Mixed with Cuní colours, it increases their open time and the final drying time. It provides more fluid and transparent colours. Useful for blending and shading, for giving continuity to monochrome areas and for wet-in-wet techniques.
It does not alter the durability of the paint film. Colours remain wet on the palette for prolonged periods.
