocked up for the exhaust it should be 8 20x25 painters filters,(I'm using house filters to size them for now and have a space that I'll have to plastic sheet in between em) but the intake hasn't been done yet. should be the same size (8 20x25's in a square pattern centered) I have a LARGE (bout 3 foot blades) exhaust fan that's belt driven that I can gear down to do a slower flow.
what do ya think so far.

on the 45 angles I'm mounting 2 4ft lights each section (if i can figuer out how to mount the ones near the doors.

the double pipes that you see will get a T put in between 2 4ft light in each section. should have 8 on the sides and 2 on the front.

filters worked out nice by cutting a 3/4 pvc pipe down15mm, it seemed to catch the filters and hold then pretty good, but they will be taped in to hold them solid.
