In the December, 2001 issue of Popular Woodworking (issue # 125) I wrote about how to construct a simple but safe home spray booth. This article was reproduced in my book, “Flexner on Finishing.”
But what if you have more space, do a lot of finishing and would like to have something more like what professionals use but still don’t want to devote that much space? This sounds pretty much like my situation when I moved my shop home from the 3,000 sq. ft. building I had been renting.
The requirements for a spray booth are as follows:
- Steel construction for fire safety.
- Filters to catch and hold overspray before it gets to the fan.
- A chamber, called a plenum, for collecting the air to be exhausted. This exhaust chamber makes it possible for air to be drawn uniformly through a much larger square footage of filters than the simple diameter of the fan.
