One little bottle that quietly upgrades every acrylic on your desk. Green Stuff World's Master Medium mixes into acrylic paint to make it behave more like oils — better flow, smoother levelling, more transparency and a longer working time. Blend it with pigments and you can even mix your own custom paints from scratch.
