Hardie backer PDF

[Ian]

I was just having a look at the installation PDF to brush up on a couple of things, just thought I'd post it up incase anyone fancied a read. It was updated in July 2012.

Allways worth a good read.....

I had a blank and couldn't remember if they advised sticking with non-flexi or SPF, turns out non-flexi is advised. Always good to keep up to date with the technical side of the trade

Yeah, 15mm ply or 18mm chip board onto joists spaced no further than 600mm apart. Schluter recommend a non-flexi for sticking ditra down, even over UFH that's what made me look.

Good at least they don't say it's waterproof you need to tank it unlike aqua board

That surprises me to use a non-flex.....

So do I Deano, I can't see it being a problem, would be nice to know what the difference is though.
