Using the Muc-Off No Puncture Sealant is easy. First, make sure your tyre is tubeless ready or UST. Remove the valve core from the tyre valve. Then, pour the 140ml of sealant into the tyre. Replace the valve core and inflate the tyre to the recommended PSI. Give the wheel a spin to distribute the sealant evenly inside the tyre. When riding, if you get a puncture, the sealant will automatically seal it up. As for maintenance, check the sealant level every few months. If it's low, add more sealant. Keep the tyre clean to prevent dirt from affecting the sealant's performance. Also, avoid exposing the sealant to very high or very low temperatures for long periods as it may affect its effectiveness.
