I have ripped out old ceramic tile from a half bath in my 100 year old house so that I can lay a new ceramic tile floor. Under the ceramic tile was a subfloor which I believe is made of cement board, but it is damaged in some places and also has the old adhesive stuck to it. Should I remove this, and if so, any suggestions on how to do so? Or can I simply lay another layer of cement board over this older one? Also, I can see the original hardwood underneath of this subfloor. Is it a bad idea to lay ceramic over hardwood floors? There is basement underneath. Thanks for helping out an unexperienced tiler...

i would remove it.

use prybars and hammers and a stiff scraper if needed.

the cement board will come up in pieces.

after the cement board is up scrape adhesive used as needed until you get it down to the hardwood.

sweep and/or shopvac clean.

install new cement board or schluter ditra (superior to cement board and performs better).


There are two ways to do any job. The right way and the wrong way. Do it right everytime.

The hardwood flooring can present a problem for tile as the slats can move independent of each other and the movement if severe can transmit up through the cement board. I dont remember if Ditra warranties going over hardwood, they may, but I know the Tile Council of America makes reference to it being a bad idea in their handbook. Removing the wood and replacing it with 3/4" underlayment plywood (not CDX)would be ideal. Going over it with 1/2" ply would work in most instances but no guarantees. The additional height, plus the cement board and tile may be prohibitive.
