Kerdi-Board installation begins with checking studs. Studs should even with each other, plumb, and 16″ on-center.

Boards can be cut using a utility knife and installed to studs using Schluter screws and washers; screws/washers need to be 16″ on-center horizontally and 12″ on-center vertically.

Once boards are installed, all seams and screws need to be waterproofed using unmodified thin-set (e.g. Kerabond) or Schluter’s ALL-SET along with Kerdi-Band. Sponge Kerdi-Bond to make it smooth and remove any humps.

Kerdi-Board can be connected to the tub using Kerdi-Fix, Kerdi-Band, and unmodified thin-set or ALL-SET.

  • it is great to work with being so light, but at $100 per 8ft X4ft board + special screws +special washers+ kerdi band+ kerdi fix+ thinset to apply it is a hard sell. Cement backerboard and liquid waterproofing will save you a ton of money. I do bathroom remodels for a living, I use both, I just wished schluter was a bit more price competitive

  • Schluter's Kerdi-Board is very user friendly and convenient, plus tile can be set over it on the same day as installation. Tips in this video hopefully clarify questions about the system. More systems and tiling videos are available inside Bathroom Repair Tutor which now has over 190 detailed video tutorials https://bathroomrepairtutor.com/

  • The grid on the Kerdi board and the Kerdi membrane really comes in handy when cutting and installing tile. Great video.

  • Which foam board board do you use most of the time? Wedi, Hydroban, or Kerdi

  • Great tutorial. Wouldn't the foam board be weaker than a cement board? It seems that if someone fell or pushed against the wall the foam board would cave in or break. I'm sure the tile will give it some rigidity but it seems like cement board with something like RedGard, HYDRO BAN, etc, to waterproof it would be stronger.

  • Super useful vid. I think everyone was confused if the board should overlap the tub flange or butt on top of it. The rabbit cut is a best of both worlds solution

  • Seriously, where do you buy this stuff now? HD, Lowes dont carry it. They only seem to sell full shower kit which I (and I am sure many other buyers) dont really need. The website listed vendors in DC area seem to be remodeling vendors and not resellers of the product.

  • Great tutorial!!! Question! What do you do if you install the kerdi band wrong and the thinset hardened already?

  • Is there another alternative to Kerabond or Schulter all-set? Neither are locally available. I would like to use Kerdi-board and ceramic tile in a bath and porcelain tile in a shower. Mapei large format tile with polymer is all that was recommended at a DIY store.
