Hi, Used Ditra matt today on a 45m area, no problems there, but the floor is not flat in places.
Fixing 600 x 600 x 20 mm lime stone on this and was thinking, should I laytex on Ditra or not and just double bed the tiles?

Should have flattened it out first methinks??

Did you not check the substrate before using the ditra..?

Just use a ptb and pack where needed...

Zenman - I think I would have levelled the floor before laying the Ditra matting.

Timeless John.

Its not that bad, a 6 ft level sits flat no problem, but I know what these tiles are like.
Was not sure if I could put a leytex down.

If your level sits flat then no worries...use a PTB adhesive and a larger notch trowel and backskim the tiles and you will be fine..

Thanks guys, it's not that I was worried, more of a question.
New build, everyone in the way, time and deadlines all dictate laytex.
In an ideal world I would have laytex the hole floor first as you said.

Nowt worse than bieng rushed on is there....
