GlueTread Adhesive is 90% cured after 20 minutes and 100% cured after 1-hour.
If you are not interested in waiting, you can purchase a bottle of GlueTread accelerator and apply it to the patch immediately after repairing your tire. This eliminates any cure time and the tire can now be inflated immediately.
Check out the video below to see how it works! (Fast forward to the 3:30 mark to see the accelerator in action)
