Project: Clean Air Booth – Act 1

Time for a project. It’s been a very busy start to the new year and with the work orders increasing, a clean booth for refinishing is next on the list of shop additions.

RetroFIX
Built as a pole barn for housing a motorhome and a couple of cars, the interior of the shop was never finished. For additional storage, a loft above the north side was constructed using poles for cross-beams, laid along some heavy 4″ angle.

Working in a limited space, the booth area will need to be convertible in order to provide an area for other “clean” tasks. So, a couple of the walls will be of the curtain variety, with a ceiling and north wall being the major items needed to construct. The build plan was to lay wooden beams perpendicular to the existing loft poles and run 2×4 studs off the beams, clearing the poles. The studs would provide level, drywall screw friendly anchor points for the ceiling and the beams will provide support for the loft floor.

I got lucky framing the ceiling around the existing beams and had no interference with 16″ centers. At this point the frame was floating, which made it nice to move and square up to the building, but it would need to be leveled and secured…

Shimmed and Strapped
…which was done using shims in the low spots and 2″ conduit straps to anchor it down.

Some drywall going up for the new room. Don’t let the deadman fool you, this piece of drywall ended up falling to its demise after a poorly calculated move on my part.

money well spent
Luckily for the drywall, my head broke the majority of its fall, but the panel was lost as a whole.

first 8'
A lesson learned and work continued. With the first 8′ hung, the next thing to do was incorporate intake air ducting. With the booth providing a side down-draft of air travel, the overhead framing would need to modified to fit the filters.

Intake frames
After much internal conflict, the intake filter sizes were chosen and the framing for the ducts were built. The two frames are 20″ x 60″ to accommodate four 20″ x 30″ filters, with the option of six 20″ x 20″ filters with a simple adjustment. The new frames were assembled and lifted into place…

…then drywalled up. By luck, the broken sheet had just enough width containing a beveled edge to supply the last piece of the ceiling.

Here’s a shot of the whole ceiling. I’m content with the results, seeing this was my first drywall experience other than the occasional home repair. Next up is the north wall, which will require relocating the window and east door. Then on to a very cool booth exhaust system I have planned…
