How to Repair a Punctured Tire Using a Universal Patch and STEM Plug

1. Use pliers to remove foreign objects and mark with chalk to identify the injured area.

2. Prepare the injured area by inserting a carbide cutter into it 2 to 3 times from the inner and outer side of tire.

3. Coat with Super Valkarn G CFC Free vulcanizing cement.

4. Apply Super Valkarn G CFC FREE vulcanizing cement to the injury as well.

5. Insert the wire of the STEM to the injury from the inside of the tire.

6. Pull the wire of the STEM with pliers from the outside. Once the tip of the STEM appears, grasp the tip and pull until it has almost but not quite comes out.

7. Cut so that the STEM protrudes 2 to 3 mm in length from the inside of the tire.

8. Adjust the patch so that the injury is in the center of the patch and outline an area slightly larger than the patch. Make sure to match the bead section of tire and bead direction of the patch.

9. Use Liquid Buffer CFC FREE to lift oil and stains and remove with a scraper.

10. Buff the attachment side of the patch with a low speed air buffer.

11. Use an air vacuum to thoroughly remove any scraps and residue.

12. Evenly and thoroughly coat the patch attachment side of the tire with Super Valkarn G CFC FREE vulcanizing cement and let it completely dry.

13. Remove the film from the patch and attach to the tire without touching the attachment side. Make sure to match the bead section of tire and bead direction of the patch.

14. Pressure bond with a milling roller from the center outwards to prevent air from entering the patch.

15. Cut the STEM on the outside of the tire so that there is still 2 to 3 mm in length protruding. Using Sealiner CFC FREE to finish will ensure a more thorough repair. The repair is complete.
