How to Install Schluter KERDI-BOARD in a Bathroom Part 1 (Step-by-Step)

[@sergioecg]

Hi guys, great video, one thing I would like to add, I have seen another video where the installer, seamed a very knowledgeable dude, when the walls were out of plumb, he did a tinset layer on the studs behind the kerdi board, then put the boards in and wiggle them till they were plumb and square perfectly for the tile to be perfectly square every where, waited a full day for the tinset to dry then did the screws. I understand you can do spacing or planner the studds to the point where they are all even but this way seams really kool and easy, down is it needs an extra day for the job to be done. Mainly for walls that are waky out of level / plumb. Keep the great work.

[@thevoigts651]

I so appreciate your videos. I'm an experienced woodworker / do-it-yourselfer, but have never done a tile shower before. I'm completely renovating both of our bathrooms. Thanks to your videos, I went with Kerdiboard and am in the process of installing it in the first bathroom as I type this. Every stud in our 50 year old house in the tub surround was either bowed or warped, so I had to screw studs to the existing ones to level the entire surround area up. I've been watching your tile install videos also. Thank you!

[@HomeRepairTutor]

Thanks Gary, sorry to hear your studs needed to be fixed. Sounds like you did a good job fixing them. What kind of tile are you setting?

[@thevoigts651]

I'm using the Marissa Carrera 10" x 14" porcelain marble look alike with bull nose from HD. I plan on whipping up a Sketchup mockup of the shower so I can get a good layout plan. I appreciate the detail and practical tips from you guys. I've watched a lot of videos and most of them don't even mention using a laser level, how to do niches, leveling tips, etc. like you guys do. I got thinset, grout, and supplies from a tile supplier vs big box store and I'm glad I did. They hooked me up with Bostic Ditra Set and Laticrete.

[@HomeRepairTutor]

Thanks Gary, another good tip with marble is to use white thin-set instead of gray. The pigment in gray thin-set can discolor the top of the tile over time. Our course over on Bathroom Repair Tutor might be a good option since you're doing two bathrooms. And we enjoy following our students and answering their questions through the entire remodeling process. Figured I'd mention that in case you were looking for a good resource.

[@thevoigts651]

It's actually porcelain, but thanks for the tip nonetheless. I'll have to take a look at your website. Thanks!

[@HomeRepairTutor]

Happy to help any time Gary, back buttering the tiles will help with your bond, too. Since the tile is in a wet area shoot for 95% coverage with thin-set on the back of the tile. Use at least a 1/4" x 3/8" square notched trowel if the tile is 1/4" thick.

[@WesterlyPrune99]

Done cement board and it’s annoying to deal with thought I’d give this a try but it’s really made out of foam? How would this hold up if you hit the wall by accident?

[@Shad0wC0mpany2]

Wondering the same!

[@brookemcquale5096]

A favorite practice of mine re: leveling wall studs, is to apply a 3/8" bead of e.g. pl-200 to the studs (severely warped studs, as indicated in this video require add'l attention) I then tack the board up to hold it in place while the adhesive sets, after which I add further screws. With Durock or Wonderboard type materials I pre-drill holes so as not to compress the adhesive. If you're lucky you may even be able to plumb the boards, assuming the studs aren't too out of whack. It adds strength and reduces board warp considerably. It's worked for me for decades.

[@HomeRepairTutor]

Awesome tip Brooke, thanks for sharing. Schluter also recommends adding thin-set to the studs and setting the boards over that while checking for plumb. I like your tip for the cement boards, many thanks.

[@brookemcquale5096]

I'm sure thinset is fine enough, but it sounds a bit inconvenient compared to applying a bead of adhesive. Also, there are adhesives that set up rather quickly if time is an issue. Some years ago I went to Aliquippa, Pa. for a several day seminar on Ardex products where I was rather amazed at the performance of them and have been using them ever since. Even after decades of doing tile work I learned some very useful techiniques (like not using the "swirl" method of troweling, although, I will say that I have always been a fan of "back-buttering and periodic checking of tiles to ensure entire coverage, because I have always used a slightly wetter mix, I never had any problems with the swirl method, but found using the linear method saved time. As for using more water weakening the ultimate tensile strength of the thinset, today's products are of such an overkill quality (in 90% of cases) I'm generally not concerned with whether or not the final product can resist a 15.5lb. bowling ball over a 15.6lb. one and haven't had any problems with separation (at least that have been reported back to me). For any of you tiling enthusiasts with money to burn, but also a strong desire to do great work, look into Karl Dahm tools. They're thieves to be sure (price-wise) but their products are among the best. Back to the Ardex products; I don't know if Ardex still gives seminars, but I would strongly recommend any serious tilers attending one (if feasible) when I went they put me up at a nice hotel and I met some very nice people with many useful tips. Another product I have been using for decades (it itself has been around since 1904) is Anti-Hydro, an additive for cement based thinsets and grouts (not epoxy) and concrete mixes. It waterproofs, strengthens, and makes grouts more colorfast (it doesn't improve adhesion as I've heard some people claim and the makers of it will tell you so). It's available on Amazon.

[@HomeRepairTutor]

We're very close to Ardex headquarters near Aliquippa, PA and highly recommend installers attend their seminars. We also work with them on some tutorials and have plans to make future videos with Ardex. Their tech support is excellent and they make outstanding products, hence our love for X77 modified thin-set and X5 for DITRA installation. I believe you're referring to directional troweling whereby all the trowel ridges face the same direction. We've had discussions with Ardex and the folks at CTEF on this topic. Our buddy Sal DiBlasi is also an advocate of directional troweling and CTEF. This method eliminates air pockets in the thin-set and provides maximum bond strength if the thin-set is mixed properly. We advocate reading and following the directions to a 'T' for thin-set. It's amazing the difference you'll see if the directions aren't followed. I'll have to look up the Karl Dahm tools. Thanks for the tip. We're currently testing Montolit tools and are very impressed with their performance. Again, not a cheap product but very good.

[@SgtZima]

That's similar to wet shimming using thinset.

[@jacquestitley1039]

Great video guys , I will be doing my shower this week and I have ordered my kerdi boards .

[@HomeRepairTutor]

Awesome! Definitely get KERDI-FIX for that tub to KERDI-BOARD transition. Not sure if you've got a tub but wanted to emphasize that tip.

[@pauloruiz8989]

I do mainly commerical flooring, but by the looks. If I do this shower i would work just like you, knocking there’s room to fix the imperfections or cover them with the tape no need to waste time making it perfect.

[@davidh4538]

If tub back wall is an exterior wall, in a cold climate, is a vapor barrier recommended or should you not use a barrier behind the kerdi boarrd?

[@stevepartridge6035]

Useful video, what was the metal corner guard product, it’s never mentioned what it’s called.

[@tonycarrillo1140]

jeff another question- the half inch thick works for all size tiles?

[@TEXASHANDYMANSVCS]

Thank you for taking the time to make your videos. Very helpful.

[@HomeRepairTutor]

Thank you, hopefully it has some useful tips

[@scottyboy2400]

Question please? - How far/deep do you drive the srews and clips into the kerdi? Like should there be a little bowl shaped indentation or should the clip be flat on the surface? It looked like this guy drove them in pretty good but would just like to verify. Thx!

[@1Esteband]

I went to the store today and checked it out. It worries me that a slip or kids hitting or pushing the wall would crack the tiles. It’s super flexible.

[@Shad0wC0mpany2]

Will they really crack though???

[@cathystadderwise2770]

Why no vapour barrier on insulation? Does Kerdi board serve that purpose?

[@JustinMentionedIt]

When do you use kerdi board instead of green board and kerdi felt?

[@antzooms]

any idea if i should still add a plastic 6 mill to cover the insulations? my bathroom wall on the other side is my garden

[@brotherjoeradosti]

What did you do for the seam on the ceiling? I see some guys tile up to the row before the niche before they install it so they can match up the grout lines. Schluter makes pipe and valve seals.

[@youtubesucks4257]

Dude! Protect that tub,Dammit!

[@benparsons196]

Do i use modified or unmodified all set to set pan and kirdi? How much do i need for 38x60 base and walls with curb and 2 niches.

[@rudysmachado5747]

GREAT VID! 1 smal ques., do u have to start w/ reer wal, or can u instal side walls first? Concern is 4 the 90 deg corners...any particular order? We’re gonna tape em anyway, rite?🤙🏻

[@one1wizard]

nice job on doing the shower, I see you do the same thing on the ball valves on installing the diverter. Question, why did't you cover the tub, your walking all over it. Good way for it to get damaged.

[@maggseb]

Can Microcement be applied to Kerdi Board?

[@HomeRepairTutor]

Yes

[@terrygibbs7824]

Are you able to install this over dryall to do a tile backsplash in a kitchen?

[@ceeIoc]

You don’t need to screw the niche into the studs?

[@judo7464]

Hey Sandra McRitchie1 those razor knives have a button to release and lock the blade. They have been around for about a decade now...

[@cghrios783]

From the products you have featured in your videos for shower backing boards which one has been the best quality, workmanship, durability you have worked with? I am a bit skeptical of these products but know concert boards are antiquated. Please advise is highly appreciated. Thanks

[@fredhawkey380]

Can u fit this board to the floor? Or is it just for walls?

[@debramellecker2991]

This is specifically used for walls. They have their Dietra product for the floor.

[@coloringforkids8634]

[@Beaugus4353]

[@HomeRepairTutor]

Awesome, keep us posted. Would love to see pics

[@josephgraham1065]

I really want to use this stuff but my house has metal studs... Do they make screws for my situation?

[@davezemba9109]

If I saw a contractor standing with his boots in my new tub before putting something down first I would scream. He could have a nail or screw in the sole scratching the tub. Or just grinding the grit on the enamel.

[@dcntralizedmind2754]

You’d be surprised how much cleaner and careful you can be with the tub completely empty. Often times when you line the bottom of the tub, there’s hidden debris.

[@antrosado1503]

Hi do you need to put insulation behind the Kerdi board in between the studs on an exterior shower wall? I understand Kerdi in itself is already a vapor barrier

[@andrewblamer9202]

Always put insulation on an outside wall. Always.

[@lapointe122]

Is it the same installation for a shower

[@HomeRepairTutor]

Yes, will depend on the type of shower pan but overall very similar.

[@deaneng8540]

when cutting out the niche perhaps he should have flipped it around so the recessed side is facing him and outline his cut? That way he just has to make one cut.

[@shenoyglobal]

what is the cost difference between this kerdi and cement board

[@JesusMendez-xb8ws]

Más caro kerdi pero mas fácil

[@emadalkadri2856]

Hi, How to deal with the joint between Kerdi board and regular drywall?

[@timgleason2527]

Just use 1/2 inch drywall, do it like any other butt joint with drywall compound. (Jeff from Home Renovision tip, personally have never done it.)

[@PaulAmor]

Didn't protect the tub and didn't follow max spacing for screws in a few locations. Doesn't the latter void the warranty?

[@RobbCapeling]

awesome video Jeff!!!!

[@HomeRepairTutor]

+R Cap thanks buddy

[@rynhrst]

Great video. Quick question. Is it safe to frame out the shower niche on a load bearing wall?

[@HomeRepairTutor]

+rynhrst we wouldn't recommend cutting the studs to reframe but you could frame the existing structure. If it's an outside wall we wouldn't add a niche because there's no way to insulate behind it. The tile will ultimately crack

[@rynhrst]

Thank you for the quick response! It is an inside wall. By "frame the existing structure" I assume you mean use the existing studs for the placement of the niche?

[@HomeRepairTutor]

+rynhrst yes, and we recommend planning the tile before framing the niche. That way you won't have a wonky cut at the shower, ceiling or niche edges. What size tile?

[@HomeRepairTutor]

+rynhrst you might like our free course, it's coming out later this month. It has tips on how to build different types of showers

[@rynhrst]

12x24 tile is the plan. Will it matter that the niche wont be centered on the tub by using existing framing?

[@beckycraft4250]

with all the comments I wonder since I won't be tiling my walls I'm using barn tin or roofing tin will this be a good product for me to use?

[@lach0125]

Question. You seem to be securing the panels to the wall on either side of the seam. I've seen a number of people secure the kerdi to the wall at the seam. Which way is correct? Looks like you also save on hardware if you screw in at the seam

[@denis77777777]

In between the two is better, keeps the seams flat. If you put one on each side when you secure it and recess the screw and washer it will push the seam up. His spacing is off also, 12" minimum and he's at like 18" or more on some.

[@MyGoogleYoutube]

Why not mention wet shimming to ensure a flat surface for the Kerdi?

[@shayladuke3382]

Yeah, whats wet shimming?

[@rodralph824]

If the kerdi nitche is 1.5 inches from outside the inner nitche to outside the lip, how can you get enough bite to use a washer to secure the board and nitche because the 2x4 is 1.5 inches?

[@dickhiester3798]

Excellent production of you videos. Thank you. I have a question regarding the valve seals. I am installing body sprays in the shower I'm working on that requires a 3 inch hole in the wall board. It doesn't look like Kerdi offers a seal for this. Thoughts on how best to seal a 3" hole?

[@HomeRepairTutor]

Kerdi-Fix around the hole will help. You could also cut a piece of Kerdi-Band to fit around the rough-ins and then Kerdi-Fix the transition

[@anangrysack]

The shower valves finished trim will have a foam gasket that will cover the hole. Put a little sealant on that before installing the trim and you're good to go.

[@nicolespicer8021]

Is it okay to let the Kerdi Fix dry before applying the thin set & Kerdi band? We just applied Kerdi Fix to our tub lip this weekend and thought we should let it dry first before applying thin set over it.

[@HomeRepairTutor]

+Nicole Spicer the KERDI-FIX will seal the transition but we embed the KERDI-BAND into it and the thin-set at the same time. But you should be okay, apply ALL-SET thin-set over the KERDI-FIX and KERDI-BOARD then embed the KERDI-BAND. Hope that helps

[@davidbell7595]

If properly installed, is Kerdi Board waterproof without the use of Kerdi Membrane installed over it?

[@cafepablo]

Yes.

[@tonycarrillo1140]

What size screws did you use for the 1/2 board & do you have to use the curb or is the slant on the tray good enough for a 36x36x34 shower?

[@booradley1065]

There are some areas of conflict between plumbing code and ADA accessibility requirements. In those cases, ADA requirements win. For example, a slope of 1⁄4” to 1⁄2” per foot to the drain is required. Plumbing codes state that the threshold (or high point) in a shower must be at least 2” above the drain. The ADA mandates a maximum height of a threshold of 1⁄2” and requires at least 4’ from the entrance to the drain. Since your shower drain is not 4' from the edge a curb is required

[@joshuaskidmore999]

This guy I been working for says that kerdi board is harder to install that kerdi membrane, I been remodeling for years but just got introduced to kerdi system... IMO kerdi board would seem like the better way to keep things level & square

[@johng9562]

It's good stuff ~ but at 5 times the cost of hardi-board & redgard, the price is silly.

[@bustamantealdo]

can I put backer board behind this to strengthen it?. I have a double wide trailer and the studs are not conventional 2x4..

[@HomeRepairTutor]

good question for Schluter, we only recommend max 16” on-center dishing. You could add extra studs

[@seanmcaleavy2369]

I am confused. Schluter says that all seams of the Kerdi-board are to be joined with a bead of Kerdi-fix adhesive in addition to the application of the Kerdi band and thinset. Why is it that you eliminated step?

[@HomeRepairTutor]

What page in the Handbook says that?

[@seanmcaleavy2369]

@@HomeRepairTutor It is stated in one of the videos on the Schluter website.

[@philly258]

It appears the large wall with the niche is insulated (I assume it’s an external wall)…but the area used for the niche ends up with no insulation. Is that a concern? I was thinking about doing a smaller niche on the short wall to the left of my diverter instead…due to the same issue - with the other two walls being exterior walls. Thanks.

[@whattheschmidt]

It may just be for sound absorption and not an exterior wall. If it is though, I would get the best piece of insulation to fit in behind that board after making sure the insulation stays in place above the niche.

[@holland6648]

What can you do if you have to shim out the tub surround for the kerdi board? Where the kerdi board meets the drywall is now a difference off 2/8 of and inch

[@HomeRepairTutor]

Kerdi-Board can be set on top of the flange and that gap filled with Kerdi-Fix or you can cut away the board and leave the Kerdi membrane over hang the tub flange - are those options?

[@holland6648]

I don’t mean the difference on the tub but on the side of the wall where the kerdi board meets the drywall in this video the orange to purple board. The kerdi board sticks out 2/8 of an inch the whole height of the wall

[@JosephBlakely55]

Hi Jeff how should I transition kerdi board to an outside corner of drywall?? Should I use a corner bead and skim coat the dry wall side and just thinset the kerdi side??

[@HomeRepairTutor]

are you referring to a similar situation as that in the video (around the 17:00 mark)? We tiled the shower and used RONDEC to finish the edge. Then we skim coated the drywall side to hide the corner bead. The RONDEC serves as a great surface to help guide your drywall knife.

[@JosephBlakely55]

Home Repair Tutor bingo haha thanks your videos have given my wife and I the courage to tackle as much of our bathroom on our own as possible. Keep up the awesome work. Side note you remind me of a mix of Jeff Devlin from Stone House Revival and Ted Mosby from how I met your mother.

[@HomeRepairTutor]

Lol, that's awesome man. Glad to help any time. I met Jeff Devlin and he was a super cool guy. Really nice. Let me know if you have any other questions. I'd be happy to help.

[@JosephBlakely55]

Thought of another question, I believe my measurements for the actual shower tray are like 28" deep by like 42.25" wide to account for the depth of the curb being 4.5". Which tray would be best to buy to cut down to size the 32"x60" with the center drain or the 48"x48" with center drain?

[@JoseCruz-zn3qy]

i want to put up veneer stone up instead of tiles would it be ok

[@HomeRepairTutor]

will the stones be in a shower?

[@JoseCruz-zn3qy]

no in living room

[@JoseCruz-zn3qy]

Jeff Patterson I know I could have used Hardy back but this material is easy to work with I'm just concerned whether or not I can put veneer Stone on this product I mostly use it on unmodified thinset

[@HomeRepairTutor]

+Jose Cruz unmodified is what we use for the KERDI-BAND, we opt for Ardex X 77 for heavy tile. That said, you might want to consult with Schluter

[@JoseCruz-zn3qy]

Jeff Patterson ok thanks for your help

[@aptlogix]

where do you buy this stuff. Is it only available in one of those kits @ Lowes? - not individual boards?

[@shayladuke3382]

I saw individual boards at lowes...

[@sheadunn720]

So if your tub didn’t come with a flange cuz it’s a drop in tub, what do you do then?

[@HomeRepairTutor]

so drop in tubs are supported by wood framing. In that case, add KERDI-BOARD to the surface of the framing and add KERDI-BOARD or whatever material you're using to the top of that. You're free to choose any waterproofing but if you go with KERDI-BOARD stick with the Schluter products for the wall if you think it needs waterproofed. Same rule applies for wedi, Laticrete, etc...stick with one system if possible to retain max warranty

[@NativeNYerChicHK]

Schluter now says it’s acceptable to build up studs with mortar for leveling Kerdi-Board, not their actual recommendation but acceptable so that it doesn’t void their warranty to do so.

[@HomeRepairTutor]

yes, wet shimming is an option. Our Schluter rep brought up one concern though. If over time the mortar dries out that could lead to problems. So we opt for furring studs with plywood.

[@NativeNYerChicHK]

Home Repair Tutor Yeah, I never considered that it could (or rather will) eventually dry up and crumble off, thus voiding that leveling. Shims or planing are definitely better alternatives for long term durability!! Thanks for that!!!

[@mikez4132]

@@NativeNYerChicHK the person I talked to said that wet shimming is fine because the mortar cant be displaced unless there is significant movement between the studs and the wall panels. Same as under the tile.

[@julianomadelinebrunorio458]

why not make a 3/4 notch on the bottom of board and lower the board closer to the tube eliminating chance to leaking ?

[@HomeRepairTutor]

+Juliano & Madeline Brunório that is certainly an option, we'd still use KERDI-FIX against the tub flange.

[@dionjohnson3164]

[@MajorTendonitis]

Guys I bought a 3" hole saw to cut the hole for my Delta mixing valve . Kerdi has a flange , but I'm not going to bother using it considering I am going to have a Delta diverter valve above the mixing valve , and the flange would be to large to cover with the diverter bezel . The sad part is , the diverter sits inside the Kerdi board , not extended out like the Delta mixing valve . Sad design imo by Delta . I'm trying to find a socket to fit the bonnet , as it's not very accessible. No socket that big available in our town of course

[@HomeRepairTutor]

+MajorTendonitis it sounds like you had some issues with the install but it's okay now?

[@MajorTendonitis]

+Home Repair Tutor I haven't installed my 1/2" Kerdi board on the alcove side which has the valves yet . Have been studying and procrastinating to much to attempt it yet . I have a spare piece of Kerdi to do a test with , so I'll experiment with that first . Apparently there's some trailer hitch socket that is the same size as a Delta bonnet , 1-7/8" . But I'm not positive if the diameter of this socket is under 3" . May have to go to lordco and see if they have one

[@MajorTendonitis]

+MajorTendonitis Btw , I sure love working with Kerdi board . People say it's 2.5 times more expensive to use than backer board . Not sure what there last grade was when they quit school , as I've found Kerdi to be closer too 15 times more expensive . It's $106 for a 4x8 sheet here at are carpet store , or $7 a sheet for backer board . The taxes on the Kerdi board were more than I would have payed for backer board

[@Stevesbe]

That metal corner bead will certainly rust being right next to the shower

[@HomeRepairTutor]

It shouldn't but if you're concerned then apply either KERDI-BAND or KERDI-FIX over it

[@brookemcquale5096]

use plastic corner bead instead, or Schluter products (aluminum).

[@_multiverse_]

Kerdi board sells for 150$ a sheet in canada, I fail to see the advantage of using this vs drywall and and kerdi membrane other than a Slight time savings.

[@HomeRepairTutor]

Here in the states a 1/2” x 48” x 96” board is $120 and a 1/2” x 48” x 32” board is $40. Sure, it’s more expensive than drywall. But you don’t have to worry about paper. And you can build custom niches, curbs, and benches with the leftover pieces of KERDI-BOARD. I’m not paid my Schluter or any waterproofing company, just like their products

[@mfresh422]

Great video but try being a little more careful with the tub, maybe try covering it up so you don’t damage it 👍🏻

[@HomeRepairTutor]

Thanks Manny, you’re correct. We should have used protection

[@LokiX76]

I’m sorry if this has already been asked. So no insulation behind the niche? Our shower sits on 2 exterior walls and I was planning on a niche on one of them. I wasn’t sure what to do about the insulation. I assumed just squash it with the niche.

[@HomeRepairTutor]

We don’t recommend niches on exterior walls, primarily because there’s no good way to insulate behind the niche. And that can make for a cold shower and cracked grout joints. Can you put two niches in the one inside wall?

[@LokiX76]

Thanks for the speedy reply. That's what I though. That it would make the shower cold. And not really. The one inside wall is fairly narrow and has the plumbing. I could maybe put a very tall narrow niche. The other wall is glass and then there the door. It's an odd shaped corner.

I was excited, until I saw the price... Concrete board for me :)

[@HomeRepairTutor]

Keep in mind you should waterproof the cement board, that adds a bit to the final price. One thing is for sure, KERDI is easier to cut and handle than cement. Always good to have options :)

[@ryanbruneau1197]

Dude it's WATERPROOF. You will save money in the long run by not replacing rotted structure

[@7439norma]

how much is it

[@ryanbruneau1197]

David Ishmael They sell it at Lowes

[@booradley1065]

@@HomeRepairTutor Sorry, just use felt sheathing paper under the cement board. It is not required to waterproof it just keep it 1/2 above the tub rim. Tile sticks better to unwaterproofed board and doesn't slide around. This stuff looks like you could easily punch a hole through it or damage it. No way I would put in my house. They are trying to convince everyone that the substrate surface must be waterproofed.

Nice video Very helpful, but what’s up with the classic background porn music?

[@cooldog60]

The worst think that can happen in your shower is if you slip and fall on a bar of soap.

[@HomeRepairTutor]

+cooldog60 yes, that would be bad - no argument here :/

[@ericdarbyshire7591]

Wrong. You going to leave all those screw holes unfinished? Every screw hole is a perforation of the Kerdi Board

[@stone2125]

What's with the 70s porno music? I thought we were learning how to install material? 🤔

[@ewarda100]

I am sorry guys but this material it's worst than hardybacker or wonder board. I understand this crap it's only for homeowners or rookies I'm a professional tile installer I float my walls and floor with cement. This video it's really sad.

[@HomeRepairTutor]

+jesus trujillo totally disagree, many installers use it. The benefits are numerous and while floating is still good, KERDI comes with a 10 year warranty. That's good for the homeowner. Plus, not all 'pros' are created equal. Some are great at floating and some are hacks that disappear after the job is done and nowhere to be found when their job fails.

[@trianaramirez]

Home Repair Tutor true. In the end water destroys all though. Well be doing demo in a bathroom here in dallas in the highland park area on a bathroom that they had told them "guaranteed 10 years" but its been less than 3.

[@jesustrujillotileinstaller6133]

Will Pelton // I really respect your opinion but I know some glass door guys when they install really heavy frameless doors they really care much about how strong it's behind the tile when they screw into the wall they always try to do it in the studs. But even that the tiles cracked sometimes not all the time. But most of them they love when the walls are flooded with cement they don't need to look for studs automatically they walls are superstrong.

[@jesustrujillotileinstaller6133]

Will Pelton. If you make a hole on the wall on kurdy. And you make another hole on a cement wall. If you install on both walls plastic anchors with screws. the kurdy can be strong as cement wall ? Can kurdy by itself can hold the same weigh as cement walls ??

[@warlok9]

MOST Tile guys are a special breed. They believe that there is only one correct way to do an install... THEIR WAY

[@fallingspark2258]

Could aqua defense work on the seams/joints rather than mortaring with the kerdi band? I'm going to be going over the whole wall with an adhesive shower wall panel by Swan (caulking the corner seams of course) and am using Kerdi as a light weight structural backer for this panel. Thanks! (added note for info, I am using a sloping shower pan by Swan as well)
