I am a researcher in the field of respiratory care and I applaud your use of the scientific method to assess the use of alternative water proofing systems. We all need to utilize the scientific method to assess the interventions we utilize on a daily basis, especially systems we use to on a daily basis. Kuddos sir.
Flex seal needs to finance a complete shower job for the tile coach to demonstrate the awesome comparison to traditional applications to waterproofing. Turn that into a commercial no more boats made of chicken wire. come on Flex seal. indorse this guy plz.
My MAIN Flex!! Do thoust feel my love for 'thoust' products from afar? For thine cupeths DO runneth OVER!....with stockpiles of all things Flex! But HELL YA yall should hook this fella UP! He certainly deserves it but I would LOVE to see him build a tiled shower; start to finish with my beloved Flex!
Flex Seal is awesome! It can save your day. While everything failed, I used flex seal to fix my shower leak without tearing my shower apart. It worked! My cost is one can of flex paste for $14 that saved my leaking shower. My shower is 60 years old and the waterproof lining has disintegrated and water has seeped through the dry pack, hardy back, dry wall and into my closet behind the shower. Flex seal does the job. It bonds to multiple materials than anything else and this is the first thing I know that can be applied directly to wet surface. I love it.
Keep the videos coming!! I’m a contractor from Arizona and love working with tile. I enjoy your content so much and I always learn something. Thanks so much Isaac!!
Great investigative strategy and hypothesis testing. As others have questioned as well it's not only how durable are these products over time but also the impact of moisture and mold development.
Id like to see that same tensile strength test after the flex mockup and standard mockup have both been submerged in water for a certain period of time, in order to see how the flex paste handles being submerged in water
I'd like to see the additional step of grouting. Would the chemical difference between flex paste and regular cement based grout cause cracking problems?
My question is, if used for grouting, how's the finish cleanup. I imagine it might be a little messy/ sticky..? But I suppose with the right applicator and a steady hand, thing's can be kept down to the bare minimum.
I used Flex seal on my own shower and it worked like a champ! Water proofed my shower using all Laticrete products, wall board, sheet membrane, Hydro Ban and Laticrete sealer. The Flex seal worked better than the Hydro Ban and dried faster under the sheet membrane!
Yes! I would like for you to tile a shower with using Flex Seal! It would be great if it was sponsored by Flex Seal! Then check on it after 15 years. My tiled shower was built in a house having a crawl space. Due to too much deflection or the house settling the tiles cracked causing a leak that rotted the wood subfloor under the pan liner. I don’t think the pan liner was attached high enough around the edges of the shower nor was there a membrane on the subfloor. So, the shower failed after 16 years.
I congratulate you on a really great video. You are the smartest Tile guy I've ever seen!. coincidentally I stumbled upon you as I was trying to solve a mystery leak in my pal's tile shower. once I had the drain removed I could see the person who put the shower in was not a subscriber to a membrane, or related weep holes. The drain was unusual in that it was a cone shaped beginning at the bottom of the lip. There was plenty of room for water to get in there around the edge of that lip, The lip didn't overlap the tile, and because it was a lip there was no gasket underneath any water entering that little (1/8 inch) gap when straight down to the weep holes, & three bolt holes on the same plate. To route leaching water into the weep holes, but to keep the edge dry I bought a 3" toilet gasket and cut off all but 3/8 inch. Then made a bevel when the cone touched. Flex sealed it around the outside circumference & also the top where the cone would touch. It worked !! now weep holes only get wicking water .. while the flex sealed gasket won't let any "above the tile" water in. Youre videos are A-1 . Thanks for teaching me.
Wow!! Was considering using this very same technique but was hesitant to risk it .. but after seeing your video, it's decidedly perfect for our needs! Thanks TC!!
This is BRILLIANTLY exactly what I've been pondering on while planning my tiled bench shower so I never EVER have to flop around in a bathtub,unable to get out after slipping...again. Except it doesn't quite get to MY specific pondering. I knew Flex would work. I'm OBSESSED with most Flex Seal products and hit sales and resale sites for deals, as a daily troll! I have a literal stockpile of different Flex sheeet. Anywho.....I was HOPING to see if it was cost effective. I know this product is not cheap but I've yet to begin pricing out needed product list, therefor, am unaware how it stacks in that department. So I'd LOVE to see you do an entire job with it!! PLEASE!! Maybe even a sidexside price match of Flex and the comparative product you'd use OTHERWISE. Good works here! Again!! You've helped a lupus addled 52 yr old woman get quite a few diy projects done RIGHT. Onto the next! A tiled sit-down shower so I can STOP taking 3 hr long 'showers', while sitting on edge of tub. Washing a load of sopping towels every other day. Because my dad taught me at a young age. When it came to destruction of what you've worked your fingers to the bones for... Fear water.
Flexseal is nearly double the cost of redguard. A gallon of flex seal is $89-$99 and a gallong of Redguard is $60. Flexseal advertises up to 150 sq ft of coverage from a gallon, and RG 110 sq ft.
He did. Check out: th-cam.com/video/htcG8P0XeMo/w-d-xo.html. Then he went back and reviewed the job 8 months later: th-cam.com/video/iY0fTLKFcTM/w-d-xo.html
I guess you have to trust it...you tested it. Great video. Thanks for your video quality. I'm hard of hearing and every word was audible. And your editing is superb!
Very unusual and very convincing that it works well the only thing you might try is to soak the flex seal application under water for an extended period. Awesome work Issach.
First and foremost thanks for the video. In my company as a automotive and aircraft detailing service I am always looking for products to enhance what I do. What I have found not all manufactured products are all that great. The problem is that's what's out there and that's what we have to use sometimes. But as you have shown in this video when you go outside the box and you find other products that can do a far superior job why not use. As in your test you can clearly see the fail point was not the products that you were actually testing it was the actual backerboard the weakest link. I guess the only way you can truly tell how strong is is put a piece of steel behind it and then see how much tensile strength it has. Again awesome video.
I used the flex seal paint to create my own tub shower surround wall. I even took a shower niche by kerdi and used the flex seal paste to cover it. Then blended the niche into the surround with combo of both.
Happy to see video. I had planned on fixing the cracked shower base using fiber glass cloth and resin. Then topping it with flex seal to hold the tile. Really appreciate the video. Thanks again, Leo
First class analysis. I am repairing a bathtub wall that has plywood under the destroyed cheapo plastic liner and have been looking for an inexpensive, relatively easy to do solution. This looks like a good solution for me and having seen this vid I can proceed with confidence. I was thinking about putting primer on the flexseal and using stick on tiles, but I think that regular tiles using this method would work great and be less expensive than using stick on tiles. Thanks!
The real question is how does this stuff hold up over time. I would love to see how well this stuff would hold up in a shower. It would be interesting to see how things like cleanup work compared to regular mortar. People like to make fun of the As Seen On TV stuff, but some of their products are very good. The biggest problem with some of their products are the terrible commercials and the lack of need of some of them. I absolutely love my Ove-Glove in fact, I liked the first so much that I bought another one. I never have to worry about bumping my hands or wrist on a hot oven rack again.
I used this stuff in my float center. I seal up the bottom of my float tank. The flex seal is exposed to salt water and lots of shower water all day every day. I use this in place of caulking. Let me tell you it is legit. It has held up for 2 + years without needed to be replaced. I touch it up once in a while when a chunk gets dislodged from mopping. This stuff works wonders no doubt and I will vouge for it hands down.
@@typhan1647 I agree...I know the flex seal will hold up no doubt. Its def. A water sealer of tge best kind. I was speaking more than about the materials attached to it.
he says in a subsequent video that this stuff made him feel ill/light-headed....goes so far as to say not to use this IN peoples' homes. he should've removed this video a long time ago....and just left the update.
Was waiting for this video! Seems like it works as a waterproofing application. I'd be concerned with how the flex seal paste you used to bond the tile would hold up in a wet area. I think that would be another great test. Hopefully it doesn't react like mastic does to water. Wouldn't want to be the first to try this in a customer's shower though lol
why don't just use a good quality thinset? in a future video he says this stuff mad him feel ill. he should have but didn't mention that here. and no don't do this on a professional installation.
I would totally use it if you did first with another one of your extremely helpful videos on an actual shower installation. Thanks for all your videos I've been in the trade for 30+ years and still pick up helpful tips from your videos
I didn't scroll through all of the comments , but from what I read so far , I didn't see any questions about sanded or non-sanded " grout " adhering to the flex paste . So , that would be a good test and also a test to see how the flex paste holds up under water . What you have shown me so far and one personal trial run leaves me confident enough to use the flex seal liquid and the paste on my 2 up-coming bathroom jobs in my home . I have used the flex seal liquid on my metal roof to seal 2 seams and to seal around 2 vents trying to fix a " bad " leak . Since sealing those things , we have had several down pours and no more water penetration . Couldn't tell you which area was the culprit , but which ever one it was is sealed now .
Using ANYTHING that works well comes down to cost. Is the cost of the flex seal more costly than the other water proofing material (say Red guard or something else) ?.
I have used ShowerKote from Kote Products. 5 years and no damp or leaks from shower at all. Also it is totally transparent, so you can coat over tiles without spoiling the aesthetics.
For me, if the Flex Seal + Flex Paste method works equally as well as the usual tiling methods do, then it would depend on which method is more cost-effective.
I would be concerned of “flex”ing under the tile and having issues with cracking tiles. The point of cementitious products is to properly support the tiles.
@@Trucker-Belly; How's it going yeah I would definitely think both flex seal products would work just fine the only problem it's not cost effective I'll do things you could use.
That's the rub. From a strength and user friendly point of view, I don't see any issues. The main thing that will keep this from being used would be the cost. I can see it being 10 times the cost of conventional methods.
Ardex 8+9 is about $112 on amazon. That's for a kit that has 1 gallon of 8 and a bag of 9.. so more than enough for a large home shower project. ..and maybe 10 other shower projects.. Flex Seal looks to be about $90 a gallon.. so the real question is whether or not you'd need more than a gallon to water proof your shower. If 1 gallon is enough, Flex Seal is actually cheaper and won't leave you with a lot of unused product. But if a gallon isn't enough then 8+9 is going to be more cost effective. Aaaaaand then there's the part where Isaac demonstrated you'd want to buy Flex Paste to use as thin set over Flex Seal, and that definitely costs more than the standard thin set that works with 8+9. So there's where the balance tips back in favor of using 8+9.
My roofer told me that there are more and more guys in his trade that think highly of Flex Seal and its usages. I can't think of a more unforgiving application than a rooftop.
That Flex Tape is no joke! You can apply it to the bottom of a cracked fiberglass tub and it will stop the leak 100%. Customer can use the fixture until I can get out there to repair. A month later it's a job to pull it off. A real tile guy knows all this Red Guard, ect and boarding up showers is a joke anyway, Flex Seal couldn't do any worse IMO.
I would try it in my own shower. One thing I used Flex seal for is sealing over a water stained drywall ceiling. After fixing the actual leak, the remaining water stain will bleed through several coats of normal ceiling paint. By spraying on some flex seal on the water stain before painting, the water stain no longer bleeds through.
Awesome video I’m going to use it on a shower build along with waterproofing the boiler room in the basement thanks for the great click keep them coming!
Yes sir! We have used the flex seal paste in white to seal our above ground pool skimmer…with it actively leaking. It took a light sanding, and two coats. The clear spray saved my basement from flooding when the pointing in the brick beneath the door failed to prevent water that would accumulate any time the French drain had something blow into it.
I can’t wait to see you build a shower with all those cool products that work. Get on it and thank you for all your informative videos. I appreciate you..
I have used flex seal on cracked commercial drainlines where the cost to repair correctly would have been astronomical due to bad access. 5 years later the repairs I made are still water tight and super well adhered. Flex seal would be a great solution for a pan that needs to hold water because it is a less likely to have issues in corners and seams (the areas all current waterproofing techniques struggle unless perfectly installed) because it doesn't have a tendency to crack when drying. the issue is the inability to use thinset means it is a pricey install.
Either get Flex Seal to sponsor a shower install (put their money where their mouth is and if it fails before it's due they pay for replacement) or try and persuade Home RenoVision DIY to do it instead, they'll use anything.
Jeff is OUTSTANDING. I don't know YOU but I'd still bet HIS experience compared to YOURS or many TODAY there really isn't much comparison. You say HE'LL use anything as if he were a gypsy.
After seeing a test of it, honestly I'd probably try it and would love to see it tried! Could be on to something! Most likely would want to try it a fake shower or something before a customer but sometimes can jump out of comfort zone! Awesome video
I've been watching all the flex seal commercials and have used some of their aerosol products. I would try it on a home project first and am pretty confident it would hold up in a tiled shower application.
I see others have asked about the price comparison to the products you use regularly and I would think it would run a but higher then normal at 90 dollars a gallon unless you can get a contractor discount. Also the snell is crazy and in a small area I believe it would be overwhelming. Also the work time of the product is very short from my experience with it but I definitely would love to see it done and I love the product and have used it around basement windows pipes running through walls and many other places. You do a wonderful job on your videos I was born into the masonry trade began at 8 years old dragging 8 inch block but still trying to master tile just a different animal all together yet very similar to cultured stone applications in some ways. Keep up the good work.
Man, I’d love to see you use this on a real job. I don’t think I’d personally feel comfortable using it on a customers job, until I’d lived with a shower done like this in my house for a while…
Matthew, I am using FlexGlue (clear) to install a combination of glass, tiles, and sea glass on a vertical brick wall. It is actually the wall above a fireplace. It is working great. I use a caulking gun to apply it.
Whoa! I would definately try this on my own shower project! If that worked well over say a year I would talk to a customer and discribe the install to see what they thought. If I had confidence in this method and the client was down, I give it a shot. I am curious about how grout would set between tiles and if so what grout would hold up the best.
I think it would work and I would use it, if the price is right. Otherwise due to price restrictions I would use it. Thank you for doing all that research.
I have so many questions about this!!! I’d let you try this on my shower! I’m in the building stage of my shower and after watching so many of your “fail” videos I’m skeptical to install the kerdi system as per instruction. Seems like there should be a better way to waterproof a shower in this day and age. Not saying FlexSeal is the answer but there must be a better way. Lol! Thanks for all the great content
Interesting... i used this stuff for extra sealing after rust conversion on an automobile as an under- coating and removed a small square to check 2 years later that did see a lot of action moisture-wise... I have to say I was impressed.
That was really great definitely educational and definitely worth a shot with that information it's a no brainer for me because of cost efficiency 👍🏿👍🏿👍🏿👍🏿
Since it's a petroleum based product, it should be acid and alkaline resistant. It's true enemy would be non volatile solvents, which you would never see in a shower.
I have used flex seal to stop leaks in a boats and I have seen it on roofs also. It seems over time it will break bond and flake away from having water on it, off and on. Using it in a shower would worry me due to the prolonged use of the shower with heat and cold. If it was a lake cottage or a vacation home that only gets used a couple times a year I would feel comfortable. It would be a fun video though. Cheers man!
Using flex seal would be like getting married. You hope and expect it to last. If it fails, it will cost you dearly as well as be heartbreaking. One difference is that the divorce will leave you high and dry. The failed flex seal will just leave you soaked.
The same is true for ANY waterproofing method...if it fails it will cost you dearly and leave you soaked. Question is, does this last longer than other methods of waterproofing.
Loved the Demo I have actually used flex seal in a can to seal some tough corners, but to use the flex seal products on a job is not practical to expensive .
AMAZING video! ! I'd like to see the result of it being used on an acutal job in home climates where expansion and contraction happens through the seasons.
You are awesome! I am learning a bunch with your channel. I love it. I’m in the trade as well, just started to get familiar with tile work for bathroom renovations and tile prep and installation methods in general. Thank you for sharing your knowledge. You are putting money in my pockets, for real.
I would have liked to see the tile bonded with Flexseal submerged in water to see how well it holds up. Another product you may consider testing is Liquid Nails heavy duty, under $4 at Wal-Mart. It has waterproofing properties, I'm using it to seal and bond the cement board joints and screw holes. I'm still using the mesh tape on the joints and waterproofing the entire cement board with RedGuard.
I don't know if I'd use it right now. BUT, I think it's worthy of further long term testing. It shown itself to have potential. And that's better than some other products out there.

Mortar cracks quicker than that.
I was thinking the exact same thing.
@@waynehead4902 Mortar is not considered a waterproofing agent. This would be in place of Red Guard or a hot mop install.
Shrinking maybe too?
Using ANYTHING that works well comes down to cost. Is the cost of the flex seal more costly than the other water proofing material (say Red guard or something else) ?.
I think 1 gallon of flex seal might be a little cheaper than 1 gallon of redgard. But the flex paste is most definitely more expensive than thinset.
I have used ShowerKote from Kote Products. 5 years and no damp or leaks from shower at all. Also it is totally transparent, so you can coat over tiles without spoiling the aesthetics.
Yes I will feel very confident that this is a very good product as red gard , thanks for your videos and your time to teaching as
For me, if the Flex Seal + Flex Paste method works equally as well as the usual tiling methods do, then it would depend on which method is more cost-effective.
but flex is total water proof
Awesome I'm fixing to repair my mother in laws tile shower pan I definitely want to see more coach
I would be concerned of “flex”ing under the tile and having issues with cracking tiles. The point of cementitious products is to properly support the tiles.
@@Trucker-Belly; How's it going yeah I would definitely think both flex seal products would work just fine the only problem it's not cost effective I'll do things you could use.
I actually did one 4 weeks ago and haven’t had any issues so far. Wish I could add pictures to the comments to send. Came out really well!!!
What is the cost of this as compared to a conventional install?
Good question
It's very expensive it's like $29 I believe for a pint not worth it
That's the rub. From a strength and user friendly point of view, I don't see any issues. The main thing that will keep this from being used would be the cost. I can see it being 10 times the cost of conventional methods.
This is probably one of the biggest questions. FlexSeal products seem to be pretty expensive.
Ardex 8+9 is about $112 on amazon. That's for a kit that has 1 gallon of 8 and a bag of 9.. so more than enough for a large home shower project. ..and maybe 10 other shower projects..
Flex Seal looks to be about $90 a gallon.. so the real question is whether or not you'd need more than a gallon to water proof your shower. If 1 gallon is enough, Flex Seal is actually cheaper and won't leave you with a lot of unused product. But if a gallon isn't enough then 8+9 is going to be more cost effective.
Aaaaaand then there's the part where Isaac demonstrated you'd want to buy Flex Paste to use as thin set over Flex Seal, and that definitely costs more than the standard thin set that works with 8+9. So there's where the balance tips back in favor of using 8+9.
My roofer told me that there are more and more guys in his trade that think highly of Flex Seal and its usages. I can't think of a more unforgiving application than a rooftop.
That Flex Tape is no joke! You can apply it to the bottom of a cracked fiberglass tub and it will stop the leak 100%. Customer can use the fixture until I can get out there to repair. A month later it's a job to pull it off. A real tile guy knows all this Red Guard, ect and boarding up showers is a joke anyway, Flex Seal couldn't do any worse IMO.
@@billysyms5761 Red Guard works just fine as long as you apply it properly. Red Guard over concrete backer board is bullet proof.
I would try it in my own shower. One thing I used Flex seal for is sealing over a water stained drywall ceiling. After fixing the actual leak, the remaining water stain will bleed through several coats of normal ceiling paint. By spraying on some flex seal on the water stain before painting, the water stain no longer bleeds through.
You can also use oil based kilz in a spray can it seals the stain and you can paint over it and the stain doesn’t bleed through
Awesome video
I’m going to use it on a shower build along with waterproofing the boiler room in the basement thanks for the great click keep them coming!
We need to see how the Paste performs when submerged, don't we?
Should perform similarly to the regular pourable FlexSeal.
Good question
I'd be interested in pressure testing over time with all of the walking on and off.
OH MY GOD. YOU MADE MY YEAR. THANKS SO MUCH. MEGALITE FOR LIFE BABY. AND YES, PLEASE MAKE A REAL SHOWER WITH FLEXSEAL. WOOHOO
Yes sir! We have used the flex seal paste in white to seal our above ground pool skimmer…with it actively leaking. It took a light sanding, and two coats. The clear spray saved my basement from flooding when the pointing in the brick beneath the door failed to prevent water that would accumulate any time the French drain had something blow into it.
I can’t wait to see you build a shower with all those cool products that work. Get on it and thank you for all your informative videos. I appreciate you..
I'd actually wondered itself same thing, you did the leg work, the results were as I strongly suspected, apreesh your work.
I have used flex seal on cracked commercial drainlines where the cost to repair correctly would have been astronomical due to bad access. 5 years later the repairs I made are still water tight and super well adhered.
Flex seal would be a great solution for a pan that needs to hold water because it is a less likely to have issues in corners and seams (the areas all current waterproofing techniques struggle unless perfectly installed) because it doesn't have a tendency to crack when drying. the issue is the inability to use thinset means it is a pricey install.
If you use it on a customer’s home then I will be convinced, I trust your skill set and knowledge.
Yes, please apply this methodology on the next job site! Can't wait...
I think I would use it on my own shower first, it's a great idea i'm always looking for products that really work... thank you for making your videos!
i would use flexseal in a pan application, especially in an older wood joist home. still not sold on wall application.
Either get Flex Seal to sponsor a shower install (put their money where their mouth is and if it fails before it's due they pay for replacement) or try and persuade Home RenoVision DIY to do it instead, they'll use anything.
'perfect everytime!'
👏🏼👏🏼👏🏼
Jeff is OUTSTANDING. I don't know YOU but I'd still bet HIS experience compared to YOURS or many TODAY there really isn't much comparison. You say HE'LL use anything as if he were a gypsy.
That would be the response we are really hoping for 😅
After seeing a test of it, honestly I'd probably try it and would love to see it tried! Could be on to something! Most likely would want to try it a fake shower or something before a customer but sometimes can jump out of comfort zone! Awesome video
I have used it plenty of times for a couple of years now and never any call backs or problems
I'm interested in seeing this played out in an actual install.👍👍
Such a cool service you are providing. I am learning a lot.
I've been watching all the flex seal commercials and have used some of their aerosol products. I would try it on a home project first and am pretty confident it would hold up in a tiled shower application.
Phenomenal man! Thank you for doing this kind of testing - have always wondered about "alternative" products like this!
I will use it but in my masterbath first before using at jobsite. Also, cost is another deciding factor. Thanks for all your education.
I see others have asked about the price comparison to the products you use regularly and I would think it would run a but higher then normal at 90 dollars a gallon unless you can get a contractor discount. Also the snell is crazy and in a small area I believe it would be overwhelming. Also the work time of the product is very short from my experience with it but I definitely would love to see it done and I love the product and have used it around basement windows pipes running through walls and many other places.
You do a wonderful job on your videos I was born into the masonry trade began at 8 years old dragging 8 inch block but still trying to master tile just a different animal all together yet very similar to cultured stone applications in some ways. Keep up the good work.
I will be using it on my current venture........ Great work! Thank you
Yes I would like to see it on a regular every day shower and see how it stands
Man, I’d love to see you use this on a real job. I don’t think I’d personally feel comfortable using it on a customers job, until I’d lived with a shower done like this in my house for a while…
You have done your home work . Looks good to me. Go for it!
I think this is a great product to try on curbs! Gotta believe it would hold up well!
I would be interested to see if you can set tile on a vertical wall. With the tiles start to sag
Make a test it's simple
Matthew, I am using FlexGlue (clear) to install a combination of glass, tiles, and sea glass on a vertical brick wall. It is actually the wall above a fireplace. It is working great. I use a caulking gun to apply it.
Whoa! I would definately try this on my own shower project! If that worked well over say a year I would talk to a customer and discribe the install to see what they thought. If I had confidence in this method and the client was down, I give it a shot. I am curious about how grout would set between tiles and if so what grout would hold up the best.
Great video....a grand slam. I am seriously considering applying to my own shower floor project.
I don't know why but it feels wrong using that product.. but it's good to know it works i guess in case of emergency or a repair of some sort.
Yes I'd use the flex seal. Your test was very impressive. Thx
I think it would work and I would use it, if the price is right. Otherwise due to price restrictions I would use it. Thank you for doing all that research.
I'm gonna use it this week on my shower. A. Customer agreed to let me use it as well.
How did it go?
I have so many questions about this!!! I’d let you try this on my shower! I’m in the building stage of my shower and after watching so many of your “fail” videos I’m skeptical to install the kerdi system as per instruction. Seems like there should be a better way to waterproof a shower in this day and age. Not saying FlexSeal is the answer but there must be a better way. Lol! Thanks for all the great content
Interesting... i used this stuff for extra sealing after rust conversion on an automobile as an under- coating and removed a small square to check 2 years later that did see a lot of action moisture-wise... I have to say I was impressed.
Thank you for performing this test. Yes I am going to try the Flex Seal product
That was really great definitely educational and definitely worth a shot with that information it's a no brainer for me because of cost efficiency 👍🏿👍🏿👍🏿👍🏿
wonder how flex seal and flex paste would hold up to cleaning products and soap/shampoo.
Since it's a petroleum based product, it should be acid and alkaline resistant. It's true enemy would be non volatile solvents, which you would never see in a shower.
I have used flex seal to stop leaks in a boats and I have seen it on roofs also. It seems over time it will break bond and flake away from having water on it, off and on. Using it in a shower would worry me due to the prolonged use of the shower with heat and cold. If it was a lake cottage or a vacation home that only gets used a couple times a year I would feel comfortable. It would be a fun video though. Cheers man!
I would use the flexSeal for a shower remodel and I was pleased with your video test.
We’re doing my father in laws shower this week and using the Flex Seal & Flex Paste. Pre-slope is done so here we go!
Yes I would use the flex seal products after seeing what it really can do. Love the videos and information you provid.
Based on your results, I would use it on a personal shower and see it over time. Can't "guarantee" it for a customer...yet
Using flex seal would be like getting married. You hope and expect it to last. If it fails, it will cost you dearly as well as be heartbreaking. One difference is that the divorce will leave you high and dry. The failed flex seal will just leave you soaked.
The same is true for ANY waterproofing method...if it fails it will cost you dearly and leave you soaked. Question is, does this last longer than other methods of waterproofing.
I would absolutely use Flex Seal after watching your testing.
Great video. Try mixing into or dusting the Flex-Seal with fine bed sand and I believe that the thin set will stick. Thank You
Loved the Demo I have actually used flex seal in a can to seal some tough corners, but to use the flex seal products on a job is not practical to expensive .
I’d love to see it applied in some capacity, if it works I’d be curious how it is cost wise to other products
AMAZING video! ! I'd like to see the result of it being used on an acutal job in home climates where expansion and contraction happens through the seasons.
Used it to rebuild a swamp cooler pan, never leaked.
Issac could you please do a video of a spray on truck bed liner test. I have been thinking of doing it for a shower one day.
Looks real convincing & it looks like it’ll do the job. I would like to see you pull it off I have faith in yuh.
I would use it but I think it would depend on the cost comparison. Would love to see you do an actual build with it.
You are awesome! I am learning a bunch with your channel. I love it. I’m in the trade as well, just started to get familiar with tile work for bathroom renovations and tile prep and installation methods in general. Thank you for sharing your knowledge. You are putting money in my pockets, for real.
I would have liked to see the tile bonded with Flexseal submerged in water to see how well it holds up.
Another product you may consider testing is Liquid Nails heavy duty, under $4 at Wal-Mart. It has waterproofing properties, I'm using it to seal and bond the cement board joints and screw holes. I'm still using the mesh tape on the joints and waterproofing the entire cement board with RedGuard.
I don't know if I'd use it right now. BUT, I think it's worthy of further long term testing. It shown itself to have potential. And that's better than some other products out there.
You’re the greatest dude in the world.
