Hardy backer 12mm. Is it possible to dot and dab using thickset adhesive?

[inspectapart]

Hi, I just need some help with fixing 12mm hardy boards. I have ixed the two walls that are studded using drywall screws....seems to be O/K so far. But I have to cover an old brick wall also. I took of the high spots and primed it using ULTRA PRIME FLEXIBLE adhesive DILUTED 3 TO 1. I WAS HOPING TO DOT AND DAB THE BOARDS ON WITH ULTRA PRO RAPID ADHESIVE. What do you think?
The wall is pretty uneven but plumb. 1/2" of dab would allow me to level up I think.
The alternative is to battern out and that would mean a lot of packing out the batterns to get it level.
Hope this makes sense.

Hardibacker do not advise it..

You can use a marmox type board though and D&D that onto the walls with Adhesive, and then mechanical fix as well through where the dabs are.

If I use Marmox, Which adhesive should I use/ It would need to be a thickset type to get over th uneaveness of the wall

Haven`t picked the tiles yet but they will be Just ordinary 9mm wall tiles. No great weight to them.

Why not use plasterboard and tank it if it's within the shower area.

I thought backerboards would be easier...no plastering etc.

If you use plasterboard, you do not need to plaster it. Just use the bare boards.

why no need to plaster? unless I tank it?

O/K, if its that easy why bother with backerboards at all??

I only use backerboards on floors. The good point of a backerboard is that it doesn't deform if it gets wet, tanked plasterboard will get you the same result.
