Flex Seal Reviews 

Clean and followed instructions correctly use to fix my husband car hold our carpet down put glass back together waited the correct time for it to bond together absolutely love it worth every single penny I spent on it

We used it to coat my bay window area when a new roof was put on in April 2022. In December 2022 the area leaked again and my roofer went up to look at it and it had cracks all thru where he had put the FLEX SEAL. He said it was a bear to work with and he would never use it again. I will not recommed this product to anyone.

Absolute GARBAGE!!

I bought two cans of the spray rubbish with the intention of using it to spray a home made feral cat shelter so it was water proof ... yeah, right. After shaking the can for a good length of time it sprayed out in a single JET and was as thin as water - the crap went every where and was nothing like what I expected. I don't know how that idiot Phil Swift can sleep at night advertising this stuff. Total garbage, Total waste of money!!!

First let me say I'd rather pick "0" stars compared to the one but wasn't given that option. Bought Flex Seal to patch a water trough around the bottom. Applied it at least 3 times waiting anywhere from 2 days to longer to put each application on. Finally I put it out yesterday and filled it. Immediately leaks shot out THROUGH the Flex Seals. For a product you can supposedly seal a window screen with and ride as a boat this is a worthless product - I've had bathtub caulk last longer. Only wish I could get my $15 back but that's doubtful. I will end this with DON'T WASTE YOUR MONEY.

A brand new 3 lb unopened tin was half cured once I opened it. I dug a hole in the soft spot where the foil seal was in contact with the top of the sealant. What came out was full of lumps and would not stick to the surface I needed to seal. Since it was purchased at the beginning of the summer, I no longer had the bill to return it to the retailer. Expensive lesson...

I wouldn't even give the flex seal tape one star. Hard to cut and would not stick or even stop a small pin hole leak in my pool. Dont buy it find another product, and dont trust the positive reviews and claims there more than likely false.

I used flex shield tape on my leaking garden hose today.
The flex shield tape did not stop the water leak !
The flex shield tape is also difficult to use, I had to use several types of scissors and even after I found a pair of scissors that would cut this tape, the tape was still difficult to cut. I thought about using a knife or utility knife ! I bought this flex shield tape against my better judgment because I previously used flex shield glue to try to fix a pipe leak that also did not work ! I am now out the cost of the flex shield and I have to buy a new garden hose. This is a bad product, I will never buy this product again and strongly recommend that anyone thinking of buying this product not to do so !

HORRIBLE product! And every time I talk to someone about it, they say the same thing. We had a leak in our fountain and my husband has the patience of a saint and did 3 coats, letting each one dry in between for 48 hrs . . . didn't matter, leaked the very next day. Again, everyone else that I have talked to had a bad experience with it and it did not work for them either.

Terrible product. I had a pin hole leak in my pressure washer wand, so thought I would try sealing it with this until I could buy a new wand. I waited one week to let it sit, and try using it. It didn't last for even 30 seconds. The ads are definitely misleading. Returned to the point of purchase for a full refund. Don't waste your time buying this.

I'm going to be 100% up front here. The only reason why I even bothered with this product was because I was very desperate.

There was a massive storm coming in and the last time we had rain our roof had a massive leak in it. We were able to tarp it but wanted to get it properly fixed.

Unfortunately we discovered we couldn't finance a new roof and didn't have the money or know how to get it done on my own.

So the day before the massive storm was going to hit us. I went to the local ACE and bought 2 cans of Flex seal. Never in my life have I felt so desperate. I didn't believe in it and thought it was a complete waist of time.

When I went to bed that night I set up the buckets and had the tarp ready as I full expected to have to put it back on in the morning. Because there is no way this is going to work. The cheapest est I got from a local roofing company to patch it was $2,500.00 usd. There is no way $30 worth of TV snake oil was going to get the job done.

I used both cans applying it to the seams of each tile in the effected area. I didn't have enough to give it a second coat. I did the best I could with what little product I had. Again completely believing that this is not going to work. But I had to try something.

Well, It worked! I woke up the next morning to a dry home. Although the storm isn't over I have no reason to believe that it's not going to last.

This stuff is amazing and I'm completely blown away by it's ease of use and effectiveness.

It's worth trying out!

Ordered paste product. Didn't use for maybe four months. Product was maybe twenty five percent solidified. Resealed via directions and one week later was more than fifty percent solidified and used small amount. Two weeks later and was totally solidified. Got about one dollar use from thirty dollar tub.

MY NEWEST EDITED REVIEW OF FLEX SEAL PRODUCT
( THIS has been edited by myself
04/14/2021 )
I 1hammer1 am changing my negitive review of FLEX SEAL Liquid 128-fl oz Gray Dip Rubberized Coating.
The day that I published my negitive review of this product THE FLEX SEAL COMPANY called me at home and offered a solution to my problem with the grey color WOW they wasted no time they have made me more then happy ( WHAT A GREAT COMPANY ) I have always liked their products the FLEX SEAL Liquid 128-fl oz Gray Dip Rubberized Coating is a great water proofer we have had water in our basement when it rained hard. We have done our whole basement walls and floors with this product this product will and does stand up to hydrostaic water pressure if it is appied in 2 to 3 coats we were told it probably would not stand up to normal foot traffic in our basement (NOT TRUE) we have scooted and pushed and walked all over the floor no problem unless you really scape hard on the floor but you have to apply this product properly clean the surface have no loose stuff and dry and apply 2 to 3 coats let dry well 2 to 3 days between coats also venilate the area well. We had basement waterproofing estimates between $30,000.00 and $42,000.00 this product cost near $100.00 per gallon and we purchased 29 gallons from 1 source and 8 gallons from another sourse total =37 gallons est. cost $3,700.00 ( WOW BIG DIFFERANCE ) My wife and I are 80 years old and we did all the work by our selfs we just took our time also after the 1st coat you do not have to wait till it is not raining because it stops the water from coming in apply more coats for stronger protection and longevity I truly do recommend this product and truly recommend the FLEX SEAL COMPANY and special thanks to

I am responding as you ask me to do. We have purchased 29 gallons of FLEX SEAL liquid 128-fl oz grey dip rubberized coating (2-pack ) and single gallon purchases from Lowes and 8 gallons from home depot for our basement floor and basement walls, your product required 2 to 3 coats to stop leaks after I had already sealed floor and wall cracks with another self-leveling crack sealer product. The problem that we are having that is upsetting us is the floor has 3 different shades of grey everywhere all over the floor where 1 can left off and we started a new can ( all gallons cans is all we have ever purchased ) also it is the same thing on our basement walls if they had been one color everything would have been fine but that is not the case. Wow after spending almost a $100.00 per gallon and to end up looking like this with all that work and hard work it is. your product per gallon does NOT go very far. why can't you make only one shade of grey is our question, once we started this project we had to finish it even with the different shades of grey. We are so disappointed with your product we wish we would have not trusted you and your product, if is applied the proper way I believe your product will stand up to hydrostatic water pressure but it has to LOOK GOOD ALSO for that kind of money .

We are now sorry that we purchased your product we will never purchase any more of it or any of your products, and we will never recommend any of your products. Lowes and home depot have all of our purchases of your product I paid for your product with my Lowes and home depot credit card, after reading your blank Incident Report form you want me to fill out ( OUR FAMILY, FRIENDS , NEIGHBORS, ALL LAUGHED ) And we all said never again.
WHAT ( B-S ) Wow what customer service you have good luck with that, and now after reviewing your product we are hearing from others with all kinds of complaints about your product from others we never heard of wow. only been sent to our email so far. ( IS FLEX SEAL SOME KIND OF SCAM ) We purchased your product in good faith only to get a bunch of excuses and I know you know that you have a grey color problem. ( if you cheat me the 1st time it is your fault but if you cheat me the second time it is my fault.

( And all we wanted was to know was how to fix the color problem we have tried to fix it with more grey @ $100.00 a gallon but even the same (batches of gallon cans) are all different grey colors LIGHT, MEDIUM, DARK GREY )

Have a great day

PS THE PROOF IS IN THE PUDDING.

Thank you

Placed an order for 2 rolls of the 12'x10' tape on 28 September.
On 29 September, received an e-mail claiming the order had shipped, via FedEx. Tracking number was given.
I live in Northern NY State, about 100 miles from the capital, 40 miles from the nearest "large city" so the delivery route used is, to me, disgusting:

On 29 September, my order left Georgia.
30 September, it arrived in West Virginia.
01 October, arrival in Massachusetts where it sat until...
05 October, it appeared in a town only 100 miles from me in NY and was THEN sent to a town in Connecticut... 250 miles away!
07 October, TWO DAYS later, it's still in Connecticut with a delivery date of...
13 October!

In addition to this FedEx information I see that my order will be handed-off to the USPS. My experience with this method of shipping has never been positive. (UPS has a similar "service" and ALL of my orders that were "handed-off" to USPS have arrived damaged. Not so with ANY shipments handled strictly by UPS.)

Contacting FlexSeal is useless because they deflect responsibility to FedEx and contacting FedEx is useless because they say, appropriately, that the "Shipper" chooses the method of shipment (the "hand-off").

The "FlexTape" isn't cheap (inexpensive), and what makes all of this worse is that the delays have now put me in a position where, by the time the tape arrives, it will be too late for me to make any use of it for the purpose intended. I now have to invest added expense in time, travel and money to (hopefully) find a reasonable substitute for a product I was assured would be my best bet. So it's costing me MUCH more than I've already spent in time and money. And "support", "assistance", basic concern? Apparently none. I've tried sending e-mails to "Flexsealproducts"... 2 out of 3 have been "returned" as "undeliverable".

I most certainly would advise: If you can't get it at your local retailer, find an alternative. (Personally, I'll NEVER buy another "Flex" product, no matter where it's available nor the job to be done.)

One of the best memes to exist. Phil is a madman.

I placed my order with Flex Seal on 7/27/2020. After two weeks I did not receive a confirmation from Flex Seal nor did I receive my product. I sent several emails to the company and all they said is that they received my order. They indicated that it will take 30 days from the date of the order. This is absolutely unacceptable and I write this posting so "consumers be aware". If you are not in immediate need of this product (Flex Seal Paste), then order but be prepared for a long wait.

I used Flex Seal to patch, bond, seal and repair my depression. To show you the incredible power of Flex Seal,

I sawed this review in half.
