Schluter Ditra mat/ Dural CI are not suitable for overlaying chipboard. They are not designed to deal with deflection, more for lateral movement ie. screed shrinkage due to drying, crack isolation, etc.:ban:

If you couldnt replace a chipboard floor (always best if poss) and you have to overlay with ply, I wouldnt tile onto it if it was less than 15mm.

i thought so, thanx for confirming that for me, im still going to use the orange matting it should help abit shouldnt it .

not for deflection it won't. Make sure chipboard is screwed down securely.

it will help if it has some kind of wax or moisture resistance substance on top though but the floor needs to be deflection free.

looks like a few converts to backerboards from ply. For those of you that have, do you still go for the same thickness?

Ok I have a floor to do but the customer is concerned about the height difference from the bathroom to the hallway. Now if I use 6mm Hardi and tile with say a 8mm thick tile what will the height difference be?

 

[White Room]

Nearly 20mm, 2mm addy, 6mm hardie, 3mm addy plus tile

 

[Hawkofeagles]

What do I do as the customer does not want too much of a height difference even though I have said it's the best option??

rip up the chipboard and replace with 18mm wbp ply
