Flex Seal Reviews

Do not buy this junk. I must now paint my house because the Clear Flex seal turned YELLOW. Purchased 4 cans, turned yellow within 6 months. Stupid company wants proof of purchase from six months ago.

I recommended to my daughter to buy Flex Seal glue for a project she had. Well, this product gets a double FF. I thought maybe she had used it wrong so I took it home and used it on the kitchen table, again double FF. On the commercial, it sticks immediately, in the directions it's 24 to 48 hours. This is false advertisement. Also, it was extremely hard to release the glue from the tube. She said she kept her receipt. They should stop selling this product before a class action is started.

This product does not work. I wish I could sue them for false advertisement. I will not be purchasing anything from these liars. I hope no one else does as well. So please keep bonding flower pots. It does not seal leaky roofs, so stop claiming to seal leaky roofs...I have a metal roof and it's still leaking despite using the tape and metal jar.

Worst product ever, all of it. I used it all to repair a leak on my trailer on the top on the tear the nail hose, I even doubled it, I bought a gallon of it, I bought it in a spray can, I bought the tape, it’s all hard to work with. It dries up and then cracks open. Nothing of this product has worked. I can’t believe that people get by selling stuff to people who have no idea that it doesn’t work. I think I read one, maybe two good reviews and know what it must’ve been a simple job, maybe a bad job, they said it was a good product, it’s not.

This does not work. I tried the tape on a small water leak and it did not work. I tried to seal a roof, it did not work. I tried to run a bead on my boat to seal it but it dried up and cracked all three products. No good.

This is one amazing product. I have used it to seal my basement wall, and used it everywhere on my travel trailer as I was restoring it.

I purchased a used 2000 model Coachman 25-foot travel trailer. The wheel well wasn't sealed which allowed water to enter the interior and rot out the floor, which was the reason it was sold as a "fixer-upper". I sealed the wheel well with Flex Seal tape and coated the remaining well with the spray-on Flex Seal. The floors were replaced and the subflooring coated with Flex Seal. Then the floor was covered with laminate flooring. The roof needed repair and I used Flex Seal tape to seal the edges and all the flanges of any vents. Then coated the roof liberally with Flex Seal liquid white. Lastly, the trailer's awning appeared to need replacing. I found only the first 8 inches of the awning had sun rot. So I coated the entire length with 8-inch Flex Seal tape. Then sealed all edges with white liquid Flex Seal.

My wife and I used the travel trailer all summer. Not one issue with any leaks. I strongly recommend Flex Seal to anyone who has a need to eliminate water from entering their home, or camper. Excellent product. You must follow the manufacturer's recommendations and to be sure to clean surfaces before applying.

Bought this as someone recommended it to keep my galvanized tub from rusting. Painted it, waited, filled. Start peeling a few days later. Drained tub, mind you we're talking 200 gallons, left another thicker coat of paint, waited, filled. I just drained it again for the winter and it's peeling everywhere and got bubbles. Went thru two 1-gallon buckets on a 6ft tub. Waste of time and money.

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.
