I try not to use rapid set unless I really have to I like standard set it's easier to keep ur tools and equipment clean or am I being a lunatic haha

If time isn't an issue then standard set is the way to go

Totally agree, movement would be more than alternative substrates, no need to risk it now with superior options

Talked a customer out of Polypipes spec on same in January, went straight down on pipes and insert boards instead as I couldn't get my head round tiling on the ply..

As Impish said......Ardex AF200 to stick down the Ditra. You can then start tiling straight away.

If you use rapid (remember you must use rapid onto ply) then you have to wait for the adhesive to harden before you walk or tile onto the Ditra.

If you use slow set to tile porcelain tiles onto Ditra then give it a few more hours drying time.........this especially applies in the Winter time.

I'm using rapid to bond the ditra it's gonna be laid Wednesday and possibly Thursday then start tiling Saturday so it's got plenty of time to cure
