Mix ALL-SET per the directions, this is SUPER important to get the right consistency and pot life for the mortar. We used 6-1/2 quarts of water for one bag of mortar. And mixed the mortar for 5 minutes, allowed it to slake for 10 minutes, and mixed it for another 3 minutes after slaking.
It helps to place a plumb line on the drywall to indicate where the KERDI membrane should stop. Take a damp sponge and wipe down the drywall to remove any dust and to prevent the thin-set mortar from setting up too quickly. Then use a KERDI trowel to work the mortar into the drywall surface. Directionally trowel ALL-SET on the wall to help remove air gaps and collapse all the ridges in the mortar.
Compress KERDI membrane into the walls, going from the ceiling to the floor. Remove air gaps and flatten KERDI using either the KERDI trowel or 6 inch drywall knife. Overlap all KERDI membrane by 2 inches.

thx great video
thanks!! Can you do this on drywall that is already painted or smooth plastered (smooth paint in a bathroom)?
My bathroom is a 5’ x 8’, but I’ll only extend the Kerdi out about 28”. And the original wall is a wooden wall covered by Sheetrock .
We will open the wall to update the plumbing and reinstall wood and Sheetrock. And the wall has some wallpaper that needs to be preserved
Out past the borders. So Im thinking that the sheeting might be the best option?
@10:54 there is a schluter squirrel on the first wall he covered lol
Great job. Just a lil messy 😁
I used Kerdi band on my seams but I think you get less build up by overlapping the Kerdi membrane like Steve did. Great video.
Yes, it’s a bit faster, too.
The Kerdi band is thinner. Overlapping is thicker.
@@HomeRepairTutor can you also overlap wall membrane over the shower pan in lieu of Kerdi band?
I just use the schluter base and drain kit , it is easier to Red guard the walls and curb with no overlap in the corners.
Do you need to do anything to the drywall mud before going over it with the thinset?
Were you using regular drywall? I didn't see any green board?
I've got an important question.
I'm currently doing a bathroom restoration. "Does the membrane attach to previously painted surfaces (in my, case semi-gloss paint?)
Should I prime it with KILLz prior to using the membrane?
''this corner of the niche is gonna be very important because its gonna get hit with the most water'' proceed to do a hack job with the made up corners lol, i can't
i noticed some of the dry wall has been mudded and other part are not, what gives. should I or shouldn't I tape and mud all the screw areas and gaps?
Did you prime over the join compound like Schluter recommends? If not, why not?
I used 1/4x3/16 trowel and unmodified thinset. The membrane got so uneven. What to do? Is my thinset too thick? Did i apply too much?
Can this system be installed over painted drywall ?
Why not install the membrane horizontally starting at the bottom over lapping two inches? Seems like it would seal better and be easier to do.
So, can I use regular or green drywall? No cement board needed?
Can I Kerdi over spackled un-primed drywall?
That's the slappy job a have ever seen.
While putting on the membrane. I was pushing the air gap out but I did it so much that the fiber on the membrane started to get fuzzy. Is that OK?
What happened to the tip of your left ring finger?
is drywall then Kerdi membrane better thank Kerdi board? or do you recommend just using Kerdi board if budget allows
Great set of Videos very helpful Can the Kerdi membrane be applied to a painted concrete wall ? Thanks!!
KERDI can be applied over drywall that has latex paint. Schluter recommends unmodified thin-set or ALL-SET to bond KERDI to painted drywall. Also, make sure the drywall is in good shape and the latex paint is fully bonded to the drywall.
Oops, typed up that response a little too fast. Is the concrete wall flat?
@@HomeRepairTutor Hi the wall is flat.. thanks !
@@brucewalker8629 to be sure, send me an email with some pictures of the wall and the shower surround. My email address is jeff@homerepairtutor.com
I'm in the process of redoing one of my bathrooms and have all the Kerdi membrane up and it's pretty secure to the drywall. However, I haven't been able to tile yet, so I've had to use the shower in this current state. I've noticed that the Kerdi membrane is always wet to the touch like it's absorbing water and I can see a definite color change. I also have one of the niches and it also gets darker as if the water is being absorbed as well. I also have noticed capillary action where I have seams covered with Kerdi band. I used unmodified thinset, applied Kerdi band in the corners, bottom of the tub surround, and maintained the required overlap. I'm worried that something went wrong or am I just being paranoid? Since, I planned on starting the tile in the next few days.
If you're going to use the shower in the future before you tile. Install plastic on the walls. You do not want to go around Protocol with this product.
What are the reasons for using board or drywall and membrane
You voiceovered that you need to mix at the right rpm's. What speed- fast, slow, medium?
Basic Qs. 1)Does Kerdi board install necessarily need a cement backer board or a drywall? Thought I saw you installing it somewhere without either one. 2) Attaching tile to Kerdi board after the prep - do I use the same concept as installing tile to cement board in terms of trowel, thinset consistency, coverage etc? Of course with the unmodified thinset.
Kerdi needs to be applied over drywall or cement board. Kerdi-Board is attached directly to wood or metals studs that are 16" on-center. Tile can be set directly to Kerdi or Kerdi-Board using unmodified thin-set mortar or Schluter's ALL-SET mortar, the latter is very good.
@@HomeRepairTutor Got it. My bad, mixed up Kerdi and Kerdi Board. Your channel rocks.
@@clearlybehind thank you, hopefully the videos are helping out
@@HomeRepairTutor More than you can imagine. Missed Thanking you for taking the time.
thanks!! Can you do this on drywall that is already painted or smooth plastered (smooth paint in a bathroom)?
Which product is the most economical, the Kerdi sheeting or the kerdi board?
I still had issues with the thinset grabbing onto the fleece. It doesn’t look like a difficult process but I find it doesn’t consistently hold onto the fleece. It will look all good but when it drys I find spots where it didn’t hold and leaves air gaps. I’m not sure why I have so much trouble with this.
I feel your pain. I’m doing one right now and having a hard time getting a good bond.
Make sure you have the proper thinset
@@brendanokeefemusic- what kind of thinset need it ?
What mixer do you use?
We're currently using Milwaukee's cordless mud mixer, but a different one in this video
Why are they using drywall instead of backer board?
Hi I have questions this is more work than red guard and why we have to this Kerdi system
it's about the same after installing cement board and filling in the seams with alkali resistant tape then RedGarding...well, after typing that, Schluter is faster because both systems needs to be flood tested but RedGard needs multiple coats
Can the wall of the shower be built with cement board material rather than plain sheet rock? just for extra water proof potectionj
yes, but drywall works a little better because it's flat. There is no need to finish the drywall with joint compound
@@HomeRepairTutor So, you're saying you would have to compound the seams if you use cement board?
@@evertith if water penetrates the kerdi system then yes it would be greater protection. But you would have to waterproof the seams for that additional protection to benefit you. The additional seam protection behind the kerdi would cause a slight bump out, especially in the corners.
Should you do the wall first? I was taught to do the wall first?
My bad , I meant finish the pan first?
Is there a reason why you couldn't install the Kerdi membrane horizontally from the bottom up so that your overlaps are always shedding the water on top of the piece below? I have heard of some concerns that although the Kerdi is waterproof the thin-set mortar is not and in some instances the thin-set can wick water to somewhere you don't want it. Just seems like horizontal overlaps would be potentially better.
i like your logic isn't that why house roof shingles and siding run horizontally. i can imagine it would be more difficult to install by your self
You can do it horizontally, a lot of guys do just for that reason, just might have to work two corners at a time. My wonder is if you can overlap the shower pan and cut down on Kerdi band.
@@zackfielder That seems like a great method and you wouldn't need Kerdi-band.
@@shaner5252 that’s what I figured, it’s the same thing and eliminates a lap, just do corners first? I assume they’d seal to drywall fine with the Allset just like the membrane anyways.
plumb line not level line
Do you have to mix a whole bag of allset just to lay the kerdi membrane on the wall? Did you end up using the whole bucket? or just throw away the rest? That stuff is expensive!
Haha, I was wondering the same 😆. I was hoping to sneak a peak at how much was left in his bucket at the end.
I'm getting ready to put some up in the next few weeks, I think I only need about 3/4 of the bag at most for the kerdi. I think I might mix about that and then gauge towards the end if I need to mix a bit more. 🤔
What if my kerdi is not completely smooth. Not air pockets. Just some slight high spots here and there where there is slightly more thinset under the membrane? Do I need to start from scratch? It appears to be fully embedded with great coverage.
Great question, it sounds like just a thin-set problem behind the Kerdi. In that case, you could grind down the back of the tile to let it sit flat against the wall. The Montolit STL diamond cup wheel is fantastic, it's not cheap but well worth the money if you have several spots like that. Here's a tutorial we did on that blade that shows how it works

Home Repair Tutor thanks! Am I going to have to address it though? Or is it going to be a horrendous tile install if i don’t? My backer board was perfectly flat lol. It’s not significant at all when i run a 5 foot level across but it’s not perfectly flat anymore. Maybe a 1/16 here and an 1/8 there.
That's not terrible, 1/16" can be adjusted with thin-set mortar but it does depend on the size of the tile. What kind of tile are you setting on the wall?
Home Repair Tutor I’m using LFT 12x24. It’s not noticeable with eye. Just when you run over it with your palm you feel a slight wave to. Like a flat wavy surface of that’s a thing haha. Maybe I’m just too much of a perfectionist. I will be using T lock leveling system...still need to purchase that.
You should be okay, back buttering the tile and using the correct trowel will give you enough thin-set to position the tile flat on the Kerdi. If you need help with T-Lock let me know, we have it in our store and ship for free in the continental US. I'd be happy to help in any way, here's a link to our store shop.bathroomrepairtutor.com/collections/tile-leveling-systems
Same 1/8”trowl for putting down dietra?
Schluter makes a Kerdi trowel
Home Repair Tutor just picked it up today thank you !
That's like a 10 inch overlap bro
This membrane looks like a nightmare to install. Why would anyone use the membrane over the kerdi board? Thanks for the videos.
Drywall + Membrane is cheaper than Kerdi Board.
Lot less work if you use the board just have seams a screws to cover not so much labor
Looks horrendously laborious, especially if you're the drywall installer as well. Why not use Kerdi board instead?
I get the opinion that this guy fells trees using only a utility knife.
I don't want to be rude, but if the walls were done with Wedi, it would have been done before he even started putting up the schluter and he could have started tiling by part 2. Still don't trust the bases though.
When is Part 3 coming? [hands on hips tapping foot] :-/
Part 3 is due this Saturday. Sorry, 30 minute videos take awhile to edit and we had to do three of them for this series but it’ll be good
The first 2 are absolutely the BEST video's I've seen - better than the Schulter kit DVD!
Thank you, this shower was a bit different than the ones Schluter did
Scott, Video 3 just came out yesterday 👍🏻
There is no videos on Kerri membrane over hardi backer.
This is because it sucks ass.
It will not stick to hardi backer
The whe schluter bs is wrong.
Its an expensive alternative to what we all have been doing for years
I cringe every time I hear you say nitch!
Man, this guy does sloppy work. Sloppy sloppy. You MUST you an outside corner if you cut through on that niche! Your'e just asking for trouble. Also, messy cuts (I know, "but you won't see them!". But your quality of workmanship, even when it's not seen, is important. Sheesh man, no offense, but I can't believe you charge people to do this kind of work. You're the reason subs get such a bad rap. Have some pride.
Hello! Very interesting tutorial, just I have one concern, would it be better if Drywall will be primed befor use any mud ? Let me know. Thanks.
No priming necessary, that could be a bond breaker for thin-set mortar
@@HomeRepairTutor Nonsense.
