Strong adhesive tape
[This review was collected as part of a promotion.] I used the Flex Tape in my bathroom to reinforce the seal around my bathtub. The tape that was there was peeling off and needed to be repaired. The tape works excellent, the bonding surface should be dry prior to applying the tape. I used the extra wide tape which was slightly too big so I trimmed to the size I needed. There have been no leaks so far and the seal is tight and waterproof. I am definitely picking up some more for some other repairs around the house. Flex tape is a super strong adhesive tape that has a rubberized backing, works underwater and instantly stops leaks. I highly recommend flex tape for sealing out water, air and moisture leaks.

Good stuff
[This review was collected as part of a promotion.] I’m happy I got this stuff! I’ve used it before and it works well to deal things up. Most recently I used it to seal a small hole in my air conditioning duct work. It has done a good job and has limited the air leak. I’ve used this before and will get more in the future.

Heavy duty seal
[This review was collected as part of a promotion.] I am in absolute shock in how well this tape works. I was skeptical at first to try this product out on our cracked window in the middle of winter with rain and snow outside with freezing temperatures, but my wife insisted we try it anyways. I thought for sure we were going to have to replace our window, but much to my amazement, this tape has sealed and held up despite these extreme weather conditions. It truly does have a super strong adhesive backing and holds up well. I love that it is 8 inches wide which allowed us plenty of room to cover the entire crack on our window. It definitely is waterproof and has not allowed any moisture to come through on the tape or around our window where the tape is placed. It has not peeled up around the edges and has bonded strongly to the glass surface as well as the wood frame of the window. I would definitely recommend this to others who are looking for a strong adhesive, waterproof, get the job done, without the worry, tape.

This Stuff is AMAZING!!
[This review was collected as part of a promotion.] I figured I would get a roll of Flex Seal tape just to see if all the hype was true. As an engineer, I wanted to see if it would really work. Having played with duct tape for years to do repair and knowing its limitations, was this tape really better? Bottom line, YES it is!! I had a chance to use it on a repair for my water hose that was going bad. I opened the package and unrolled a piece of tape, the first thing I noticed was the tape itself was very thick and made of a rubberized material, like a pool liner. The material is very pliable and will mold itself around any curved or odd shape. To cut it, you need a good pair of scissors, there is no tearing this tape. The second thing I noticed, is the glue used on the tape is unbelievable. Once taped to something, especially to itself, its virtually impossible to take off with out cutting it off. The first time I wrapped it around the hose, it was a little uneven, I needed to cut it off to do it a second time. Once I reapplied the tape the hose worked like new. There are a few tools that every house needs, hammer, screw driver, etc… Everyone needs to add roll of Flex Seal tape. The number of applications for this tape is endless, the quick temporary patching of holes in walls, to stopping leaks in pipe or hoses, to things I can’t think of yet but will have Flex Tape for it just in case. I would highly recommend have some on hand just in case and give it as a gift, they may look at you strange, but they will definitely thank you the first time they need it.

Great stuff
[This review was collected as part of a promotion.] I noticed my floor damaged from water and being scratched from a potted plant. I did not want to repot the plant, so I used Flex Tape on the bottom. Not only did it stop, the little leak but, it protected the floor when I slide the plant. Flex Tape is easy to use and cut. I like the 8" x 5 " size, it makes a project like that easy. I am happy to have this in the house, you never know when you will have a leak. It is good stuff and I highly recommend it.

Works as advertised!!
[This review was collected as part of a promotion.] Beware this tape is super sticky. Don’t try dealing with it in the wind as I tried using a cut long strip to patch a tear in my swing awning and the wind folded the piece onto itself to where it was permanently stuck. I used a different piece and it worked as advertised to fix my torn awning. I will see if it holds through the weather but so far I’m impressed. I look forward to using this tape in other situations around my house.

Pretty sticky
[This review was collected as part of a promotion.] Well, I tried this with our pale with a hole and it is pretty sticky. Tried putting water on it and no leaks! This could help those broken stuffs at home to be fixed plus it is waterproof! It is mess free unlike those that creams that needs to be mixed thoroughly but with this, it is easy breezy. But I hope they also comes in small sizes because it is easy to roll it in a small things that needs to be repaired.

Decent Product But Difficult to Use
[This review was collected as part of a promotion.] I was excited about Flex Tape and being able to use it to cover up a hole in the siding of my house. In fact, it seems to be working well on that patched hole. Here’s what I liked about Flex Tape. It’s wide. It’s 8” so it will work well in patching larger holes. It works in hot or cold temps. It even says it works underwater! It’s flexible so it works on odd shaped surfaces. Speaking of surfaces, it says it works on almost any surface, even brick. I like that the Flex Tape is available in Clear, White and Black making it blend with multiple surfaces. While I like some of what Flex Tape offers, I had a HUGE problem with how difficult I felt the tape was to work with. The instructions literally say “Just cut, Peel, Stick & Seal” It sounds so easy doesn’t it? It was a pain in the behind. With it being super sticky cutting is almost impossible. The first try it was so jagged and crooked and sticking to itself I had to toss the piece out once I finally got it cut. For the second attempt, I had to get my wife to help me pull and cut the tape so I could hold the other end tightly with hopes of an easier cut. She cut the piece and it went a little smoother as she slid scissors across it like a razor blade instead of using a cutting motion, which is suggested on the instructions. It wasn’t perfect but did work better. Once it was cut, it folded over and stuck to itself before I could get it into place leaving it useless. Finally, on the third attempt I was able to get a piece of tape I could use. While doing all of this cutting, the plastic backing, which should help you separated so easily from the Flex Tape, I found it to only hurt my efforts. In the end I was able to cover the hole in the siding as I had hoped. It stuck well to the siding and covered the hole completely. The Flex Tape packing says the bond only strengthens with time so I expect this to hold until I can get the piece of siding replaced. I do recommend this product but I do so with caution. A product like this should be easy to use and not frustrating. After all the trouble in using this product I would look at other options as well before choosing this again to make sure I was getting a product that is easy to use as well as one that works well.
