The Setacolor Expandable Paint is used to mix in with colors to create 3D designs. It is an auxiliary from the Setacolor line of water-based fabric paints, which features Opaque, intense, concentrated and highly covering contemporary colors for all light and dark colored fabrics, as well as transparent, Light Fabrics colors for light colored fabrics. They are ready-to-use, lightfast and are mixable with each other. Both Light Fabrics and Opaque paints can be used on any pre-washed fabrics: natural or synthetic (with at least 50% natural fibers); light weight or heavy weight. After air-drying for 1 hour, iron the reverse side of fabric for 5 minutes (cotton setting) OR place in preheated oven for 5 minutes at 300°F (150°C). Once colors are fixed, fabrics can be hand-washed or machine-washed at up to 100°F (40°C). The Expandable Paint is available in a 45 ml bottle.
