Tri-Art Gesso Sludge
SLUDGE is the latest effort of Tri-Art to create environmentally-conscious and superior art products. Sludge is a by-product of acrylic paint manufacturing. It is the combination of the precipitated solids amassed from wash water, which has then been re-processed into thick and thin acrylic paint formats.
SLUDGE is an economical alternative to both a neutral ground and neutral color. It can be used in the place of gesso when a muted base is desired. SLUDGE is semi-opaque and although grey in tone, can be used in small quantities as an opacifier or medium toned color extender.
