    Homemade tubeless sealant.

    There is a huge thread on mtbr.com about making your own tubeless brew. I finally got around to it and so far it works great. I mounted a new maxxis ikon, sealant sprayed out along the rim and sealed within about 20-30 seconds. Stans costs about $128/gallon, the homemade brew costs about $20 gallon. supposedly the OSS makes less boogers. It also stays liquid for longer in the heat. I didnt have a problem with stans, I just felt it was really expensive. My hans dampf with stans on a chinese carbon rim held air for 2 weeks while I was on vacation. So far I have had the ikon on for about 4 days and havent lost a noticeable amount of pressure.

    This is the recipe I used (called OSS for open source sealant)

    Full amount

    16 oz. mold maker ($6.80 @ hobby lobby with 1/2 off coupon)
    6 tbsp ammonia (free - ammonia based windex)
    16 oz. propylene glycol ($2.5 - $20/gallon at tractor supply)
    2 tsp. xanthan gum (free - HEB I think, well expensive but you use so little)
    32 oz. distilled water($.50)

    Order to add:
    16 oz water
    16 oz PG
    2 tsp xantham gum (1 tsp next time?)
    3 oz ammonia
    Mix with drill

    Add 16 oz latex mold builder
    Mix with drill

    Add 16 oz water
    Mix with drill

    the latex is what seals, the ammonia prevents the latex from hardening. As the sealant gets exposed to the air, the ammonia evaporates so the latex can solidify. The propylene glycol is a solvent. Xanthum gum acts as particles.

    The PG is available at tractor supply, hobby lobby has the latex mold builder (use a 1/2 off coupon). For ammonia I used windex with ammonia (couldnt find a pure ammonia + water solution).

    The windex is blue so the sealant has a blue tint.

    Thanks. I have meant to work my way through that thread and pull out the winning recipe, but buying another bottle of Stans just seems easier. Maybe we could have a brew party with a 5 gallon bucket. BYOEmptyStansBottle.

    I've been using it for a while now, though yours is way more complicated than mine. I just use wss version 1
    16oz mold builder
    16oz slime
    32 rv anti freeze
    Blend up and it's done. It works. I even put on an old tire that had a good pinch in it and it sealed it and I rode it at a low psi on the belt and it worked perfect. I'm a total convert.

    rv anti freeze is propylene glycol with additives and diluted. Slime and the mold latex contain ammonia, slime has the chunks and PVA (thckener like xantham gum). Not sure what prices you are paying, but is it more expensive? In any case the goal of the OSS is to have a more pure recipe with completely known ingredients (no additives) at the lowest price

    latex mold - 6.80
    16 oz slime - 10
    32 oz rv anti freeze - $5

    this is about $40/gallon

    If you just need pure ammonia, it's dirt cheap and easy to find at HEB. I think it was in the cleaning aisle when I bought my last bottle.

    I've heard that some of those concoctions will result in giant blisters on your tire and void the warranty. You can keep it simple with latex, a little windex, glitter and water. I actually just use latex and water. More important than the mix is remembering to add a little from time to time!

    Don't forget to add $30 for driving all over town to buy the ingredients... I've had bad luck lately with Orange Seal (not enough glitter) and will be switching back to Stan's and at 74 cents an ounce with free shipping...it's not a bad deal...

    Actually all the places I needed to go to were right next to each other. Spinnincin, I wear through a tire way before any type of blisters show.
    It's cheap.
    It works.
    It's makes a TON.

    I think I will try this. Stan's was fine, OS was great, but all of it seems to co$t a lot.

    My sentiments exactly. Between all my bikes and my wife's bikes I was spending a fortune. This stuff lasts longer and works just as well and is a hell of a lot cheaper to make.

    stans is ammonia (to keep the latex from solidifying), propylene glycol, water, latex and some custom additives which act as chunks.

    Here is the ingredient list from a website
    http://www.jackandadams.com/stans-no...e-sealant.html

    The people who came up with OSS actually looked at the patents to get the ingredients list.

    Ace Hardware "Janitor Strength Ammonia" is the purest (no surfactants, soaps, or other additives) you can easily get. Aquarium guys use it to test their filter systems. I have used the original WSS and now OSS from mtbr.com in my tires for over 5 years and have not had blistering. It is a little more effort than buying Stan's, but homemade is cheaper and performs better in the Central Texas heat.

    Doesn't urine have ammonia?.. it's pure / organic / free.
    I saw a survivalist on tv drink some out of a snake skin. I think he ate the snake earlier in the show, saved the skin to hold his piss, which he drank when he got thirsty.

    The snake skin might be used as a tube if the sealant doesn't work.

    except eyes. i learned this personally when i was first mounting a wtb stout tire to a stan's 29er rim. apparently they dont like going higher than 45psi. ever. so says the thread on mtbr that i read once all the stans/slime/glitter mixture finally washed out of my eyes.

    if you hold the wheel with work or truing stand (i.e. eye level) while you mount/seat/air it, please wear eye protection. and ear plugs wouldnt either.

    and before anybody asks, it only had 50lbs and had been sitting for a minute or two when it popped.
    I am the melancholy beer.

    I'm resurrecting this thread because I'm about to mix up a batch of homebrew. Mine will be the original WSS because I'm lazy and it easier to only go to two stores (Hobby Lobby and Walmart). I tried to skim the MTBR thread, but that thing is ridiculous. 95 pages of mostly BS. The biggest question for me is about the chunkiness. For those of you who have used the Slime, anti-freeze, and latex mix, do you add any chunks? People have commented on glitter, silica beads, dryer lint, pepper, ground up tubes, etc. Also, I bought the regular slime (vs. tubeless silme). The word is that the tubeless version is chunkier. Should I return it and get tubeless or just add some chunks?

    I've looked at that thread too but spilling antifreeze and ammonia seems mean to all the sweet deer or bunnies that might lick it up. Stan’s NoTubes Sealant is environmentally-friendly, non-toxic,
    non-reactive and non-corrosive. or so it says. I enjoy seeing wildlife on my rides. It's part of the experience.
    Grab life by the timbales.

    Don't forget to stop and smell the Rosemary.

    There is no way that homebrew is significantly worse for bunnies and sweet, delicious deer than Stan's.
