Holbein Duo Aqua Oil Mediums were designed specifically for use with Duo Aqua Oil Colors. Use them to enhance transparency or translucency, create a gloss or matte finish, accelerate drying time, or aid brushability and flow.
Quick Drying Liquid — This liquid enhances transparency and gloss finish while dramatically accelerating drying time. When mixed with Duo Aqua Oil Colors in equal parts (do not exceed a 50/50 mix), the substrate surface will become tacky in approximately 30 minutes. Quick Drying Liquid can be thinned with water; the resulting milky appearance becomes clear when dry. While it may become cloudy over time, its performance is not affected. It is excellent for knife painting and impasto.
