RossTopher Posted February 7 Share I popped sealant in a set of inner tubes in say Oct 2022. I've ridden my bike a bunch without a hint of an issue, but now is my first race in ages and don't want a flat. Is the sealant pap by now? Sludge road sealant (yellow stuff with the Rhino). If it ain't broke, don't fix it kinda thinking, means I don't want to take my tyres off and change tubes for the sake of it. Can I just squirt some more in or am I basically running concrete now?

RossTopher Posted February 7 Share In before comments... I top up sealant on other bikes every 6-12 months and clean tubeless tyres/rims as needed. Its just on the road bike that I have tubes Link to comment Share on other sites More sharing options...
SURFER Posted February 8 Share On road bike I check every 4 months. Using Stans Link to comment Share on other sites More sharing options...
Ozzie NL Posted February 8 Share As I have it recommended procedure is to replace sealant every 3 months fort MTB Not sure about road which uses higher tire pressures and thus might reduce the expiry period (ie need sealant to be less degraded to still plug a hole) Link to comment Share on other sites More sharing options...

I have been using the Rhino pic Sludge since 2016. It has given us some VERY service ! After 18 months, expect to see no more that "milky water" in the tyre. The active sealant has long since formed a layer inside the tyre. NO PROTECTION if you ride over a thorn now. Easiest solution - such out that milky-water through the valve. YES, it is possible to remove the tyre and clean off the balls .... NOT 48 hours before the race .... unless you are 100% sure you have everything to redo the tubeless setup, if anything goes wrong with the removal of the tyre. VERY easy to move the layer of tape ..... Then add your 50 to 100 ml of Sludge and you are ready for the race. PS - Sludge is become expensve, and less and less stores stock it. I have switched most of my bikes over to Enduroseal. Link to comment Share on other sites More sharing options...

I think i am going to take the front off today, feel if the tube is all lumpy now and replace. i dont want to risk sitting roadside on Sat doing a change.

WIPEOUT 1000 Posted February 8 Share Really depends on what product you use or intend using. Most are primarily a combination of latex and glycol plus some form of filler to assist in blocking the hole. Rule of thumb, the higher the latex % the quicker it will seal, but also the quicker the sealant will dry out. E.g. a "race" sealant will seal quicker but also dry out quicker. Josh Poertner from Silca suggest you do a basic shake test, if you can hear it sloshing inside it is probably still fine, if you cannot you need to add/replace.

The thing that got me going on the switch from Sludge to Enduroseal was the gravel bike tyres. Or should I say the higher pressures of the gravel tyres. The Sludge would seal it, eventually .... after spraying out a LOT of Sludge. Enduroseal seems to cope much better at these higher pressures.

SURFER Posted February 8 Share What pressure do you ride? Link to comment Share on other sites More sharing options...
ChrisF Posted February 8 Share 1 hour ago, SURFER said: What pressure do you ride? MTB around 1,5 bar. My hardtail runs on C50 gravel tyres, 98% on tar. I have played around, but mostly around 2,5 to 3 bar. The "Sludge" brand dont like this pressure, Enduroseal works well at this pressure. Link to comment Share on other sites More sharing options...
SURFER Posted February 8 Share Road bike for me, I got 30 mm tyres. Use stans, pressure between 4.5 to 5 bar. At moment no issues. But also depends on the size of the hole that needs to be sealed. Glass cuts is a big issue to seal. ChrisF 1 Link to comment Share on other sites More sharing options...
RossTopher Posted February 8 Share Thanks all. Question was specifically about sealant in Butyl inner tubes. I.e. 25mm tyres on narrow non-tubeless rims. Bit the bullet, put in a fresh tube and added sealant. Quick quick Link to comment Share on other sites More sharing options...
dasilvarsa Posted February 9 Share After 3 months There is just Milky Water Inside the Tyre. It won't Seal Punctures but it will hold pressure well. During my Experiments I've Held Pressure with Tap Water. Link to comment Share on other sites More sharing options...

Or are they special tubes designed to accommodate sealant? Also, what sealant are using, and how much do you put in? And, lastly, does this regime actually prevent flatting if you traverse a shard of glass.? Well, that is actually more than one personal question?

LazyTrailRider Posted February 10 Share It’s amazing how most of you folks keep talking about tubeless sealant, even though the OP more than once said that he’s talking about sealant inside tubes. Two very different setups. I can’t recall a sludge filled tube ever actually stopping a puncture, to be honest… Used it for years and got punctures at the same rate, until tubeless became a thing.

Lazy by name, not by nature! Thanks for articulating my question. I was trying to find the energy to respond with the same info again. Ive had good luck with Sludge over the years, it's just HELLUVA messy if you do get an unsealable. I changed both out in the week, a bit of a waste of good tubes, but hey. Decided to do a little test, Enduroseal in the front and Sludge at the back. All went smooth today LazyTrailRider 1 Link to comment Share on other sites More sharing options...
