Cold Wax Medium is a naturally white, beeswax-based medium formulated to a knife-ready consistency. It thickens oil colours and gives them a rich, matte finish, perfect for artists seeking texture and a subdued surface sheen. Blend it into your paints or use it to adjust the gloss level of Gamblin mediums and varnishes. Cold Wax Medium can even be applied on its own as a matte varnish for a velvety, non-reflective finish.
