Derivan Impasto Medium Brand_Generals The formulations are non waterproofThis 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 which is 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.
