How it works
How heat set paint works
Heat set paint does not air-dry. It stays workable on the palette and on the piece until you heat it to 265°F or above, and then it is permanent.
Paint
Apply it straight from the jar. It handles like oil paint in body, opacity and translucence. On a non-porous surface it will not dry in the open, so you can keep blending and come back to it later.
Heat
Cure at 265°F or above for 8 minutes or longer. A heat gun for canvas and crafts, an oven for small pieces, even an iron. Heat sources vary, so test on a spare piece and adjust.
Finish
Matte or Satin Varnish straight from the jar in a thin, full layer, then heat again: 265–270°F for 12–15 minutes works best. Thick Medium and Glazing Gel build texture and custom color.
FAQ
Common questions
What does “heat set” mean?
The paint does not air-dry. It stays wet until it is heated to 265°F or above for 8 minutes or longer, and then it is permanent. That gives you unlimited blending time.
What do I heat it with?
A heat gun for canvas painting and other crafts; an oven for small pieces; an iron works too. Heat sources vary and so does the time they need, so run a test piece before the real one.
Is it safe to have in the studio?
Gemini® colors and varnishes are made with non-toxic ingredients and no additives. Gemini® Heat Set Thinner is non-solvent, non-flammable and non-toxic, and cleans off brushes and surfaces with rubbing alcohol or soap and water. If you prefer a solvent, Gemini® Heat Set Solvent is an odorless, colorless, low-toxicity mineral spirit made for the line.
Will the color fade?
The pigments are inherently UV-resistant and weather fast, with high tint strength. A little goes a long way and the color holds.
How do shipping and returns work?
Orders ship in 1–2 business days, and US orders over $100 ship free. If something isn’t right, contact us within 30 days for a refund.
