Aquapanel or Hardibacker

[grumpygrouter]

Hi all,

6mm Hardiebacker is fine to use on the floor and is used in millions of homes in America (can you guess its the rep speaking.)

We would recommend a fast flex adhesive to put under the board and a fast flax on top as well.

Just to clarify, do you mean a flexy rapid set adhesive?

Sorry I am not 100% on actual name the notes I have from BAl is when they checked for their own records to make sure it all worked ok they recommend fast flex adhesive on the 6mm and the 12mm you can use a flexible, single part or a cement based with additives.

For Dunlop this is a 2 part rapid flexible.

Are these the adhesive brands you use?

If not I can try to speak to the other companies.
----
We have produced the 12mm Hardiebacker for use on the walls as this can fit in with 12mm plasterboard as we know most tilers will not do the whole bathroom in backer.

The 6mm has a 3mm notched bed of adhesive underneath and again ontop.

I had presumed as the 6mm boards were being advertised for floor use that they would be denser and more rigid than the 12mm boards. From the above that doesn't appear to be the case. Aquapanel provides a flexural strength figure for their board. It would be helpful to have these figures for all boards so a like for like comparison could be achieved of how rigid the boards are in comparison to each oher.

DS, I havent got that on my laptop but I will ask our technical guy and find out and post back. He doesnt work weekends do I am afraid it will be monday.

Does anyone elase have any questions I can help with?

6mm boards are, in fact, more dense than 12mm, it says so in their literature. However, I don't think it is as rigid as the 12mm.

Let me get you an exact figure from our tech guy. You may as well abuse the rep while you have me here

 

[DS Tiling]

That would be helpful Norhern, flexural strength in N/mm2 if possible.

Thanks

Saturated 8.3MPa
Equilibrium 13MPa

The conversion is 1:1 so the same figures in N/mm²

Does this help guys!

Thanks for doing that Northern. Are the figures for the 6mm or 12mm boards?

All this talk is making me nervous as i'm going to be laying 6mm hardi down on floorboards in a couple of weeks time.

You have nothing to worry about, is the first time you are doing it?

PM where you are in the country and if you want I can have a chat with your rep and get them to walk you through it. What have you used before?

 

[Fekin]

Right, for those who first lay a bed of flexi adhesive then lay the board onto the adhesive bed, then screw down, do you let the boards \ adhesive set before lumbering onto the boards to screw down or what ?

 

[DHTiling]

Yes!!!!!!!

Sorry for the late answer. The figures were requested for 6mm

That's better McKay!!!
