Acrylic Nightmare
Posted by ua0124 on Tuesday, November 8, 2005 10:20 PM
I am using a Badger 155 Anthem airbrush and using Model Master Acryl paint.   When I  depress the trigger I get the airflow going and when I begin to pull the trigger back no paint is coming out.  I keep pulling the trigger back and finally a huge amount of paint pours all over the model.  What a mess this has created.  Also bubbles are coming up from the paint cup.  What am I doing wrong?

Have you thoroughly cleaned your airbrush?  I've also found that my AB and compressor required me to thin the MM Acryl paint slightly and add some alcohol to the mix.

I always thin my MM slightly with alcohol and clean out my airbrush with acrylic paint remover. Before I started cleaning my airbrush extra thuroughly I had this same problem, but now it's gone. One question I have is that is this happening on the first coat? When I let my spraygun sit between coats MM acryl has a tendency to "clot up", so because of that I have taken to lightly flushing my airbrush between coats. Hope this helps. Also about the bubbles in the color cup, does it boil like a pot of water? I had that happen before.

I'll need to but some acrylic paint remover they may help.  The clogging up happens between coats and as for the bubbles in the color cup is does boil like water.  This is the fustrating part.  I have to stop and clean the AB in the middle of the paint session.

Has anyone ever thinned acrylic paint with lacquer thinner?

I've heard of Tamiya acrylics being thinned with Lacquer thinner but I have no idea how it would affect MM.  Take a little in a bottle top or something and add a few drops of lacquer thinner and mix.  See what happens.  If it works ok, dip a brush into it and see how it spreads and dries.  I'd hate to get that in my airbrush and have to clean up the mess afterwards if it didn't work.

It sounds like you might need to soak your head and spray tip in lacquer thinner to make sure there is no acylic dried in there.  Also you might try thinning your acrylics a little more and see if that helps the clogging.  The air coming back up into the paint cup is because it is taking the path of least resistance.  It can't get out the tip so it has to go the other way.

I use acrylics almost exclusively and I push down on the trigger then pull quite a ways back every once in awhile and spray into a paper towel to keep the tip free of buildup and keep it from blobbing out on my model.
