Vallejo model paint thickening the bottle
Posted by Shipwreck on Thursday, March 30, 2023 1:17 PM

Some of my older, 5-10 years old, Vallejo model paints are thickening to a sludge in the bottom of the bottle. My red would no longer drop from the bottle. I added about 20 drops of paint thinner with no effect. In desperation I dumped about 30 oz of distilled water in it and it seems to be flowing fine; but what did I do to the paint? any suggestions are appreciated. Thank you

I can't speak for Vallejo specifically since none of mine have dried up. But my track record with dried or thickened acrylics isn't good. An exception is Stynylrez primer, that usually takes mixing with a Badger power mixer. But it's not that it's dried just settled and will never mix back in by hand with a mixing stick.The power mixer does the trick in that case. Any truly dried acrylic I've encountered is usually junk if trying to thin them back out. Thus far anyway.

All you can do is try them out and see what you get.

I've been using Vallejo Model Air paints for years. I have had a few settle out and a few just plain thicken. In both cases, I added distilled water and mixed with my Badger battery powered mixer. All of them came back and are completely usable.

Stay Safe.
