Citadel paints are water-based acrylic paints made specifically for the gaming and miniature model industry. These paints have been formulated according to the most popular consistency for painting miniatures. Citadel paints are thinner than traditional artist acrylics, but much creamier than the craft acrylics found in many hobby stores. This consistency may not meet every miniature painting need, however. Because they are acrylic paints, Citadel paints can be thinned or thickened with an acrylic medium. Mediums are available at any craft or art supply store.
Squeeze a small amount of Citadel paint onto your palette.
Add a small amount of texturing medium to the paint and mix well with your palette knife. Add approximately 1 part texturing medium to 4 parts paint, for a 1:4 ratio.
Test the consistency of your mixed paint by painting with a brush on a scrap paper. If it has not yet reached the desired consistency, add another part texturing medium and mix well. Test again. Repeat until the desired consistency is reached.
The same process can be followed to thin Citadel paints by mixing them with acrylic fluid medium.
