Aquabord features an acid-free textured clay surface that absorbs watercolors like a fine paper. Colors retain their purity and vibrancy in a way that even the finest of watercolor papers can never match. Endlessly glaze and lift to underlying layers of color or completely lift back to white without damaging the surface. Uniquely absorbent Aquabord is perfect for watercolors and gouache, but is also ideal for casein, encaustic and acrylics. Will not tear, shrink or buckle even under heavy water application. Seal finished artwork with spray fixative for an elegant glass-free presentation.
