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.

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.

Review 3 for Ditra 54 sq. ft. 3 ft. 3 in. x 16 ft. 5 in. x 1/8 in. Thick Uncoupling Membrane
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.

Review 5 for Ditra 54 sq. ft. 3 ft. 3 in. x 16 ft. 5 in. x 1/8 in. Thick Uncoupling Membrane
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.

Review 6 for Ditra 54 sq. ft. 3 ft. 3 in. x 16 ft. 5 in. x 1/8 in. Thick Uncoupling Membrane
First tiling job ive ever done. Nothing huge, just a 6x6 bathroom floor. But I figured I better do it right the first time. Very easy to cut and work with. Like the directions say you need Modified mortar to lay the Ditra down, but then you need Un-Modified mortar to stick the tile to the Ditra. When I purchased the Ditra, home Depot did not offer Un-Modified mortar. Schluter, the company that makes Ditra, said that if you use Modified mortar on top of the Ditra, it could take anywhere from 15-60 days to fully dry. Again great product, just make sure you get the propper thinset mortar.

Review 7 for Ditra 54 sq. ft. 3 ft. 3 in. x 16 ft. 5 in. x 1/8 in. Thick Uncoupling Membrane
4/5 stars because I've only had tile on it for less than a year. Easier (but more expensive) than backer board. Makes tile flooring much less of a hassle. I put it in exactly as Schluter recommends, and if it holds up as advertised, I will be extremely happy with it.
Pros: High Quality of Material, Easy to Install

Review 12 for Ditra 54 sq. ft. 3 ft. 3 in. x 16 ft. 5 in. x 1/8 in. Thick Uncoupling Membrane
After our neighbor raved about how great this was, we decided to use it in our rather large master bath. This was so easy to install in the bathroom and did not leave a height differential with the adjacent bedroom. HOWEVER, after applying the retro 2 inch hexagonal tiles after about 6 weeks the grout started coming out between the tiles. Thought it was bad grout, so we removed all the grout around the problem areas and regrouted. Same thing happened again. So then we thought the tiles did not have enough adhesive, so we removed them and reapplied and regrouted. Still had the same problem. This may work great with larger tiles, but for smaller mosaics, it is a huge waste of money. I do not think the geometry honeycomb pattern gives enough support to the smaller tiles. Ended up tearing up the entire floor and using board material as the underlayment. A very expensive mistake.
Pros: Easy to Install
Cons: not for use with mosaic tiles

Review 14 for Ditra 54 sq. ft. 3 ft. 3 in. x 16 ft. 5 in. x 1/8 in. Thick Uncoupling Membrane
home depot does sell the ditra - but nothing else that works for it. Dry Set mortar is a MUST. Additionally a 75 lb - 100 lb roller will be needed to embed in the thinset mortar. do not recommend the custom blend dry set - ditra that the home depot has -- it will not stick to it. - Nor do they sell the banding or the correct 11/64 v notched trowel. - the product is fantastic only if you find the other materials elsewhere. Do your hoomework and research this product before buying for your needs.

Review 17 for Ditra 54 sq. ft. 3 ft. 3 in. x 16 ft. 5 in. x 1/8 in. Thick Uncoupling Membrane
I've tiled several floors in the past homes I've owned and this product is the greatest thing since sliced bread. It's a little more expensive than using a concrete backer board but it's much easier to cut...especially for those rooms that have angles or will require lots of cuts. Great application for concrete slabs as it will prevent future cracks in your slab from transfering up to the nice tile you just layed.

Review 18 for Ditra 54 sq. ft. 3 ft. 3 in. x 16 ft. 5 in. x 1/8 in. Thick Uncoupling Membrane
I used this for my upstairs bathroom in a 100 year old home. had to pull up the hardwood sub floor due to plumbing needs and put down plywood. This product made a smooth transition between old and new sub floors and made it real easy to set the tile as well. I am currently remodeling my kitchen and will be using it again. It's just more expensive than backer boards, but worth it.

Review 19 for Ditra 54 sq. ft. 3 ft. 3 in. x 16 ft. 5 in. x 1/8 in. Thick Uncoupling Membrane
Very expensive and tricky to install

Ease of installation
No, I do not recommend this product.
I used this product over a cement slab and definitely will not use it again, due to several difficulties. Because of the flexibility of the product, if you use a grout float to set the sheet(s), as the instructions suggest, it will cause the mortar underneath to move away from the pressure. This leaves waves which are very difficult to see on the orange waffle surface, and nearly impossible to fix. Also, plan on 2 1/2 to 3 times the mortar you would use for a normal job - a bed under the ditra, another layer to fill the holes, then a third layer to set the tiles. That combined with the exorbitant price of the membrane makes for a very expensive installation.

Review 20 for Ditra 54 sq. ft. 3 ft. 3 in. x 16 ft. 5 in. x 1/8 in. Thick Uncoupling Membrane
We tiled a bathroom in an old house without it and had to pull it up and redo because the tile keep breaking loose from floor. I recommend this product to anyone. We are planning on retiling our kitchen soon, we are planning on using it again.
