Frequently Asked Questions.

Does the tire deteriorate when using the sealant liquid in it?


If you decide to use inner tubes again all you have to do is dismount the wheel, remove the valve, insert the tube and inflate with any issue. This is very practical in cases of larger cuts or holes that the sealant cannot fill.

If you are very careful you can remove the residual sealant liquid with water if it is still wet, carefully scraping with your fingers or a rag if it has dried completely. Only a few flakes of the residual product will come off.

There is controversy as to whether the tires become deformed and the tire brands have rushed to declare that this is because of the ammonia in the sealants. Since our sealants do not contain ammonia, any deformities cannot be caused by ammonia when using our product.  Moreover, when testing two different tire brands with our sealant, there have been cases where one tire has become deformed and the other not. Therefore, we have to conclude that this issue is with the tire itself and not the sealant.

How do I refill the tire with liquid when I notice it has dried up?

In the product specs you will find instructions on the different methods to refill your tire with ant-flats liquid.

Each time I refill my tire am I adding more weight?

Consider that the liquid has water as a part of its composition.  As the water evaporates, the weight is the tire also decreases as the dry residue in the product is minimal. Therefore, when you refill with sealant you will be adding some additional grams to your tire by replacing what has evaporated.  the objective is to maintain a certain level within the tire.

How often do you recommend refilling the tires?

We recommend refilling your tires with the recommended refill dose at least every two months; even though the tire has not had any air loss, the liquid inside looses some of its properties over time and needs to be replenished. This means that in case of a flat, if there is little liquid inside or it has dried up the little liquid left will not be enough to seal and repair the tire. Refilling a half dosis every 2 months guarantees your peace of mind, long lasting sealing and automatic repair of punctures en route.

How long does the liquid inside the tire last?

This depends on many factors. If you use tubeless tires it will last longer as these seal more easily meaning the sealant needs to work less. It can last 3 or more months but we recommend refilling before that time as the liquid inside looses some of its properties over time. We recommend checking your tires every two months.

Another factor is climate; the liquid evaporates or dries quicker in summer than in winter.

We always recommend checking your tires and liquid levels a few days before any type of competition.

 To check your tires, dismount the wheel and leave it resting upright so that the liquid drains to the bottom of the tire.  Do this away from noise. Put your ear close to the tire and shake it around in order to hear the liquid moving around on the inside.

How much liquid do I add? I know it will add weight to my tires…

Recommended dose for tires with tubes:

MTB 26”: 80-100 ml per tire.

MTB 27,5”: 90-110 ml per tire.

MTB 29”: 100-110 ml per tire.

Fat bike: 170-200 ml per tire.

Road tire: 30-40 ml per tire.

These ranges or recommended doses should be adjusted to each tire and its balloon factor. For thin tires, use the minimum dose and for thick tires we recommend using the maximum dose.

You can fill with a higher dose, but it does not improve the sealant capacity and it does increase the weight. Check your tires periodically and refill when necessary.

Check your tires periodically and do not allow the sealant liquid to completely dry up inside (it will dry over time as the water in the liquid evaporates and this depends on several factors).

Is the liquid sealant compatible with CO2 cartridges?

Yes, our liquid sealant is totally compatible with CO2 cartridges.

What is the maximum puncture size the sealant liquid can repair?

This is difficult to determine for several reasons; where the puncture is located on the tire, wear on the tire, level of liquid sealant inside, etc. Our tests reveal that the liquid can repair holes up to 6mm.

For punctures and holes bigger than 6mm, we have specific tubeless repair kits in our catalogue for this purpose.

Can sealant liquid for tubeless MTB tires (yellow bottle) be mixed with anti-puncture sealant for road tubes, tubeless and tubulars (red bottle)?

The MTB liquid sealant (yellow container) can be mixed with the anti-puncture sealant for road tubes, tubeless and tubulars (red container) no problem if and only if this mixed is to be used in tubeless MTB tires.

Can sealant liquid for tubeless MTB tires be used for road tubes, tubeless and tubulars?

No, liquid sealant for tubeless MTB should only be used of for MTB tubeless and tubular systems.  It is formulated to work with lower air pressures and is less dense to guarantee a faster flow through the inside of the MTB tire.

Does the liquid sealant damage my rims?

No.  After selling thousands and thousands of bottles of liquid sealant, we have never experienced a situation where our product has damaged any rims whether aluminum or carbon.  However, if you are referring to the valve hole on aluminum rims, we recommend an extra measure of protection by painting the exposed aluminum on the inside of the hole with a similar color or transparent nail polish.

How do I measure the level of sealant liquid inside my tire?

This can be measured with our X-Tube accessory.

If I get liquid sealant on my cloths, can I remove it?

No, once the liquid sealant is in contact with fibres, it dries and solidifies making it practically impossible to eliminate.

How long does a bottle of liquid sealant last once open?

The response to this question depends on a series of different factors: how many times the sealant has been opened, climate, storage conditions, etc. Our recommendation is that once it has been opened and used, it should be properly closed and stored in a cool place away from light.  Under these conditions, the liquid will last longer and in better condition. Our tests have revealed that under these recommended conditions, our liquid sealant will last 2 years in optimal state of conservation depending on climate conditions.  Our experience is that, under normal conditions, once opened, the bottle will normally be consumed before the liquid deteriorates.
