hello everyone i had posted this in with another title so scrap that one.

iam having some issues with the vallejo matt varnish.when i shot it it came out frosty.
so far i have put two layers of sin filter brown for dark green thinking that might fix it but still look to me a bit frosty.my questions are
1.is this something i did like too thick?
2.what will fix this?
thanks for the help still trying figure the dos and donts of all this

First off did you shake the bottle,also did you thin it down with thinner or water.I used the same stuff the other day and thinned it with water and it was ok on my panzer IV.

Id just spray light coats of the base color over the white bits and add weathering should cover it.

I have been fighting this problem with my matt finishes. I live in a very dry climate and use an airbrush. I have painted entire model and had it look like it was covered in dust.

The info I have read on this forum before said it was do to the mixture drying on the way to the surface. This last time I mixed Tamiya Flat Base with future and tried again. I kept the air pressure down to minimum and tried not to let the brush get to far away. In 80% of the places I sprayed the finish was good but I had areas especially on the road wheels (track) where I reduced the amount of paint coming out of the gun while spraying so I could get in the tight areas and not make it run. When I got done I had white frost an my wheels. So I hypothesis at this point that when I reduced the amount of paint but not the pressure the matt dried again on the way to the surface. My next time I am going to thin the mixture more and reduce the air preasure and just go lightly and slower and hope that will do it.

Sorry that I am not being real definitive here but it sounds like we are running into the same thing so I share my trials.

I also read where you can often fix it by spraying future on the area again, let it dry and then try the matt again. I tried a small spot and ended up with shinny white dust

thanks reply about this the issues that i was having were all by my own doing
1.i had a heavy hand and took thick
2.my pressure was too high cause the matt to dry before getting to the target
3.and the most important one of all that it was raining outside.
i let it sit in the sun for a few and it was not so bad.
plus i did not thin the vallejo matt with water or thinner.
and the next one up to paint iam going to shoot plastic card in all the steps just to make sure have have been using cardboard so i would get false results

Hi

I understand from the many posts I have read that this is quite a common problem and is often blamed on the way Matt Varnishes are made. I understand that most varnish makers use pumis as their matt agent and this can give a dusty or milky apperance when finished.

I have tried most of the different Matt Cotes available and have seen this problem to some extent in nearly all of them, with some being quite bad, Humbrol Matt Cote springs to mind as being one of the worsed offenders. One thing most people comment on is that these Matt Varnishes need an a lot of mixing, with most people ending up have to resort to some sort of electic mixer before any form of satisfaction is attained with these products.

I have found that one of the best is Xtracolors Matt Clear, but only use the Enamel version, I cannot vouch for their acrylic version.

Have't used any of those matt coats advised.

Always used a Testors dullcote for 18 years ,
used on a 50/50 thinning base .
I'm heavy handed with the matt coat as well and like to pour it on all over the model.
Have found once set overnight ,24 hrs or so it handles the washes and weathering quite well.

No shine ,no fuss
