UPDATE TO FLEX TAPE: kzfaq.info/get/bejne/p51ids2BrdaWeJs.html Tested on a pool liner!

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.

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

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

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

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!

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.

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.

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.

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.

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

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.

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!!

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

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.

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

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 👌

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.

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.

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

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!

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.

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!

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

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

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

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

From One Jeff to another Great job

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.

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

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 have not used Gorilla Tape, but have been disapointed in one of their products. I used Flex-Tape for my shower and other things and it has held up quite well. Not a permanent solution, but then again, I can't afford to remodel my bathroom. I think the fact that they sell twice as much at the same price, says a lot. But, if you are really looking for a lot of good solid quick fixes that you do not expect to hold, then the Gorilla is the go-to. Save money, fix things. Thanks for the video!

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.

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.

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 giving us your time with this challenge

Thanks for your hard work

This guy is the next spokesman for flex tape.

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

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

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

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!

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.

Thank you! I was wondering these exact questions.

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

Thanks. Definitely gonna buy flex tape for my project🤙

Great information on both taps

Now i know slapping on two patches of flex tape on both sides of a hole would do an even better job. Very interesting review by the way. Thanks man 🙏

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.

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.

Thank you! Informative and thorough. Appreciated. Subscribed.

Excellent review, the way you slap that tape to the bucket lol The gorilla tape is not equally getting as much pressure exerted to the tape as to the flex tape. The flex tape is the real deal.

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

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.

Thank you Jeff

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 :)

I was just at the store trying to decide between the two. Flex tape is the winner.

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.

Very good review. Thank you for sharing

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

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.

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.

We have used both and they both work well and when applied to a dry prepped surface there is not difference. Other than the "Flex Tape" is twice the price as the "Gorilla Tape" (Per foot)... We now use the Gorilla Tape since it works much better for sealing trailer roofs since it is more flexible and found the stiffness of the Flex Tape during the hot summer months starts to leak... Whereas the Gorilla Tape adhesive will seal better after it heats up..... And it's 1/2 the price of Flex tape...

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.

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 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!

I much prefer FLEX spray and tape for water leaks specifically. I had a leak in my pond where my water source came up into my upper retain basin. I used flex spray all underneath it and stopped the leak. Even after 17 degree temps it is still holding. Used the FLEX tape to cover a crack in water supply line. This stuff is amazing. I have also used FLEX caulk and construction adhesive. Awesome. However, If I have to bind or repair anything away from water, Gorilla is my go-to, especially on wood- Gorilla Glue is the king!! Both amazing product lines, but I go by what my application is going to be.

the difference is when the water pressure is being use to support the contact by the water being on the non sticky side, it helps the hold but the water pressure pushing the tape off the bucket it won't last as long

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.

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.

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.

Thanks man, I've got both tapes and a small hole in above ground pool. I appreciate the video!

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

Best Vid EVER!

Great Review i will be using Flex Tape for Outdoor Tarps and green house covers for now on and Gorilla tape for just wrapping things firmly but T-Rex Tape will be my overall EDC kind of tape or just laying around in the closet due to best value per roll.

Really useful test. Thanks

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.

Thank you Jeff.

Awesome Review

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.

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. :)

You are awesome jeff thanks for sharing that

Good video, I used Flex tape on my above ground pool and its held up for 3 years now. I put it on the inside. I use Flex tape for all my pool leaks and so far it works great.

Legend has it that Jeff still hearts comments to this day...

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.

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.

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.

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!!!

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 ?

I used Gorilla tape to repair my Morey Boogie board 8 years ago. It's gotten heavy use in the ocean, and the tape is still exactly where I put it.

Thanks. Helpful info

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

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

The Gorilla tape stretches for flexibility; it gives, but that makes it stronger because it isn't rigid

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!

Had a small hole in my kiddie pool that needed to be patched. Bought the Gorilla Tape since is was twice the length of the Flextape for the same price. I also found that the Gorilla Tape took some time to get it to stick to the pool liner. Put a patch on both the inside and the bottom of the pool liner. Will check this afternoon to see if the patch has sealed. The only problem I had was getting the roll to start unrolling. The edge of the roll had adhered to the black face and it took some doing and tearing of the tape to get it going. Was a little surprised at how well it had stuck to the black face since when I pulled off the clear liner, the tape did not seem that aggressively sticky. Thanks for this video, it really helped!

I used that gorilla tape to repair holes in my automatic pool cover. First time, it didnt work. Half the patch came off clean and allowed pool water to leak onto the cover, while other parts were stuck pretty good. I had cleaned the area with windex first. Second time around, I cleaned it with windex, then wiped it with acetone, applied patch, then hit it with the heat gun. Its been pretty much glued to the cover for about 3 months and has not leaked (2 patches). A friends dog (chocolate lab) came over, jumped on the pool cover the other day and ripped a new hole and just applied another patch. The cover is old and needs to be replaced, but I just want it to last through the winter. I just bought some flex tape and was wondering if they were the same. Thanks for tests.

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

Still in the beginning of the video, but already a +1 because you used 2 different colors for the ease of the video! now that's smart thinking! :D

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)
