Lascaux Aquacryl Mediums are used to extend the color and still maintain their water resolubility.
Aquacryl Medium is based on the same binder used in the Aquacryl colours. It has the same matt finish as the Aquacryl colours. The Medium can be used as a first layer on a support to reduce absorbency and to facilitate subsequent colour washes to increase the binder content and consistency of strongly diluted colours and to enhance transparency. Aquacryl Medium is not suitable for a final varnish, since it remains water soluble and is not scratch resistant.
