SEALANT FAQS AND TIPS

Can I use Stan’s Sealant in other brands of tubeless rims?

Yes, our sealant can be used in any tubeless application, including UST. Please follow your rim and tire manufacturer’s guidelines regarding the use of sealant.

How much sealant should I use?

For a XC 29er tire (2.0-2.2”) we recommend 3-4 ounces (89-118ml) of sealant as a starting point. The amount of sealant can be adjusted based on the volume of the tire. More sealant can also be added if a tire is particularly porous and difficult to seal. For road and cyclocross tires, we recommend 2 ounces (60ml).

Can I add sealant to my tubes or tubular tires?

Yes, if the tube or tubular has a removable valve core. If there are two opposing flat surfaces just below the top of the valve, you can use our valve tool to unthread the core and sealant can be installed. We recommend injecting 1-2 ounces (30-60ml) of sealant into tubes or tubular tires. Sealant will not damage tubular tires.

Why is my tire weeping/leaking sealant?

This is the natural process of the sealant evaporating. It is more evident in some tires, but is nothing to be overly concerned about. This “weeping” does not impact the effectiveness of the sealant. The weeping will dissipate as the sealant seals the casing of the tire. More porous tires may require a sealant refresh shortly after the initial setup.

How long will the sealant last in my tire?

The sealant should last an average of 2-6 months depending on factors such as: temperatures and humidity in your area, how often you ride, where you store your bike (cooler is better), tire casing thickness, number of punctures the sealant has already sealed that you never knew you had, etc. A good preventative maintenance schedule for most riders is to check/refresh your sealant quarterly (every three months).

What is the sealant shelf-life?

Stan’s Sealant does not have an expiration date and will last many years in the bottle. Sealant bottles should be kept tightly sealed, and stored in a cool, dry place. Sealing crystals can settle, so be sure to shake the bottle thoroughly before use.

Will Stan’s sealant freeze, at what temperature?

Anti-freeze agents allow the sealant to be used in environments as cold as -20°F (-28.8°C)

Do you add ammonia to your sealant and it is bad for my tire and or rim?

We use natural latex in our sealant and a small amount of ammonia is added to natural liquid latex as a stabilizer when harvested. While there may be a strong smell when initially opening your bottle, this trace amount of ammonia will continue to off-gas over time and the smell will fade. This very small amount in our finished sealant formula will have no damaging effects, even after years of use. Although our Yellow Tape may not be necessary to seal your rim, you may add one layer to protect un-anodized or scratched areas of your rim from oxidation due to moisture in the sealant. Our MSDS can be found on our Tech Docs page.

Will using your sealant void the warranty on my tire?

Stan’s Sealant will not damage your tire, however the use of liquid sealant may void the tire warranty on some models with certain manufacturers. Please consult your tire manufacturer’s warranty guidelines.

What is Race sealant?

Race Sealant is the race-day variation of our popular sealant. While Race Sealant uses the same liquid base as our regular sealant it contains twice the particulate mix as well as a special XL crystal that isn’t used in the standard formulation. These additions allow the sealant to seal larger punctures and keep you racing. As it is made for race-day use it does require more maintenance: Race Sealant should be inspected more often than standard sealant, approximately every 2-3 weeks. It also cannot be injected through the valve; you must break the bead and pour the sealant directly into the tire.

Can I mix Race Sealant with your standard sealant?

Yes, our two sealant formulas can be mixed.

Do I need to clean the sealant out of my tires?

It is always good to wipe excess sealant out of your tires if you plan to use them again. A dry rag is sufficient for cleaning out regular sealant. Race Sealant must be rinsed out of the tire with water after use and then wiped with a rag. If allowed to dry, excess Race Sealant can cause the casing to stiffen, thereby affecting the performance of the tire.

How do I get sealant out of my clothes?

Rinse any spills with cold water right away; do not let the sealant dry. We also recommend pre-treating or washing with a surfactant-based detergent such as Tide as soon as possible. Unfortunately, once your clothing is stained it will most likely not come out.

Is Stan's sealant compatible with CO2?

CO2 is best used in an emergency situation. If you have no other means to get your tire to seat, you can use CO2. However, we recommend that you let the CO2 out either after your ride, or after setting up your tire, and replace it with regular air. Prolonged exposure to CO2 can cause the sealant to separate and/or decrease the life of your sealant.
