Museum Series Gessobord is a trusted, professional-quality, prepared wood panel for artists. The cradled frame is made with premium grade, 13-ply birch plywood for maximum stability and a clean, finished look. The superior quality acrylic gesso ground does not dull colors and the wonderful lightly sanded surface provides exceptional brush control with both oils and acrylics. Made with 1/8" hardboard and Archiva-Seal technology, the surface is acid-free, non-yellowing and archival. Gessobord is perfect for traditional and water-based oils, alkyds, acrylics, collage and mixed media.
