Stans sealant not sealing. can I add Sand?

Hey guys... here's my crazy idea.
I've had 2 "big" puntures where the Stans sealant wont work at all... seems like its too thin, so it sprays like crazy but wont stop the leak.
I was wondering, what if I add a bit of fine sand to the sealant? wont those sand particles help with the bigger holes in the tire?

Or have you guys managed to add something to improve performance?

thanx a lot

Stick a tire plug in the hole?

Glitter. Works well and doesn't react with the sealant.

Half a pound of sand should do something.

If you fill your tire with cement you can stop all the punctures

capture some eels
take 'em for a car ride, maybe 1 hour in a holding tank
send them back
use the collected eel snot for your tire
No on sand. If you want to add grit to Stan's, you can add some Stan's Race. You can mix Stan's Race and regular Stan's and get the bigger crystals in the Stan's race to plug bigger holes than standard Stan's will. (just don't try to add Race through the valve).

Or mark the leaks with a white paint pen, remove the tires and clean it all out, patch from the inside, and start fresh with Orange Seal.

Corn starch works great to thicken liquid. They use it in the Stan's Pro Race formula. 👌

Good tip. Is corn starch listed as an ingredient, or do you have some inside info?
Bacon strips are great for scenarios like this. If that does not work for me, time for a new tire.

Awesome. Sounds like a great idea. Thanx a lot! I will try that, and add some glitter as suggested aswell!!

I dont know why people are so close-minded and make fun of adding sand. You people certanly are the ones that are guided 100% by the industry marketing, and swallow all the ideas without even asking why.
Adding half a pund of sand (as suggested before) is not what i meant... even thinking about it is more stupid than the idea itself.... how about adding about 5% of the sealants weight?

Im thinking now about adding plastic particles. That should clog the bigger holes, and shouldnt absorb nor react with the sealant.

thanx a lot for those who really answered, and not to the ones trying to make fun

Sarcasm and fun ridicule are the norm here. It gives the place character. Don’t take it personally.

Pre-COVID I was drinking beer with a Tech Rep from Stans at Interbike...when meeting in person to talk bikes was still a thing. He gave me some 411. :geek:

No experience with them myself but, I've heard good results with glitter, and with black pepper. Probably because they are light and remain suspended. Wouldn't sand settle out and possibly clump up in one spot in your tire when parked for a day or two?

Oh, and a thought about the sand; I used to do drywall work and there is a very light sand that is used to add to paint for texture. It remains suspended in the paint better than regular sand. I once bought some cheap texture paint and remember having to lift all the sand off the bottom of the paint can to get it stirred into the paint.

Or… near me out here… why not just buy a new tire?

Or maybe if money is real tight just use a patch kit?

Instead of sand try half a pound of lead shot.

inflate to 110psi.

if it doesn’t seal you can have fun with the projectiles!

Pew pew pew!!!
