airbrushing with acrylic paint
Posted by gorilla1 on Thursday, June 21, 2018 1:21 AM

I just bought an airbrush to paint model cars.I also bought acrylic paint.The paint keeps drying in the tip while I am painting.I also bought airbrush reducer & extender base.The paint seems to be drying in the tip weather I"m using straight paint or with reducer! I'm new to this and don't know how much reducer to use.Or PSI. I have set at 20PSI.

If your paint is drying too quickly, you might be adding too much reducer or extender.  Mix your paint with thinner to the consistancy of milk.  Everyone has their favorite thinner and mine is cheap medium drying lacquer thinner from Home Depot.  Your air pressure at 20 PSI is good and you should start off with a couple of mist coats of paint and build up to a good coverage.

Don't be afraid to try lower than 20. I just sprayed one at 10 and that worked well. I find with lacquer I can't stop to look at what I painted after just one pass, ( which I always do with enamels, bad habit ) until I have finished all the spraying or the tip clogs on me.

I have tip clogging issues with lacquer, too. Actually, airbrushing lacquers is fairly new to me, so still working out its idiosyncracies. I started keeping an airbrush jar of lacquer thinner in the painting area, so if the nozzle starts to clog and spit, I run some straight thinner through it for a bit to clear it, then resume painting.

You use lacquer thinner for acrylic paints ?

I use medium drying lacquer thinner from the local Home Depot to thin all my paints, acrylic, lacquer, or enamel.  I never had an issue with it.
