So this is a weird one. I just spray varnished some AWI regiments outside, and they already had the colors attached to the command models, which is how I usually do it. I've used Dullcote spray on paper flags before and it has no ill effects on them whatsoever, it simply coats them. However, today I was trying out Ak Interactive spray varnish. And to my dismay it heavily frosted the flags. The models were varnished normally and the finish on those is totally fine. Luckily, on a hunch I had a feeling that a brush on varnish would eradicate the frosting, and indeed it did! Irony is, I used AK's brush on matte varnish which is an absolutely fabulous product. Seems that you can do the same cure for paper flags as you can for when people have encountered frosting on models which they cured by doing a brush on Dullcote over the spray frosting. But this all leads me to a larger question. Is paper not a surface that a spray varnish can be applied to? As I said, I've done it with Dullcote spray and the flags were totally unaffected. |

I give flags a coat of diluted white glue to harden them and give them shape before varnishing. After the dried glue, there is no frosting with spray varnish so far, but I guess frosting is a thing of weather conditions and distance from the spray to the miniature more than anything else. |

I always brush on some gloss varnish to seal the flag before spraying with Matt varnish once dry. |

The paper flags I have done were always hardened with thinned white glue, and I assume that sealed them. Whether my spray varnish was acrylic (Future or Liquitex or another brand) or lacquer (Dullcote), frosting didn't occur. Varnish frosting can have several causes but as I understand it, the top layer cures first, and the minute white frosting is trapped underneath. If it's trapped impurities (from spraying through dust) or badly cured blobs of varnish (from spraying in hot weather), then not much can be done. If it's cavities from air bubbles or minute sections of uncured varnish, then softening the top layer with solvent will fill the voids and allow the deeper layer to continue curing. An additional layer of varnish of course will include solvent. |
