floor tile problem

I am trying to tile over a hardwood floor (wife's idea) but the tile cement is not sticking to the floor. I'm guessing I have to sand off the polyurathene to get the cement to stick. Wants it done by the weekend!

Thinset won't work in this application, you'll have to use a mastic (glue ) for tile. It should also be noted that if there's any movement in the wood, the tile will crack and pop loose as well.

Don't even try laying ceramic tile over a hardwood floor without first & properly .....installing an appropriate underlayment.

Also.....have you checked whether the deflection will even allow for ceramic tile?

My guess is your hardwood floor is 3/4" over a 3/4" subfloor which should make any deflection in the floor a non issue as long as the HW floor is nailed down solid with no buckeling in it.. If it were me I'd go over the poly'd HW floor with a 60 grit sandpaper in either a belt sander or any electric sander you have just to scuff it up real good and get any loose stuff off then I'd thinset down some 1/4" hardiebacker screwed into the floor below but that may be a drag of a job screwing into an oak floor in which case I'd buy Ditra and just thinset that down then get to tiling. MAtter of fact...forget screwing down a CBU...just buy a roll or how ever much you need of Ditra. Way easier and even better....justa bit more in materials but a whole lot less in labor...
You can pick up rolls of Ditra in the tile dept of HD.
