Tamiya Flat Paint looks gloss

Are you sure it's XF-1? Tamiya Gloss is X-1. Just a thought...

I get this from time to time, mainly with black but on the odd occasion with other colours. It just needs a proper mixing. Try getting one of those battery operated paint stirrers.

Thick coats of flat paint, and thin coats of gloss, often take on a semi-matt appearance.  You can control the gloss of paint somewhat by varying the thickness of application. Flats must be put on fairly thin, whether airbrushing or brush painting.

With flats, multiple thin coats will work much better than one really heavy, wet coat.

Don is correct on the applications.  I just hand painted the props flat black (MM enamel) on my latest build a 1/48th V22 Osprey and the edges are glossy because I applied it too thick. 

The best dead flat black to brush by hand is Humbrol, but has to be mixed every couple of minutes if brush applying.

If you airbrush Tamiya XF-1 it will go on dead flat.  Brushing anything by hand in any color has a whole set of problems that can occur on that learning curve.

Always mix well with patience. You don't need to buy a mechanical tool to do it. I use a slim paintbrush handle.

Yes I double checked the Paint. It is supposed to be the Tamiya flat paint. Thanks. 

I was thinking about not being stirred as well. That would be the easy answer, I will try again tonight or tomorrow. I will let you know. Thank you for taking the time to reply.

I did not know that about the thin coats for flat. I am sure I may have read that but did not know the importance of it as it pertains to gloss. I will post a pic tonight of tomorrow. 

Then we will test out the mixing theory as well as vary the thickness of the paint. 

My other flat paints went on pretty well with the brush so I am sort of locked in on the issue has to be something with this paint. Maybe it is technique or that I need to mix it more thoroughly.

Thank you for your input on this rather trivial issue.

Thank you for your input. I will let you all know what I find after some more experimenting.
