Sennelier Thickening Impasto Medium
Size: 200 ml
It is a paste that is firm, yet light to use on the brush. For layers a few millmetres or more thick, it is essential to mix some Van Eyck Medium or oil color into the impasto medium, in order to make the paste more flexible and therefore to reduce the danger of cracks appearing. It becomes more matte by adding turpentine spirit.
