FLEX TAPE vs. Gorilla Tape: which one is better? [9] 

UPDATE TO FLEX TAPE: ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-q72CjPHp2Hg.html Tested on a pool liner!

I bought a bucket without a hole it, it was cheaper than both tapes. Lol.

These two companies should make a product together. Called Flexing Gorilla🙉Lol.

Thanks for sharing and comparing, nice job on that! I was wondering if one had a stronger smell than the other? I'm planning to use it around venomous insects that are sensitive to scents. :)

I have used both Gorilla tape & Flex tape to repair my rv roof. The Flex tape was ok, but needed replacing in less than 6 months. The Gorilla tape was still good after about one year. The real test is endurance. Enjoyed the video.

Idk why ppl would thumb down this... Haters gona hate bro. Good demonstration thanksssss

Very helpful review. We have a couple of leaks in the seams of the gutter around our entryway roof overhang. Going to clean/prep and tape them up.

Great video man. This is my first time watching a video from your channel, and I think it is amazing. Keep up the good work man.

Flex tape can fix anything, To show you i sawed this relationship in half.

Walmart is carrying the Gorilla one as well, I saw it yesterday,. In fact, they both Gorrilla and Flex tape are on the same shelf

Really glad that you left the video on while you tried to peel the flex tape! I had the same problem. I do like the fact that you get twice as much with the gorilla tape.

found a leak in my shipping container building. With your help, I know now that I can try some tape, and expect that will be resolved until a better more permanent plan can be put in place! Thanks Jeff!!

Thanks dude, I have a pretty big drain pipe leak under my kitchen sink so this demo was helpful in showing that while one brand may be a bit better than the other both of them work. Providing my issue can even be fixed with adhesive tape, temporarily or not, something I am really hoping will be the case because otherwise I'll have to buy a new counter as its rotting underneath, sink and piping which we all know will lead to new cabinets and drawers etc. and I don't want to spend what little money I have left (emphasis on "little" thanks to covid causing me my job) redoing my kitchen.

Thanks for this video Jeff! I learned a lot and it helped me make a better decision on purchasing my underwater pool fix tape. Keep doing what you're doing 👌

I used Gorilla patch and seal for my Rv roof. I like it better than flex tape because it has more flex and stretches better plus you get twice as much for the same price. I do recommend if you're using it for a roof patch to make sure you clean the area well and honestly using a putty knife to push it down is helpful too but I feel like it's a better product all around.

The Gorilla Tape stretched but then returned to the original length after you set the weight down, which comports to your early on comment that the Gorilla Tape felt "rubbery". The Gorilla Tape would have won hands down if it had the same adhesion as the Flex Tape. The fact that you pulled the backing from the Gorilla Tape easier demonstrated why it didn't stick quickly. Good test and fair evaluation. Thanks for the comparison.

Jeff brilliant review. Very objectively done and it is very helpful. I have been using the Gorilla tape though but will keep my options open when i have to replenish. Again, very helpful video. Tq

Great stuff! Exactly what I needed to understand for a non-pressurized auto application.

Thank you! I was wondering these exact questions.

I am a strong believer in the Gorilla tape, and was quite sceptical about using the Flex tape, but after your demo, you made a believer out of me to try and use the Flex Tape in the future. I have used the Flex Spray to fix my Bird bath... And it worked PERFECT, since July 2020

I've been using flex seal for the past 3 years instead of sandbags during hurricane season. It's kept a room that otherwise floods dry for 3 years now. I'm buying more to get ready for Ian!

I used gorilla glue waterproof tape on intex pool liner , bottom of pool while full of water. The trick on the gorilla glue is to remove film and set in sun . It’s like tar the warmer it gets the stickier it gets . When cold doesn’t perform very well if at all on application. Hope this helps!

Used Gorilla tape on plexiglass porch windows with temperatures down to -40 and it welded itself to the plastic surface.

In Wisc we have property and have a trailer and behind trailer we have a large vinyl garage that we store mowers, ladders etc inside. One year a heavy tree branch fell on it and punctured the vinyl garage, and left a hole w a tear about 4x7 inches. Various patches would not stay, but about 2-3 years ago I bought some Flex tape and applied it from inside of vinyl garage and the hole was on the curved area of the vinyl garage. I applied a large strip of FlexTape w about 2-3” excess past the hole on each side, And I have to say I’m very happy with the results! Worked excellent for my purpose. Tried some on roof of our trailer though but it did not stay. Maybe flex paste would. I may try that next.

Awesome 😎 I’m gonna LOVE this channel. Brilliant!!!

I’ve used the Gorilla waterproof tape and it doesn’t stick well to wet surfaces. But dry clean surfaces it sticks like crazy. It’s rubbery and stretches some and hard as hell to remove. Very useful and quality tape.

Great review. I'm glad you dried off the outside of the bucket and continued the review. I have some Gorilla tape that I hope will seal a small crack in my flat roof.

I'm glad I landed on your channel. You so accurate and detailed. I'm surprised your not on TV doing commercials 😊🤣. But I subscribe to your channel. And cant wait for more to come. Thanks Jeff. I be waiting

Thanks for the video. Had to do a quick fix as hurricane dorian was passing by. Very helpful!!

Thanks for giving us your time with this challenge

Thank you for the demo. It answered a lot of questions.

Love this! You sure saved me some money ! Thank You!

I used Flex Tape last year. I had major difficulty trying to cut it because the glue from the tape stuck to my scissors and also to a knife I tried to use. It was also next to impossible to start peeling the backing off. I was using my fingernail to try to separate the backing. I finally got the backing off, and the tape is still holding over a year later on an inside project. But edges of the tape are starting to lift up on the outside project. I also tried the liquid on a metal shed roof, but it wouldn’t spread. I think the metal was just too hot. The temperature was in the nineties and the roof was in direct sunlight. So I didn’t finish the shed roof, but I’m going to try again, now that it’s cooler outside.

Thanks for this - really useful in my decision making. Am choosing Gorilla for my needs (dishwasher patch) and will let you know how it goes!!!

Used flex tape on hairline cracks on my foundation. Inside and out. Over a year ago and is still keeping basement dry. Outside crack was a rushing stream. Am sold on flexseal tape. Will always have some on hand.

The top of my van windshield leaked. So I used the Gorllla. They didn"t have the Flex tape at my Walmart. Better bargain anyway. And I like the black color. Sticks immediately, so make sure you got it where you want it.

Thank you! Informative and thorough. Appreciated. Subscribed.

Thanks Jeff...my pool floater needs repair..will try the one I can find in my area.

Hello Jeff, I have old tarpaulin which has some pinholes caused by the tarp containing gravel for a time . Need to seal these to make some ponds to raise duckweed and azolla for chicken feed. Water in the pond will be about 8 to max 10 "deep. What would you recommend, flex or gorilla tape? Would appreciate your comment

Reading the directions is important. They say to clean the area first, making sure there isn't any dirt or grease in target area. Then it says that strength of bond increases with time and some bonds may need 24 hours for maximum bond. Would be interesting to see how the bonds were after 24 hrs.

Actually there are A LOT of variables in trying to do testing like this. How big the hole is and how deep the water is make sure you difference and pressures and what not. So doing a test in a bucket isn't going to relate to a hole in the side of an above ground pool towards the bottom cuz there's crazy amount more pressure and weight pushing down on it. Good preliminary testing regardless so at least I have an idea of what I'm looking at now so thanks.

Great information on both taps

Hi Jeff, Thank you so much for this review. I am a person who loves DIY projects and was looking for a strong and waterproof tape. This video was extremely helpful in making my decision. I will definitely be using Flex tape for most projects however. I will also keep the Gorilla tape around as an alternative if needed. I do find it very interesting how the Gorilla tape was able to stretch. I was thinking that while stretched it may stick faster with out having to hold it until it sticks. Just curious. Thanks again.

i appreciate your reviews thank you so so much. ❤for looking out. especially for us single women who wouldnt not know.

Thanks for your hard work

Enjoyed your channel,so glad to see someone actually telling the truth

Thank you for this demonstration Jeff. I definitely feel flex tape is worth trying on the slice I accidentally made in our plastic pond liner while trying to trim silicone away from a drain that was sealed to a hole made in the bottom of it. Do you think that this tape could be shaped around the drain, to ensure a smoother surface, for a flat rubber plug to rest upon? I used a lot of silicone to secure the drain. I also tried to repair the slice I made, with additional silicone. Would the set silicone applications need to be completely removed, before taping with the flex tape, for a proper adhesion? Or could I work the flex tape over the silicone as it is, and still achieve the seal that I am hoping for?

Thanks. Definitely gonna buy flex tape for my project🤙

Need to remove the Flex Tape? ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-GFg_V5Z2b-U.html

Jhang Jeff. I was just about and buying both. Do my own test. Glad for you doing the test.

Hey Jeff I've used both products for pond repairs and I've found that gorilla tape is better and both products recommend that you use them on a clean dry surface to ensure the best results.

in the footage you can see the gorilla tape bulging around the hole.

From One Jeff to another Great job

Thanks for this study. I was wondering which one would perform better. Im going with flex

I've seen around on youtube Flex Tape works well on fixing air mattresses, so whatever works best for patching a hole on an air mattress. Seems like typical tape doesn't really do so well. I haven't tried duct tape yet, but I've heard it doesn't do so well either to cover a hole on an air mattress.

I have used the flex spray and had good results. I did not know about the tape. Glad you reviewed it.

Thanks. Helpful info

I used the white Flex Tape on an outside seam on one of my gutters. There was some leaking. The tape began to disintegrate in less than a year until it started to peel off the gutter in pieces.

I used the flex tape to hold down tarps for a hurricane in Florida! This stuff is amazing! Complete hold during hurricane Ian! I will never be with out it!

thanks for this! 'gotta fix a porta bote - i think the flex tape will do the job kd

I use Flex Tape as a keel guard on my Kayak! My kayak was showing some wear from rocks, gravel and concrete boat ramps. It's taking a beating but serving the purpose well!

Hey! I am trying to find some waterproof tape to fix my above ground pool I am so glad I ran into your channel. I was on the fence about which one of these to get. I think I've decided on the flex tape even though I am going to have to use more than one roll. I actually didn't like the way the gorilla tape performed. The liner is coming detached from the rim of the pool and the gap is quite wide long and wide. This has been going on for a while so I figured I had better do something. I don't want to drain the pool at this point and have someone fix it. Thank you for your review.

My Gorilla tape doesn't have the plastic liner, but directions say to peel off the liner before application.

Used the clear flex tape to repair the rips and holes in my boat cover. So far so good. I will say this, 5 feet of flex tape goes very fast! an extra 5 feet of Gorilla tape for the same price is a huge advantage especially if you need a lot.

Thanks buddy I will be heading out looking for some flex seal tape tommorrow

Thanks Jeff, I wanted to know which to use for a paddling pool repair. Many thanks. Jane, England

Used some flex tape to repair a roof leak in my sunroom that others claimed to have fixed. Cleaned and made sure shingles were brushed to remove loose stuff applied and still holding 2 1/2 years later. If applied correctly it works great and will save ya some cash.

Cutting the flex tape is so much of a pain,but it sealed my tiny sub basement window up really good. The barrel by the window would fill with water every rain and the pressure would push the seal open,and the water would pour into my basement. I got sick of fixing the window zsi I flex tapped it about 1 year ago,and it's still holding strong

Thank you so much! This video was really helpful because you show how the product actually works. Wish I could take back 2 minutes after watching tylertube.

very usefull information i will be going for flex tape thankyou

I have a flat roof that has Gaco silicone coating on it. It developed a few cracks and was leaking. After watching your video I went out and purchased one roll of each. It was barely sprinkling when I attempted to make the patch. However I made sure that I wipe the area down with dry rags and also sprayed it with alcohol to facilitate the water evaporating. It certainly wasn’t completely dry but there were no drops of water. Sadly neither products worked at all. In fact when I went to rub them down they kept moving because they did not adhere. I will try it again on a sunny warm day but as far as it’s sticking to moisture that did not happen in my case. It may be because it doesn’t stick to silicone.

Great review. I have used flex tape. The only down side to flex tape is it should be 10 feet instead of 5 feet. It’s a great product.

Hi Jeff, Thanks for the comprehensive review, it's always better to see real-world tests than ones done under lab conditions - as I'm sure the manufacturers base their advertising on. I am looking for a tape to run along the plastic strip that sits beneath my car's windscreen (to get the rain water to run over the plastic instead of finding its way underneath and getting into the pollen filter), I don't want to use silicone sealant as the plastic part needs to be removed to swap out the filter. Any recommendations of the best tape to use (either one of these or a different one?) Ideally it should be clear, but black would also work. As you may have guessed I am in the UK by the way, so am hoping Flex Tape, etc is sold over here.

I'm considering using one of these to repair rips in my tarp..tarp for flatbedding...I wonder which might be stickier and more durable

Thank you Jeff

Omg you are a life saver thank you Jeff. My kid popped a hole in my air mattress while camping and I didnt know what to do. So I came across this video and boom. Easy fix.

I would think the fact the the Gorilla tape stretched (flexed) more than the Flex tape would be beneficial and not a con unless you are using it to lift barbells.

You are awesome jeff thanks for sharing that

Really useful test. Thanks

I would love to see that flexseal can be used for coating roofs.

Thanks for the review. Little dudes pool just got a hole and now I can fix it and not shell out more money for a whole new toddler pool this season!

So I have used flex tape on my pool liner which has a hole size of quarter. The tape adhered well but I did drain pool first, however, after refilling it with water there was water leaking again by next morning. Ive used gorilla tape in the rain for a tent rip and it failed too so I don't know about either of these products holding up after applied over time. ☹️

Jeff if used the flex tape in Black I bought from Amazon on several occasions all under water situations, my hot tub etc. I LOVE IT, works great definitely recommend it.

Yes, Jeff. I've Used both. Gorilla tape cus an ultra sticky duct tape. Nothing more. It would not hold on washing machine drain hose. Flex tape not only works on that, but pressurized hoses and PVC PIPE!

Just so I needed to know! I feel like the flex tape is much better the Gorilla Tape didn't stick where I had hooked a PVC faucet into a hose and then turned on the water and it popped out but using the flex tape it sealed and it didn't pop out. Thanks for your demonstration

If you do a dry application then fill it with water, do the tapes perform better? Im trying to fix a cracked plastic water container, im.debating if i should fix it with tape or just spend the money on a new container (the container costs $150 or i wouldnt consider this)

Hi, I have an inflatable pvc boat for the river and lake. I want to tape the underneath water side down of the boat for a double skin layer protection so that it won't puncture so easily? in your opinion which tape is the strongest 💪 as a puncture preventive measure and sticks the best? Thanks.

Tried the white Flex Tape on my cleaned surface inground vinyl pool liner to cover a small under water rip, pealed off after a couple of months. Also tried to patch an above waterline rip exceeding 6 inches beyond the rip. The Flex Tape didn't stop the rip and peeled off after a month.

wow this was great video! honestly water will always find a way . i used gorilla glue and it was crap just FYI

Hi Jeff, i was wondering if Flex Tape or flex glue would be good to seal old cracks in my loungeroom which is lined with plaster board that has cracked because my house stumps move throughout the year from weather variations? Does it have any "give" for seasonal movement? Also i have a windowseal that is made up of two 5cm horizontal running wood but noticed theres a small gap between them that goes all along the outside windowseal & im hard to know if rain may be getting into the old outside wood walls underneath the sill as the whole house has been covered by some outdoor weather/ insulating horizontal covering that many of the old houses have around these parts. Problem with the insulating plastic(?) is that i can't see the condition of the timber underneath. Any suggestions re the inside gyprock wall cracks & whether i should be using the tape or some kind of bog like sikaflex or "no more gaps" Thankyou for any advice :)

Great video. Thank you. Can you please make a video on comparing Flex seal spray/ Flex spot and comparable products to fix a ceiling leak?

Which one would you use to patch up a large vinyl pool floating island thing? Should I really just use a proper pool vinyl patch, or would the gorilla tape work ?

Used flex seal spray while the hurricane was pushing my window in. It sealed and dried while the water was spraying in sideways into the house. Made a mess but again sealed and stopped the water during Irma. Not bad in my opinion. Had ordered new windows but freaking hurricane hit before they were in.

Excellent information. Thank you.

Very good review. Thank you for sharing

The Gorilla tape applied on the outside is showing signs of the water creating channels between the tape and the bucket and its approaching the edge of the tape. Water is not creating channels on the bucket with the Flex tape. Flex tapes appears to be better.

This guy is the next spokesman for flex tape.

Have you done a review on a dry application? Looking to repair a tarp. Thank you for the video.

Thank you!!
