Dammar is a resin-based varnish that, when mixed with oil paint mediums, thins the paint, increases its transparency, and speeds drying time. Used alone as a top coat, it seals paintings and adds a glossy finish. Be sure, though, that your painting is thoroughly dry before applying it as a final varnish.
Apply a layer to shield works from dust, dirt, smoke, scuffing, and moisture. This varnish deepens pigment colors and lends a high-gloss finish to final compositions. Note: Wait at least six months after painting has thoroughly dried before applying this as a final varnish.
