This thickening gel is designed for water-soluble acrylic paint and mediums. It produces a matte surface sheen when dry. Used in small amounts, it produces handling characteristics very close to that of oil or encaustic paint. At higher concentrations it can thicken paint or mediums to sculptural consistency. Drying time will be between 24 hours to 7 days depending upon amount of thickening gel added to paint or medium. Available in an 8oz Jar.
