Cement board and Ditra

[Dumbo]

Hi, this is what I've been advised (new conversion with green chipboard glued and screwed - no movement) but my concern is replacing the floor in 5 years time and pulling up the ditra in the future will destroy the chipboard. Am I being too negative or would laying a 6mm backer be best? Only a 3m2 ensuite with porcelain tiles.

Thanks

Dont be concerned about what youre going to have to do in five years be concerned about it lasting five years

Ditra on chipboard is wrong advice, 6mm hardibacker glued screwed and joints taped is the right way..

I use it on chipboard floors as long as its not the wax surface type and the floor is solid, as it would need to be with hardie / bal boards anyway. I use ardex af 200 plus.
