Matt Medium extends the colors, increases their fluidity and transparence, and softens the blending of brushstrokes.
It heightens the flexibility of the colors, and their adhesion to the surface.
Does not yellow or change tonality of the color.
Can also be used as a binder for dry pigment.
Matt Medium can also be used in small amounts to thicken Vallejo Model Wash. It will also extend the working time of the wash.
