Winsor & Newton Galeria Acrylic Flow Improver 250 ml
This is an additive that loosens the surface tension of water within the acrylic film. It increases flow, allowing the artist to apply areas of flat color evenly without changing the color strength. The increased flow is also ideal for masking applications (as the color lays more smoothly and evenly against the taped edge) and for flowing, gestured water color techniques. Flow improver is also the best medium for “staining” applications. Flow improver should be used only in the amount needed to achieve the desired effect.
