Sealant 101

Does it matter which sealant you put in and can you mix it? I.e my OHs bike and mine, conversions done at different shops, can I go buy any sealant and top up both bikes with the same?

Does anything need to be cleaned out first?

Probably not, some sealants are similar, latex based etc but considering the relatively small amounts put in a bicycle tyre even if they were similar type of sealant I wouldn't try mix them, take the tyre off, wash the inside of the rim and tyre refit, put sealant and pump.

 

Perhaps a good alternative is to ask the shop that fit the tyres what sealant they used and then buy the same stuff, then it's fine to just top up.

Ascertain what type of sealant was used.You'll need to crack the tyre off the rim a bit to check.

It will either be latex-based (Stan's, Joe's, Caffe-latex, to name a few). These are generally white or cream-coloured, may have an ammonia smell and if dried out will leave a latex skin or maybe even a big snot ball of latex inside the tyre.

If it's a water-based sealant it will be pinkish, grey-ish, lumo green or some other colour and thick and gooey.

Check all 4 wheels, probably simplest to standardise on one type of sealant.

Probably not a good idea to mix them.

hmmm by the sounds of it, mine is  white and he's is green so it definitely different.

 

is there a benefit to latex vs water based? sorry if this has been covered but I didn't find anything in the search.

Got no idea. I just stick to Stans

Been through a few and paid school fees.

 

Order of preference:

1. Stans

2. Joes

3. all other sh!t that either doesn't seal properly or goes watery after 2 months

Tx. I'll have a go at DIY, if it doesn't work I'll be crawling to LBS with proverbial tail between the legs.

worth getting all the bikes in the house standardised me thinks.

Green is most likely "Slime". I've mixed different "white/cream" sealants with no issue. Mixed Joe's with Slime once and was not a good mix, because a gooie slop and sealed nothing.

Perhaps match the sealant in the one bike and then change the other over to that one, then one needs just topping up and the other swopping the sealant completely.

Yeah that's the plan, I'll fiddle with my bike though. Don't want to give the OH an excuse for an upgrade because I "did something" to his bike.

Have had some kind offers of assistance..will have a go and then call in SOS if required.

Hope you have a compressor at home. I struggled big time with a floor pump. Now the tubeless top-up is a 5 minute job for both wheels.

 

I have to agree that Stan's is best (and probably most expensive). I stick to a cheap brand  of the latex kind and check my tires every 2 months. My bikes are stored in very hot garage so even the Stan's dry out quickly.

Um... No.

Just take it to your local filling station. Use the compressor there to seat the tyres. Just get one of those totties that you use to make your valve work on a car valve compressor. First prize however is a home compressor you can use it on your bike wheels, your car wheels you can even respray your bakkie with it!

Things I never grew up wanting to own one day - a compressor :)

 

Once I clean it out to make sure I'm not mixing stuff, I can just top up through the valve no? Don't need to keep seating/unseating? That is what I ASSumed.

Most latex sealants like Stans you can but the slime based ones are normally to thick to get down Presta valve stems, so in that case you need to pop the bead to feed it in on one side of the tyre.
