Golden OPEN Thinner 29ml & 118ml

Golden Open Thinner is a specialised additive designed to thin Golden OPEN Acrylics without accelerating their drying time. Unlike water, which can break down acrylic binders, Open Thinner maintains paint strength and film integrity while improving flow, transparency, and brushability. It is ideal for artists who want extended working time, smoother blending, and more controlled washes with OPEN Acrylics.

This additive contains no binders and should be used sparingly or mixed with OPEN Mediums for best results. Perfect for glazing, fine detail work, and techniques that require long open time.
