Smile WonderBoard Backerboard and Self-leveling underlayment

Hi everyone
i am planning to put tiles on my second stores kitchen's floor.
i have pulled out the previous vinyl floor and other wood board.
As you can see from the pictures i have uploaded, the kitchen's floor are left with slat wood(i think) and some 3/4 plywood around the exit door area.Name:  DSCN0327.jpg

current state of the floor: no squeaky sound but are not leveled

My question is, should i....

option A:
1) screw down the 1/4'' Wonderboard Backerboard around the floor
2) apply tape and cement in between the gap of the Backerboard
3) apply latex primer on the backerboard
4) apply self-leveling underlayment
5) then put the tiles...

option B:
1) use cement to seal the gap in the wood floor.
2) apply latex primer on the wood floor.
3) apply self-leveling underlayment.
4) then put the tiles....

should i put the self-leveling underlayment to the whole floor? would it be too heavy for my floor? or just the spot i needed?

i feel like the tile itself would be more durable if i self-leveling the whole floor.

or is there a better way of doing the job?

reference:
wonderboard backerboard: WonderBoard | WonderBoard Backerboard 1/4"x36"x60" | Home Depot Canada
latex primer: LevelQuik | LevelQuik Latex Primer - 946L | Home Depot Canada
self-leveling underlayment:LevelQuik | LevelQuik RS Self-Leveling Underlayment 22.7kg | Home Depot Canada

Any advice would be nice
Thank you
Phil

Lot of lookers but no one wants to deliver the bad news. Hardwood strip flooring is not a good subfloor for tile. It expands and contracts too much to be a stable substrate under your tile floor. It is a shame that someone chose to spread glue over the entire area and install vinyl as it would complicate refinishing of the hardwood. You could do an engineered floating wood floor with a tiled entryway. Otherwise, you need to replace the hardwood with a suitable subfloor (3/4" Advantech or equivalent) and then you can install backer board and tile.

Hi Czizzi
how about sanding the floor and then use Ditra underlayment?

Tile over Hardwood, a discussion at The Floor Pro Community

http://www.johnbridge.com/vbulletin/...p/t-67432.html

The above links may say things differently than I have already stated, but with the same result. It is the hardwood itself that is the weak link. Sanding, or anything else will not change the fact that it expands and contracts too much to successfully put very rigid, not flexible tile on top. Regardless of uncoupling membranes used.
