We have tried: We ironed the reinforcement dry (without steam) by pressing for about 10-15 seconds at about 150 °C. We applied the iron in sections, we did not move it back and forth. After ironing, it is important to let the ironed part cool down thoroughly. If the reinforcement does not hold well, it is a good idea to extend the time the iron is pressed, but do not increase the temperature. We always recommend testing on a sample.
