Can you use only this band for the backing on a kitchen counter backsplash. I don’t need as much...

Asked by Mike February 19, 2021
3
Answers

No reason why not. If you can get the Kerdi to come down the wall and under the counter tiles that would provide best assurance of getting no water seeping under the backsplash. If this isn't possible, caulk under the backsplash tile. Kerdi should be embedded in thinset on its back and front.

can you use this with redgard

No, we do not suggest use of RedGard in a complete Schluter Shower System. Please contact Schluter Systems' Customer Support line at 1-800-472-4588 to discuss in greater detail.

No, the KERDI membrane is installed using non-modified thin set.

I recommend installation with a lipped edge up the outside joints, and overlap membrane at any seams you needed. See YouTube videos that go into this detail very nicely.

Can this be used to build up an area so thinner pebble tile can be added at the same height as the field tile.

Asked by Diymom July 26, 2019
3
Answers

That's an interesting question and best answered by understanding the height mismatch between the two tiles you wish to combine. This material is very thin, I'm guessing (from memory) between 1/16 and 1/32 of an inch. Of course you smear thin set mortar under and over this kerdi-band material so you'll get double thickness on the mortar as compared to just laying the the tile directly to a thick mortar bed. It all comes down to technique and experience in the end I suppose. Mortar trowels are really cheap and this Kerdi material is expensive so you could just experiment with troweling the mortar on the target surface and letting it set up at approximately the right finished height. Once it's hardened up you could trowel a thin layer on top of those ridges, at right angle to the ridges, and push your new tiles down. The thin set will push down into the valleys between the ridges and your planarity will match. I recommend that you test this on a scrap board or something until you master the height. The same warning would apply even if you go the kerdi route. Good luck.

can I use this strip to level my wall and install a strip of glass tile?

Asked by Rosca June 22, 2017
1
Answer

You probably could use it behind a strip of glass tile, IF you can apply UNMODIFIED thinset (no premixed mortar) to the wall surface. But this material is only as thick as the fabric of a windbreaker. You need to stick the band in place with mortar, and stick the tile to the band with mortar. I'd save the money on the band and just level the surface with a layer of thinset (you can use whatever you need for you surface), then spend the extra for the special, white glass-tile mortar to place your tile in place.

Can it be used over joint compound on sheetrock?

Asked by AngelCT71 January 15, 2017
2
Answers

Are you also using the Schluter Kerdi waterproofing fabric over your sheetrock? This band is designed to cover the seams between sheets of Schluter waterproofing fabric. If you aren't waterproofing, a paper or fiber mesh tape is a better, and much less expensive option. I would recommend going online to watch some of the videos of the installation of the Schluter Kerdiband before you decide if this is the product you need.

Can I use this to cover expansion joints on a concrete floor?

Asked by matt August 30, 2016
1
Answer

The Kerdibamd is designed as part of the Schluter shower system. It is not intended to cover an expansion joint in concrete. To install the band, you must cover the surface where you will be placing it with UNMODIFIED thinset mortar, there must be no air bubles in the surface behind the band. This is a waterproofing component of a shower waterproofing system, not a product to bridge a gap.

What should I use for mortar to set the membrane

Yes. You mix the mortar a little thinner than what you would use on tiles.

I had a difficult time appling it to the inside and outside corners. On flat surfaces as well. A little adhesive on the product would be beneficial to the person installing it.

This is the product that ties all the components of the Schluter waterproofing system together. Be very careful when calculating how much band to purchase. You need enough to cover all the places that the waterproofing 'fabric' meets, and where the walls meet the shower floor. And if you use the Kerdiboard wall panels, you need a square piece of the Kerdiband to cover all the fasteners holding the panel on the wall. I cut all my bands for the wall & floor seams in advance & creased them by folding the band lengthwise and rubbing the fold across the edge of my work table. Unfortunately, when I calculated how much band I needed, I counted the seams, but _forgot_ to count how many patches I needed to cover the screws hanging the wall panels. It is kind of surprising how much band is needed to cover 100 screwheads. I had to go back to my Home Depot store to pick up another package of Kerdiband. Halfway down the isle to checkout, I turned back to grab a 2nd roll of band, "just in case". I'm really glad I did, because when I started cutting patches, I was still 4 square patches shy of what I needed. I had to open that 2nd roll of Kerdiband. My shower looks great, as far as it is finished. I should never have a problem with leaks. Now, on to covering all that Kerdiband with tile...

This will be my third application of the Kerdi Schluter shower or tub application. Just finished my Master Shower now getting ready to apply the Kerdi system around my Tub. The products are easy to work with and really helps when the walls are out of Plumb. We used 12x24" tiles getting the tiles flat was our challenge but no issue with any application and use, keeping the shower waterproof, no tile cracking or loosening. I recommend using this product as intended to protect the framing and underlayment from moisture damage.
