Patch Application

Patch Application
After you clean and scar the puncture area, apply a thin layer of adhesive to the same area and let it dry. Don’t apply the patch until the adhesive has dried or your patch will fail. If you apply a thin layer the adhesive will take less than a minute to dry.

Once the adhesive has dried, let any air out of the tube and peal the heavy backing off your patch leaving the thinner layer on the top surface. Place the patch over the puncture and apply pressure. Your tube will be instantly ready to go back into the flat tire on the rim.
