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

I have completed several tile jobs using the Ditra underlayment, after using cement board for years. The huge benefit is that it can be cut with a razor blade, although it still needs to be cemented down to the subfloor using thinset (as cement board does). The difficult, and time consuming part is trying to fill in all of the squares with thinset when laying the tile. You must move the trowel back and forth in all directions to get the air bubbles out and get every square filled in with thinset. It is very aggravating! I guess its still easier than cutting cement board to fit and installing all the screws in the cement board.

This did not meet my expectations. It is difficult to get fully adhered to the subfloor at the edges. The deep waffle indentations are difficult to completely fill. I am removing this.

great price and as advertised

Awesome product, really fast install. Love it, so much better than concrete board.

Went in great. The XL has the same height as a 3/4 inch hardwood floor when everything is installed.

This was recommended to us by a tiler working a neighbors house. We used it because another neighbor had had a lot of trouble with cracked tiles and we wanted to avoid that. It was easy to put down -- a lot easier than cement backer board -- and the tile went down on top of it with no problem. A warning: if you are doing the work yourself and plan to take your time, be aware that the orange stuff is not comfortable to walk on without shoes!

The XL was great option to the standard 1/8” ditra.

Great product and easy to install, especially if you follow the instructions. Make sure to buy the correct trowel size to install.

love this product

Not worried about my large travertine tiles breaking over the years. Sturdy and strong underlayment. Love the schluter system...we waterproofed our whole shower using Kerdi. Great reliable stuff.
