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

Once ditra is installed with wet thinset underneath, can I install tile that same day or does it need to dry?

Asked by: jjj
The manufacturer says that you can install floor tile immediately; I have never done it but they say yes.

can this be used in place of backerboard for shower walls

Asked by: robin
Not recommended. There is another Schluter product called Kerdi which is designed for this purpose.

How many rolls do I need for 501 sq ft.

Asked by: cats
9.27 so I guess ten, unless you can buy a little bit separately. You can buy smaller bits of this...

Ditra 54 sq. ft. 3 ft. 3 in. x 16 ft. 5 in. x 1/8 in. Thick Uncoupling Membrane is rated 4.5 out of 5 by 54.
Rated 5 out of 5 by from Very reliable and less time consuming than traditional backer boards.... Very reliable and less time consuming than traditional backer boards.

Rated 5 out of 5 by from Great product but do your homework I think this is a great way to waterproof and do underlayment in one pass. I don't think you need the roller, a grout float does a good job. Even those funky thick soled flip flops, the wife just skated around. But it does take some work. You need UN modified thinset between the Ditra and the tile AND it uses a lot more than normal, I'd figure almost 50% more thinset than normal. Agree with prior reviews, HD should carry the seaming product and a better UN modifed thinset, Ditra has a branded product now. Time will tell, I've just used exterior plywood in the pas, but this is the first bathroom I've tiled.

Rated 5 out of 5 by from awesome product if you do it right I've installed in bathrooms, utility rooms, kitchens and on counter tops. Works excellent. The Versabond Home Depot sells will work between wood substrate and Ditra, but Home Depot does not sell a good unmodified. Custom Blend just doesn't cut it. You must use a premium unmodified mortar between tile and Ditra (no polymer!! it's not supposed to stick to the Ditra!). Mastic is not recommended. All premixes contain polymer. 11/64 trowel is not required, Schluter themselves even say so. I used a 1/4 x 3/16 v-notch trowel that they say is ok to use. Home Depot sells this. You don't need a roller to embed it, i use a grout float and it works just fine, pull up a corner to check for proper coverage. Back butter your ceramics. No one says you can't use it with concrete backer board. The more insurance the better. This is a lifetime floor if you follow Schluters instructions. Their FAQ can help you sort through who is giving you the right information.

Rated 5 out of 5 by from Ditra or Hardibacker I did two DIY floors in my 100 year old house, one with ditra and one with hardibacker. Both worked. The main difference is Ditra provides more strength against breaking tiles, while hardibacker provides for a flat floor. Ditra mimics the subfloor underneath, while with hardiboard you can really flatten out an irregular subfloor. Thus my ditra floor has held up great despite me using too much Mapei Ultraflex 2 to try and level tiles. Ditra's technology is sound and its width can help you on transitions to other rooms but ditra won't be a big help in flattening out a floor. You can make up some that problem in added or removed thinset, but if that's a big concern go with hardibacker. If your floor is fairly flat, I'd trust the Ditra system.

Rated 5 out of 5 by from Why not kept in stock? My local Home Depot kept this product in store stock for years and I bought and used it on numerous professional jobs. I finally got around to a personal tiling job in my laundry room and powder room -- discovered that HD had decided to replace it with an unknown competing product with no track record! The competing product's brand is a "known", Red Guard, known for a brush-on waterproofing membrane which does have a track record. Red Guard's uncoupling membrane is pennies cheaper to the consumer. I refused to risk my job. Ditra is still available via special order from HD -- this marketing / stocking decision makes no sense........I guess the profit margin must be better on the unknown product but the profit margin is zero if no one buys it!

Rated 5 out of 5 by from Great stuff I used it on my first tile project, and I will use it again. It was extremely easy to work. Would recommend it to anyone to use. On a side not, there is a thicker version (Ditra XL) that can be used if trying to match height with something like hardwood flooring. Not sure why HD doesn't offer that as well. Only bit of advice would be to use a little bit more water when mixing the thin-set that goes between the flooring and underside of the Ditra.

Rated 5 out of 5 by from 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!!

Rated 5 out of 5 by from Ditra details Before installing this product do your home work as there are some inportant diffferences than using backer board: type of mortar, make sure you push out any accumulated mortar under the ditra tht would cause bumps in the ditra as the bumps may not be apparent, be sure to trowel mortar in all directions with staight edge of trowel to push motar under edges of the little squares before trowling on additional mortar to set the tile, its the dove tail design of the ditra that mechanically holds the motar and tille to the ditra
