Tri-Art Gel Medium Matte - Matte Gel Medium is, in essence, High Viscosity paint without pigment. Formulated from 100% pure acrylic polymer emulsion, it is white when wet and will dry to a matte finish and flexible film. Our Gel mediums have a creamy, buttery consistency and are capable of holding every texture detail from high peaks to a fingerprint. Even in very thick coats they will maintain optimal flexibility. An excellent color extender or impasto glazing medium, this Matte Gel medium dries to a waterfast film wich will not yellow with time. Its superior adhesive quality also makes it the ideal medium for collage and mixed media.
