Practical First Aid for repairing tire punctures while on the go. Seals flat tires without having to remove them, thereby helping you to get home safely. Not suitable for use on tubes that ripped or cut at the side, or if the tire has slipped off the rim. For bicycle tires (with and without inner tube) from 12 – 29 inches. Can be used for all common bicycle valves (Schrader, Presta valve and Dunlop valves). Also suitable for e-bikes.
Where possible, remove any causes of the puncture first (e.g. nails, screws). Then bring the wheel with the valve into the 12 o’clock position and deflate fully. Shake the can well, screw the screw connector onto the tire valve, hold the can vertical and use the entire can. Then remove the can and wipe off excess material at the valve. Finally, adjust the tire air pressure and take off immediately so that the foam can be distributed evenly. In most cases, a solid plug sealing the hole will have formed after 10 minutes. Depending on the size of the puncture, it may be necessary to pump more air after a few minutes.
