Priming of floorboards before fixing cement boards?

[The Legend; Phil Hobson RIP]

do you mean the old style floorboards Phil, as opposed to t&g chipboard flooring?

Doug, I use this method on small areas only, 9mm wpb ply screwed at 6" centres, then Hardie board 6mm glued and screwed using Keraquick with latex plus. Then tiles fixed with Keraquick with latex plus, on T&G floorboards or chipboard (providing no deflection)

How thick are your floorboards?

They are 18mm T&G traditional floor boards, the area is less than 3sqm and I have screwed all the bords down in addition to the original nails.

I see your reluctance to use 28mm screws then, they'd have been fine if you had 22mm T & G
