[@kevinmclauchlan5904]

Thanks for all the explicit instruction. I'm at the stage of having all the Kerdi-board installed and the majority of screw/washers waterproofed with 2-in-1. About to thinset (Kerabond T) the Kerdi band on the seams. (BTW I asked you to clarify a remark you made in a response to Josh .... like 9 months ago, but I saw it just now and elaborated my confusion about Kerdi-band overlapping bottom of Kerdi-board and the flange it abuts... if you would be so kind, after you set me straight on this current question, that I'm about to get to) Anyway, I will have my 12-inch-by-24-inch porcelain tiles overlapping the bottom of the Kerdi board and hiding the tub/shower-pan flange by about an inch. So, should I shove some 2-in-1 into the bottom of the gap where the tiles will almost touch the tub/shower pan deck? AND, if I do that, should I leave some weeping hole gaps in the bead of 2-in-1? This was advised by another DIY video guy (ahem! coff-coff-floor elf coff-coff... not mentioning any names). He sez the Kerdi or other waterproofing behind the tiles is definitely water-proof, but the tile layer (notably grout) won't be totally waterproof, so any moisture that gets through and is trapped back there has an opportunity to exit via the weep holes. Sounds fishy when you have all that thinset in there, but I thought I'd ask. Thanks for your excellent teaching videos. Contractors everywhere are going to lose a lot of business correcting home-owner mistakes that might not happen, now. :-)

[@HomeRenoVisionDIY]

I suggest using kerdi band to the tub and then tile. trim off the excess after the tile is installed. cheers!

Love your channel! Wondering what you do around the lip of the tub where the kerdi sits. I have my board installed but get differing opinion on how to proceed from here. One channel recommended using unmodified cement and kerdi band to create an overlap across the base of the kerdi board and the lip of the tub. Any thoughts on this?

I love this system! Think I can do this with only a plumber, even as a single gal. I know this is an old video, but I want to ask: my walls seem to have no sign of mold at all.

There's just a bit of mildew behind the tar paper and I wonder what to replace the tar paper with, especially on the two exterior walls (brick on frame construction).

Hey Jeff, is there anything special you have to do at the outside border where the Kerdi board meets the drywall of the bathroom wall? Great video thanks a lot.

[@thomasnorthcastle4130]

I always run my Kerdi flush with my drywall. I make my Kerdi short at least by 2”. I tape the joint with Kerdi Band from the ceiling down to the floor. The reason I do this is so that the tile actually starts on the Kerdi banded drywall and bridges onto the Kerdi Board. I also use Schluter profile strips on the edge of the tile.

Schluter products might be a tad pricey, but done right; they are made to last & rather spend little extra at beginning, then having to repair or redo the shower in next 5-7 yrs! Really like the Kerdi products & the ease of use(once ya know what doin'), just wish was easier to buy the schluter no sag easy bond cement & "caulking" at the local box stores. One would think, they sell the other products, so why not that stuff.....??

First off I would like to say thanks for all your videos, I've learned so much from watching them. I am in the middle of a bathroom renovation in which I am going to use the Kerdi board. I have read several articles in forums online that state that having a vapor barrier behind this waterproof system as it can create a "moisture sandwich" and is not recommended, if possible could you please advise me of the pros or cons to having the vapor barrier as I was unable to find the answer on the companies website.

@Kizz, just to clarify your concerns, correct me if I'm wrong here, but in order for Kerdi Board to turn a "small fire into a life taking inferno', wouldn't the whole bathroom have to be on fire and either the tiles which are impervious to flame have fallen off to allow access to the Kerdi, or the walls have burned down from the other rooms to reach the Kerdi? In either scenario, I don't see how a 'small fire' is going to even reach the Kerdi product. Help me to understand your thinking on this.

Once the kerdi board is in place do you just glue the tiles on? My tub/shower has plastic tiles that fell off and a hole at the faucet. I'm trying to get down to the studs to put up the kerdi board then re attach the tiles.

Hi, can you explain what to do with the gap from the ceiling to the call? You put it in lose to have it fit better, but I'm unsure of the next step to fill it. Did you use the caulk there?

[@JuliaFerry]

I have some overhang from the .25" Kerdi board and my tub tile flang. Can I run Kerdi board over the tub flange, leaving a small gap to seal with Kerdi Fix to the tub? so in other words the studs and tile flang on 2 of the tub sides are pretty close, closer than the thickness of the Kerdi board. Or do I need to shave down my stud walls so the Kerdiboard rests above the tub tile overlay and it's flush between the two?

[@chrisd4432]

My only question is obviously the Kerdi board is thicker than the mounting flange for the tub so where the bottom of the Kerdi board meets the flange and you sealed it wouldn't the Kerdi board stick out a good bit and make that seam an issue? Either that or I assume you have a shim of some kind behind the screws for the tub mount? Couldn't you also run the Kerdi board all the way to the floor before installing the tub and then seal that seam? Thanks

Wouldn't have to unless you're doing a steam shower. But you could use Kerdi membrane for the ceiling if the bathroom tends to get steamy whilst using the shower. Use Kerdi band between it and the Kerdi board just like you would for the seams and washers with screws used to install the Kerdi board to the wall studs.

Great video, thanks! Question: I have the Schluter shower kit, but bought the Laticrete Hydra Ban boards to use for the walls. They had them at my tile place, and it was a lot cheaper than the Kerdi board at Floor and Decor. Can I use the Schluter fasteners (with washers), and the Kerdi band waterproofing technique (with unmodified thinset) on the Hydra Ban board just the same? I would think the material is the same (polyethylene).

[@HomeRenoVisionDIY]

sounds plausible, but why are you experimenting on your house. You will have no warranty if you blend the systems.

Hi Jeff, You do fantastic videos. I am installing Schluter for the first time. I live in Florida and want to place the Schluter board on an exterior concrete block wall that is built out with 5/8" furring strips. A vapor barrier is not needed here. How do I attach to the furring strips with 1/2" Schluter board. It only creates a thickness of 1 1/8" and it called for 1 5/8" screws, plus some pull in to cover them with thinset. If I build out the furring it will not match the drywall thickness on the adjoining wall that is only separated by a glass shower wall. This block wall also has the 1/2" copper supply. So bottomline, I am not sure what to do to install the Schluter board on this block wall? The other two shower walls are framed, so no concerns with them.

The valve my client selected does NOT fit into the provided 4 1/2” guard. How do I seal the opening before putting on the trim cover?? It’s my first time with schluter. Thanks

[@HomeRenoVisionDIY]

Hi Robert. The reason that guard does not fit is simple. Most quality valve companies have a face plate that is snapped into place against another fixed plate that is screwed to the valve and comes with a gasket that sits against the tile to keep the water out. In this situation the schluter guard is not necessary! The guard you are referring to is designed to deflect water that gets behind the face plate of the cheap valves covers that have poorly designed gaskets and /or face plate screws like moen and delta.
