Hello Dakka,

I painted my Space Hulk door bases with a BM drybrush, then Badab Black wash and I was pretty happy with the result. Instead of using Dullcote I used a heavier flat clearcoat paint from Lowe's that I've used before without complaint (I can't remember the name, starts with a V... I'm at work).

Anyway, when it dried, my colors were different! The BM had been turned into more of a grey. I'm not sure what to do now - I could just repeat the BM drybrush/BB wash and then dullcote it, but I'm afraid that the 2 different brands of paint might interact poorly. You guys think I need to strip them?

Also, I've used this exact can before and never had this happen. Anyone know why?

Did you varnish it in a wet or cold climate?

If yes , simple redo it on a warm sunny day.

No worries !

Yeah, actually, I did it in my basement. I just moved my stuff down there after my sister moved in and took my painting room as her bedroom ( ) and this is the first thing I sprayed that wasn't a black basecoat. So it was both cold and damp.

Now I'm really glad I asked because I didn't realize that temperature made a difference.

I know you said you've used it before but sometimes spray-on varnish from DIY stores aren't a good option. This is because the paints you use are usually water based while the varnish is solvent and that sometimes causes a reaction.

What infilTRAITOR said.

Solvent based varnishes can dissolve the resin in acrylic which would cause mixing of the black wash and silver. This becomes grey.

Avoid it by varnishing with an acrylic varnish.

I recently Dullcoted some Bretonnian Men-at-Arms and their Boltgun-painted shield rims, helmets and spears definitely lightened into an almost fortress-grey color much like your Space Hulk doors.

Humidity = 52%
Temp = 70 degrees Fahrenheit

Just thought I'd put that out there.
