Hardie backer board on Floor ?

[dal5band]

Has anybody used the Hardie backer board for tiling on a bathroom floor (traditional floorboards)?
They reccommend the 6mm board for floors. How do the joints perform - the sheets come in 1200 X 900mm so I will need three sheets.
A lot of people suggest ply but the Hardi board is a lot easier to handle.

Thanks

I've just used 'no more ply' which is the same sort of thing and i was really impressed, it's extremely rigid for saying it is only 6mm thick.
I screwed all boards down first (where neccessary) then pinkgripped the boards to the floor and screwed them down at about 300mm crs.
Fixed the tiles down with BAL single part flexi adhesive.
Theres no real step from my carpet to the tiles and the floor is nice and solid.
Much better than ply!

Can I ask you to post in 6 months time and let us know if it's still going strong? Thanks.

I wasn't being funny mate - it was a serious request.

Apologies, i must admit when i re-read it again i thought.....oops

Sorry, I will let you know. So far its been down for about 4 weeks and despite my 2 1/2 year old sons continual jumping on it, no problems at all.
I would be more concerned had i not used a quality flexible adhesive.

Cheers

No worries, I just didn't want you thinking I was taking the p*ss.
Bal single part flex is good stuff indeed. Hope it works out for ya.
