Use Golden's GAC Mediums to achieve complete technical control over your acrylic paints and painting environment. GAC Mediums are the raw materials from which other acrylic mediums are created. Use them to modify the working characteristics and appearance of Golden Acrylics and other acrylic paints.
Golden's other acrylic mediums are a blend of GAC mediums, the raw polymers themselves, with each other, and with other structural elements such as gels or powdered marble dust.
