Sennelier Watercolour Medium Gum Arabic

From £17.99

Basis of Watercolour that can be used to increase gloss and luminosity.

A pale coloured solution that increases the gloss and transparency of Watercolour. It also slightly extends working times. It is the binder that is used in Watercolour Paints because of its ability to dissolve easily in water and form a strong layer that bonds the pigment to the paper and increase luminosity as the water evaporates away.
