Golden Absorbent Ground is an acrylic liquid surfacing medium that can be used to create a porous, paper-like surface on many different substrates. It is uniquely formulated for absorbent action when dry. Applied over gessoed canvas, the Absorbent Ground allows for raw canvas-like staining on a protected substrate. It also allows watercolours to be used on a stable prepared canvas. Absorbent Ground, designed for stain and watercolour-type applications, is lightfast, permanent and flexible. It is not intended as a gesso alternative. It must be applied over a pre-primed surface due to its fragile, paper-like nature. Once properly sealed, it is a permanent acrylic film that does not need to be kept under glass. Golden Varnishes (Polymer & MSA) will protect the artwork from environmental factors such as sunlight and dust.
