What is Schluter Ditra?
- Mix to make a thin-set mortar suitable for the substrate. The mortar should be mixed to a fluid consistency but still hold a notch.
- Apply DITRA to the floor, fleece side up.
- To check the coverage, lift a corner of the mat.
So, should Schluter Ditra be used?
What are the benefits of SchluterA(r),-DITRA for tile installations? DITRA was specifically designed for the installation of stone and ceramic tile on any even or load-bearing substrate. Consistent results are possible thanks to the integration of DITRA's waterproofing, uncoupling, load-distribution and vapor management functions.
You may also wonder if you can use unmodified thinset under Ditra. 1 to install ceramic (including porcelain) and stone tiles over DITRA or DITRA-XL. Portland cement-based unmodified, thin-set mortars require moisture to hydrate in order for them to be strong. DITRA is impervious so it doesn't deprive mortar of moisture.
So, can Schluter Ditra be used on walls?
Yes. Yes. Once KERDI is installed over the drywall panels they will be fully protected from water and vapor in the tiled shower.
What is the time it takes for Ditra to set?
Step 4: Mix Ditra Set Open Time for Ditra-Set takes approximately 20-30 minutes so the guys mixed only what they had.

Can I use Ditra over plywood?
The type of thin-set mortar used to install DITRA depends on the substrate material. For example, to set DITRA over plywood or OSB, a modified thin-set mortar meeting the requirements of ANSI A118. 11 is used.
Should I use Ditra or cement board?
1. Ditra is waterproof, while cement board lets water through but won't be damaged by it. With cement board, the tile is mortared to the cement board and the cement board is mortared to the substrate, so there's a chemical bond. This difference, Ditra fans would argue, makes it more resistant to movement.
How long after laying Ditra can I tile?
Once DITRA has been installed on the substrate, tile can be installed right away. No need to wait for the mortar to cure.
Can you self level over Ditra?
ALL mat manufacturers say to level BEFORE putting the mat down, not just Schluter. Like I said we already level the plywood. Next step is installing ditra with heated floor. On top of ditra we'll apply self leveling compound, let it dry completely so there is no issue trapping moisture between tiles and ditra.
Can you lay tile directly on concrete?
While you can install tile directly on concrete, problems erupt when the concrete cracks or shifts. All of the movement in concrete is transferred to the tile. Cracks in concrete immediately become cracks in the tile.
Is Ditra a crack isolation membrane?
Manufacturer Roundtable: Crack Isolation and Uncoupling Membranes. Laying Schluter Ditra uncoupling membrane over a concrete substrate. Photo courtesy of Schluter Systems. Hydro Guard SP-1 provides a waterproof membrane that also limits the transfer of substrate cracks to the finished ceramic or stone surface.
What is the difference between Ditra and Ditra XL?
What's the difference between Ditra and Ditra XL? 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. 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.
Is Ditra necessary on concrete?
James Morgan agrees with McEvers. Citing Schluter's own description of Ditra as an uncoupling membrane that permits differential movement between a lightweight substrate (such as a wood subfloor) and tile, Morgan says it's “entirely unnecessary” between tile and a heavy material such as concrete.
What is the difference between modified and unmodified thinset?
Unmodified thinset has been around forever. Unlike unmodified mortar, which consists only of a blend of Portland cement, sand, and water retention agents, modified thinset includes additional retention products, such as latex polymers, which can increase its performance and strength.
Do you need a moisture barrier under tile?
Do I need to put any type of underlayment or vapor barrier underneath it? A: It's perfectly acceptable to put tile directly on concrete — with a couple of caveats. Not only will the membrane protect against cracking, it also serves as a vapor management system and protects the substrate from moisture penetration.
What is the best underlayment for tile floors?
Exterior plywood is an acceptable underlayment for tile and is preferred to interior-grade plywoods because the bonding adhesives used are waterproof. If water seeps through the tile installation to the underlayment, it will not cause the wood to swell, as happens with interior-grade plywood.
What is Ditra tile underlayment?
Ditra is a polyethylene uncoupling underlayment with a grid structure of square cutback cavities and an anchoring fleece laminated to the underside. Ditra provides waterproofing and vapor management. Underlayment for tile.
Can you tile a shower on drywall?
The bottom line is that drywall (and this includes moisture resistant drywall) should never be used behind tile in wet areas (showers and tub-shower combinations). This is especially important in a shower located on an outside wall, but also helps even if the shower is on an inside wall.
Can I use Ditra on shower floor?
Waterproofing these floors can save an owner from replacing the tile assembly and substructure in the event of a leak. DITRA-HEAT installations can be made waterproof with minimal effort. If installing the Schluter-DITRA-HEAT inside a shower, we require that the entire installation be covered using the Schluter-KERDI.
