For slow drying wet-in-wet techniques. Use only with Atelier Interactive. This is a water-based low-viscosity, acrylic extender designed to provide the most efficient means of reducing paint viscosity whilst maintaining maximum covering power. When added to Atelier paints it creates the best possible medium for flow applications including airbrushing and fine detailed line work. Add medium to paint with a stirring action until the desired viscosity is reached.
