Glue is oozing out around the crystals.  7, 8, 9, 10

CAUSE RECOMMENDATION
1The application temperature is too low. Increase the temperature to at least 120°C (250°F). See the Hotfix Selector table for further assistance.
2Uneven distribution of heat on the heated surface. Check the temperature with a temperature measuring strip or a laser measuring device, and set up the heat press again.
3The application time is too short. Increase application time; it takes longer for the heat to activate the Hotfix glue on layered fabric and seams; if necessary apply from the front. See the Hotfix Selector table for further assistance.
4The pressure is too low. Thick fabrics and certain products need higher pressure. See the Hotfix Selector table for further assistance.
5The heat press does not close evenly. Adjust the heat press.
6The ironing pad is unsuitable. Carry out tests with different ironing pads to establish the most suitable.
7The temperature is too high. Choose a lower temperature, between 120°C and 170°C (250°F–340°F). See the Hotfix Selector table for further assistance.
8The application time is too long. Reduce the application time. See the Hotfix Selector table for further assistance.
9The pressure is too high. Reduce the pressure on the heat press. See the Hotfix Selector table for further assistance.
10The ironing pad is too hard. Use a soft silicone pad.
11The fabric is extremely sensitive. Iron the fabric with a steam iron.
12The transparent support film leaves marks. Cut away more of the film, closer to the edge of the motif, to reduce marking.
13Hotfix elements are not being affected by the heat plate. Balance out the different thicknesses of seams, buttons, zippers etc. by using pieces of felt, which have been cut to exactly the right size and placed under the Hotfix element.
