When using the iCraft Memory Tape Runner XL, the application must be slow and
steady. If you go too fast or if it’s angled to one side, some of the adhesive
won’t come off the liner properly. When this happens, it can stop the runner
from working. We recommend using the runner at a low angle (45 degrees) and
slow speed with no sudden side-to-side movements.
If you've experienced this issue recently, we highly recommend watching our tutorial video to refresh your technique and make sure you are set up for success in the future.
