Rheotech Gel Mediums provide artists with a clear-drying, heavy body acrylic gel that is ideal for extending colour, creating glazes and texture. The viscosity of Rheotech Gels is consistent with that of Rheotech Acrylic paint. They can be thinned with small amounts of water for glazing or used as a clear, waterfast seal for sculpture. Their superior adhesive quality also makes them the ideal medium for collage and craft applications such as decoupage. Rheotech Gel mediums are available in gloss and matte finishes.
