We'll take you through the steps involved in injecting a tyre sealant. But before we start, we should point out that tyre sealants may contain chemicals. Be sure to follow the recommendations for protection (eyes, hands, clothing, etc.) given on the box before handling them. And in the event of accidental spillage of tyre sealant on your clothes, clean up the stain immediately to preserve their lifespan.
1/ Check the expiry date
Before using tyre sealant, make sure that the product has not been used beyond the expiry date indicated by the manufacturer. Sealant loses its effectiveness once it has been in contact with the air, particularly after several uses. Using an out-of-date tyre sealant or one that has been used several times is likely to give you a poor experience.
2/ Remove the wheel
Although it is not imperative, we recommend that you remove the wheel before injecting. This makes handling easier and allows you to distribute the tyre sealant more evenly.
3/ Give the bottle a good shake
Tyre sealant is made up of several components: water and denser particles, e.g. latex or polymer. It may also contain natural or chemical solvents. To ensure that the tyre sealant is effective, it is important to shake the bottle well before injecting it.
4/ Unscrew the top part of the valve
