This medium is a heavy-bodied paint, free of colour pigmentation (it isn't a gel). It is most valuable for oil painting brush stroke and impasto techniques, particularly when heavy built-up areas of colour are required.Impasto Medium dries to a low subdued sheen similar to the sheen on a dried paint film of acrylic colour. It is equally water-resistant. Impasto Medium allows for free intermixing with the Derivan colours in any proportion. There is little visual colour loss when equal volumes of a Derivan colour and Impasto Medium are intermixed. Although Impasto Medium is not fully transparent when dry, it does not appear to alter the richness of Derivan colours in any way. Impasto Medium is also suitable for use as a light modelling compound.
