AK-Interactive Real Colors turning to sludge in my airbrush
Posted by cervelo_mark on Sunday, September 12, 2021 9:22 PM

I am using AK-Interactive Real Colors brand paints in my Paasche Talon air brush for the first time.  They spray well straight from the bottle without thinning.  When I am finished and want to clean out the airbrush I pour in home-made airbrush cleaner to flush it out.  A chemical reaction occurs and the paint turns to sludge and makes cleanup very difficult.

It is hard to describe what happens to the paint.  It thickens up and clumps together in long strings and bonds to the insides of the airbrush very well.  The nozzle becomes totally clogged and takes a lot of time to clean out the old paint.

Has anybody else out there seen this or a similar problem?

Thanks

It's your home made cleaner causing the problem. You need to experiment with other cleaners in a safe container, glass or metal, to see how they react with the paint before trying them in your airbrush. That's how I try out new combos before putting them into my airbrush. I've read of too many similar horror stories on here over the years

Yup, its your home brew thats causing the issue. AK and Vallejo are super sensitive to certain thinners that work well with other paints. That being said, clean with water or even Windex and you will have no issues. I use water mostly and Windex for more stuburn jobs and have for years with no hassles and it won't hurt your AB.

The manufacturer has recommended cleaners and thinners for their products.  Granted, each market's their own, but Is the money saved worth the time invested in trying to clear up a big problem?

Only the individual can make that decision.

I use AK all the time. For cleaning I run lacquer thinner through my brush. Comes out perfect

I though AK Real Color was lacquer, so I'd think lacquer thinner would work as mentioned in the message above mine.

That was your first mistake - attempting to use "home made brewed" thinner; which  everyone has already mentioned. FWIW... I always follow this simple rule of thumb when using new paints... ALWAYS use the manufacturer's brand of thinner recommendation first before you try an alternative thinner. Ask me how I know. 

Each paint brand will have a chemical reaction to certain types of thinner one way or another - both good and bad. Hope this helps.

...home-made airbrush cleaner...

What is in your home-made airbrush cleaner?

Others have mentioned using a manufacturer's proprietary products with its paints.  But others have mentioned using lacquer thinner, which ought to have worked relatively problem-free, too.

So, what's in your cleaner?

I use Tamiya X-20A thinner for airbrushing AK Real Colors without any problem.

I clean the AB with 91% alchohol from the drug store.

No problems.
