Acrylic Washes and Glazes: What, When and How?

About this lesson

Explains the practical difference between thinning acrylic with water (a wash that sinks into absorbent surfaces) and extending it with medium (a glaze that sits on top), using very dilute paint-to-medium ratios. Photo tests compare surfaces, gloss versus matte mediums, optical color mixing through layers, and application with brushes, knives and squeegees.
