Acrylic Medium and Varnish is a versatile additive based on acrylic epoxy. It comes in the form of a milky-coloured liquid and turns clear when thoroughly dried. It doesn't darken nor turn yellow over time.
When added to the paint, it thins it out, controls its opacity and adds shine. Used as a varnish, it creates a glossy, transparent layer over the artwork and protects it from external conditions.
