OK, here’s the thing … sealant added (Stan’s) followed by disco moves to squish it around. It’s now horizontal and will be left overnight, to be followed by some air.
Now … I seem to remember reading on here that bike should be taken for a wee pootle to ensure sealant has circulated in tyre?
Once the air stops peeing out I tend to go around the block with the tyres at 40psi – forces sealant into any remaining holes. Then leave overnight for it to form a skin inside the tyre and drop to normal pressure to ride.
It already has some air, presumably, and you just intend to top it up tomorrow?
Flip it over a few times with disco moves in between so that both sidewalls seal up. Once you’ve done that a few times it should be fine, although leaving it flat on top of a bucket overnight won’t hurt. A spin round the block should help seal up any bits which aren’t sealed by lying flat.
I would not “top up” but remove the tire, clean out the remnants of the Stan’s sludge and then refill with fresh sealant; you may find a very odd “alien spiky ball” which is what is left of your original Stan’s sealant 🙂
I used to work for the original UK distributor of Stan’s, but after many years of using Stan’s have found Bontrager tubeless sealant (Super Juice?) to be vastly superior to Stan’s, it does not leak or gum up the valves so readily, but stills seals any penetration punctures without issue
as well as finding numerous tubeless valve cores on the market to be superior which have additional ‘o’ring sealing to prevent leakage through the rim valve drilling
and tubeless tape from “Roval” which is 1/2 price of Stan’s yellow tape, stickier and much more secure
OP – if you previously ran the tires tubeless w/Stan’s sealant and they hadn’t been removed from the wheel, all that you should have to do is add more sealant and inflate the tire. You should be able to use them right away.
As said above, sometimes the dry sealant forms a big lump inside the tire. If that is the case, it needs to be removed.
When I ran regular, made for tubes, tires with Stan’s, I usually added about an ounce of sealant to each tire once a month or so. I’m now running tubeless ready tires that are less porous, so I may top them off a little less frequently.
It must evaporate, I’ve removed tubeless tyre and it’s been bone dry inside. The sealant does seem to form a rubber skin on the beading after removal. I just use one small cup full that comes with stans.
Stan’s and other latex sealant dries out over time, sort of like latex paint. If there is no liquid sealant left, the tire should still hold air but won’t seal any sort of puncture.
If you ride regularly, it may just turn into a “skin” on the inside of the tire like a layer of dried paint. If the bike just sits, the sealant may solidify in one clump at the bottom of the tire. Some people have had a booger form when a clump of sealant rolls around inside the tire and keeps getting bigger like a snowball. I’ve never had this happen to me, though.
As far as when to top up; it depends on a lot of things. If the bike is stored somewhere hot (in a car in the summer) the sealant will dry more quickly. Regular (tube type) tires have thinner sidewalls than tubeless or tubeless ready tires. Best case, you may be able to shake the wheel and feel/hear that there is no liquid sealant left in the tire. Some people pry off a bit of the tire to look. I usually just add about 1 ounce of sealant every month or so.
I bought the core removal tool and injector which makes topping off the sealant a very quick and painless job.
