Winsor & Newton Galeria Flow Improver 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.
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 watercolor techniques. Flow Improver is also the best medium for "staining" applications.
Flow Improver should only be used in the amount needed to achieve the desired effect.
