Model Master Flat acrylic military colors coming out semi-gloss

Did you stir the paint instead of shaking? My guess the sediments have settled at the bottom and you need to give it a good stirring.

You may be putting it on too thick.  Flat paint will take on a semi-matt sheen if applied too wet/thick.  Same thing when using airbrush.  You can get semi by putting on gloss enamel real thin/dry, or matt enamel too wet.

For brushing, since a very thin coat may not cover completely, put on a couple of coats, each applied very dry.

That's possible. I try to do both, shake them really well then stir the bottom. But I know I forget sometimes.

Thanks for the input.

I disagree with Don as well. It sounds more the case of not stirring the paint.

You're doing it backwards. Stir the paint FIRST then shake the bottle. You want to loosen the sediments before you shake the bottle.

If it still gives out the slight sheen, it's possible you may have got an old bottle or a bad batch.

Either that, some are actually semi-gloss, not flat.
