Only Encausticbord has a ready to use surface formulated for the unique demands of encaustic painting and mixed media. Encaustic gesso is applied to Ampersand's sealed Hardbord panel to form a bright, smooth and velvety surface that is ready to use with the ancient technique of encaustic painting. The ground is not only heat resistant and highly absorbent, but also holds tight to layers of wax and collage without the fear of cracking or separation.
