Flex Seal Reviews

People who buy this stuff are nuts. I did and I'm sorry I wasted good money on a very substandard product. Phil Swift sure likes to sell junk. I wonder what Jesus thinks about the lies He hears coming from us. I like to keep my friends, therefore, I would never recommend these products.

The Flex Seal tape is hard to work with, and the liquid does not spread evenly without a little extra work. All in all, these products did their job and held up. I had a leak in my roof, that came in the attic than dropped down onto my white ceiling tile. The liquid was used both on the roof and in the attic, the tape on the ceiling tile. Worked great, held up until it was repaired. Yes, I would purchase again and do recommend it.

After following the instructions on both the tape and spray and waiting the time allotted for it to cure...WOW. What a huge disappointment. I spent good money on the purchase only to be hoodwinked. Buyer beware. If it looks good on a commercial, well, you can bet it's not good for the consumer...

My septic system pipe running out my metal roof started leaking. I guess the rub bearish boot around pipe gave up on keeping water out. I used 3 cans of Flex Seal spray on it. Letting it dry each little bit I sprayed before another coat. Still leaked. Never will I buy another can of Flex Seal.

I used both the Flex Seal tape and liquid spray on my RV and it leaked and caused $20,000 worth of damage and I put a complaint against the company and they denied it after I sent both pictures and estimate for the damage. I have informed all family friends and co workers to spread the word and not buy as they don't stand behind their product. They were willing to pay me for the product but give no money towards the damage. DO NOT BUY as it doesn't work and we followed the directions to the letter. Poor customer service and false advertisement! BEWARE of this product!

I have a small wall fountain made of some sort of resin material. It developed a small hairline crack, so I bought a can of Flex Seal. I followed directions very carefully and applied two coats of Flex Seal to the entire inside of the reservoir. After waiting the recommended 48 hours, I was excited to fill the reservoir with water to see if the Flex Seal was going to hold. The reservoir only holds about a quart of water, so not a lot of water pressure. The Flex Seal seemed to have no effect whatsoever. It still leaked at about the same rate as it was leaking to begin with. This product is nothing but junk!

Omg, this product is the best for making a fool of customers! I work for a maintenance company. We bought boxes upon boxes of this stuff to have as back up, but mainly for little tiny drips we would get in a small area. Didn't work. Then we said ok, maybe not meant for what it said so we tried to use for a small hole we drilled. Man, it never even dried over it, it just leaked through the tiny hole before it dried. My company threw all 200 cans away. I took them and tried to give another chance and again didn't work. So I sold 195 of them for $1.06 each can to a little corner store in my area. Every can he sold was an angry customer, lol. I hate these products.

So the second I made an error and hit submit I tried to call, email, no response. After receiving the two products (tape and caulking), I called customer service and the person "Katey" was VERY rude. I could tell right away she did not care about my issue of ordering the tape instead of the caulking. I wanted to return, or maybe exchange for a second caulking since the amount is such a STINGY, small amount I may not be able to caulk much with 1 tube, but miss "Katey" was SO rude, I said forget the error. Forget there was NO RESPONSE to try to let the so-called "business" know and just go on and make a review to let anyone know this place only caters to collecting money, so make sure you don’t make a mistake of needing any customer service. ONE very rude customer service rep. Never again.

Flex Seal is a JOKE...they shouldn't even be allowed to use the word "seal" in the name! Had two cans of the clear and one black none of which did ANYTHING to seal a few small leaks that didn't amount to much to fix. Should have known it was a SCAM when I saw the fake commercial with cutting the boat in half! DO NOT BUY FLEX SEAL!

Used three cans of product on the roof leak and still it dries up, cracks, and leaks.

I've purchased all of the Flex Seal products. Silicone tape pint can of sealant. It's all garbage. The Silicone in the bathroom doesnt last long. The tape weather's like all duct tape products. The pint can doesn't seep into cracks...my roof and walls are ruined because I trusted the product and used as directed.

This company should be fined and ashamed for false advertising.
