Pre-paint question
Posted by bj342 on Tuesday, June 5, 2007 9:21 PM

What type tack cloth is best to use?  I'm having a problem with minute particles, almost like tiny, tiny hairs, showing themselves during airbrush painting sessions.  Beginning to think my lint-free clothes are not lint free.   I do not have a paint booth.  Steps currently taking:  1.  wash model-allow to air dry  2. apply liberal amounts of "Plastic Prep" - allow to air dry  3.  blow off model with reasonable pressure setting on air compressor 4.  start airbrush session and particles appear here and there.  Not lots...but enough.  Paint sprays even with good coverage, no spits or sputters, and do have a water trap.   Any thoughts or comments concerning what type tack clothes you guys are using or what someone may gleam I'm doing wrong.  Thanks.

Just a thought/question. When you blow off the model do you also blow off your painting area/surface? And if so how long do you wait afterwards befor painting?

Just thinking that maybe if your not waiting long enough for the airborne particles to settle. I blew off my area once and then hooked up the AB.Sign - Oops [#oops] Of course I ended up having to strip that model to get rid of particles and small lint fibers.

Take a can of air, the same kind used to blow out dust from computers. Use it to dust down your painting area and wait 20 mins for dust to settle. Before starting airbrushing take a large cosmetic blush brush ( Yes, the kind your mom, wife, or girlfrend uses to powder her cheeks) and brush off any particles that settled on model surface. Do this evertime between spray coats after paint has dried to the touch. This helps keep paint lint and dust free. Light sanding with a 4 grit nail polishing stick will also remove lint and dust after painting.

Thanks, guys, for the input.  I had failed to mention that I'm running a de-humidifer 24/7 in my painting area.  Prior to a paint session I start up the A/C an hour or so before.  A friend advised that using the Plastic Prep, in combination with the de-humidifer, which lowers the humidity, is creating static potential.  When air leaves my AB, through the metallic nozzle, same is being postively charged, i.e., my model becomes a dust magnet.  I'll roll all your advise together and see what happens next paint session.  Thanks.
