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

HardieFloor for under floor heating
For clients who desire the comfort of under floor heating, HardieFloor® is the perfect solution. Unlike wood, it won’t swell, shrink, expand or buckle due to temperature changes and its thermal conductance properties mean that the heating system will react faster and can help conduct more heat into the room.

Why do you have to use rapid only on ply, or wait for adhesive to dry before tiling?

if it's not dry when you start to tile and you need to lift a tile you put the mat up as well
