Installing 1/2' thick ceramic tile over oak floor
A few weeks ago I asked if I could tile over oak floor area in my
foyer 4'X15' and everyone suggested using some kind of underlayment. Recently my wife and I picked out a tile that is 1/2" thick and is 11 3/4" X 11 3/4". This tile looks a lot more beefy than ordinary tiles and of course costs twice as much. Now the problem is because it's 1/2" thick it would be a problem heightwise even if I used a 1/4" backerboard. So my question is will this tile be less likely to have problems if I go over the wood floor because it's so thick even if I screwed down the floor at every joist. By the way my combined subfloor and hardwood thickness is 1 1/2". |

If it's in decent shape I would be very hesitant to cover it at all, or at least to permanently marr it up. |

I removed the old tile and 1/4" plywood that was on it originally. Structurally its fine. We have oak floors throughout the first floor, but we liked it better to have tile in this entryway because it was easier to clean plus the tile floor continued into the kitchen, which I am remodeling. |

I'd just sand the finish rough, seal it (in case any water gets under there) and just tile on top. Sounds like you have a secure base already... But I'm just a handyman, so take my comments with a pinch o' salt! |

On the advice of a tile pro, I put down ECB membrane, which is an antifracture membrane, and I tiled over that. I had exactly enough membrane to do both kitchens, and skipped a small area that would be covered by cabinets. I tiled and grouted, and all the grout lines cracked in the small areas where I hadn't used the membrane, in less than 24 hours. JK |

If the oak floor is roughed up a bit and the joists are not spaced too far apart and there's no flexing between them, you should be fine. Someone mentioned sealing the sub-floor first, but I disagree. A sealer may interfere with the adhesive you use for the tile. |

Ever had a squeeky wood floor?? Especially in a high traffic area, you want it strong as possible. To do it properly, remove the oak, then you'll have laths which are over the floor joists. Put 1/4 plywood, then a thinset, then 1/4" Wonderboard (or whatever to meet the desired other flooring height), then mortar and tile. Be sure to use screws to secure the Wonderboard throught to the joists. You could even remove the laths, then you could nearly match your existing flooring. You'd need minimum 1/2" plywood, and 1/2" Wonderboard. That would be a rock solid finish. samurai. |

Where are you? 1/2" plywood is NOT enough under 1/2" wonderboard, 5/8" minimum for joists on 16" centers. If you need to keep height down, use 1/2" ply over the joists but first put 3/4" between the joists level with the joist top, with 2x2" attached to the joists under the ply, supporting the edges, then install the 1/2" ply subfloor, add the wonderboard then you have a solid base. |

Also the Hardi or Wonderboard does not need to be screwed to the joists. Ya want proper? Place an actual mortar bed over the sub-floor for a tile base. |

Hardibacker over that plywood. I figured it would better to put 3/4" plywood rather than 1/2" plywood plus 1/4" hardibacker, right or wrong? |

With the plywood there's chance of flexing, the backerboard adds density which helps to eliminate flex problems. You'll sleep better. :-) I posted this link the other day. It's a short but IMHO extremely important read. Check it out. http://www.ttmac.com/deflection_limitations.htm |
