This wax medium has a higher content of Damar Resin than Enkaustikos Wax Medium, giving it a thicker consistency when liquified. It also has a sticky tack while drying for easy texture build-up and will stay pliable for a longer time than Wax Medium. Once cooled, however, XD Wax Medium is resistant to surface alterations from scraping or incising and offers a harder, glossier film. Like Wax Medium, XD Wax Medium can be used as a base coat, wax paint extender for glazing, and it's especially useful as a topcoat. If you want to achieve a glass-like surface with a single topcoat, this is the product to use. A rigid support is recommended when using XD Wax Medium.Note: Enkaustikos Wax Mediums contain Damar Resin, not Damar Varnish. Most artists are familiar with Damar Varnish, which is made by dissolving damar crystals in turpentine. Many encaustic recipes call for Damar Varnish containing turpentine which is not studio-safe. Because there is no need for solvents in an encaustic studio, Enkaustikos filters Damar Resin crystals with heat instead of using solvents of any kind, making the Damar Resin both a people-friendly and earth-friendly product.
