Skilled sealant technicians can use either approach without making a mess. But, for the rest of us it’s easy to get it wrong. If the pointy end of the bottle slips out of the valve for example. Or if you thought you had your partially installed tire on right and it wasn’t. Once the sealant’s in it, if it pops off the rim, watch out!

We also have a guide to the best tubeless pumps and inflators.
