How to install Schluter-Ditra Membrane. This process is pretty simple as long as some basic steps are followed. Leave an edge about 1/4 inch all the way around. Make sure to use a modified thin-set. Wet the plywood or OSB before applying the thin-set. Spread out the thin-set with a 1/4-3/16 trowel. Float the Schluter-Ditra.

What do you put under Schluter?
What type of thin-set mortar should I use when setting tile over Schluter™-DITRA and Schluter™-DITRA-XL? Schluter-Systems requires the use of Schluter SET™ , ALL-SET™ , FAST-SET™, or an unmodified thin-set mortar meeting the requirements of ANSI A118. 1 to install ceramic.
Do you put Thinset under DITRA?
The type of thin-set mortar (modified vs. unmodified) used to install DITRA depends on the substrate. For instance, to install DITRA over plywood, a modified thinset mortar should be used. However, over concrete Schluter recommends an unmodified thinset mortar like the Ditra-Set shown here.

Should I use cement board or Schluter?
Schulter Ditra or Cement Board (Hardibacker, Durock, Wonderboard, etc.) is typically used as a tile substrate because it is durable, water resistant, and does not expand, contract, or warp when exposed to moisture. Schluter Ditra is superior to cement board in all categories except price and durability.

How long to let Schluter dry before tiling?
24 hoursWait 24 hours after the membrane (i.e., Schluter®-KERDI-BAND and Schluter®-KERDI) installation is complete to allow for the final set of the mortar and to ensure waterproof performance of the assembly at seams and connections before water testing.
Is Schluter really waterproof?
Schluter®-KERDI is a pliable sheet-applied membrane. What makes it a particular advantage is that it's completely waterproof and vapour-retardent. It's been designed specifically for the direct application of tile.
What do you put under Kerdi membrane?
Typically, cement board is the best substrate for Kerdi Membrane installation on walls.
Can Schluter go on drywall?
Yes. Once you install KERDI over the drywall panels, they will be completely protected from the water and vapor in your tiled shower.
Can Schluter membrane go over cement board?
Schluter says that the Kerdi membrane and tile can be installed over standard gypsum wall board without any problems.
How thick does the subfloor need to be for DITRA?
DITRA allows for ceramic tile application over single-layer plywood or OSB subfloors on joists spaced up to 19.2" (488 mm) o.c. DITRA-XL is 5/16" (7 mm) thick, which permits even transitions between tile and 3/4"-thick hardwood flooring.
What is Schluter DITRA Matting?
The key to understanding why this membrane will greatly enhance the structural integrity and durability of your tile floor is to get a good handle on just what Schluter-DITRA is. By the way, contractors sometimes refer to this product simply as DITRA, and we will too.
What is a concrete subfloor?
Concrete Substrate: Concrete is a challenging substrate to cover with hard flooring such as tile and natural stone. The major reason is that concrete can expand nearly twice as much as ceramic tile and grout.
How much does a CBU backer board cost?
By comparison, CBU backer board cost is $0.70 to $1.10 per square foot. Many professional tile setters believe that the higher cost of DITRA is offset by the fact that it takes less time to install than CBU does due to its ease of use. Less installation time produces lower estimates from contractors and less hassle for DIY installers.
What is a ditra membrane?
The term refers to the fact that the DITRA material prevents the tile mortar from sticking to the subfloor. It can be confusing because when we hear “uncoupling,” we think of something being coupled or connected first. In reality, the DITRA membrane prevents the coupling in the first place.
How long does it take for modified thin set tile to dry?
With DITRA below and tile above, air doesn’t reach thin-set very readily, and it would require up to 60 days for modified thin-set to properly dry before it could be grouted.
What is the O.C. for porcelain tile?
16” or 19.2” O.C. (on center) joist spacing with single-layer OSB or plywood subfloor for ceramic and porcelain tile installation
Can you use ditra underlayment on OSB?
Wood Substrate: OSB, plywood and framing members should be covered with a material such as DITRA underlayment because wood is very susceptible to changes and to moisture. Wood expands and contracts with moisture and temperatures changes and flexes when bearing loads. These movements will damage tile and grout without the presence of a flexible, motion-absorbing material. Wood will also be damaged by water, something this polyethylene membrane prevents. DITRA can be installed over these wood subfloor systems:

How to install Kerdi membrane?
To install Kerdi Membrane, start by applying Schulter ALL-SET mortar (or similar) to your cement board substrate using a 1/4” x 3/16” V-Notch Trowel. Cut the Kerdi membrane to size using a utility knife or scissors. Press the Kerdi Membrane into the Thinset Mortar with firm, even pressure to achieve full mortar coverage. Remove any excess thinset mortar from underneath the membrane using the flat side of a trowel or a putty-knife.
What substrate should I use for Kerdi membrane?
Before Kerdi membrane can be installed, you need to have a properly prepared substrate. Typically, cement board is the best substrate for Kerdi Membrane installation on walls.
What is Kerdi Membrane?
Schluter Kerdi membrane is a flexible, sheet applied waterproofing and vapor-retarder membrane that is typically applied to shower walls, bathtub surrounds, and other tile applications where moisture will be present. Kerdi Membrane is designed for direct tile application.
How to remove air bubbles from Kerdi membrane?
Remove any excess mortar or air bubbles from beneath the Kerdi Membrane by “sweeping” them to the side with the flat side of the trowel.
How to embed a Kerdi membrane into a thinset?
Once a sufficient amount of thinset mortar has been applied to the substrate, press the Kerdi Membrane into the mortar, fully embedding the membrane into the thinset.
How to apply thinset mortar to a wall?
Once the Kerdi Membrane is cut to size, apply thinset mortar to the walls/substrate using a 1/4” x 3/16” V-notch trowel. Apply thinset mortar to the substrate using “directional trowel ing” – meaning that all trowel marks run in the same direction.
What is substrate tile?
The term “substrate” is simply defined as the layer underneath your tile. Although most...
Does a KERDI band need to be sealed?
all seams in DITRA-HEAT and DITRA-HEAT-TB matting and floor/wall transitions must be sealed with KERDI-BAND using unmodified thin-set mortar. Note: KERDI-BAND must lap DITRA-HEAT at seams and at floor/wall transitions by a minimum of 2" (50 mm) in order to maintain waterproof integrity
Can you put furniture over a floor temperature sensor?
Do not place furniture or mats over the floor temperature sensor. They can act as insulation and raise the floor temperature reading at the thermostat. This may cause the heating to turn off before the remainder of the floor reaches the desired temperature.
What seams do Schluter use?
Now there are a bunch of seams I need to waterproof. The Schluter system uses Kerdi bands and corner seals as I mentioned before.
Why use a Schluter shower pan?
As I mentioned in my planning post, I chose the Schluter system shower pan because I was unable to move my drain and it is relatively easy to customize to your needs.
How deep should a shower pan be?
One side is flat, and the other has little teeth. The teeth can be a variety of depths, but for the shower pan, it required a 1/4 by 3/16 inch notch. Using the flat side of the trowel, I spread the thin-set evenly around the area, making sure to extend the area a little farther than the shower pan will lay.
Which side of the trowel do I use for thin set?
I started by applying the thin-set with the flat side of the trowel and adding more with the v-notched side.
