KERDI-BOARD Installation

You want an amazing tile shower.

High five.

Our last tutorial shared why a solid surfaces is an absolute MUST for tile.

We showed you step-by-step how to install cement board.

In case you missed it just click here.

Cement board is great but can be one of the biggest pains in the butt.

It’s heavy, hard to cut and has to be waterproofed to prevent mold & mildew in the stud bays.

 

Is there an easier option.

You bet your shorts there is!!!

Foam boards are becoming more and more popular.

Why?

Here are a few reasons

  1. They’re light
  2. They’re easy to cut
  3. They’re fast to install
  4. They’re 100% waterproof
  5. They’re more insulating than cement board

KERDI-BOARD is one the best boards on the market.

We firmly believe anyone can install KERDI-BOARD in one day and be ready to tile the next.

Today’s video tutorials walks you through the KERDI-BOARD installation step-by-step.

In less than 12 minutes you’ll see why we it’s a better option than cement board

Watch the video and see our complete installation of KERDI-BOARD

 

As you can see, KERDI-BOARD is easier to lift and cut versus cement board.

Plus it’s warrantied by Schluter…and that should give you peace of mind.

    Hi Jeff,

    What is special about unmodified thinset?

    Thanks for posting this, I see that the Schluter products are available not too far from our town, I am definitely considering this when we re-do the bathroom.

    1. Unmodified is what Schluter recommends between the KERDI-BAND and KERDI-BOARD.

      I pulled this explanation from their website (easier than typing, haha)

      What type of thin-set mortar should I use when installing ceramic and stone tile over Schluter®-KERDI?

      Unmodified thin-set mortar is recommended to set ceramic and stone tile, including large format tiles, over the KERDI membrane. Portland cement-based unmodified thin-set mortars are dependent on the presence of moisture for hydration in order to gain strength. Since KERDI is impervious, it does not deprive the mortar of its moisture. This allows the cement to properly hydrate, resulting in a strong, dense bond coat. In fact, after the mortar has reached final set (usually within 24 hours), unmodified thin-set mortars achieve higher strengths when cured in continually moist conditions. With applications of tile on ceilings, it may be necessary to provide temporary support for the tile until the thin-set mortar cures.

      Exceptions: Certain moisture-sensitive stones, e.g., green marble, or resin-backed tiles may not be appropriate for use in wet areas or may require special setting materials. Please consult the stone supplier and Schluter®-Systems for more information.

      Modified thin-set mortar is not recommended to set ceramic and stone tile, including large format tiles, over the KERDI membrane. Modified thin-set mortars must air dry for the polymers to coalesce and form a hard film in order to gain strength. When sandwiched between two impervious materials such as KERDI and ceramic tile, including porcelain tile, drying takes place very slowly through the open joints in the tile covering. [According to the Tile Council of North America’s Handbook for Ceramic Tile Installation, this drying period can fluctuate from 14 days to over 60 days, depending on the geographic location, the climatic conditions, and whether the installation is interior or exterior]. Therefore, extended cure times would be required before grouting if using modified thin-set mortars between KERDI and ceramic tile, including porcelain tile. If extended cure times were not observed, the results could be unpredictable. This is even more important to consider in wet areas such as showers as there is the additional concern of latex leaching.

        Thanks! I will have to re-read this a couple of times. So much to learn.

        Have a good weekend,

        1. Glad to help any time Sue, send your questions my way. I’d be happy to help 🙂

    Do you have a video that shows the proper way to make a custom shower pan with ceramic tiles on the floor and walls?

    1. We will have a video showing how to set a custom shower pan from KBRS. I recommend checking out the pans from KBRS if you want a custom pan and curbed shower. You can oder any size you want and tile directly on top of the pain with no prep work.

    Hi Jeff,
    I bought the Kerdi board Nitch with a shelf. I am assuming that the Kerdi-fix is sufficient to hold the shelf in place and will withstand the large shampoo bottles but I want to make sure. Thanks for your help and for the Videos. I love the Schluter products. It has made the project so much easier for me as a beginner.

    1. David says:

      I have the same question as Ellen. It appears we should tile the back and sides of the niche up to where we want to place the shelf. The shelf will rest on the tiles and we use the thin set to kind of “glue it” in place.

  4. Joe Fatta says:

    Is wedi board the same to install as kerdi-board

    1. Joe, Wedi is a bit different than KERDI-BOARD in that the cementicious layer can be cut and still be waterproof. Ideally you wouldn’t want this to happen but that’s one big difference. It’s the same process to install with the screws and washers, but Wedi requires Wedi sealant at screws and seams.

  5. Anthony P Myers says:

    I would like to see more about the wedi installation around a tub, as we’ve purchased wedi and became confused as wedi wants the board to be placed over the tub surround about 1/8 inch above tub surface which seems different to kerdi or other installation methods and yes im a novice…lol thanks and great site!

  6. Janice says:

    did look on your video i can not hear but I looked them anyway what kind of screws to put on the Kerdi board? i can see round flat with screw in the midd;e and then put pink masking tape . round flat comes togeter with screw ?

  7. sinclair says:

    in your discussions you never mentioned cost factors. i am familiar with cement board and using red guard to waterproof it (tanking) so my question is with the kerdi or wedi board systems, when completed are they more or less costly to install on average? i am referring to from start to thin set stage because i would think that the actual tile cost would stay the same.

  8. Bill Gonce says:

    Hi Jeff … how would you handle an outside corner where Kerdi Board meets Kerdi board. This is in an area where a shower meets a wall that will also be tiled. I will be using a Schluter to give a finished look where the tile meets but what do I need to do to prepare this outside corner prior to tiling? (kerdi band also?)

      Hi, Jeff,

      Do you have a video showing how to install a Tile Redi shower pan ? Thanks.
