Tilling on a wooden/Concrete floor

[tkeeber]

Hello all,

I am currently doing up my kitchen and the next job is tilling my floor.

The problem is have is that half of my kitchen is floor boards, and the other half is concrete. There is a small ridge where the floor board and concrete meet which varies in height - slopping down towards one wall. The maximum ridge about 8mm - but only that big in a small area of about 10 cm across.

So my question is; what is that best way of dealing with this floor board/ concrete combination? My initial thought was to lay ply down to make the floor completely flat (get rid of the ridge) but then would i be able to lay the ply on the concrete as well as the wood?

Any help/advice would be very much appreciated.

Use Knauf aquapanel cement board across both floors, adhered with rapid set flexible and screwed down, use the rapid set adhesive under the cement board to level both floors and take up the difference
