Application
Shake the bottle to ensure an even distribution of Hi-Tec Fibre particles. Mount your tyre onto the rim and initially inflate without sealant until the tyre pops into place. Deflate the tyre and remove the valve core. Inject the desired amount of sealant through the de-cored valve. Reinsert the valve core and reinflate the tire to the desired pressure. Go for a short ride to distribute the sealant around the inside of your tyre and rim.

Advised amount per tyre:
- Road: 30-45ml
- MTB 26", Cross / Gravel: 60-75ml
- MTB 29": 100-140ml
- Downhill: 120-140ml

Always add the amount from the top of the correct range when installing new tires. This ensures that porous tires are sealed and there is enough left to ensure a quick seal in case of a puncture.
