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.
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!
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!!
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.
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 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.
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!!
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 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.
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!
He did. Check out: ua-cam.com/video/htcG8P0XeMo/v-deo.html. Then he went back and reviewed the job 8 months later: ua-cam.com/video/iY0fTLKFcTM/v-deo.html
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.
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.
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
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.
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.
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
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.
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.
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!
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.
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.
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.
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.
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!
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.
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.
A superior substitute to RedGuard/Aqua Defense? Perfect for shower pans would only take a few pails of flex paste. I wouldn’t use it on walls cause you can’t use ThinSet, I just buy backer-board with a built in waterproofing membrane.
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.
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 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 .
Still waiting for a GoBoard review by the way. Just got a local supplier for the stuff but I haven't used any of the foam products yet. It's a lot cheaper, so I'm wondering if there's a catch.
I love Goboard. It is very light and easy to cut. Thinset applies and holds very well even for large profile tiles. It is more expensive than cement board which I will never use and much cheaper than wedi or schlueter.
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.
Great video and it prompts a questions. The guy who just did our tile shower remodel did hot mopping on the pan, but he flex sealed the seat that we had put in. Given the lack of thinset bonding, do you think I'm gonna have problems?
If the cementitious stuff doesn't stick to the flex-seal, how are you going to keep the grout in? I don't see an advantage over redguard or such. Especially considering that stuff is pricey.
I would think the grout that has silicone in it would work but regular grout should still stick to the sides of the tile. My question would be how spongy it would be as to not move and crack regular grout. Don't know has me.thinking though.
I never thought of grout as needing to "stick" to the sub straight, so much as lock all the tiles together. I always assumed that a solid installation to a sub straight with minimal movement was the most important factor in preventing grout to come loose.
Love the video!! I think you should build a mock up shower & run the mock up with a hot & cold water!! Make the mock just like a real shower..I would love to see you build the mock up & test the mock up..The only thing I would not be sure about is how long( time wise, months or weeks) to test the shower 3 to 4 times a day. Isaac keep up the good work & see you in your next video.
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…
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 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..
Acrylic shower bases are becoming very popular due r to the low cost , can you do a shower install with a pre manufactured lightweight base and standard tile walls ....?
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.
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 👍🏿👍🏿👍🏿👍🏿
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
would flex seal work on my mattress to keep MyPillow from falling on the floor and keep my mattress from getting soiled when I get much older! Great videos!!
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 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.

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 would use flexseal in a pan application, especially in an older wood joist home. still not sold on wall application.
I could never do one for a customer or for myself. Thank you for you coaching and your work.

I'd be interested in pressure testing over time with all of the walking on and off.
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'd worry about how it ages. For example, if starts to crack in 5 years that's no good.
Yeah I feel like there would have to be actual testing done. Not some in shop mini trials.
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.

@@typhan1647 2yrs. Isn't long enough. It needs to hold up in daily showers for 10+ yrs. Do u think it would?
@@joshuaallen5453 sooo 7,200 showers over two years isn't good enough?? bahahaha, ok. it far surpasses any caulk or silicon on the market
@@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.
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!
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.
That was a great test, love it. What about grout adhearing to the FlexSeal?
OH MY GOD. YOU MADE MY YEAR. THANKS SO MUCH. MEGALITE FOR LIFE BABY. AND YES, PLEASE MAKE A REAL SHOWER WITH FLEXSEAL. WOOHOO
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.
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
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'd actually wondered itself same thing, you did the leg work, the results were as I strongly suspected, apreesh your work.
If you use it on a customer’s home then I will be convinced, I trust your skill set and knowledge.
Phenomenal man! Thank you for doing this kind of testing - have always wondered about "alternative" products like this!
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!
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.
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 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!!!
How well is grout going to stick to the flex paste?
Good question
I'm interested in seeing this played out in an actual install.👍👍
A superior substitute to RedGuard/Aqua Defense? Perfect for shower pans would only take a few pails of flex paste. I wouldn’t use it on walls cause you can’t use ThinSet, I just buy backer-board with a built in waterproofing membrane.
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
Used it to rebuild a swamp cooler pan, never leaked.
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 have used it plenty of times for a couple of years now and never any call backs or problems
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 .
Still waiting for a GoBoard review by the way. Just got a local supplier for the stuff but I haven't used any of the foam products yet. It's a lot cheaper, so I'm wondering if there's a catch.
I love Goboard. It is very light and easy to cut. Thinset applies and holds very well even for large profile tiles. It is more expensive than cement board which I will never use and much cheaper than wedi or schlueter.
I used GoBoard 6 months ago. It's fantastic. Will never use cement board.
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 😅
Great video and it prompts a questions. The guy who just did our tile shower remodel did hot mopping on the pan, but he flex sealed the seat that we had put in. Given the lack of thinset bonding, do you think I'm gonna have problems?
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
This is awesome information I would love to see at lease one project with the flex seal on the substrate
If the cementitious stuff doesn't stick to the flex-seal, how are you going to keep the grout in?
I don't see an advantage over redguard or such. Especially considering that stuff is pricey.
I would think the grout that has silicone in it would work but regular grout should still stick to the sides of the tile. My question would be how spongy it would be as to not move and crack regular grout. Don't know has me.thinking though.
I never thought of grout as needing to "stick" to the sub straight, so much as lock all the tiles together. I always assumed that a solid installation to a sub straight with minimal movement was the most important factor in preventing grout to come loose.
I will be using it on my current venture........ Great work! Thank you
Love the video!! I think you should build a mock up shower & run the mock up with a hot & cold water!! Make the mock just like a real shower..I would love to see you build the mock up & test the mock up..The only thing I would not be sure about is how long( time wise, months or weeks) to test the shower 3 to 4 times a day. Isaac keep up the good work & see you in your next video.
Have you checked an MSDS sheet to see if it is safe (off gassing?) in an enclosed space?
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…
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'm going to use this week on a shower
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..
Such a cool service you are providing. I am learning a lot.
Acrylic shower bases are becoming very popular due r to the low cost , can you do a shower install with a pre manufactured lightweight base and standard tile walls ....?
Seems like a good repair alternative
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 have done your home work . Looks good to me. Go for it!
Yes I'd use the flex seal. Your test was very impressive. Thx
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.
what is that tensile strength tester that you are using?
Yes I would use the flex seal products after seeing what it really can do. Love the videos and information you provid.
I will use it but in my masterbath first before using at jobsite. Also, cost is another deciding factor. Thanks for all your education.
Guess it depends on the cost, any idea what it might cost vs a regular install?
I would use the flexSeal for a shower remodel and I was pleased with your video test.
Great video....a grand slam. I am seriously considering applying to my own shower floor project.
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 👍🏿👍🏿👍🏿👍🏿
I'm gonna use it this week on my shower. A. Customer agreed to let me use it as well.
How did it go?
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
Thank you for performing this test. Yes I am going to try the Flex Seal product
I wonder how the grout would hold up with the flex seal underneath.
you should use it! It would be fun to see if you can make it economical
would flex seal work on my mattress to keep MyPillow from falling on the floor and keep
my mattress from getting soiled when I get much older! Great videos!!
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.
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.
