Ideally you want the floor flat and level before tiling. You could use SLC over the Hardie, or if it's flat but not level and you can live with it just crack on tiling.
To be honest 10mill across 2m isnt that far out and if the trays not level I'd be surprised if you'd even notice it, but if you really want it to be level then yes screws work as do spacers stuck together, anything that will give you a true level across and an idea of how deep to pour slc, make sure any escape routes for leveler are sealed then just poor and trowel till you cover your depth guides..Ok that sounds good. As I said though I have no experience with slc. How do I establish my levels across the floor. I hear some people use screws?? Do I just pour from the high end and push it to the low end. Any (more) help would be appreciated. thanks
