Schluter Ditra is a German-made, lightweight, waterproof, uncoupling underlayment. Perfect for absorbing movement and blocking moisture, Ditra is a great option for basement floors, concrete substrates, and outside spaces.
So whether you're tiling a patio, a deck, a basement, a kitchen, a bathroom, or a laundry room, the Schluter Ditra products are the perfect choice for a solid underlayment that keeps moisture issues at bay.
Ditra is 1/8" thick, and can be installed on single layer plywood or OSB subfloors that are over joists spaced up to 19.2" on center. Most common tile floor underlayments are 1/4" thick, so Ditra is a great alternative if a shorter underlayment is needed.
Ditra XL is 5/16" thick, and can be installed on single layer plywood or OSB subfloors that are over joists spaced up to 24" on center. Ditra XL is ideal for installations requiring greater movement accommodation, such as applications using natural stone tiles or large format tiles.
Both can be installed over plywood or OSB, over concrete, and over in-floor heat systems.
Ditra Heat is the hot new product from Schluter Systems.

Schluter specifically calls for unmodified thinset for the installation of Schluter Kerdi. Most big box stores only carry modified thinsets, which won't cure properly when used to install Kerdi.
In 2017, Schluter introduced their own line of specially-designed thinsets, including Schluter All Set, a strong modified thinset approved for use with Schluter's waterproof systems.
Make sure you use either UNMODIFIED thinset or SCHLUTER ALL SET for your installation as specified by Schluter Systems or your installation may fail and Schluter will not honor any warranties.
We stock Schluter All Set in white every day in our store.
