Matt clear coat = gloss finish!?

[RobL]

Hey all

 

I'm having a problem with my clear coats.  I've got two tabletop gaming figures that I've tried applying a matt clear coat to using a brush.  The figures are painted with Vallejo Game Color.  I've tried two types of matt clear coat.  Windsor and Newton Galeria Matt and Tamiya XF Flat Clear. 

 

I had used the same brush for a gloss clear coat (Windsor and Newton Galeria gloss), and also a satin clear coat (or at least a 50/50 mix of Windsor and Newton Galeria matt/gloss) prior to using it for the matt coat.

 

I have washed the brush out.  Several times.  Between types of clear coat.  I did not, to my knowledge, contaminate my matt clear coats.

 

However now, every time I've put down a matt clear coat on these two figures with this brush the finish ends up being shiny!

 

I did get it to end up a little flatter overall, although still shiny in patches, the other day on one of the figures using Tamiya XF Flat Clear, but on the other figure it still all ended up shiny - same pot of Tamiya XF Flat Clear, same brush, applied minutes after.

 

I'm not doing anything different on each figure in terms of applying the clear coat by brush.

 

I don't have a spare brush I can use to rule out the brush as the fault. 

 

I've used the same clear coats on other figures and also aircraft models, both by brush and airbrush before, loads of times, with no problems of matt clear coat coming out shiny.

 

Please can anyone tell me what might be going on here so that I can try to sort it out?

 

Thanks in advance.

I had that problem with Humbrol. Hopefully someone can answer this.

OK, so, I fixed this!

 

Well, with my Windsor and Newton Galeria matt clear coat at least.  Don't know about the pot of Tamiya XF Flat clear.

 

It seems the W&N G matt clear had separated, or whatever the stuff does.  I shook it up, applied more to the two figures, for the nth time, and hey presto, a flat finish was achieved.

 

There's very little in my Tamiya XF Flat clear pot though, so I doubt shaking that up would make any difference.
