Did I Mess Up Big Time?

I applied a lot of Kerdi Fix and then let it dry before I realized that I should have applied the Kerdi Band over the Kerdi Fix while the Kerdi Fix was still wet.

Do I just use unmodified thinset over this?

If not, should I get another couple of tubes of Kerdi Fix and apply fresh Kerdi Fix over the dried Kerdi Fix and apply the Kerdi Band to the wet Kerdi Fix?

I wanted to ask before I make anymore mistakes.

Thanks for the help everyone!

Welcome, Dustin.

You're got a problem there.

If you'll read Schluter's instructions for waterproofing that area (available online), you'll find they want you to use Kerdi Fix to bond the KerdiBand to the tub's tiling flange, but to use thinset mortar to bond the KerdiBand to the Kerdi walls.

I can't tell just what you have there because of the material smeared in that area. Don't know if both the gray and the white materials are Kerdi Fix. Can't tell if your Kerdiboard laps over the tiling flange or stops above it. Perhaps you can fill in those blanks and we can start from there.

My opinion; worth price charged.

Yesir,

That is all Kerdi Fix both the grey and the white there is not any thinset or other product applied to the board. The Kerdi board is sitting on top of each tub flange all the way around.

Might give you peace of mind to cut out and replace the bottom 10” or so with fresh k-board.

However - I had a shower where I had Kerdi-fixed ledger board holes days before banding the shower pan-to-wall joint. Similar situation to yours, what do use over dried Kerdi Fix. Schluter rep had told me to install the pan-to-wall banding with more Kerdi Fix (and only Kerdi Fix, no thinset), notched out with small v-notch trowel to ensure continuous coverage. I followed that advice and shower pan passed a 24 hour flood test.

Thanks for the reply Lou!

What is pan to wall banding? The Schluter Kerdi Band?

Edit: Yeah that is what you meant now that I am reading it correctly. It seems ill need to use Kerdi fix for the entire width of the Kerdi Band but thats how I'll proceed.

Yes. The 5” wide band that laps from the shower floor Kerdi onto the Kerdi board walls.

Keep in mind that my dried Kerdi Fix was just to cover several screw holes. So each spot of Kerdi Fix was maybe 3” in diameter or so.

I *had* confirmed with a Schluter tech support that fresh Kerdi Fix would stick to cured K-Fix. They were surprised by the question, seemed like the first time they were asked it, but after checking they told me it would.

Hmm maybe I should just cut out the 10'' and replace it. I may as well.

To be honest, that’s what I’d suggest. It’s the preferable route.

Well thank you very much Lou and CX that is what I'll do. What should I do about the Kerdi Fix stuck to the tub flange now?

I'd at least try to scrape it off, Dustin, to keep from having bump there come time for tile. If that's not an issue, just bond the KerdiBand over it with more Kerdi Fix. The mechanical overlap there is what you're really counting on, anyway.

My opinion; worth price charged.

Dustin, just to make sure, your corners where the board meets the board will need kerdi band and thinset. It looks like you put some of the white kerdi fix there too, and as far as I know schluter doesn't allow that as a valid way to waterproof corners. Hopefully there isn't too much buildup either or the kerdi band may make it even worse.

Cliff no worries, I was just filling in some minor gaps with excess Kerdi fix I had. I absolutely am using Kerdi band with Kerdi All Set to cover all joints.

This is what it should look like. The blue tape is only to protect the exposed part of the tub - it does not go under the Kerdifix and was removed after the band was applied and the Kerdifix was still wet.

Kerdi Fix Scraped Off

do you think this is clean enough to apply fresh Kerdi Fix to?


Edit: My bathtub is not on the ceiling I assure you. Sorry for it being upside down I'm not sure what happened
