This medium prepares any surface for painting with watercolour. Apply it to surfaces like primed canvas, wood, glass and more. Simply brush on two coats of the medium and allow each coat to dry before painting a new layer.

The medium will deliver strong colour retention, even drying, and an absorbency similar to that of watercolour paper.
