I'm in the planning phase of putting down a tile floor in our kitchen(approx 24*12) and have a few questions. I have done some tiling(backsplashes and above a shower), but never a floor.
First, I I have a 3/4 in plywood floor covered by 1/4 in Luan(leftover from the prior vinyl floor). This is in relatively good shape with only a few small areas where there is paper or glue stuck down from the vinyl.
The floor is not perfectly even ,with a few places where bowed floor joists
cause a 'rise' in the floor (maybe 1/8 ")?
I'm trying to decide if I should use cement board, hardi backer, or one of the newer 'roll' type underlayments, such as Schluter-DITRA (http://www.schluter.com/6_1_ditra.aspx
I'm a bit leery of using this new stuff, but it would make the job easier (although with something like this easier may NOT be better, if I end up with cracking tiles in a year).
Has anyone used any of this new 'roll type' underlayment for tile?
Any personal recommendations on cement or hardi?
Secondly, I'm debating if I need to use floor leveler or not?
As I said I have a few areas where due to floor joist uneveness, I have some slightly raised areas.
DO i have to use floor leveler?
Third, I've been told and read that you can you either thinset for setting tiles (12*12) OR a ready to use mastic adhesive.
Again, I don't want to shortcut and cause myself more grief later
Thx in advance
