Gamblin Cold Wax Medium can be added to any oil color or oil painting medium to make them matte. Wax Medium also makes oil paints thicker and more translucent. G-Gel increases the flexibility of wax. The Galkyds are made from alkyd resin, which is the polymerized oil of the 20th century. Galkyd speeds drying time.
Thin layers are dry overnight.
Galkyd can be thinned with odorless mineral spirits. By using alkyd resin painting mediums, painters no longer need toxic turpentine in any part of the oil painting process. To make Galkyd more matte without compromising the transparency, you can add Cold Wax Medium or you can make a matting agent by dissolving one tablespoon of Cold Wax Medium in 2 fl oz of odorless mineral spirits. Take time to break the wax into solution. The resulting solution is your matting agent.
