   I spray outside all the time, and don't use a booth.  I have a covered 20' X 20' carport, and just lay down some painters drops on the concrete floor if I'm spraying clear coats.  If I'm spraying  color, I use my carrages, and take the pieces out into my gravel drive and shoot them there.  Just rake the gravel to cover the overspray.  Now about the wind.....

   Whatever solution people offer, I'd like to hear it too...

   I've got the same problem...

   Measure it with a micrometer, mark it with chalk, cut it with an ax.

   I just converted my shop to a spray booth for the weekend. I use a conversion HVLP gun. This type of gun does not fill the air and everything in the shop with material like an old fashioned gun would. I simply build walls by stapling poly to a 1x2 and attaching it to the ceiling. I make the U shaped booth around a window, place an old box fan in it with some furnace filters taped to it and wear a proper respirator. This weekend, I'm just spraying oil based paint. If I spray more volitile materials like 2K urethane, I'm more careful about ignition sources. The HVLP just doesn't create the cloud that may cause explosions. I'm usually not spraying vast quantities, maybe a half cup at most will do a large cabinet. It can be difficult to spray outside, little bugs appear from nowhere. Be sensible and get as much ventilation as possible. The poly sheeting will shed dried coatings later so I just throw it out when finished.

   Beat it to fit / Paint it to match

   I made a spray booth from furring strips and polyethlene . I stapled the poly to 2'-0"x 7'-0" furring strips. Panels are connected with duct tape. I stapled the edges of the duct tape so they won't pull apart. The tape acts as a hinge. The setup has worked well for me.I'm looking for a safe way to exhaust the fumes. Explosion proof fans are expensive so I try only to use non flammable finishes.

   I appreciate your responses everyone. Good ideas. Sancho Ron, thanks for the reference to Jeff Jewitt's book. I'm sheepishly admitting it's in my library, so I pulled it out and checked out the spray booth plans. Looks like something I can adapt pretty easily for what I need. Man, I guess I should maybe start actually reading all these woodworking books I've bought.

   A freind of mine was interested in the spray booth. So I called jeff and asked him where he could get the fan for it.

   Jeff is one great guy. So if you have any questions about how to adapt  it to your particular needs call him.. He is a nice friendly guy who gives his info away...

   Last winter, I had to spray a finish for a crib I was building. I cleared an area in my basement shop near a window, and made a booth out of sheets of foil faced insulation panels. I hinged the panels with duct tape, and in the "back" panel, I cut an opening to recieve a large furnace filter, I then fastened a second piece of foam to the back, with a slightly smaller opening. This created a rabbet to hold the filter. I then built a large plenum box that attached to the back of the filter opening with adhesive backed velcro. To the plenum box I attached hvac fittings I found at Home Depot that transition from a 8" square with tabs on it to a standard 8" round elbow.

   I then unhooked the motor/impeller assembly from my delta dust collector, and used 8" flexible aluminum duct to connect the filter box to the impeller.  On the exhaust side, I made a panel out of 2" pink styro that pressed into the basement window, to which I attached another one of those transition elbows and flexible ducting.

   the whole works folds in on itself, and sores in the rafters of the garage.

   Make sure if you try this to open another window when the fan is running. I forgot the second time I used it, and the vacuum was so great, it sucked furnace exhaust back down the chimney, and tripped the CO sensor in the furnace!

   To fashion a "booth" inside my shop, I selected an outside wall with window/door, then for the three other walls, I fastened 1 x 1 x 2" strips to the ceiling above the "corners", using 10' wide x 30' poly from Walmart ($3.69), and temporarily fastened the poly with clothespin style spring clamps to the blocks, letting in drape down to the floor.  Any machinery inside this "room" is covered with poly and often used to support small projects on lazy-susan turntables.  When I'm done, I fold up the poly for use next time.  I usually cover the floor when spraying colors or varnish, but lacquer is usually settles as dust.

   Of course, one must wear a respirator, which, when not in use, is kept in a plastic zip-lock bag, otherwise it will continue to absorb odors in storage until it is consumed/disfunctional. (That is, a charcoal cartridge type.)

   I made one out of pvc pipe years ago and have used it less than 5 times. It 's a giant tinket toy thing that I can setup in the garage and cover with plastic. It'll bet a real challenge to put it together again. But the bottom line is that it was real cheap and quick to build. I think I actually drew a real rough sketch of what I wanted so I had some idea of what to buy at the homeowners hell store. it wasn't real sturdy buts suits my purposes since I use it so infrequently.

   Safety tip o' the day - Always keep your three good fingers away from the blade and remember to wear a safety monocle over your one good eye.

   If your shop has a garage door, you could make roll up curtains that would wall off the main areas of your shop.  you can use thick poly attached to the roof with 2x2 to weight the bottom.  when i was in the same situation i use to spend an hour cleaning my shop to do 5 minutes of spraying.  once you unroll your curtains, use a blower to get as much dust out as you can ensuring any where the overspray might hit will not kick up dust.  when i spray cars i wet the floor too so as im walking around in and out of the clean area i dont kick up dust.Tmaxxx
