Used as a ??nal varnish over a dried, well-cured acrylic painting when a ??at, matt or very low sheen is required. Most suitable as a protective coating particularly over large works exposed to damage in public galleries, commercial paintings required for ??oodlit photographic reproduction and paintings that would be improved by eliminating unbalanced glossy highlights. It is water-based and may appear slightly milky whilst wet. The effect disappears when the ??lm is dry.
