Watercolour Mediums & Grounds

Watercolour Mediums are used to change the rate of drying, increasing gloss, improve flow or provide texture. They provide water colourists with limitless opportunities to add special effects and add variations to their water colour paintings. In addition, a selection of these mediums are also suitable for use with Designers' Gouache.
