Mixing and Storing Tamiya Acrylics

I have tamiya pain that has been mixed and stored for a while and had no problems, just give it a good stir before useing again just to be sure. As for mixing, i just mix it straight from the jar and then add thinner as desired the same as i would if useing a colour as is.

I would start with white, and then add a very small amount of black until you have the colour you want. And do it in a seperate jar, unless your happy to lose a whole jar of white.

Mix the paint & store it & you should have no problems, but leave the thinning until you actually use the paint.

Adding black to white, even in tiny quantities, is going to make things happen very quickly. It may be better to add something like XF-20 Medium Grey instead of black.

As mentioned, mix the paints but do not add thinner until you are ready to use it. Mixing the paints should have no appreciable effect on the paint's shelf-life.

Good advice, thanks.

I'm planning to sacrifice a new 10ml bottle of the flat white for this purpose, as I'll probably end up using most of it to complete the model.  I was thinking of starting by just adding like a tiny smidge of flat black to the bottle and then see what happens, and then gradually add more in tiny increments until it's where I want it.

But now that you mention it, I do have a bottle of the XF-20 Medium Grey as well.  I'll consider using that instead of the black so I'll have more control over the results.

It might be an idea just to test it first. Just put a few drops of white on a piece of plastic  and add a drop of the grey until you have what you want.

Remember to make a note of what you have done mix wise, so that you can replicate it if needed.

On more than one occasion I have mixed, only to find I either didn't have enough, wasted some paint on a duff coat, or needed some more for a touch up.
