Irresistables Heat Set Paints (IRHSP) were designed to cure with heat. IRHSP's can be used with other heat set paints (oil based) or even air dry paint systems and when paired together, because of the creamy nature of IRHSP paints, the pigments will blend perfectly. Use IRHSP mediums or solvents to thin. Set your oven to 265 degrees F/129C and heat for 9 minutes.  Remove your product from the oven and allow it to cool fully before handling and applying more layers. The paint will not cure unless it reaches 265F/130C. This is crucial for the success of our heat set paints. If you choose to use a heat gun, be careful not to over heat the paint. Glass or ceramic palettes are preferred to mix your colors for washes. Store your IRHSP's at room temperature. IRSHP's will never dry out.
