    Have others had problems with homebrew formulations containing ammonia eating through the adhesive on various tapes? I've Gorilla Tape, Gorilla Clear Repair Tape, Chemtape (chemical-resistant duct-tape), strapping tape, and a few others fail on me using my Latex/PG/Windex/water/slime formulation.

    It seems that many folks are using formulations without ammonia, so the question is WHETHER AMMONIA IS BENEFICIAL, or does it just result in me re-taping rims every month?!

    Been running ammonia-based homebrew for several years with no issues ever with my tape - both Stan's yellow tape and Gorilla.

    No problems with tape and ammonia, maybe scrub your rims with a solvent, alcohol, and soapy water.

    I have been running tubeless since year 2000.

    Have tried most on the way to a perfect tubeless setup.

    Started like most with latex based sealants.

    They dry out and stop sealing pretty fast if you live in a warm climate.
    They also ruin clothes and whatever they get on (when you get a hole in the rear tyre and continue riding you get a nice pattern of latex on your back if the hole is not very small.

    Like most I started out with rim strips and kits from Stan and Swiss and a couple of other similar inferior products. Did not know better.

    Now I ride with real tubeless wheels, real tubeless (not tubeless ready) tyres, use latex- and poison- free sealant that is not drying out but last as long as the tyres do.
    That way I spend more time riding my bike and less messing around with getting the rims airtight, getting the sealant to cover too thin side-walls, which is really time consuming.

    Latex is good for doctors and nurses gloves and probably a lot of other things, but for sealing tyres is sucks.

    If you live in the US try Quadboss ATV sealant, it last the lifetime of the tyres, if you live in Europe there are now so many making latex free sealant that you can google and find them.

    If you want to save a few bucks and spend a lot of time mixing and experimenting: Good luck.

    I just want to spend my spare time riding my bike.

    No.
    Try latex free sealant from Quadboss. Will not dry out and will seal most holes and last liquid till the tyres need to be replaced.

    Has anyone else tried this Quadboss sealant? I'd love a sealant that doesn't dry out.

    Yeah. 5 years.
    No mess,
    no mixing,
    no waste of time trying to get a formula right,
    no sticky latex on clothes,
    no latex that dry out and need to be replaced (after a while the dried out sealant will be heavier than than the wheel),
    no fun trying to find a formula that is better than the companies that work with sealants professionally are doing.
    Lots of reasons to do what you like the most.
    Me: I like riding my bike more than mixing sealants!

    Anybody have dried out sealant in tires that weighs over 1450g? How about over 1000g?

    I have had a tire for a few years that in the end weighed ~100g more than it started with from dried sealant. I was shocked.

    Effetto Mariposa has a prototype powder that is added to its Caffe Latex tire sealant. This additive allows for better sealing of larger punctures. It’s a similar concept to other tubeless solutions that feature additives, but the V-CL additive is not packaged with the Caffe Latex in order to facilitate easier installation. While it may work with other sealants, representatives were quick to note that not all sealants are created equal, so use at your own risk. Some sealants, for example, contain ammonia, which doesn’t play nice with the V-CL additive.
    Yep. with CaffeLatex I had a hole in the rear tire and got a long pattern up the back of my jersey. It never got off.

    I am sure you are right. Everybody is right about something. What you are right about you may know or not know.
    I am here because I saw somebody asking if all sealants are sticky and I answered.
    I do not know what “really mtb” mean for you. Maybe you can tell me the secret words you use to be a real mtb’er.
    I used sealants from when it was a new thing (1999) because I was tired of changing or fixing tubes and back then latex was the only thing to use. Latex will dry out and stop closing punctures; still most of the “real users” of sealants use that kind of amateur stuff in their tires. Latex will harm some tyres and some paint types and also some of the types of material rims are made of.
    If you are the little chemist trying to make a new kind of sealant and improve what Stan and the others are doing: Good luck.
    I prefer to ride on the trails in the mountains with thorns and lava and rocks that to try to destroy to my tires and prevent the sealant I have in them to stop sealing the holes I pick up on my way. If you prefer mixing things that could be poisonous and harm the environment that some of us want to enjoy unharmed instead of riding that is your choice.
    Then again, what do I know, I am just an old guy riding my Mojo and the worst is that I am still on 26” so you are right. I must know nothing.

    That is right. Most will have worn out the tires long before that could happen. Exaggerate if you want to make your point.
    Still latex dry out, stop sealing holes and when you add new the weight will increase. I use a bit less than 200ml Quadboss sealant and when my tires need to be replaced the stuff is still liquid and will still seal holes. Get latex on your clothes and it will never get off again.

    Adding 200ml to a tire is ~6.75 ounces. No wonder you do not notice it drying.

    My home brew of 1 part latex and 3 parts windshield washer fluid seems to work on my road bike, fat bike and all in between. I experience ~ 50% evaporation/drying over 6 months, from a 3.5 oz dose in a 4" fat tire.

    I just tried making up a batch of wss (1pt mold builder, 1 pt slime, 3 pts rv pg) and put 4 oz in each tire. I have Nates with fatty strippers. After 3 days the bead is still foaming and seeping out a clear looking liquid. I didn't have any seeping like this with stans. Is this normal?

    The rv pg is 30% PG and 70% water

    ^Have you been riding it? Because that can go on forever, with any sealant, if you are just letting it sit. Important to get everything seated properly by riding, especially a new install.

    I hope to get out and ride today. I've just been doing the Stans shake and keeping them inflated.

    I've got about 30 miles on it and a couple of weeks and this stuff is still bubbling out of the bead and weeping clearish liquid. I've got to air it up before every ride.

    Are you positive the bead is set?

    11psi front, 12psi rear (no snow yet and I'm a heavy rider so I run a little higher) and the bead is set all the way around. The tires had never been mounted tubeless and the tires and rim were cleaned prior to mounting. This is the 3rd set of tires I've setup tubeless and the first with home brew. The other two were with Stans and I didn't get any bubbling or weeping of any kind from the bead on those so it was odd to me. I put another 20 miles of singletrack riding on and now I'm getting small puddles of greenish clear liquid on the floor after riding and letting it sit overnight. I can press on the tire near the bead and it will foam and bubble where I'm pressing. The bottle I mixed up isn't separated and the latex is mixed up and not clumping so I wouldn't think it would be a problem in the tire.

    What he said, although I think the type of sealant used is at least partially irrelevant. The bead shouldn't be leaking as badly as it sounds it is even without sealant. I don't think the bead is set all the way. I'd up the pressure to just under recommended limits of your rim/tire to see if the bead pops in.

    They were aired up to 25psi at time of mounting and for two days after I initially set them up tubeless. Air them up and do the stans shake and come back a few hours later and do it again. The bead is popped all the way around. I ordered some other sealant and am going to clean and remount these and see what happens.

    Pic is whats on the floor after sitting for a day or two after riding.

I still keep on using a combination of course corn meal plus dog hair (Jack Russel) as chunkulators. I believe the hair provides the matrix for the corn meal to settle and plug big holes. All chunkulators suspended in the mix by a small amount of XG. It plugged really big holes.

    I think the hair works as well. Unfortunately, we now have two rescue Greyhounds and they don't shed for shi|t so I'll be forced to start using my ball shavings at some point in the future... Luckily, the Dane shed like mad so I've got lots. May have an Irish Wolfhound in the future so those hairy beasts have GOT to shed some!

    Niagara is selling Slime's new STR Premium in 1-gallon form for about $30.

    https://www.niagaracycle.com/categor...-gallon-w-pump

    Their picture isn't right, but based on a bit of sleuthing, it's the right stuff. I haven't tried it. I have watched their PR people and Seth poke holes in tires and have it seal instantly, so I bought some. Cost is $0.25/oz, similar to DIY. Stan's is about $0.75. Orange Seal is over $1. Even at regular pricing ($65ish), Slime undercuts everything else.

    I was using TruckerCo, which is about $0.60/oz. It doesn't seal, dries out quickly, and tends to form fluff balls. The inside of my tire looks like dried oatmeal: lumpy and porous. It's also about 60g heavier than it was new and the latex layer doesn't peel off in one piece like Orange Seal. Not impressed.

    Here's to hoping STR lasts a little longer.

    Thanks.

    I was thinking of giving the Trucker Co a shot as I can get it cheap, but will pass.

    That Stan's looks like a good deal. But, Stan's seems to have issues with shelf life - as least they did. That's what got me to go to home-brew years back.


    If I knew shelf life was not going to be an issue I'd buy that large batch.

    reading MTBRs promo for new Finish Line sealant. i'm a homebrew guy...how can they make something that never dries up but still seals? Just seems almost impossible.

    looks a little thicker, kind of like old school slime.

    You gotta be able to read between the lines, so to speak. When you read a review that claims "this bike climbs like a 25# XC bike and descends like a 200mm DH bike" do you believe it?

    My guess is they are grading on a curve. They claim it lasts the life of the tire. For me on DHF/DHR II DC TR EXO tires at maybe 25 miles a week that's 6 to 9 months. Their claim will never hold true. Some guys will be riding thinner, softer tires and will ride 25 miles a day, 5 days a week and the sealant may well last the life of the tire.

    Has anyone figured out what is the new Finish Line sealant? Sounds like the old-school Slimes from the '90s.

    Just mixed a batch I cut into two:

    Base:
    32oz water
    32oz PG
    16oz mold builder
    5 oz ammonia

    Mix A:
    1/2 cup rubber crumb
    1/4 cup crushed water beads
    1/4 cup corn meal
    1 tsp xantham gum

    Mix B:
    1/2 cup rubber crumb
    1/4 cup corn meal
    1 tsp xantham gum

    I'll put one in each tire and see if either performs better or worse than the other...

    Supposedly it doesn't clog valve cores AND it seals holes...

    The finish line stuff got bad reviews just look it up. No point in trying to make a copy of that. Has anyone figured out how to make orange seal?

    I'm sure we've all wondered how well OSS stays preserved...
    I took a cornmeal OSS batch from 2016 off the shelf. Last year I had made a batch with different chunkulators, but I had to keep looking at the unfinished batch - and it was really annoying me!
    I did float enough ammonia on top to provide a barrier and when I mounted and brought them up to pressure the tires sealed just fine. No issues - that's the easy part.

    After one ride the stuff seems to be A-OKAY. I'll check back in after several more rides.

    1/2 cup rubber crumb
    1/4 cup crushed water beads
    1/4 cup corn meal
    1 tsp xantham gum

    Mix B:
    1/2 cup rubber crumb
    1/4 cup corn meal
    1 tsp xantham gum

    I'll put one in each tire and see if either performs better or worse than the other...
    I would be keenly looking forward to the result of your mix. My earlier experiment with tyre crumbs was a disaster.

    My last attempt with the rubber crumb was pretty good except that it boogered more heavily than others...
