Product Description R&F’s Encaustic Gesso provides an easy-to-use, water-based ground specifically formulated for use with encaustic paints. This gesso differs from typical acrylic gessos by having a higher proportion of solid to binder, making it highly absorbent while retaining the adhesive qualities of the acrylic. With our Encaustic Gesso you can easily brush or roll on a white ground that quickly dries to a ready-to-paint surface.
