Is Kerdi-Band worth it over a generic waterproofing band?

If you are already using Kerdi Membrane, Kerdi-Board or Ditra, Kerdi-Band keeps the system matched and approved, which matters for warranty and inspection. A generic band may cost less but is not part of the Schluter assembly.

How much area does one roll cover?

One roll is 16 ft 5 in long and 5 in wide, about 6.8 square feet of strip. That is usually enough for the seams and corners of a standard shower, but measure your layout first.

What thinset do I use with it?

Use unmodified thinset, as Schluter specifies for Kerdi and Ditra. Embed the band with full coverage on both sides; gaps in the mortar are where leaks start.

Can I use it with Ditra on a floor?

Yes. Kerdi-Band is compatible with Ditra and Ditra membranes and is commonly used to seal floor-to-wall transitions and seams.

When is the price lowest?

The best new price was $17.50 at eBay as of November 4, 2026, against a recent daily range of $19.97 to $30.13. Prices vary by store, so check the roll length and width before ordering.

Our take on the Schluter Kerdi Band Waterproofing Strip

Kerdi-Band is a 5-inch-wide, 16 ft 5 in roll of polyethylene waterproofing strip with a fleece backing, made to seal seams, corners and changes in plane in Schluter's Kerdi and Ditra shower systems. It installs with unmodified thinset over Kerdi Membrane, Kerdi-Board and Ditra, and the pliable band bends into inside and outside corners. The best new price is $17.50 at eBay as of November 4, 2026, below the recent daily range of $19.97 to $30.13. Seven stores list it new, so compare roll length and width before buying.
