Hardiebacker v's Ply confusion

[Holohana]

i guess you can therefore use 6mm hardibacker because the adhesive bed vreates the rigidity then?

Waivers, are they actually worth the paper they are written on?

Does anyone find that 6mm Hardiebacker is actually "flat"?

Sounds like the old story, builder is trying to save money by giving you at the least a concern. I am with the others in that if he doesn't prep the job the way you want then it is not worth the hassle. However if it is small units and you are happy that the floors are rigid enough with 6mm ply then that is your call. The 6mm hardi would be more rigid than the 6mm ply but it looks like he doesn't want the extra expense.

To be honest grumpy I've had no problem with the 6mm and it allways look's flat and certainly when laying tile's has'nt given me any cause of concern.

The area is 85m2 so comes in at just under at £1,000 for the boards plus addy plus labour. He balked at the total cost and said he’d just use what he’d already planned to do.

:47: He balked, and then disregarded your professional advice? I'd walk. Really, I would, and that's not even considering the price is nigh on ludicrous. I wouldn't ever do something which I couldn't leave a warranty on with good conscience. If I was short of work, and I needed the job anyways, I'd make the customer sign a waiver, which would stipulate that I couldn't be held responsible for any potential troubles caused by the substrate.
