Thank you for keeping the videos coming. I've been building houses for years. But I still learn something when I watch your channel. Your a good teacher man.
I see that you waterproof your drains now after you made that video where the drains waterproof fabric failed, that’s awesome, I too should start doing this.
Anyone watching this in the Uk 🇬🇧?? Do they not have Wetroom former trays in the States? Creating a fall in the joists with a ply over lay just seems like what people were trying to do over here 20 years ago 🤔
I’m a DIY guy so limited experience but that makes a lot of sense to me. Kerdi band and Kereck (corners) can produce significant build up over the base layer. I’ve heard of guys treating that issue by building up thinset to smooth out the difference similarly to taping Sheetrock. I don’t think thinset is made to do that. Using hydroban in those limited situations would solve that. I’m not sure about covering all of the Kerdi membrane with Hydro ban.
@@dblarney8201 hydro ban will stick to about anything, it's superior in topical waterproofing. You pay for it for sure, the old saying "worth it weight in gold" it just might be. Lol
@@bryanseever5468 You’re right about the cost of Hydroban, but they’re not exactly giving away the Kerdi corners. On a simple shower with a tile floor and one custom niche the nickels start to add up quickly when you have to buy all those inside and outside corners. I’m thinking the system you use makes the most sense.
From a architectural engineering standpoint. I have designed hundreds of restaurants and always use Hydro Ban with membrane on slab, turned up walls in all washdown areas.
My wife and I did the same for our diy goboard shower. Followed the directions but then added the redgard tape in the corners and where the walls meet the floor. Then 2 coats of redgard on top. Since it’s our house, it seemed like an easy 2nd layer of insurance.
This defeats the purpose of sheep membrane I am not a big believer of sheet membrane due to the fact that mortar absorbs water over time and works it’s way through everything I love your work Isaac ! Seriously you take pride and joy in your work
Hope you will show installing the tiles as well. Please explain the height measurements for your "skip the bottom row " technique. I'm doing almost the same design right now , except standard drain instead of linear . I watch all your videos, and a fan.
Been doing the same for awhile i saw way too many drains leak,corners and benches. I do 6 inches each way per seem or anything where it overlaps. That been said i watch your videos to learn or see new methods, in life we never stop learning new things.
Coach still shell shocked from that linear drain that failed him, lol. But I agree -- membrane on the bottom with liquid coat is probably as bulletproof as you can get.
GREAT video. At 20+ minutes of work and minimal expense - you have to wonder: why NOT use both the sheet membrane and the liquid. At twice or triple the price, the peace of mind would be worth the investment.
The only argument I've heard is the possibility that water gets under the liquid and then can't escape in any direction, and can't be detected from the appearance of water stains, etc. From there, presumably, the water deteriorates one of the products until it fails. I don't buy it, but I'm not a pro either.
@fartpoobox ohyeah Yeah, I'm sure it's not an approved technique. What bothers me about the logic of the "moisture sandwich" is it requires the outermost material to have failed. So if that's your only material, you have a leak. The fact that an inner layer has stopped it doesn't make the situation worse in my mind. Installing per directions is the way to go, but there's a non-trivial level of skill involved with a lot of these materials. Applying the right amount of pressure, working fast enough but not too fast, etc. If you screw up, even a tiny bit over something that isn't mentioned in the directions, the system can fail. Like I almost never see it mentioned that you can't allow thinset to cure on top of Kerdi prior to laying an adjoining piece over it. You may have the 2" overlap, but if thinset cured on a layer first, you can't get those two membranes close enough to actually get the 48hr water resistance. For a pro working fast it's no problem. For a homeowner that does the corners and edges after work one day, and a sheet the next day, oops.
Great video . I've installed polysafe vinyls in showers for years .......wish you had been prepping the jobs for me . So many showers go wrong ......it's a massive job to put them right when they do . Keep up the good work 👍
i do double Waterproofing each time in my showers. I do a skim coat over either Kerdi, Prova or Hydroban membrane and then i go with a liquid Waterproofing on top.
Every shower I do I put in a vapor barrier, cement board, redgard, and pan liner over it. Water damage is expensive, going above and beyond to waterproof is cheap.
Im happy to see you use to Laticrete products, they are so much more higher quality than the other competitors. I encourage other professionals and DIYers to try them. Try the strata heat on next projects it much more flexible than ditra heat when it comes to wire spacing it! Great work, looks really nice ,that shower looked like a lot of fun to build to bad they are more rare cuz not many people have the money to pay for something like that. Hydroban can be used as a decoupling membrane as well if you apply two generous coats on substrate its that good.
Isaac, I am a union painting contractor. If you are every looking for a new career, you and that big ass 1950's paint brush can come on over and work for me. ;)
I love your attention to detail, professional skills, and great attitude. I don't know enough about the tile pan products like Tile Redi and KBRS, but they seem like they could be bulletproof alternatives for keeping water out? However, I don't see you using them, so just wondering why?
Curious to see what you did at the transition from bath floor to shower floor (left side of drain), where the bath floor goes from flush to ~an inch higher than the shower floor.
It amazes me that plywood continues to be used as sub floors in wet areas - there is a vast range of cement fibre engineered boards that will provide all that is needed - also please explain why there is a want or need to have the floor of the shower heated ?? Looking forward to a reply.
Hello Love your videos. They are very informative and help with decision making. I have a question that I can't seem to find an answer for. Do you know if kerdi membrane can be applied over VOG (vinyl over gypsum) panels that are used in mobile/manufactured homes?
Hi, Im a big fan of your job. I have two requests; 1- You said you did a pool job waterproofing but I couldnt find that video, can you share it? 2- You definitely need to share what brand you use to do a shower from begining to end. You have done so so many experiments on products but we cant keep up with it. Thanks for sharing your art.
I agree with double waterproofing. I use schluter with ardex8+9. I also use the Ardex instead of the thin set to bond all the band over all corners and seems. Then two coats of the Ardex over entire area that will be wet. Insurance that I will never get a call for a leak for sure. Bullet proof system how I do it.
@fartpoobox ohyeah "If the water gets through the first line of defence..." this doesn’t make any sense. If you have only one layer, same logic applies. Water touches the tile, goes through the thinset regardless. So there is always some residue water behind the surface on top of the waterproofing.
Great content. I was wondering if you have ever used Hydro-Blok and their shower system. I'm going to be building a zero entry shower on the second floor so low profile shower pan is a must. I'm not sure if you can use a dry mix for that shallow of a pan (1" at edges 48x60) or I'd just do that instead to get the weeping system you seem to prefer.
My second story bathroom flooded much of my house. I've done most of the repairs myself. After watching many of your videos I have become less confident on doing my shower myself. I called a tile guy to do the job but after he came to look at the job site he never returned. He won't even answer my texts. I wonder if it had something to do with me sending him one of your videos on how to hot mop the correct way, Hmmm. This house has already flooded 3 times. I need it done right. Can you recommend someone in Fontana, California? My house flooded about 3 months ago.
Hello coach, I am doing a similar bathroom same configuration, second floor, plywood with liner drain, ditra xl , but kerdi on walls, and kerdi board 55x55 pitched. I am looking for a few suggestions... why did you use a different membrane for walls and floor rather than kerdi? Is the multimax lite compatible with kerdi ? Would you consider it instead of a thinset from mapei? I am planning to apply 2 coats of hydro ban on top of everything even the floor board. I really appreciate some input. Thank you. Very helpful video.
You’re a Kerdi hydroban guy…. I did tub pull walk-in shower build.. used Kerdi pan. Go board walls. Kerdi band on pan/wall seams. Kerdi drain.. aqua defense n fabric on walls.. triple coated everything. Even over kerdi/thinset band seams…. It’s waterproofed…. Kerdi good. Go board walls good.. recommend them both
I never see hydro barrier being used. However, never to go over kerdi. I really feel like I should, but usually just lap over with cut sheets of kerdi and lap over 4" on each side. Any thoughts on using hydro barrier? It's mean stuff too. Not quite as aggressive as hydroban, but I trust it. Thoughts?
Why do you like that brush while using the waterproofing? I use a 4” chipper brush with much shorter bristle length. That stuff can start flinging around on me with monger bristles. So I’m curious why you like that one.
hey Coach! is it true that the base of the shower is sloped plywood? no mud pan, and no pre-sloped Schluter pan? Just a layer of plywood, then a layer of ditra mat, then a layer of sheet membrane, then tile on top? I am currently doing a similar walk in shower and would rather do it this way than doing a mud pan. also, I am currently debating about whether to put floow warming inside the shower or not. would you always do it?
If using the Schluter system, does painting the additional waterproofing layer over the surface of the membrane cause any problems with the schluter warranty? I can’t imagine that it would but wanted to ask. Love the channel! I have learned so much.
Yes it does I called Schluter to ask the same question. It will void the warrenty Schluter does not want you to use a liquid waterproofing over the sheet membrane.
Let's be real, the warranty on any type of product like this is worth the paper it's written on. They will find any way on earth to void your warranty, and likely even if you somehow get them to "cover" it they will likely just replace what product failed. Think: this 2sq ft area of the membrane failed so would you like a $4.50 refund or would you like us to ship you 2 Sq ft of new membrane?
I have always had issues with the thought of using morter to bond the two. Though it is a proven system. I like this piece of mind though. Second seal.
I wonder if painting this into the whole line drain could prevent the line drain failures that Kerdi is now having in 2023/2024 popping up here and there? Or would it make it so the grate wont fit in afterward?
sloping base and walls would be the same process with hardibacker/cement, but with hardi there would be less potential for sub flex and tile failure. Any reason you went with a plywood base and wall instead of hardi?
I just did a complete upstairs walk out shower with the Schluter system, shower pan, kerdi board walls etc. I used Schluter all set. Would it be worth it to add a coat of Hydro Ban Liquid membrane to the shower area? Would it increase waterproofing? Would Hydro Ban react negatively to Schluter all set?
Great Video and I'm in a similar situation now. Someone help me with this question. Ive got wonderboard on my walls and I want to redgard my wonderboard. Also, using kerdi system too so I have the kerdi membrane. Can I apply the kerdi membrane over the redgard wonderboard? I'm using the kerdi brand thinset.
How do you feel about bonding schluter membrane in the drain to laticrete membrane and band? What method do you use to bond the two systems? I started a schluter shower but can't get kerdi board now due to shortages. I have a schluter bench to install with hydrogen board now. Doing the same on floor as you did in the video. Can I just use multimax lite with the schluter bands that come with the bench?
I dunno the liquid apply would fuse to the fabric in essence it is like using crack isolation tape on your entire wall one of the weaknesses of fluid applied membranres. I would imagine using fluid applied over a properly done sheet membrane would just make it basically impossible to get a crack in the membrane.
Yo, I'm re doing my entire floor, everything except joists themselves, my question is how thick of plywood subfloor do I need between the joists and the Ditra pad when talking about natural stone marble and lime stone,..and is the same thickness required for engineered hardwood ?
Master Isaac (seriously), why did you put the bathroom drywall sheet there and not another sheet of hydro ban? It's a vulnerable spot outside of the shower door. I humbly ask you as your faithful student.
I'm currently doing a kerdi shower and although it is done to spec I'd like to do a double waterproof as well. What liquid membrane do you recommend over kerdi products? I've seen you use ardex 8+9 and hydroban
James-for what it’s worth, I just barely demo’d my master bath and did what you’re suggesting. I used 8+9 based on Isssc’s videos on top of kerdi and it bonded beautifully. Zero leaks when doing the water test. I would stick with 8+9 as the top coat over kerdi.
As a tile installer myself. We always talk about the dreaded term "failure". What does that mean to you? Obviously it's conditional. A dry floor failure could be a Crack, whereas a wet area would be a leak etc.
When you go home, you want to fall asleep at night and not wonder if that thing will fail in the future. So if it means doing overkill every job just to get a good nights rest..do it every time.
My tip: I waterproof to the next stud/Joist beyond the shower when waterproofing. Why? After years Sheetrock absorbs water/moisture next to showers and peoples 1st step out the shower is always dripping.
So, I did me first schluter shower system this month; I was so worry about the seams and corners that used 2 coats of redgard on all seams and 3 coats all over the bench. Drain was relocated to the center and flood test it for 24 hours. Will using the liquid membrane void schluter's warranty?
@@paulkiefer3893correct. If you use a mudbed you’ll put roof felt over the plywood first. Treated lumber shrinks as it dries out which breaks your bond to any concrete or mortar and your tiles can crack
BCX plywood. "X" = exterior glue. If your shower gets to the point where the marine plywood would be needed, you'd have bigger problems. (hint...water is not supposed to get to this layer)
I’m in Dallas and just finished a tub surround. There is no laticrete wallboard product (or schluter) available for waterproofing. No ideas when it will be available. !!!!
I purchased the kit online at Lowe’s, but I see many products at Floor & Decor in the Dallas area. Lowe’s and Home Depot have some of the products but not a full kit.
Thinset +Plastic and fabric = Waterproofing ? I have seen lot of those infinity linear drains leak. The glue just separate from SS drain body. Double systems and LM has been used since 20+ years ago by professional waterproofers.
Quick question and you’re not going to like this but i just sloped and floated a floor with wood and cement board as the flooring for a tiled tub, it was fine two days ago but today its been creaking when i step in it. Now question is; if I cake on my hydroflex and seam tape it real nice like how long till she quits on me?
@@TheBshackelford1 lol you should’ve seen it before! The toilet and tub were sinking due to rotted floor and joist that I had to tear out and replace. I wasn’t expecting having to completely replacethe plumbing all the way down to the crawl space and even then the cement tubing used was cracked and broken. I honestly think it will hold up decently at least five years, then ill go in and redo it because the house is 100 years old and I’ll be redoing a lot of it.
@@TheBshackelford1 I’m not done yet. I had to re-tuck the outside wall bricks surrounding my window aswell as change the window. I’ve been stalling a bit since there really is anybody who’s done this before. I’m gonna water proof and tile Tomorrow
do you think hydro ban will adhere to kerdi membrane with easy? i bought a kerdi shower kit and halfway installed.. do you think it will adhere good to there membrane??? i hope you see my comment..
Yeah it adheres fine. Beware the thickness of your coats, as this product does need to air dry. If you put it on really thick, the top will cure to a waterproof skin, and since you've put it on a waterproof membrane, the rest of the thick coat cannot ever dry out. So brush it on thin like a coat of paint, and don't let it pool up in corners and low areas. You can always add a second or third coat even, just keep them thin. There's also Hydroban Cementitious that comes as a powder you mix with water like thinset, and it cures like cement, chemically reacting with the water. It requires no air drying, and could in theory be put on much thicker. Isaac has used it too.
Doing double waterproofing might result in water getting trapped between the water proofing and not drying properly. In conclusion making it worse. All companies like laticrete and schluter will tell you to not do this. Is not necessary and is just a waste of money and extra work. Their membranes were made for this and as long as they are installed properly they will no fail.
I think a moisture sandwich involves a waterproof layer, then a non waterproof layer, then another waterproof layer. This is just two waterproof layers, so there's no "food" in the sandwich.
@Abdul Hai I'm not sure it's necessary, but it might be more durable. It might fill in any gaps in the other layer like a pinhole or abrasion. Maybe a similar idea to using two coats of paint to get better coverage? In any case, I don't see a moisture sandwich because both layers are waterproof and there's no material or air between them.
From what I understand, Schluter will warranty their drain, and laticrete will warranty their membrane. At least that is how Ardex, RSS, and FloFX approach warranty issues when mixing manufacturers. To be honest, if there is a failure with this system it’s 99% going to be an installer issue so warranty wouldn’t do anything anyways. Great question. Thank you.
Thats why i dont trust sheet membrane systems. Whats the point in even using it? I get that its faster but who cares if it leaks? Id rather spend 2 or even 3 days applying a liquid membrane that 100% wont leak than spend 1 day on a sheet membrane that keeps me up at night. Ill stick with Redgard. Been using it for 15 years without failure. I understand the Hydro- whatever is new and supposedly "better" but unless youve tested it personally for atleast 5 years, it doesnt mean anything to me. If every add copy and marketing slogan was true the world would be a completely different place. Ill stick with Redgard. But i appreciate the info. Love the channel.
I just don't get it ...it's like putting a can inside of a can inside of a can ?? Showers fail because of neglect .that being said I can understand in a multi storey residence
I've heard you shouldn't apply liquid membrane over a mud shower pan with a PVC liner because you may trap moisture. Is what your doing possibly causing the same effect? Liquid waterproofing over the ditra with thinset in between? I like your procedure but was wondering about that.
Thank you for keeping the videos coming. I've been building houses for years. But I still learn something when I watch your channel. Your a good teacher man.
Agreed... Issac's videos are incredibly informative because of his testing of products and process. Keep it coming Issac
I see that you waterproof your drains now after you made that video where the drains waterproof fabric failed, that’s awesome, I too should start doing this.

Need more videos about pricing coach !
This is excellent advice. Your the man.
I wonder if painting this into the whole line drain could prevent the line drain failures that Kerdi is now having in 2023/2024 popping up here and there? Or would it make it so the grate wont fit in afterward?
Do you think Liquid Flex Seal would work in places you would use liquid hydro ban, like in this job in this video???
your right about red guard it can bleed through the natural lighter color stone mosaic tiles. Yo Man bless up it's Mike with N2stone 💯😎👍🏼🙏🍺
Is this the first shower where you didn't use a tray (Kerdi, etc)? If not, about how many have you done?
can you paint over the liquid membrane, or it's only for tiling purposes?
sloping base and walls would be the same process with hardibacker/cement, but with hardi there would be less potential for sub flex and tile failure. Any reason you went with a plywood base and wall instead of hardi?
I just did a complete upstairs walk out shower with the Schluter system, shower pan, kerdi board walls etc. I used Schluter all set. Would it be worth it to add a coat of Hydro Ban Liquid membrane to the shower area? Would it increase waterproofing? Would Hydro Ban react negatively to Schluter all set?
Great Video and I'm in a similar situation now. Someone help me with this question. Ive got wonderboard on my walls and I want to redgard my wonderboard. Also, using kerdi system too so I have the kerdi membrane. Can I apply the kerdi membrane over the redgard wonderboard? I'm using the kerdi brand thinset.
How do you feel about bonding schluter membrane in the drain to laticrete membrane and band? What method do you use to bond the two systems? I started a schluter shower but can't get kerdi board now due to shortages. I have a schluter bench to install with hydrogen board now. Doing the same on floor as you did in the video. Can I just use multimax lite with the schluter bands that come with the bench?
Yes
Are there any concerns about or tips to avoid creating a “mold sandwich” when using multiple layers of waterproofing?
I dunno the liquid apply would fuse to the fabric in essence it is like using crack isolation tape on your entire wall one of the weaknesses of fluid applied membranres. I would imagine using fluid applied over a properly done sheet membrane would just make it basically impossible to get a crack in the membrane.
Another awesome video! Thanks brother!!
Yes
Yo, I'm re doing my entire floor, everything except joists themselves, my question is how thick of plywood subfloor do I need between the joists and the Ditra pad when talking about natural stone marble and lime stone,..and is the same thickness required for engineered hardwood ?
Would you do this step with the hydro ban if you had a schluter shower pan, wallboard, corners, etc. ?
Do you recommend hydroban over kerdi membrane?
Not sure why kerdi membrane was mixed the other brand (grey) membrane
Master Isaac (seriously), why did you put the bathroom drywall sheet there and not another sheet of hydro ban? It's a vulnerable spot outside of the shower door. I humbly ask you as your faithful student.
Can I use that waterproofing over densshield boards? Because I normally use Redgard!
I'm currently doing a kerdi shower and although it is done to spec I'd like to do a double waterproof as well. What liquid membrane do you recommend over kerdi products? I've seen you use ardex 8+9 and hydroban
James-for what it’s worth, I just barely demo’d my master bath and did what you’re suggesting. I used 8+9 based on Isssc’s videos on top of kerdi and it bonded beautifully. Zero leaks when doing the water test.
I would stick with 8+9 as the top coat over kerdi.
As a tile installer myself. We always talk about the dreaded term "failure".
What does that mean to you?
Obviously it's conditional. A dry floor failure could be a Crack, whereas a wet area would be a leak etc.
When you go home, you want to fall asleep at night and not wonder if that thing will fail in the future. So if it means doing overkill every job just to get a good nights rest..do it every time.
Could you use this same product on a shower that was waterproofed with Kerdi membrane?
Pretty soon he'll just be hanging green board and red guarding just like starrtile
My tip: I waterproof to the next stud/Joist beyond the shower when waterproofing. Why? After years Sheetrock absorbs water/moisture next to showers and peoples 1st step out the shower is always dripping.
So, I did me first schluter shower system this month; I was so worry about the seams and corners that used 2 coats of redgard on all seams and 3 coats all over the bench. Drain was relocated to the center and flood test it for 24 hours. Will using the liquid membrane void schluter's warranty?
Yes
Did it leak tho ha. I’m thinking of doing the same
What's the best plywood for the subflooring of the pan? Treated? Marine grade, or Glued osb like lp solutions?
Marine grade would be the best choice, sanded both sides, minimal gap or zero on plys and most importantly a water resistant adhesive.
Treated wood is not recommended for use under any of the membrane products.
@@Jakbkwik1 so use standard apa floor or exterior sheathing?
@@paulkiefer3893correct. If you use a mudbed you’ll put roof felt over the plywood first. Treated lumber shrinks as it dries out which breaks your bond to any concrete or mortar and your tiles can crack
BCX plywood. "X" = exterior glue. If your shower gets to the point where the marine plywood would be needed, you'd have bigger problems. (hint...water is not supposed to get to this layer)
Which Hydroban product would you recommend over Kerdi?
What are the shoes you are wearing?? I’m a installer and I’m alway looking for nice shoes
I live in the bay area California where can i find the hydroband and the foam board besides home depot and those big stores ?
Do you work in Florida?
I only use cast iron. You stopped floating? Boards are not good.
Is there a video where you tiled this shower?
I’m in Dallas and just finished a tub surround. There is no laticrete wallboard product (or schluter) available for waterproofing. No ideas when it will be available. !!!!
I purchased the kit online at Lowe’s, but I see many products at Floor & Decor in the Dallas area. Lowe’s and Home Depot have some of the products but not a full kit.
I talked to a schluter rep... schluter can't get the product to manufacture. Backlogs of backorders , it'll be awhile
Laticrete, Schluter, Sherwin Williams …none of them have mainline products …still. How do they stay in biz???
Can I go full Kerdi board on walls and shower pan but also use this on corners etc ?
Does anyone have any idea about the energy cost to run that much heating line through the floor?
What’s wrong with Redgard? It looks great to me.
With using best possible practices why don’t you run the line drain flap up the wall first then bring the sheet membrane over it
Right I’ve also thought about this
Thinset +Plastic and fabric = Waterproofing ? I have seen lot of those infinity linear drains leak. The glue just separate from SS drain body. Double systems and LM has been used since 20+ years ago by professional waterproofers.
Do have ditra heat in the shower or only outside??
Why don’t you guys do polyurethane all internal corners and 2 coat liquid membrane on fc sheeting?
probably will switch to that next week..
Quick question and you’re not going to like this but i just sloped and floated a floor with wood and cement board as the flooring for a tiled tub, it was fine two days ago but today its been creaking when i step in it. Now question is; if I cake on my hydroflex and seam tape it real nice like how long till she quits on me?
Wtf hire a professional before you ruin your house
@@TheBshackelford1 lol you should’ve seen it before! The toilet and tub were sinking due to rotted floor and joist that I had to tear out and replace. I wasn’t expecting having to completely replacethe plumbing all the way down to the crawl space and even then the cement tubing used was cracked and broken. I honestly think it will hold up decently at least five years, then ill go in and redo it because the house is 100 years old and I’ll be redoing a lot of it.
@@Wergrun how did everything go. Turn out ok?
@@TheBshackelford1 I’m not done yet. I had to re-tuck the outside wall bricks surrounding my window aswell as change the window. I’ve been stalling a bit since there really is anybody who’s done this before. I’m gonna water proof and tile Tomorrow
do you think hydro ban will adhere to kerdi membrane with easy? i bought a kerdi shower kit and halfway installed.. do you think it will adhere good to there membrane??? i hope you see my comment..
Yeah it adheres fine. Beware the thickness of your coats, as this product does need to air dry. If you put it on really thick, the top will cure to a waterproof skin, and since you've put it on a waterproof membrane, the rest of the thick coat cannot ever dry out. So brush it on thin like a coat of paint, and don't let it pool up in corners and low areas. You can always add a second or third coat even, just keep them thin.
There's also Hydroban Cementitious that comes as a powder you mix with water like thinset, and it cures like cement, chemically reacting with the water. It requires no air drying, and could in theory be put on much thicker. Isaac has used it too.
@@MrWhateva10 the hydroban cementitious does require air to dry. Ardex 8+9 does not need air. Maybe mixed the two up.
Doing double waterproofing might result in water getting trapped between the water proofing and not drying properly. In conclusion making it worse.
All companies like laticrete and schluter will tell you to not do this. Is not necessary and is just a waste of money and extra work. Their membranes were made for this and as long as they are installed properly they will no fail.
I think a moisture sandwich involves a waterproof layer, then a non waterproof layer, then another waterproof layer. This is just two waterproof layers, so there's no "food" in the sandwich.
@Abdul Hai I'm not sure it's necessary, but it might be more durable. It might fill in any gaps in the other layer like a pinhole or abrasion. Maybe a similar idea to using two coats of paint to get better coverage? In any case, I don't see a moisture sandwich because both layers are waterproof and there's no material or air between them.
Now I wish I hysrobanned my whole schluter shower
Can u use same method with kerdi foam and all kerdi produxts?
You’re cutting in like a painter 😂
using laticrete with schluter doesn't void the warranty on them?
Laticrete won't like that
From what I understand, Schluter will warranty their drain, and laticrete will warranty their membrane. At least that is how Ardex, RSS, and FloFX approach warranty issues when mixing manufacturers. To be honest, if there is a failure with this system it’s 99% going to be an installer issue so warranty wouldn’t do anything anyways. Great question. Thank you.
Thats why i dont trust sheet membrane systems.
Whats the point in even using it?
I get that its faster but who cares if it leaks? Id rather spend 2 or even 3 days applying a liquid membrane that 100% wont leak than spend 1 day on a sheet membrane that keeps me up at night.
Ill stick with Redgard. Been using it for 15 years without failure.
I understand the Hydro- whatever is new and supposedly "better" but unless youve tested it personally for atleast 5 years, it doesnt mean anything to me.
If every add copy and marketing slogan was true the world would be a completely different place.
Ill stick with Redgard.
But i appreciate the info. Love the channel.
Can sheet membranes tear when there is expansion
Anyone have link for ditra heat video he mentioned? I cannot find it
I just don't get it ...it's like putting a can inside of a can inside of a can ??
Showers fail because of neglect .that being said I can understand in a multi storey residence
I've heard you shouldn't apply liquid membrane over a mud shower pan with a PVC liner because you may trap moisture. Is what your doing possibly causing the same effect? Liquid waterproofing over the ditra with thinset in between? I like your procedure but was wondering about that.
hydroban is moisture permeable while the sheet membrane is not. It's fine for shower floors with liner
Exactly how I would have done it
