Schluter-Ditra XL 5/16 Underlayment 175sqft Roll by Schluter

Expensive but necessary to eliminate the saddles between rooms!

Im using this for the first time in order to put tile over a rough OSB subfloor. Its working quite well for me and not too hard to install. The tile has a somewhat softer feel underfoot than the tile I have downstairs directly over concrete. Im glad Im using the Ditra XL because otherwise this tile floor would be too hard to make smooth and even. They have very helpful videos on their website.

My go to for this type of product

exactly as I expected..... delivered in a couple of days

What a good deal compared to other stores anf great product!!!

Worked Great!

Make very very certain that you lay it down very very flat and never fold it. Once you have a crease you are done for. Your floor will not be flat amd then tiling will be a pain

Fairly easy to install, and is forgiving

It can be a challenge to fill the deep waffles, trowel, and lay the tile (but filling the waffles and letting that dry can certainly make that easier!). Matched up perfectly to all of the surrounding 3/4 hardwood flooring. It was also a HECK of a lot easier to carry this 26lbs roll of underlayment vs. almost 500lbs for cement board. My back and aching muscles have to be worth **something**. :-)

I had a problem with cracks in my tile. Had the tile taken up and used Ditra XL. So far so good No cracks
