Since I don’t have a dedicated finishing room, in which I can control air flow and quality, I always run into an issue when finishing a project. When I apply finish, I can’t do anything else in the shop until I’m done the finishing process, since I’d create way too much dust. Even if I abstain from other work, there’s always dust that creeps into the finish.
The solution is a dust free commercial finishing booth…but I’m not about to buy one. I do have space in the 900 sq ft garage with my wood shop so I thought I’d build a knock down booth using 1×4’s and 6 mil poly. Add a furnace blower and some furnace filters and I should be able to create a reasonably clean booth, and still be able to knock it down for storage when I’m not using it.
I decided to just use 1×4’s (for anyone in California, that’s the name of the lumber, not the dimension) to build a skeleton on which I can attach the 6 mil poly plastic (easily available here because that’s what all heated buildings use for vapour barrier.)
Here’s the Sketchup…it looks more like a prison cell.
My calculations show about 34 pcs of 8’ 1×4’s so I bought 40 pcs.
I decided to use half laps for joinery and Titebond III for weather resistance in case it gets left outside at any point.
