Gloss and Semi-Gloss Gel Mediums — Tri-Art Gloss and Semi-Gloss Gel Mediums are, in essence, high viscosity paints without pigment. Formulated from 100% pure acrylic polymer emulsion, they are white when wet and dry to a glossy or semi-glossy, flexible film. Tri-Art's 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, Tri-Art Gel Mediums maintain optimal flexibility. They dry to a waterfast film which will not yellow with time. This makes them excellent as a color extender or impasto glazing medium. Their superior adhesive quality also makes them the ideal mediums for collage and mixed media.
