cement board is good for over boarding floors where height is an issue, i use nmp as is it available locally and Hardie isn't, but I use cement board as 6mm is within most most manufacter recomendatio s for over boarding a chipboard floor, where as I this k it's minimum of 10mm xps board

Where do you get that from locally

Cement board has its place. But i would always use 10mm Wedi type boards on floors over 6mm cement board most of the time.

I used nmp in a shower/steam room on 3 walls, installed 2 years ago and had no issues with tiles etc.
