oh i figured you were mounting new tires not used. the sealant is supposed to seal the hole quickly while you ride anyway, so unless it's a big hole which would need a repair anyway, spinning it in the stand a couple times should be sufficient. if you are letting it sit the sealant is just pooling around the portion of the tire facing down. it is actually good to ride the tire immediately to distribute it before it pools in one place by sitting still.

oh and i learned the hard way NOT to pull larger things that puncture the tire out while you're riding. the sealant is doing it's job and sealing around the goathead or whatever it is. if it's big enough a good hole will never seal with sealant alone and you'll just have a flat unless you take it off to repair. did this on a bikepacking trip one time don't know what i was thinking it was a mess. unless it's like a nail or something that requires immediate plugging
