ditra over former - TilersForums.com

I have a Tuff2 shower tray installed, I have just purchased some ditra uncoupling matting.
Should this be installed over the entire tray or just butted up to it and then taped across on to the former. The matting is a lot stiffer than I thought it would be and I am concerned about losing my falls.

The former would need their kerdi (tanking membrane), the ditra would need to come upto the tray and the kerdi overlapping onto the ditra by 100mm if not more....

Yes you can use the Dural Ci over the tray, the drain cover will wind up enough to accomodate.

Also make sure you sand the tray to create a good key for the flexible tile adhesive , just to add to create a really strong bond the use of mapei eco-prim grip will aid in that and then no need to sand the tray as the eco-prim grip will adhere no problem.

In tanking could someone give me the order please. Floor in Ditra and the walls in Kirdi, but how about the tape in the corners, does the corner tape go in before or after the sheet tanking membranes .
