This multi-purpose acrylic primer and extender helps prevent Support Induced Discoloration (SID) caused by impurities that are drawn up as acrylic paint dries. GAC-100 is also useful for diluting and extending colors, increasing brushability, flexibility and film integrity. As a primer it works well sizing fabric and sealing wood. GAC-100 will wet out solids, including pigments, more readily than other polymers. Also useful for artists formulating their own paints.
