   but I find it a bit too flimsy..

   For water based just some plastic film on top and all sides to keep the dust out... I'd still use a respirator...

   With such a small workshop you will probably have problems with make-up air in the winter (assuming yo're not in either CA or FL). You need to give some consideration to ensuring that the ambient air temperature inside the shop/spray booth doesn't drop too much to avoid possible problems from chilling - I'm assuming that you're going to exhaust your booth out to outside.

   I have set-up a fold-away unit in our (small commercial) shop, but I couldn't use it last winter because our heating system system simply couldn't keep-up with the make-up air required. This winter we are going to add a large propane heater to msee if that will help.

   BTW I'd second the advice about ALWAYS wearing a proper respirator - who wants a lung caked with dried overspray?

   "Please respond ONLY if you have such a spray booth set-up in your workshop."

   When I HAD a small shop - does that qualify me? - I had a set-up similar to this (refer to link below) made from three sheets or rigid foam insulation. The funnel shape led to an exterior window with a capable exhaust fan (NOT a box fan). A no brainer to knock down and store and very, very inexpensive.

   Regards.

   Using 1.5 mill, clear poly ($5 roll for 10' x 25'), clipped (with closepin clamps) to short 3/4" square blocks screwed to the ceiling, to form a "room", with an opening to the outside (exhaust), I pressurize the shop with a box fan (intake).  Cover any machinery that ends up inside the "room" (usually working on tablesaw for a platform), and lazy-susan turntables.  Wear a respirator (when you can smell the finish while wearing one, you either have a bad fit, or the cartridges need replacing). 

   Once any perspiration from your breath has evaporated, store the idle respirator in a ziplock bag ... as it will continue to absorb undesirable contaminates from the air around it, eventually fully using it up.

   Dont get too fancy .... you can also cover the floor inside this makeshift room ... and make sure your automobiles are not just outside in the exhaust airstream ... or even anywhere close on cold days.  Extinguish any open flames before starting, but you may have to relight a heater once the fumes are gone ... to warm up the shop, before you turn it back off and resume spraying.

   You get the idea.  I've seen shops use those "third-hand" cabinet jacks to hold up the temporary walls.  Good Luck

   I use 1.25" PVC pipe to create the frame of my booth in my garage/shop.  The verticals are cut to 8' lengths for height and the laterals are 10'.  I use 90 degree elbows and tees to create the "box".  I use 9' wide poly to drape over the top and attach it with blue masking tape.  I then cover the perimeter with poly taped on with blue tape.  I overlap the poly in one of the corners for a door. 

   The floor is cover with 36" wide rows of scribing felt taped together with, you guessed it, blue tape.  The tape is easy to remove for re-using the felt for the next set-up. 

   I can build a 10'x10' booth, or 10'x20', or 20'x20'.  It takes about 30 minutes to erect or disassemble. 

   I spray enamel with an airless or polyurethane with an HVLP.  I always wear a mask, hood, goggles, gloves, and paint coveralls.  I have not needed to vent the booth so I can keep dirt, dust, and bugs out.
