PPG Concept curing question

[Bob Kane]

I was spooked by the Concepts paints at first but with
reasonable care you can spray safely. I built a small
spray booth, roughly 4' wide, 8' long, and 6 1/2'
tall. It is made of furring strips covered on all
sides with clear drop plastic. There is a 20" box fan
mounted on one end in the center pulling air out of
the booth. The booth sits in my garage with the fan
blowing out towards my driveway. I originally thought
I would be in the both with the plane, but it turns
out it is easier to stand outside, so one side of the
booth is covered with plastic up about half-way. I
wear a 3M mask #07193, with a two stage filter of
activated charcoal and a fine filter. If you can smell
fumes you have an inadequate mask.

I spray with the garage door open (and the cars moved
out of the drivway) so the fumes are blown outside. So
far, I have not detected any paint on the filters of
my mask, so the booth is doing a good job of pulling
the overspray out.

I use a Chinese HVLP touch-up gun. I plan on covering
this in my next K-Factor article, but setting the air
and paint flow needles is critical, analogous to
setting needles on an engine. Make sure you test spray
on something to check your seetings so you get the
right amount of air and paint.
