I’m currently making a massive shield and I’ve decided to do a stone work pattern on the decorative edge, I have a really awesome looking pewter mica powder that I’d love to coat the stonework in. I’m trying to figure out the best possible method but I’m open to suggestions.
Yep! You can mix the mica powders in to your paint or sealant. The former will add a bit of a tint or shimmer, while the latter will have more of a transparent effect. Make sure to blend it very well - if you mix it too thick you’ll get ugly lumps and streaks.
Honestly, I find acrylics to be far more reliable for these effects. Mica powders are cool, and they can totally make your project - but they can also wreck it just as easily.
