Replenishing Your Tubeless Sealant

The old adage of all good things come to an end rings true.  No latex sealant is going to be a set it and forget it forever situation.  Making sure that you stay on top of the maintenance of your tubeless set up will make sure that you keep riding instead of being stuck trail side fixing that pesky puncture that would have otherwise sealed.  


Adding Ultimate Tubeless Sealant w/Fiberfoam

You can always add more Ultimate Tubeless Sealant w/Fiberfoam instead of the replenisher, it will just require a quick popping of the bead.  Deflate the tire entirely, use a tire lever to remove a small portion of the tire near the valve, add the recommended amount of sealant to replenish your tire, reinstall the bead of the tire, and inflate.

Adding Sealant Replenisher through the valve

  1. Deflate the tire
  2. Remove the valve core – use a valve core tool to remove the valve core
  3. Rotate the wheel – Move the valve to the 4 O’Clock position to allow the sealant a place to easily go down without clogging the valve.
  4. Draw the recommended amount of sealant into a sealant injector
  5. Press the hose of the injector over the valve with the core removed
  6. Slowly inject the recommended amount of sealant into the tire allowing it to pool at the bottom of the tire
  7. Repeat as necessary to meet recommended amount of sealant
  8. Reinstall valve core with core tool ensuring it is snug
  9. Inflate to desired pressure

    If the sealant in the tire has already dried, will the replenisher bring it back to life or is it too late at that point?

    I don’t know about everyone else but, I am finding that after 1 or 2 months the sealant in my 650b’s has dried out entirely. So, I have to replace the original sealant. Needless to say, that is pretty annoying! And EXPENSIVE!
    So far I have not found it necessary to remove the dried sealant from the tire except in the area of the bead to ensure I get a good seal.

    This comment is to reply to the commenter “Chad Underwood” who was asking what to use to remove old sealant from the inside of the tire and bead…I have used Silca sealant for over a year, I don’t use the replenisher product, every 3 months I remove the tire, clean the rim/rim tape with a rag and alcohol and I clean inside of tire/tire bead with a rubber sanding block that you can get at harbor freight for 3-4 dollars. (People use this rubber block to clean their belts on their sanders to extend the life of their sanding belts). (I cut this block into 3 equal pieces and I foresee one piece lasting forever, I give the other 2 pieces away to fellow bikers). Don’t use a lot pressure but the friction from the rubber block is perfect for getting the dried latex rolling and unstuck from your tire. Saves the pads of your finger tips immensely from getting broken down from trying to rub the latex off. Once everything is clean, I also clean the valve and valve stem, I put the tire back on, set the bead, deflate, pop a bead off enough to pour new sealant in, rotate the tire, pop the bead back on, inflate and shake a little bit then put the wheel back on and repeat for the other wheel.

    I didn’t see instructions to remove the Silca old sealant off the inside tire or from the bead. What do you use for a scrubbing tool and what can you spray on it to help easily remove the dried sealant without damaging the tire or structural integrity of tire? Thanks. I’ve spent over an hour trying to get it off of both tires.
