Do I tank aqua panels or Hardie boards. - Tile Advice

[Craftycocknet]

Thanks, it raises some good points.

How would using the cement board damage the tiling if water was for some toreason get through.?

So if you tanked it, other than not being able to take as much weight and the cutting and being a heavier product etc, there would no other other disadvantages to using it? For the future strength of the tiled wall I mean.

Thanks

Get some of their 'board adhesive' it's a tube of white polymeric adhesive. You can seal fastener heads by smudging a blob over them. The really correct way is to tape the joints so a roll of jointing tape should suffice. You can bond that too with the tube adhesive. Just be careful to achieve a good bond. Small disposable notch trowel is ideal for this.
Screws, i just use standard screws. And galv washers.

Cement boards have damaged tile installations by allowing water to damage the studs and floor boards, twisting and shifting the boards which damages the tiling. Same could happen with other boards IF they aren't installed correctly!

I take it you mean insulation board? While you are in CTD, get some ardex wp. Mix a small amount at a time and go over the washers/screws, with a filler knife, plasterers float or even an old paint brush.
Don't forget the joins in the boards and floor to wall joins will need taping and tanking.
