Common Troubleshooting Instructions
The patch isn’t sticking.
1.) Try letting it cool a bit more. If the patch is still hot when you’re testing
adhesion, it could come of before it has time to cool enough to hold tight. Please wait at least 10
minutes for the patch to cool. This allows it to set before you test adhesion.
2.) Check your heat and pressure settings. Are they in line with the recommended
temperatures for the fabric type you’re using? Some sporty polyesters, such as baseball uniforms,
have a very high temperature setting needed to get the heat seal to properly adhere.
3.) Pro tip: Try preheating your fabric for a few seconds before adding the patch.
Sometimes, this can make all the difference in the world.
The patch/fabric is discoloring and burning
1.) Use a back heat press. We always recommend using a back heat press, where the heat
is only on the bottom and behind the patch. That way, it's closer to the heat seal, and won't
hurt your emblem.
2.) Check your cover sheet! Barriers such as teflon or silicon can make a big
difference. Have you tried using a silicon pad between the heat source and your patch? This can protect
3.) Experiment with application times. You could be keeping a patch under a press for
too long. Try reducing the time and see how the application fares. Please reach out if you need similar
