We have yellow tongue throughout our house, as our house is raised. We will be getting 19mm solid timber flooring throughout main areas and tiles in wet areas. We would like to keep the levels of the flooring as even as possible so were thinking that we would put 6mm cement sheet down, and then 4mm cement sheet. This plus tile height makes 18mm. Add glue etc to both timber and tiles and they both should be roughly the same height - Does this sound right?
Also, when putting the cement sheet down on the yellow tongue should we use glue (as well as screws obviously)? And if so, what type? Liquid nail which is quite rigid or something flexible?
Actually, thinking about it - if we use glue to put the cement sheet on the yellow tongue and also between the two layers of cement sheet than maybe we should use two 4mm cement sheets

There's a 9mm tile underlay at the plaster shop, but he said around $100 a sheet and we'd need 8 - I dont want to pay that
