Tri-Art is committed to operating an ecologically responsible factory. For example, through a process of flocculation, separation, pressing, filtration, and re-dispersion, Tri-Art returns the water used in its manufacturing processes back to the environment in a cleaner state than when it arrived.
Also, by using 100% of the waste pigments recaptured during production, Tri-Art has created Sludge, a high-quality gesso with more pigment solids than any gesso in its price range.
Sludge is an economical alternative to both a neutral ground and neutral color. It can be used in place of gesso when a muted base is desired. Sludge is semi-opaque and, although gray in tone (colors will vary), can be used in small quantities as an opacifier or medium-toned color extender. Because of the quantity of solid particulate in the paint, Sludge has a light tooth that also makes it a suitable ground for mixed media applications.
Because Sludge is made with 100% acrylic emulsion, it is comparable in character to other acrylics. Therefore, it is highly adhesive to a variety of surfaces, dries to a water-resistant semi-gloss finish, and can be easily applied with a variety of painting tools.
