I've heard good things about the Schluter system. It is supposedly quite user-friendly. But the price, for a plastic product, is far far far too high. Unreasonably high. Bring the price down and maybe I'd be interested.

[@liztaylor85139]

I'm using this same system but I'm also using a Schluter preslopped shower pan. My wood subfloor is a little out of wack/uneven. I called Schluter and they told me NOT to use self leveler but to use cement board on the shower floor to even it out before installing the pan. I would install the cement board as if I were tiling the floor. So I would burn the thinset in and then trowel to place the cement board down. Then trowel the top of the cement board to place my foam pan. But Schluter has an excellent tech team you can call at any time if you don't want to guess at things.

I'll save a ton of money, but I want to make sure I do it right the first time. Quality work is important to me.

[@AnthonyClark177]

Thanks for this very helpful clip. I read some experts who strongly suggest that we don’t put waterproof membranes between cement board and the tiles; just apply thin set. So, I was wondering if the direct application of the tiles on the cement board is another approach for all tiles installation or an approach to deal only with ceiling tiles. Thanks 😊

[@HomeRepairTutor]

I would always use some type of waterproofing on cement board. Here’s why, showers produce water and vapor. And it’s the vapor that can easily create mold inside shower walls. KERDI membrane or liquid membranes reduce the flow of vapor into the stud walls. So I use waterproofing on the walls for that reason

[@summertime688]

Do you have a tutorial for installing the shower niche in the backer board? (I see one using all Kerri board but was hoping to see the difference.)

[@thecelticforge]

One set of instructions I read, stated to leave a 1/4" gap between the cement board and the studs. Not so?

[@dido1803]

Great presentation!! How is cement board compare to sheetrock, for sound proofing?

[@HomeRepairTutor]

they’re about the same, I’d add Rockwool inside walls to cut down on noise

[@Crewrenovations]

Do you recommend water proofing with thinset the corners & mesh tape plus red guard when using cement board?

[@liztaylor85139]

Waterproofing with any type of red guard voids the Schluter warranty. But I'm installing the same way he is and once I get the Kerdi up and my foam Kerdi shower pan down... I'm going over the entire shower with Aquadefense! All these companies have great technical call lines with great answers as well FYI.

[@sunshinecompany1]

Do I have to use the membrane? Isn't it cheaper and easier to use waterproofing and paint it on?

[@DavidKlausa]

Yes, Redgard works fine and is much cheaper.

[@MR713JOSE]

Yeah screw, it I'm going ahead with drywall screws

[@davegordon6943]

I always add horizontal blocking between studs were the two sheets will meet and the bottom when using Duroc. It's very breakable and brittle and most of the time it's already lost its structural integrity before you even install it. Even though technically it doesn't add any structural integrity according to building inspectors. But you know what I mean, it gets all floppy. Don't get me wrong I think it's still a good product but needs reinforcement. It won't wick like Hardi and it's not foam. (My overkilling self won't let me use foam). When installed correctly with taping, mudding and waterproofing I think it's a better overall system. But I certainly don't claim to know everything just my opinion.

[@liztaylor85139]

I'm a first-time installer of a system like this. Should he have taped the seams on the Durrock? Before floating for the Kerdi membrane?

[@davegordon6943]

@@liztaylor85139 when I use durock I use mesh tape, thinset and then redgaurd. I don't like the kerdi or shluter stuff. But if using it, they make a 6 inch banding fabric to use in place of the mesh tape, thinset and redgaurd. But yeah I'd do all seems and corners.

[@0zen551]

What about cement boards for tub surrounds? Do they also need a .25 inch gap?

[@HomeRepairTutor]

At the tub deck, yes

[@mavo_hiphop]

Can you do this and then install direct to stud bathtub walls? Or is this only for tile?

[@DTWCT]

Is that schluter necessary or can you just apply thinset right to the cement board and tile away

[@HomeRepairTutor]

Cement board is water resistant. That means it isn’t waterproof and vapor will go through it. Thus, I recommend waterproofing it with KERDI or a liquid membrane

[@RK-ys7xm]

Hi Jeff, love all your videos. You are a fantastic presenter! Does that thin set wick water the same way the Schluter banding wicks water when using thinset to adhere it? I was watching the Tile Coach's videos and that seemed to be a big issue. Can you please share your thoughts on that? Do you have a thin set that you recommend to prevent that wicking? Thank you.

[@HomeRepairTutor]

Thank you and I'd be happy to address those concerns. Also, I'm not paid by Schluter or any waterproofing company. I just like Schluter products because they work and the technical support is the best - I do custom installations and lean on them a lot!! Here's how Schluter's system works: thin-set bonds to the fleece on the shower tray and to the KERDI-BAND. The thin-set has to be mixed to the correct consistency and applied with the appropriate trowel. For example, Schluter ALL-SET has specific directions for how much water to use for membranes like KERDI or KERDI-BAND. Use that those mixing directions. Then apply the thin-set with the KERDI trowel held at a 45-degree angle, this maximizes the trowel notch. Immediately embed the KERDI-BAND or KERDI into the substrate and express just enough thin-set from the banding or KERDI to make it flat. Over time, thin-set crystals will grow and anchor into both sides of the fleece, e.g. on the shower tray and KERDI-BAND. Those crystals will physically prevent water molecules from penetrating the bond. I cannot vouch for the type of thin-set Tile Coach used or how he mixed it or his water ratio. Keep in mind, his experiment is a N = 1. Meaning, it's one sample. In real world experimentations (my background is chemistry) a sample size of 1 is not a meaningful number. I'm not trying to be disrespectful, just objective. If you more questions I'd be happy to answer them here or via email at [e-mail]

[@rosadiaz9355]

Can the cement board go over brick wall?

[@halinamann9535]

May i ask how is it 100% waterproof, if the thin set that was used as adhesive absorbes water?

[@HomeRepairTutor]

It’s only waterproof if you use a liquid or sheet membrane over the cement board. Here’s a video showing how to use KERDI membrane kzbin.info/www/bejne/f3WmmKxsiN55oLssi=l32pu1EwHvLumBsH

[@sunshinecompany1]

Can I put boards directly over lathe and plaster?

[@philliphill4901]

How much gap can you get away with before trying to shim the wall board? I running about a 3/16 gap between stud face and the cement board and what is the preferred method of shimming

[@preludesc]

What’s the decision process for doing this versus Kerdi-board?

[@HomeRepairTutor]

I would have used KERDI-BOARD but it wasn’t in stock at the time, that said, cement board can be more affordable so it’s a good option if you cannot find KERDI-BOARD

[@liztaylor85139]

I personally could not afford the Kerdi-board so I went with Durrock using the Kerdi membrane that came with my foam Schulter shower pan.

[@vvsmixing]

what exactly is the point of cement board if the waterproofing is done by the kerdi membrane which is also protected by the finish

[@paulmaxwell8851]

The cement board gives you a solid, immovable surface. The Kerdi foamboard is flimsy in comparison.

[@catsmeow5566]

I'm doing a surround over a tub. Do I need the 1/8" expansion gap between the bottom and top boards? I'm not doing tile, I'm using a glue up surround. Some of my studs are greater than 16" apart but I have a chunk of plywood horizontally that will add extra support in the middle a bit. Some studs are closer than 16". Hmm... So the cut off edge is put down against the previous board instead of having it at the top? That's good to know.

My wonderful contractor has about 5 inches of cement board open past the shower tile. How should it be prepped in order to paint over?

[@HomeRepairTutor]

That’s no problem, finish the tile then Kerdi-Band or mesh tape the seam. Use setting type joint compound to feather the transition, eg 2-3 passes with 6” then 10” then 12” knives, sanding after each coat. Then prime and paint

I called Schluter and they said it was perfectly fine. I'm a DIYer and could not afford the Kerdi walls so I went with Kerdi peslopped pan and Durrock for walls. They did tell me to use the SMOOTH side out on the cement board because the small points on the rough side have a chance of making cuts/holes in the Kerdi membrane when you install it on the walls.

[@George-pz6zl]

​@liztaylor85139 did you install your cement board above the schluter pan or down to the subfloor?

[@dtaposse2832]

Do I need a gap between the first board and the tub?

[@paulmaxwell8851]

Most authorities say you need 1/4 inch between the cement board and the rim of the tub or shower. Others say don't come down over the flange at all. This is a very contentious issue.

[@forrealtyler]

Kerdiband and the corners?

[@HomeRepairTutor]

So yes, I KERDI-BAND the transition between the pan and KERDI on the cement board. But, that’s after installing the inside corners
