Acyrlic paint issues

Thanks Patraw and ẈĀŦƧĦĪƧ₣Ā₵Ė

Over the years, I've noticed that some colors just seem to be thinner than others, for whatever reason (I've got a bottle of Forest Green that's almost like water, it's so thin, and it came that way when I bought it). Shaking sometimes helps, as ẈĀŦƧĦĪƧ₣Ā₵Ė mentioned, but not always. As long as you're getting good coverage with it, you should be okay. Personally, I'd rather my paint was too thin than too thick.

I've also found that, if I use a particular bottle of paint for washes a lot over a long period of time, water can gradually accumulate inside the bottle from dipping the brush, which can also thin the paint out some. If you leave the bottle open for a while (say, a few hours, but not days), that'll give a chance for some of the water to evaporate which should restore some viscosity.

I figured it was something like that, yet after shaking it for a good 3 minutes, the paint still has a watery consistency. It goes on fine though, really it's just a minor concern.

Usually when I have that problem it's because the pigment in my paint has separated and sank to the bottom of the container so stirring it well with a popsical stick and also shaking usually fixes it. I've also seen some products that are sold as paint thickeners but I've never tried one myself and can't vouch for it.
