Rated 5 out of 5 by from Great Stuff [This review was collected as part of a promotion.] Used the roll on a school flat roof that had a very serious leak. We dried it as best as we could then applied the flex tape. The next rain, problem was gone. Roof is in need of replacement, but current funds are not available. Flex tape worked great

Rated 4 out of 5 by from Great Leak Stopper! [This review was collected as part of a promotion.] The very first thing I used this tape on made a believer out of me! We have a five gallon water dispenser in our kitchen. Recently we put a new bottle on and soon after we noticed some water on the floor. It took awhile but we finally discovered a hairline crack in one of the seams of the plastic bottle. I remembered I had this Flex tape and decided to give it a try. My husband was pretty skeptical but to our surprise it actually worked! Very impressed!

Rated 4 out of 5 by from Handy [This review was collected as part of a promotion.] I recently tried out the white Flex Tape on my watering can and was pretty impressed. I’ve been in the market for a new one so I was pretty annoyed when it developed a small crack on the bottom side. I cut off a reasonable size of tape and slapped it on. It does protrude but it got the job done so I could get my job done of watering the plants.

Rated 4 out of 5 by from Flex tape is great! [This review was collected as part of a promotion.] This stuff works pretty decent. I only used this for something I would try to duct tape. This doesn't really work on water resistant. It says it will work underwater, it does not. Even if the surface is wet it will not stick.

Rated 3 out of 5 by from great for short term fix [This review was collected as part of a promotion.] So, I was really open-minded when testing this. We used it on a couple household issues. It seemed to work well on some items but not others. Ultimately, our conclusion is that this is a great short-term solution but possibly not the bet longterm fix.

Rated 5 out of 5 by from Great product [This review was collected as part of a promotion.] Black flex tape is super handy to have in case of a cracked pipe at home in the winter. This new giant size allows for more applications. The 4 inch roll is still great but 12" wide sheet of flex tape is awesome. Adhears well. Easy to trim to size. Highly recommend

Rated 5 out of 5 by from Strong tape [This review was collected as part of a promotion.] Fist time buyer of Flex Tape, I had a leak and needed a temporay fix before plumber could get out here and replace pipe. This did a fantastic job stopping the leak on a PVC pipe for my sprinkler system. I would highly reccomend this product.

Rated 5 out of 5 by from Excellent and highly recommended [This review was collected as part of a promotion.] This tape is amazing! It definitely holds up so well outdoors. I love the fact that even in sunlight and rain it’s still stuck in place, I had to use it to stick the fly screen on around my window. I would definitely purchase and recommend to everyone I know.

Rated 4 out of 5 by from Super Strong Bond [This review was collected as part of a promotion.] I was so excited to give this 4'×5' White Flex Seal tape a try and I can honestly say that I wasn't let down. This tape is awesome! It has a lightweight, rubber feel to it and securely bonded to a variety of items, each consisting of different materials, textures and weights. I am an avid crafter and this will definitely be one of my new, favorite, always on-hand, go-to adhesives

Rated 5 out of 5 by from It does exactly what it says… [This review was collected as part of a promotion.] I heard that Flex Tape can seal anything at any time. I had a leak in the plastic roof on my sideXside UTV that I wasn’t sure how to fix. Water would just drip through the roof and onto my head which is more than annoying. I decide to put the Flex Tape statement that it can repair “virtually everything” to the test. I got the jumbo 8” wide roll and headed out to may garage. I cleaned the area on the roof to remove the dirt and grim and give the flex tape the best chance to seal the leak. I was amazed at the adhesive quality of the tape. I cut it to fit approximately 1 inch larger than I needed and applied it on the roof. It took all of about 10 mins from start to finish. Now to test that it did what I needed it to do. I ran some water over the tape and waited for the leaking to begin. Nothing. Dry as a bone. This stuff is fantastic!

Rated 5 out of 5 by from sticks! [This review was collected as part of a promotion.] This really works. I used it inside of my brick mailbox that had a few holes rusted in and was getting my mail wet. It does the trick, but bring your patience and an extra set of hands because I've never encountered tape this sticky lol. overall satisfied

Rated 5 out of 5 by from Works great [This review was collected as part of a promotion.] My husband loves this stuff. It comes in handy more than you'd think. It stays in place, bonds well, and does it's job. My teenage son stole the rest of the roll to finish the boat he was making. My husband was annoyed, but it turned out really well and was actually quite impressive. We will be buying more.

Rated 5 out of 5 by from Tape that gets the job done [This review was collected as part of a promotion.] This tape definitely gets the job done. It’s durable and holds together excellent. I used it to tape my moving boxes together and there were no issues at all. No hassle with getting pieces off which can be a pain when you’re trying to tape something in a hurry.

Rated 5 out of 5 by from great product [This review was collected as part of a promotion.] I run a couple race cars and I got this to fix the body when it gets tore up but need to fix quick to keep racing. Holds strong and keeps stuff in place. The glue doesn’t leave tk big of a mess when you need to take the product off when done using it. I would recommend this for a lot of fixes that duct tape is just alittle weak for. I will be buying again for sure. Came in the mail in time and nicely packaged.

Rated 5 out of 5 by from Works great [This review was collected as part of a promotion.] I bought this a month ago and it really works great for a water leakage. I used it on our shower head as jt has a leakage and it works well. At first i was hesitant to use it but when i applied it it amazes me as it works really well. Easy to use!

Rated 5 out of 5 by from Great!!!!!!!!!! [This review was collected as part of a promotion.] I got this product and I loved it so much! It was great and it actually works. I have already recommended it to family and friends and literally everyone! Lol This product works great with pretty much all materials.

Rated 4 out of 5 by from Got "just in case," finally used it! [This review was collected as part of a promotion.] I got a roll of Flex Tape just in case I ever needed it—I knew about its reputation to seal just about anything. I finally had an opportunity to use it when my winter boot split open at the toe. I cut a small section of Flex Tape and sealed it over and it held it together and kept out the snow and water! It doesn't seem to be a permanent solution—it's very sticky and tacky and seals anything instantly, but it does come unseated after a few days or with force applied. Recommend using a larger piece than you need, making sure the sides are seated on material that doesn't move, and to seal with a more permanent fix when you can. However, I'm glad I got it and it's good to have around for emergencies.

Rated 5 out of 5 by from Great tape! [This review was collected as part of a promotion.] The tape is very sticky! When you are taking off the paper backing make sure you get all of it, otherwise the seal won't be good. Be careful that you are laying it where you need it because its very hard to get it off. This tape really works. I would recommend for any project.

Rated 3 out of 5 by from Decent Product [This review was collected as part of a promotion.] This review is based on limited usage as I have not needed to use the product that often so far. With that said, it seems to be doing a good job so far. It does keep liquids out of whatever you seal up, at least for the time frame I've been using it for. I'll be curious to see how long it last.

Rated 4 out of 5 by from Does what it says [This review was collected as part of a promotion.] We’ve used this product a couple times to solve minor water issues. We inherited a rain barrel from the previous owners of our house. There were a couple leaky spots near the connectors which meant it didn’t hold water correctly & made a giant mud puddle. We put the tape over those spots and it seems to be holding up well over the last several months.

Rated 4 out of 5 by from Messy but efficient [This review was collected as part of a promotion.] From the few repairs I have used this tape for, I am satisfied with the results. So far I have used it to fix a hole in the garden hose and a pipe under the sink that was slowly leaking. Both repairs did require a second reapplication of the tape to ensure a strong hold. My only issue with the tape is the adhesive is quite gooey and can get quite sticky and messy along the tape edges. Overall I would recommend the product as the repairs are still holding and I have not had to remove or apply additional tape to my initial two applications of tape.

Rated 5 out of 5 by from AMAZING! [This review was collected as part of a promotion.] This tape is AMAZING! Both my husband and I have used this dozens of times so far! My husband has taken this camping too - as a handy option to repair items while in the woods! Super easy to use and very strong!

Rated 5 out of 5 by from WOW! [This review was collected as part of a promotion.] What a great product! After seeing these commercials on TV I have always wanted to give this a try . This tape really works and it works wonderfully. I recently had a rip in my pool liner and gave the tape a try not only did it stick to the wet surface stopped the leak and it is still holding fast! My sink faucet always had a slow leak when running water now that is fixed as well and still holding strong. This is a great product and look forward to try some of the other products offered in this line of products

Rated 5 out of 5 by from Great product! [This review was collected as part of a promotion.] You've all seen the commercial using the tape to repair everything from a pipe to a boat. Let me tell you it works. I used this flex tape to repair a tear in a pool liner. Some of it was applied underwater, and some above, but it worked like a charm.

Rated 5 out of 5 by from This stuff is magic! [This review was collected as part of a promotion.] This product works better then I thought it could. I did not think it would stick or stay stuck as well as it does. The only problem I encountered was trying to use it one day on a very cold day. You should avoid putting the tape on in very cold or very hot weather. Other then that the product preforms well. And, I especially like the clear tape. I made a repair and my wife could not even see the tape. I am her hero!

Rated 5 out of 5 by from Works great! [This review was collected as part of a promotion.] I got this in hopes of repairing the leaking pipe under my kitchen sink myself without having to call an expensive repair man. It worked better than expected. I just shut off the main water, dried the pipe and applied the tape. I let it sit for an hour or 2 before I put the water back on just for good measure. I put the water back on and no more leak. It's been running strong for over a month and I'm so happy to not have to replace the pipe as it would have cost a bundle. I highly recommend this!

Rated 5 out of 5 by from Lifesaver [This review was collected as part of a promotion.] I had received a roll of Flex Tape in the mail a few weeks ago, but threw it in my junk drawer and kind of had forgotten about it. Last week, we had a really rough snow storm that melted the following day and we discovered we had a slit in our drain gutter on the side of the house. I immediately thought of Flex Tape and ran inside to get it. I pulled some off the roll and followed the instructions on placement. Within minutes, the leak stopped and all was well. Not only did this save me a trip to the hardware store, but now made me walk around the house trying to fix anything and everything with this bad boy miracle tape! Highly recommended, even if you just keep it on hand for a rainy day!

Rated 5 out of 5 by from Incredibly sticky! [This review was collected as part of a promotion.] This stuff works like the commercial! We tested it by cutting a whole in the bottom of a cup and we sealed the leak from the inside while the cup had water in it. Try not to get too much stuck on your finger, it’s so sticky. I wouldn’t count on ever getting it off. I love the idea of have a roll of this around for plumbing emergencies. Total piece of mind.
