General Fabric Paint Heat-Setting Instructions

Note: These are general guidelines to be used alongside the manufacturer instructions included with each fabric paint we carry.

For best results, allow painted or printed fabric to dry thoroughly for at least 30 minutes. We've found that air curing for as long as possible before heat setting—up to two weeks in a warm, dry environment—yields the best results. For faster drying, place fabric under a lamp before heat-setting. Heat setting locks color into fibers, allowing for normal laundering.

Commercial Dryer Method: We generally don't recommend home dryers, as most don't get hot enough. Use a commercial dryer preheated to a minimum of 250°F for 45 minutes.

Iron Method: Keep in mind that temperatures vary between irons. Preheat your iron to the maximum temperature safe for your fabric. Place aluminum foil on the ironing board and lay the fabric painted-side down. Press the backside for at least 15-25 seconds per square foot. Alternatively, you can use a press cloth to iron directly on the painted side, then repeat on the non-painted side without the press cloth using the highest temperature appropriate for your fabric. (Note: A longer air cure time of 5-7 days is recommended when using this method.)

Commercial Conveyor Oven: Set to 350°F for 3 minutes; use two passes if necessary. Fabric should be hot to the touch to properly set colors.

Important: Optimum time and temperature for heat-setting will vary depending on fabric type, paint coverage, equipment, and especially the specific manufacturer's instructions. Please remember these guidelines are intended as general recommendations and may need adjustment for your specific project.
