Awesome, THX! Being as this product hardened when exposed to air. Question: The gallon you used once the lid is cracked and exposed to air how long will the product inside last after resealed? Does the opened and resealed product harden in the can quickly?
We been using the clear FlexSeal spray for an unfound roof leak also for two years. But we recoat the area every 6 months b\c we don't know if the heat from the sun breaks seal down or not.
Ok you gave it a 10 out o 10 for the stuff you tested But if I used it on the bottom of a boat how would it stand up to it getting scraped by the shoreline over repeated time
Really, how well does it adhere to surfaces? You know, how some products like Caulk peel off like if it was a smooth surface, like if it was a casting medium for a mold.
Drill a hole in a wine bottle, Flex Seal the hole, fill it 3/4 of the way with Diet Soda, glue a Mentos to the bottom of a cork. Push the cork back into the bottle. Turn the bottle upside down. See if the cork or the hole blows first.....
One side of the can - "Non Flammable Non Toxic Non Hazardous" Other side of the can - "CAUTION: COMBUSTIBLE LIQUID HARMFUL IF SWALLOWED" So which one is it Flex Seal?!
so i think what it means is that it technically isn’t chemically hazardous but having liquid rubber solidifying in your stomach isn’t necessarily safe. as for the flammability contradiction, no fuckin clue
Thanks for the honest review. It seems too good to be true. I'm trying to apply the Flex Seal liquid to fix a recurring leaking from the bathroom from the second floor to the first floor. Nothing has worked. I'm trying to seal the exterior sides of the bathtub and base and the toilet base and corners of the bathroom where water could leak. I've tried reapplying grout and then caulking it, but it didn't work. Would Flex Seal liquid work? How long should I wait before applying the second coat?
You should paint it on a pieces of different materials (wood, shingle roof, sheet metal, glass) and expose those pieces to the elements for a year and see what happens after a year of abuse!
Great video, thank you. I'm making an outdoor wreath out of cardboard and paper towel rolls. I want to use flex seal to waterproof it and I wanted to know if after it is completely dry if it can be spray painted and if the paint will stay nicely or peel off? I would use a krylon paint I think?
Could this be used for exterior retaining walls that have slight cracked ? Will it stick on the wall and can it be painted after it has cured for 30 days? Thanks and great video!
Had a bad vaccum leak on a plastic intake on an automobile throwing engine codes. Bad location. Used the flex seal spray and my headaches were over. I wish they would attach a straw or tubing to the end of the can to pinpoint spray. I know it would have to be made out of material that wouldnt clog but it would make applying spray that much better for hard to spray places
Just as Flex Seal did with their aerosol product I imagine that they will offer a greater color selection after the product is on the market for a longer period of time. It's to see if it will be a seller
Do you think this would work good on the bottom of a metal kitchen chair.. I have metal kitchen chairs the plastic on the bottom has worn off and now it's metal on ceramic causing rust on my floor I've been looking for something that will go on the bottom of my black chair legs that will last when people sit on it and stop the rusting I figured I would dip the chair right in the flex liquid just enough to cover the bottom and then let it dry.. What do you
I enjoyed your demonstration for flexseal. However this product does and absolutely will break down over a period of just a few weeks to a few months depending on the application. It breaks down in direct and indirect sunlight. I have used the white, black and clear, and they all break down over a few months in outdoor conditions.
it makes me sad that you dont get more views. I love your reviews like i have said before. I appreciate that hard effort it takes to put out these videos. always looking forward to the next one. thanks JD
Great video: you helped me. I just bought the smallest size, planning to coat a 2' x 4' sheet of plywood to use as a table top in my wood shop. I need a waterproof surface for my wet sharpening stones and wet grinder. After seeing your review I'm not sure I want to use it: you said particles cling to it, and this makes sense because of how rubbery it is. But in my wood shop there is always dust here and there, even though I clean up at the end of every session. I suspect my Flex Seal table top will be forever pitted with little dust particles that I'll never be able to get out. Can you answer this question for me: once the Flex Seal cures, do you think the particles will come off with a wet sponge, or do they stick around more than that? Thanks again. You have a unique style, but it's clear you've thought carefully about your content. Nice work.
If you went with the clear Flex Seal instead of the black then the little dusty bits wouldn't show up nearly as much as they would against a dark surface :-)
I have a pipe that is leaking. I tried to use water resistant tape to stop the leak but it didn’t work. Do you think this will do the job successfully?
This was before Flex Tape (I think). I used Flex Tape to fix the passenger's side rear view mirror on my car. after being in the sun, it lost it's grip and started to move. So basically all it did was leave a sticky mess on the mirror.
Can l put flex seal on my desk floor instead install new vinyl sheet desk floor , that was vinyl too old and worn out some where ., is it working for whole desk ? Anyone comment about that ? Thanks Hien
Can you paint over the top of it? I want to use it on the siding where I have cracks on my mobile home. There is large cracks forming where the pieces sheets of wood like material come together. (like T 1-11 but not) meet. I have to do something about them because this winter it will leak through it to the inner part of the house. Do you have any suggestions. Thanks.
I have pinholes in a canoe and thinking of using this, but my main worry is abrasion. If I fill the holes and it gets dragged on ground or bottoms out in shallows will the flex seal hold or not. Have yet to see anything about this.
Chuck Marianik ive got a jon boat I'm about to flex seal. instead of painting the outside I'm painting the inside. if it is as strong as it is advertised to be it should work either way.
How long you been working for flex Corp? Others tried this and it failed miserably. The company dupes people with the trickery commercials. These companies need to be held to the standard of what they advertise and show in commercials.
When paint or coat something, and you DON'T want lint from the air to settle on it...take a cardboard box and spray the box with water...then let it sit and drain so no water is dripping from the box...set the box over what you want to dry without lint or fuzz from the floating air....perfect! The water is to keep dust down in the box is all....Boom~!
I have a 500 gallon plastic (it is roto molded plastic - whatever that is) cistern that is full of water. There is a 2" threaded outlet at the bottom of the tank with a plastic pipe screwed into those threads and a plastic on/off valve screwed onto the pipe. The pipe, at the tank, has a small leak. I put silicone on that leak many years ago, but tonight I dislodged the silicone and it is dripping... Will this product Flex Seal work for my situation? I would like to remove the silicone and spray this stuff around the pipe coming out of the tank. Will this product work if my pipe/tank is a little wet?
i live in az where the heat is extreme and the wind can be strong , i used flex seal to hold brackets on my concrete wall , 2 yrs later the brackets and the tarp are still up.. , i also had a water leak from my hot water heater not once but twice , having to replace walls sucks so this time i sealed the walls with flex seal liquid , not taking any chances .. only question i have now is how do i remove it from the walls to repaint before i seal it again?
Have you oir do you know if anyone has used Flex Seal to seal minor leaks in low pressure tires such as those used on ATVs and lawn mowers? I'm not a fan of using slime, but this rubberized product seems to be a good match for rubber tires.
Hello Nitro is this available in clear liquid or spray , i need to use it to spray on bathroom tiles which are a little leaking , i think it should be a temporary good product to seal any leaks . pls advise . thanks
Great review..However I have heard that flex turns to power after a few month exposed to the weather..Any chance you could to another review after leaving it exposed to sun/rain for 6 months?
Colby Sanders I did the roof of my small RV a year ago and it sits outside uncovered and it is still as good as it was when I put it on. The secret is to clean the roof well. I also washed it several times. I would recommend it anytime. Half the price of the stuff you get at Camping World.
How does everyone else get it to look shiny? When I used it on a piece of a ferret cage I broke, it looked like matte black paint and had a lot of pores.

i used flex seal to get rid of all the leaks in my metal shed. AWSOME PRODUCT
Dude are you mario in real life?
@vsonic86 I was thinking the same thing lol
vsonic86 naw I say Cleveland
LOl!!!!!!!
vsonic86 luigi
vsonic86
naw the guy is black
maria is a white Italian person made by Japanese people man get your facts shit mierda correct vato lmao
If you buy white and buy different color dyes you can make your own flex seal .
Scott Campbell awesome Idea
I had a roof leak used flex seal spray, worked great repair done 5 yrs ago will buy again
Angel A.
I’m pretty sure it hasn’t been out for that long, but yeah that stuff is good for sealing leaks and cracks.
@Angel, I used it on my roof and gutters and did not work at all! Quit lying!
We been using the clear FlexSeal spray for an unfound roof leak also for two years. But we recoat the area every 6 months b\c we don't know if the heat from the sun breaks seal down or not.
@@dianneanderson731 , Spray it on your gutters when you get a leak on your gutters! I GUARANTEE IT WON'T WORK!
@@loribell9741 stfu
This might be a stupid question, but can I use flex seal (the spray can) to cover up a medium hole in a glass door?
Ok you gave it a 10 out o 10 for the stuff you tested
But if I used it on the bottom of a boat how would it stand up to it getting scraped by the shoreline over repeated time
Can this work on metal pipes to keep from rustying.Im thinking on water faucet pipe.
Might be a dumb question...
Is it safe to come in contact with food/drinking water once dried?
Really, how well does it adhere to surfaces? You know, how some products like Caulk peel off like if it was a smooth surface, like if it was a casting medium for a mold.
Drill a hole in a wine bottle, Flex Seal the hole, fill it 3/4 of the way with Diet Soda, glue a Mentos to the bottom of a cork. Push the cork back into the bottle. Turn the bottle upside down. See if the cork or the hole blows first.....
David Monroe sweet idea
Okay so I tried this and the bottle nearly fucking exploded but the cork was the first to go
That's the best idea ever
Please make a video tag me lol
🤣🤣🤣
One side of the can - "Non Flammable Non Toxic Non Hazardous" Other side of the can - "CAUTION: COMBUSTIBLE LIQUID HARMFUL IF SWALLOWED" So which one is it Flex Seal?!
Before and after use....
Also, swallowing fast drying liquid rubber might not be so good for the throat and stomach although, it would be hard to accidentally do that
After it dries.
so i think what it means is that it technically isn’t chemically hazardous but having liquid rubber solidifying in your stomach isn’t necessarily safe. as for the flammability contradiction, no fuckin clue
Flammable and harmful when in liquid form... Non flammable, and non toxic when cured. The toxic part is the evaporative solvent.

I just recently got into smelting lead to make diving weights,is this a suitable product for multiple salt water applications
Can it be used to seal a 75 psi 210° steam pipe?
I wonder can it hold good at high temperatures?
You should paint it on a pieces of different materials (wood, shingle roof, sheet metal, glass) and expose those pieces to the elements for a year and see what happens after a year of abuse!
It would be great to see how it holds up, but it is specifically designed as a temporary solution to a leak
I have seen all the ads. I never heard the word "temporary"
*_N O W T H A T S A L O T T A D A M A G E_*
This stuff will not last 3 months, Lloyd , roofer 35 years.
Roofers don't want to lose business, not sure I can trust their testimony.
Great video. I agree completely. I don't know why this stuff gets a bad rap, it's been great for my purposes.
Great video, thank you. I'm making an outdoor wreath out of cardboard and paper towel rolls. I want to use flex seal to waterproof it and I wanted to know if after it is completely dry if it can be spray painted and if the paint will stay nicely or peel off? I would use a krylon paint I think?
How hot was it when you left the tool in the sun?
Could this be used for exterior retaining walls that have slight cracked ? Will it stick on the wall and can it be painted after it has cured for 30 days? Thanks and great video!
Danny McBride and Cleveland Brown's voices made a baby.
Oh and good review.
Rory Baranyai that's hilarious!

Can I use this to seal a slow leak on asphalt shingle roof with skylight?
The real question is.... How long does it last after it's applied????
*exclamation point*
IL13 -exclamation point-
*_EXCLAMATION POINT_*
does not look bone dry at 6:04 . there is a hint of water near the edge.
joel castro that time stamp is just the guy talking...
8:05

He may not have let the Flex Seal dry properly or completely between coats. Because the rest of the board seems dry. I'd say it worked.
Flashing on the roof around my fireplace is letting water in, would this work to fix the leak?
Why use anything else?
But can it SEAL MY EX WIFE'S MOUTH SHUT!?
shit my nigga u gotta try that for your own
karl28560
If you try it, let me know how it works! But I might need 2 gallons... SHE HAS A HUGE FRIGGIN' MOUTH!
😃
Showing the body off
karl28560 bro you are a savage I respect dat
karl28560 You should try that
Been 4 years How is the review? Has it held up over time?
Can i paint this on the liner of my pool if it is dry? The wind blew it over and has a few little holes in it?
Had a bad vaccum leak on a plastic intake on an automobile throwing engine codes. Bad location. Used the flex seal spray and my headaches were over. I wish they would attach a straw or tubing to the end of the can to pinpoint spray. I know it would have to be made out of material that wouldnt clog but it would make applying spray that much better for hard to spray places
Nice job. But I need to know if it be applied 'under' water?
Just as Flex Seal did with their aerosol product I imagine that they will offer a greater color selection after the product is on the market for a longer period of time. It's to see if it will be a seller
will it cure underwater?
How long will that $90 can be good after opening and using a small amount? Seems like it would set up and be unusable.
Can you use on a shower where stupid installers left a gap between the tile and shower pan where water and mold is accumulating.
How do you paint this material I put it down in the bathroom and read some reviews it was paintable but it’s resisting the paint suggestions
can you use it to fix a Crack in a swimming pool?
i would use flex tape because since this is liquid and your pool contains liquid the flex seal will fill up you pool so use flex tape
Medward21 can u fix your bath. tub carcks wit it ????
probably since it's waterproof so yeah
if it is a hard in ground pool then it should work just let it set for a day or two like paint but make sure you get it in to the crack
Nagy Nageb yes
Do you think this would work good on the bottom of a metal kitchen chair..
I have metal kitchen chairs the plastic on the bottom has worn off and now it's metal on ceramic causing rust on my floor
I've been looking for something that will go on the bottom of my black chair legs that will last when people sit on it and stop the rusting
I figured I would dip the chair right in the flex liquid just enough to cover the bottom and then let it dry..
What do you
CAN IT BE PAINTED OVER
Put a small hole in a water hose. Seal it. Then turn water on. Will it still hold?
I enjoyed your demonstration for flexseal. However this product does and absolutely will break down over a period of just a few weeks to a few months depending on the application. It breaks down in direct and indirect sunlight. I have used the white, black and clear, and they all break down over a few months in outdoor conditions.

it makes me sad that you dont get more views. I love your reviews like i have said before. I appreciate that hard effort it takes to put out these videos. always looking forward to the next one. thanks JD
You sound like Cleveland Brown
i think he is
I accidentally wandered into this but I just gotta say its a great review, thoughtfully done and very well presented!
does it have a rubbery feel when applied to wood?
I'm building a koi pond and I have a concrete foundation do you think this will be a good recommendation to seal the concrete
Is it safe to kois if I use it to fix my outdoor pond.

I’d go with polyurethane the surface might be better for your application
My rear differential has pinholes in it and is leaking dif fluid . Do you think i can seal it with this?
would this be good to paint in the bottom of my Jon boat?
what I like to see is the flex tape ... can it hold up to the pressure, can you use it to fix a slashed Tire on the side not on the tread
I'd like to know how much each sized can will cover ... Nothing on their website either.
Can I use this on my gutters and roof for temporary fix for the winter
u can use it on gutter for permanent fix roof temp yes of course thats what it was originally designed for roofs

Will it seal my driveway's asphalt contact with the asphalt street (where it crumbles)?
How about flex seal underwater with pool tiles?
Yes, it holds up under water very well!

Thinking of trying this on my hockey sticks. How easy is it to remove? Can it be cut and peeled off with a razor blade for example?
Hey man do you think that stuff will stick to leather
Once you open the can it will go bad (set up in the can) is there any way to stop this?

How about painting your piece whatever color you want and then applying clear Flexseal??
Will this product work on a hole in the bathtub? Not fiberglass.
can it be thinned with water to be sprayed out of an HVLP sprayer?
Great stuff! BUT, you cant paint on it. Latex paint will not stick to it. Also has a weird smell so make sure you have good ventilation
Did you flex seal that snappy head covering you are sporting?
Dear sir is it hard to handle weight
Can color be added to the white Flex Seal liquid?
I need some of this to seal the outside of my shed floor so rain won't come in. Do you think it will work for that?
You should do an update on stuff you flex sealed
Can I use this on my inground pool? Its got some minor craking. No leaks though. Just some flaking off the walls and some in the bottom.
*exclamation point*
This is how many times he said "exclamation point"

How durable would you say that stuff is? Like if a person was to overcoat a PU shoe sole with multiple coats, do you think that stuff would hold up?
