I used to do that but I got tired of having the shrubbery covered in glaze.
So I built an outdoor spray booth that sits in my patio on a work
bench and exhausts the air up on to the roof of my studio.
.
Most of the over spray from my HVLP turbine blower sprayer is
collected by a detachable metal false back inside the booth and the
rest goes up the pipe through an air filter (washable) that catches
most of the rest.
The body of the booth is the bottom half of an old refrigerator,
installed upside down on the work bench. I cut off the top half,
which was the freezer, and installed it under the work bench to use
as a damp chamber.
I used a cheap home depot attic exhaust fan about 16 inches in
diameter. I mounted it in the top of the booth and ran the exhaust
air through a reducer that I paid a sheet metal shop to make so I
could use the largest home depot galvanized stove pipe - 12 inch. It
goes up and turns 90 degrees at the end to keep rain out.
.
Since the attic fan motor is right in the air stream and it
takes in cooling air from the air stream it would suck in over spray
and coat the coils with glaze.
I found that a 2 pound coffee can fitted it exactly so I ran a 3
inch air pipe from outside the booth into the coffee can so the motor
gets clean cooling air. I let the blades take care of them selves and
so far no problems.
I used to have photos of this spray booth up on the internet and I
think I can still find them, so anybody wants to see them drop me a
message and I will send them to you.
The tool you need to cut up an old refrigerator is a
reciprocating wrecking saw. I have a Milwaukee and it is a lifetime
tool. Perhaps Harbor Freigh has one for a short time use for a
cheaper price. You can get a terrific selection of different blades
for these. Cut almost anything. I found it great for cutting through
roots of a bamboo patch when installing an underground gas pipe.
