Amperand's Museum Series Aquabord™ is an acid-free textured clay surface that absorbs watercolours like a fine watercolour paper. Retaining colour purity & vibrancy against a very hard white background surface. When compared with watercolour paper, this multimedia panel simulates the absorbency and texture of cold pressed paper surface, but allows colour to be lifted back to white easily while also leaving the richest, most vibrant colour possible. This workable surface provides natural looking highlights, fluid glazes, transparent subtle layers, and the ability to lift colour while the surface is wet or even after it is dry. Uniquely absorbent Aquabord is perfect for watercolours and gouache, but is also ideal for gouache and acrylics. Will not tear, shrink or buckle even under heavy water application. Archival, and made in the USA.
