Impasto Medium is a water mixable impasto and texturing medium for use with Artisan oil colours. It will maintain the tube consistency of the colour and speeds the drying of the colours by about 50%. For thick impasto, build the texture in several layers allowing each layer to dry first, mixing the impasto thoroughly into the colour before use.
An excellent medium which allows superb consistency control for palette knife work Simon Robinson (Barnet, United Kingdom) on 15 Mar 2013
