Product Overview

Ditra is a polyethylene uncoupling underlayment with a grid structure of square cutback cavities and an anchoring fleece laminated to the underside. Ditra provides uncoupling through the open rib structure which allows for in-plane movement that effectively neutralizes the differential movement stresses between the substrate and the tile, thus eliminating the major cause of cracking and delaminating of the tiled surface. Ditra provides waterproofing and vapor management. Underlayment for tile.

  • Designed for use with ceramic and stone tile
  • Ideal for interior and exterior tile and stone installations
  • Neutralizes stress that originates in the subfloor to eliminate the main cause of tile cracking
  • Waterproofs and allows moisture in the substrate to evaporate
  • Replaces backboard or a second layer of plywood
  • Polyethylene material
  • 54 sq. ft. roll measuring 3 ft. 3 in. x 16 ft. 5 in.
  • 1/8 in. thick membrane makes transitioning to other surfaces simple
  • Easy installation over a thinset mortar

Answer: 
It would work for any tile. I have seen it used in DIY shows to completely line a shower before tiling. I used in a hall bathroom over a wooden subfloor (12"x24" tiles). It is a lot less work than using backer/cement boards. No screws or joint sealing.

Answer: 
Yes, we used it for our new bathroom floor and it worked quite well. Just make sure you use the correct type of thin-set, unmodified for between the ditra and tile. Use modified thin-set between the ditra and floor if the ditra is placed over a plywood floor. See their website for more information. http://www.schluter.com/schluter-us/en_US/faq

Answer: 
As long as you bought the standard "ditra" and not the "ditra XL" , you're looking at an average total height increase above subfloor of 11/16 inch. ( almost 3/4 inch ) When you factor in the top of the subfloor to the top of "ditra"+ mortar bed + tile thickness, that's the average increase. Of course, there might be variations depending on size of tile. if you're setting a 6x6 tile, you only have a 1/4 Read More

Of course, there might be variations depending on size of tile. if you're setting a 6x6 tile, you only have a 1/4 (mortar) notch trowel, whereas setting a larger format tile, your mortar should be spread using a 1/2 (mortar) notch trowel. If all you wanted to know, was how thick " Ditra" is, it's 1/8 inch. Read Less

I, therfore, used modified thin set mortar on the wood sub-floor; placeed ditra (felt side down). pushed out all bumps from under ditra. This step is extremeky important as the bumps may not be obvious. Unmodified thin set mortar is applied next. This can be done right away as there is no need to wait for curing. Make sure that all the squares are completely filled with motar by trowelng in all directions as a mechanical bond is achieved by the dove- tail design of the squares on the ditra.
If installing ditra onto concrete you should use unmodified mortar between concrete and ditra and between ditra and tile. Read Less

Ditra will only add an additional 1/8" to your finished floor elevation. Allow for usual thinset installation plus 1/8". Ditra also makes a 5/16 " membrane if you need to match up to 3/4" adjoining floor elevation.

Answer: 
It needs to dry. We had tile professionally installed and he waited a day to come back to install the tile. You can't walk on it while the thinset underneath is still wet-- I'm guessing that's why. I copied the "professional" and did another room. It's really just easier to lay the whole room with ditra and then the next day, lay the tile.

Rated 4.6 out of 5 by 48 reviewers.
Rated 5.0 out of 5.0 by shower walls with ditra taking apart an existing non-functioning shower to the studs, i re-built it with ext ply (instead of cement board), fiberglassed the bottom 1' walls (and shower pan) then covered the walls with thin-set, applied the ditra, then thin-set the tiles. method was far more flexible, easy to use, cut with just scissors. tiles adhered perfectly. Not the 'contractor method' i know, but then neither was the tiling. August 16, 2016
Rated 5.0 out of 5.0 by Ditra 54 sq. ft. 3 ft. 3 in. x 16 ft. 5 in. x 1/8 in. Thick Uncoupling Membrane no competitive products to compare price or reviews to. August 11, 2016
Rated 5.0 out of 5.0 by Great price for great product I use to use cement board under tiling projects until I discoveted ditra (and kerdi for showers). So much faster, easier and less messy to use, but one pays a bit of a premium for that convenience. For a countertop tile job I went to hd for ditra and discovered that hd is pushing another similar product and the ditra was priced at about one-fourth its usual price. Great! Bought two rolls instead of just the one I needed. June 28, 2016
Rated 5.0 out of 5.0 by great product but expensive used 3 rolls of this for underlayment in 12x12 kitchen. very easy to cut and install. made for a much improved and solid, flat subfloor. Lines, rows in the product make it easy to install tile. the squares in the product make for very solid suction when laying tile July 7, 2016
Rated 5.0 out of 5.0 by Great Product....sucks that the Depot doesn't stock it in store anymore!!!! "Ditra" is the only underlayment I use in my own home, and for installations in customers' homes also. I recently found that the stores in my area no longer stock it. They switched to a generic brand. That just let me know to order "Ditra" in advance of my tile jobs. I've been installing tile over "Ditra" for 5 years now, with zero complaints of shifting, grout cracking, or lifting tiles. Far and away the best substrate you can EVER install underneath tile floors!! June 14, 2016
Rated 5.0 out of 5.0 by Ditra Great product and easy material to work with. Much faster than putting down rock board. July 5, 2016
Rated 1.0 out of 5.0 by Ditra does not stand behind claims. I would never purchase Ditra ever again. I spent almost $7,000 to do my entire house, had some cracking in a powder room, called the Ditra rep and they denied it for several stated reasons: they don't know whether it was installed correctly (Wow, I didn't know they had to be there throughout the entire installation process!); the powder room is roughly 5' x 8' and they said I should have installed expansion joints - are you kidding me, expansion joints in a 5' x 8' residential powder room. By the way, it took me months to actually get a hold of a Ditra rep after leaving repeated messages. He treated me like a criminal from the minute he got to my house - you could tell immediately that they were not going to assist in any way. It does not appear to me that customer service or standing behind their product is a top priority for Dietra. Check out how the Ditra competitors stand behind their product before spending your hard earned $. April 22, 2016
Rated 4.0 out of 5.0 by A great underlayment alternative This can be used as a replacement for typical Hardiboard, cement board, or similar products that need to be screwed in place and sealed. Ensure subfloor is clean and secure, cut Ditra to size, apply a thin coat of thinset to floor, and then place Ditra on the floor. Press it into thinset with your grout trowel to smooth it out. You can start laying tiles right away. It is a fairly expensive product, but it saves a ton of prep time and does what it is supposed to do. Also, the cost of other underlayment and installation is eliminated for the project. The waffle texture really grabs onto the thinset and gives a good bond to the tile. You may use a bit more thinset than normal, but that stuff is cheap. The product can be used on vertical as well as horizontal surfaces. Makes a nice water proof barrier. February 10, 2016
