Foam for fixing cement boards

[Blunt Tool]

Had heard about this, supposed to replace adhesive AND mechanical fixing?

 

[Qwerty]

I've heard Hardi raving about it on social media!

 

[On one]

I got the hard sell the other day at a CTD promotion, I was offered more Hardie FOC if I bought the foam.
I said I wasn't convinced, then the Hardie guy just switched off and walked away!!

Andy Carroll says its good. So it must be good.
This month at least...

(it'll be something else next month...)

Does it still need the screws? What about filling voids etc on substrate?

I'd like to see or hear how they suggest doing that, is it like mega strength nmp stuff ?

 

[Blunt Tool]

I think I would still be screwing

I think I'll stick to using better products than cement board!
