4 oz. Flow Aid Additive Liquitex

Increases the flow of acrylic colors on all surfaces. This handy additive will give more even lay-down in flat brushing techniques (i.e., hard edge painting), and it allows better, deeper staining techniques (i.e., color field painting.) Also produces a fluid spray when mixed with acrylics in airbrushes or air guns.
