Conservation Varnish by Krylon is a non-yellowing, low molecular weight varnish that protects fine art paints against fading, dirt, moisture and discoloration. With UV light absorbers and stablizers, this varnish provides the look of dammar varnish. By recoating, your painting can have a gloss or matte finish. The results after using Conservation Varnish are colors that appear saturated and acrylic paintings that look more like oil. Krylon recommends not using this product in high humidity.
