Very frustrating.
I know this product exists but can't find it to buy it. There is a guy on ebay that is selling it for £20. Squirt it around the edge of the board and then make a swirl like a 'W' on the middle of the board he states.

Then there was Luke @ Hardiebacker on Twitter over a year ago stating that this is a game changer.

So how come we are only just hearing about this product?

How much coverage per can?
Do we still need screws?
Can you tile straight away or do you have to wait for the foam to cure?
Will all the Hardiebacker boards have lips?

We all know that expanding foam expands. Will you find that your Hardie floor now sits 30cm off the original substrate!

Come on Hardie guys give us some info.

The cynic in me says that that Hardie want us to 'test' it before it goes on sale.

You could use clips to lash the boards together? Ask Andy and I reckon he'll recommend MUSTANG clips!
That's a good idea. I think we might start seeing green Hardie clips soon!
