Tiling on wooden floor boarsds/concrete floor

[grumpygrouter]

I have only just come back from doing a quote. This very same issue i.e. half the kitchen is concrete and the other half is floorboards. I can't see the concrete/wood join because the floor is covered in laminate. However, I thought I would Hardibacker the whole area, but have found that Hardibacker is not designed for laying onto concrete...which I thought is a bit strange. I got this info from the faq on Hardibacker. So my question is Can I use Hardibacker? also CJ mentions plug/screw on the concrete side.......what is plug/screw? Cheers Sean

Drill the concrete and then rawlplug it then screw the boards to this! It can be done as I have done it myself but it can take time! an SDS drill is essential here I would say!
