Problems with Varnish / Decals - sorry if this has been done before.

Hi everyone,

First of all apologies if this is a common question, I certainly know from searching the interweb that it's a common problem but I haven't managed to find if there's a solution to my problem.

Basically I try to stay away from decals wherever possible as I hate the sheen from the carrier film, but I hadn't really been applying them properly and so thought for once I would go the whole hog and use varnishes and decal softeners etc.

However model shops are few and far between in my area and I only like to use water based products where possible so my options for products were limited.

I needed to apply decals to a GW Valkyrie kit, but have run into problems after varnishing it.

I applied a layer of gloss varnish to the area receiving the decal. I used GW 'ArdCoat for this which I applied with a brush. This seemed to work fine.

I then used Humbrol Decal Fixer, which I first applied to the area where the decal would be, and then applied it to the decal once it had been set in place.

I left this to dry overnight and then applied another layer of 'Ardcoat, again using a brush rather than a spray.

All of this seemed to work fine, the problem came the next day when applying the paint on matt varnish.

The only paint on water based matt varnish I could find was Revell Aqua Colour Matt Clear (number 2 I think).

I mixed some water with it as instructed on the pot, in this case about 2 parts varnish to 1 part water, which I made sure was clean.

I painted it on and waited overnight for it to dry.

Unfortunately it has washed out my edge highlights, as well as blanching the colour of the panel a little too. However the most frustrating thing was that it left areas of fogging on the panel, and brush and tide marks too.

After consulting a friend who uses varnishes more often than me he said to apply a further thin coat, which I did and this has greatly reduced the fogging and brush marks, but not entirely. My biggest concern now though is that the panel in question is tonally different to the rest of the Valkyrie, the wing in this case, and my highlights seem to have almost dissappeared.

Is there any way to correct this now, or is it too late? I was very careful to make sure I applied thin even coats, but maybe I shouldn't have added water? Or is it just that I should have used better products?

It's a shame though as the decal looks good, no sheen or hint of carrier film, it's just the area it sits on now looks crap! :(

Unfortunately I don't have photos to show you at the moment as my camera is buggered, but could probably get some over the weekend.

Please could anyone advise me where I went wrong?

Cheers. :)

Welcome to the wonderful world of protectants and clear coats.

For decals use solvaset if you can find it.

The interclear (coat of varnish you put on before the decal) would be better applied as an aerosol. Testors Dulcoat is the can of choice, but Krylon Krystal Kleer would work too. Very light coat.

Once the decal is set, let the whole thing cure for a day or two. Repaint over the edges of the decal if possible to help hide the fact that it is a decal....

Final varnish again, one light coat of Krylon, let cure, one heavier coat of krylon, then a light coat of DulCoat to matt it down.

The matting agents in varnish will knock out highlights. The varnish itself has a slight yellow tint (even if you don't notice it.), lacquer has less yellow in it.

Fog is usually a result of humidity. Try letting it set somewhere warm, not hot, but warm to see if the moisture can be driven out. A second light coat sometimes opens the pores of the previous coat and lets the moisture out. Barring that, it is a dip in the paint stripper.


I'm not a fan of brush on or of water based varnishes.

Firstly remember that decals use water. You need to give them at least 24 hours to fully dry. After applying the decal gently use Q-tips to work the water out from under the decal. Also, do the decals before the highlights. The spraycans contain chemicals. Do the decals then spray whatever (dullcoat, matte or gloss)then do your highlights.

Cheers guys,

I hadn't thought about leaving the decals overnight, that must have been what happened. That's frustrating because I was so careful to leave the varnish coats and decal softeners overnight, but guess I got a little impatient with the decals.

I hadn't wanted to use a spray varnish as I was hoping to only apply varnish to the odd areas where the decals were going. I had thought carefully applied thin varnish would have been ok, but I suppose it's all a learning curve. :)

And in future I think I will highlight after the decals. I only used decals on vehicles, preferring to freehand where possible on minis, so the large areas won't be aush a problem.

I must admit I have been away from the computer as I have been to Salute and then at home painting, but I managed to pick up some Vallejo matt varnish over the weekend and this has been going on a treat.

I am still plucking up the courage to start using an airbrush, which I suppose would negate a lot of these problems?
