Global Colours Pouring Medium is a high gloss, self-levelling medium. It will create a smoother flowing consistency while also keeping the thickness and opaqueness of the acrylic paint. It is flexible, non-yellowing, and water resistant, and retains a high gloss and wet appearance when dry. Milky white when wet, this medium will dry transparent. This product can also be used as a varnish. Allow to dry for 48 hours.
