OPEN Thinner is a water-based additive designed to thin the consistency of OPEN Acrylics without altering open time, as well as maintain and adjust the workability of colors on the palette. It can also function as a thin-bodied retarder when used with heavy body or fluid acrylics. OPEN Thinner contains no binders and will not form a film when used.
Available in 1 oz. and 4 oz. squeeze bottles
