Flex Seal Reviews

We have a drippy gutter over our pool pavers. My husband tried Flex Seal spray and tape. Neither worked AT ALL. My neighbor had the same problem and tried both products as well with the same results - neither product worked. We both came up with the same solution - a small wastebasket under the drip to catch the rain.

We purchased $100 worth to seal up our water leaks in our bathroom. It only worked for three days and the water leaks got worst. Would I recommend this product to anyone? Not a chance. The advertisement is false. As far as, As Seen on TV, it is complete BS. I have seen it in our Walmart and Target stores.

This product is complete garbage. I tried using it on my air mattress (just moved into a new place with a boyfriend, I’m 8 1/2 months pregnant) and the mattress had a few holes in it. So we used it in our room with a giant window opener and a couple of fans going to air it out. Of course, it’s going to smell the first few hours, maybe a day after, but I never expected it to be almost four days of this horrific chemical smell It just will not go away. And to make it worse, it didn’t even work! I contacted customer support and asked how to get this awful smell to leave and no reply. Screw this product, I want my money back.

I bought four cans of the Flex Shot clear to put in the cracks between my patio aluminum roof. It had been a couple of years since I used some flexible sealant, but I had a couple of drip leaks, so I decided to try Flex Shot after seeing the commercials.

I scraped off and cleaned the old flexible sealant and made sure to completely cover the linear gaps (about 1/8") between the aluminum roof pieces (about 100' linear feet). I checked after applying to each crack to make sure I had completely covered the gap. About 6 hours later, we had a short rain (drizzle), and I noticed there were a couple of drip leaks. I would not have spent about $50 on four of these Flex Shot cans just to have the same result as old flexible caulk sealant. I now plan to use some aluminum adhesive roofing tape to see if I can stop these leaks since the Flex Shot was not sufficient; it did not work near as well as the caulk I used in the past (it lasted a couple of years prior to drip leaks).

Flex Shot might be good for other applications, but not for 1/8" gaps between aluminum roofing pieces (the pieces flex with the hot and cold of the day), that is why I had used flexible caulk in the past which is a lot less expensive than Flex Shot and for this application worked a lot better with no leaks for a long time. I suggest not using Flex Shot on patio roofs.

I tried this product on three different occasions; one on plastic, two on rubber, and three on porcelain. It was bull on all three. Somebody needs to stop Phil Swift from selling a swift one. Very unsatisfied.

I NEVER write a review, however, I must say, what a total RIPOFF! This is a TOTAL waste of money.

I purchased and tried it and it WOULD NOT even hold up a little 1-ounce piece for a model I was working on, so I finally went to a hot glue gun.

I just bought the Flex Tape to see if it would stop a couple of pinhole leaks. Yeah right, what a joke and waste of my time and money. It does not work. The water pushes out of the sides as it builds up. I'm very disappointed. And they use this in the commercial where they cut a boat in half then put it back with Flex Tape. Yeah right, how misleading to the consumer. I would love for Mr. Flex Seal to get hold of me.

I had an emergency with a broken pipe so I ran to Walmart and got both. I ran back home and both products failed. I have never been so disappointed in a product. Between the both, I spent $28.00. The tape did not stick. Very sad to say I hate this product.

It doesn't stick to or over DRYLOK waterproofing on a basement wall. Five feet for $13.00 plus tax and not sticking very well was disappointing. It may work for another application, but I wouldn't recommend using it over DRYLOK.

We bought both the Flex Seal tape and the Flex Seal liquid to repair a rubber hose. Neither product worked at all. Water came right through both repairs. I would never recommend this product.

I have used the liquid to seal all the seams in my vintage aluminum boat, and it has worked wonderfully. However, I need to paint over it, and I can't seem to get a paint to stick. I have used a spray paint primer and latex based no slip paint. Neither has worked, it just peels off.

Any ideas on what type of paint I can use?
