93 customers mention59 positive34 negative

Customers are mixed about the leakage of the sealant. Some mention that it works great, it seals a surface and slight sidewall leak in a matter of seconds, and it's an excellent solution to repairing slow leaks in the tires on a riding mower. However, others say that it still leaks, and traditional plugs failed to seal.

"...It sealed up both tires on the first try with no subsequent leaks!..." Read more

Customers are mixed about the durability of the sealant. Some mention that it held up all season, while others say that the plastic tool on top broke first time used and the internal two-piece pump shaft blew apart.

"...The only bad thing I have to say about this is that the plastic stem remover is trash. You can buy a cheap 2 dollar metal one." Read more

"I like the product, not a fan of the packaging, broke off and I had to work the broken piece out to fill the tire." Read more

30 customers mention18 positive12 negative

"Performed as listed! Saved a bunch of money not having to buy and mount a new tire." Read more

"...This crap is a sad joke. DO NOT USE!" Read more

Great Product! It works!

Reviewed in the United States on April 15, 2024

Size: 1-GallonVerified Purchase

I used this on my side by side which had a front tire that was going flat and also on my wheel barrow which had been leaking for years. The Gallon came with the tool which was unexpected. Great instructions and packaged well for shipping. This fixed both my trouble tires and am super happy with this product. I'll buy some more for my new UTV for sure.

Works great!

Reviewed in the United States on April 9, 2024

Both front zero turn mower tires were going flat weekly, despite many attempts to reseal the bead on the rim, etc. Nothing worked. Very frustrating.

Didn't want to buy run flats as they seem to develop flat spots when sitting.

Fix a Flat is well known for rusting out rims from the inside. Been there done that.

A friend recommended Flat Out as it can seal even larger holes, and is not supposed to have any adverse effect on the inside of the rim over time.

It sealed up both tires on the first try with no subsequent leaks! Hope it keeps working but so far I am very happy that I don't have to deal with flat tires every single time I go to mow!

Works well. Surprisingly easy to install. Only complaint is the huge difference between recommended volumes according
To tire size. The bottle says one volume on the back. The detailed instructions said a much higher volume. Net effect was needed two large bottles instead of one.

Fixes almost impossible leaks

Reviewed in the United States on April 9, 2024

Size: 1-GallonVerified Purchase

I bought this to use in an old tractor's tires that were splitting. Some of the splits were an inch long. I just use this for driving around the yard cleaning and didn't really want to spend money on new tires and this stuff sealed the splits. So far the tires are holding air even with all the holes and splits that are in them. Super happy with this stuff and now I need to find the right one for my mountain bike tires.

Mixed Experiences, Overall Positive

Reviewed in the United States on April 27, 2024

Size: 1-GallonVerified Purchase

I put this into the tubes of a new E-Bike following the guidance provided on the product. I then reinflated the first tire and promptly blew the tube, what made it worse was it was the rear tire requiring a trip to our local bike shop for a new tube (hadn’t ridden it a mile at this point). I then added half as much of this to the new tube and inflated in normally. I don’t know if the tube was bad and that’s why it burst or if I added too much of this product, what I can say is half the amount in each tire was good and the tires inflated to 25 psi without any problems. No flats yet and I haven’t seen anything in the tires. Recommend 5⭐️

Best Sealant for eBike 20x4.0 or 26x4.0

Reviewed in the United States on April 15, 2024

Verified Purchase

I've been using flat out in multiple ebikes, 20x4.0 and 26x4.0 tires. I've never gotten a flat. Think about how much time and money this save you, if you were to get a flat. The only bad thing I have to say about this is that the plastic stem remover is trash. You can buy a cheap 2 dollar metal one.

Worked Amazing!

Reviewed in Canada on June 21, 2020

Size: 1-PackVerified Purchase

Flatout Tire Sealant worked amazing! It was very easy to use with absolutely now mess. I followed the directions and it worked perfectly. I had a hole in the side wall of my rear tire on my ride on lawnmower. After putting the product in and driving around for about 15 mins it completely coated the inside of the tire and sealed the hole. My tire has stated fully inflated with no loss of air pressure since using Flatout. I highly recommend this product as it saved me from having to remove my rear tire to either patch it or replace it. Flatout saved me a lot of time and money. Within a few minutes the product was installed and my lawnmower was usable again. I would not hesitate to purchase Flatout again. Thanks
