Enkaustikos Wax Medium is made from a 1:1 ratio of U.S. Pharmaceutical Grade Beeswax and Damar Resin. Our XD Wax Medium features extra damar. This Wax Medium has a higher content of damar resin than the original, 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 our original Wax Medium. Once cooled however, it is resistant to surface alterations from scraping or incising and offers a hard film. Like the original Wax Medium, XD can be used as a wax paint extender for glazing, and especially useful as a topcoat. If you want to achieve a glass like surface with a single topcoat, this is the product for you. XD comes in our resealable silver bags for easy storage.
