Tiling onto chipboard?

[Old Mod]

I've seen a couple of failed floors recently where ditra was used directly over chip board, granted I don't know what adhesive was used but, they had failed none the less. Only small bathroom floors, 3m max.

This is one of the points raised when I spoke with @Glynn yesterday,
TM prefer use of board in these situations over decoupler.

This was atopic I was leading into with my polypipe UFH post a few weeks back.

I don't know if it's people not understanding it's actual usage, or maybe being misinformed. But it's for lateral movement not defection. (not that I'm saying a backer is)
If the chipboard still has bounce then ditra is money down the drain.

Small pun there.

What was the reason/symptoms of failure on the one you looked at @Bri?

Deflection, chipboard was just nailed to the joists and had worked loose over a short period of time, most of the grout had either hairline cracks or had big chunks missing.

I've used Ditra before on a bathroom floor 2.5sqm. no deflection and screwed down. Ditra, rapid set flex and rolled using an amtico roller. I would only ever do this is a very small area where there is not much foot traffic.
