I have an existing hardwood floor that I want to tile over (it's not in good condition). Can I put cement board then tile directly onto the hardwoods or do I need plywood on the hardwoods then cement board then tile? I don't want the floors to be 2 thick in addition to the hardwoods.
Hillbill gave you good advice. I went to the site he recommended. It's straight up. I would add this; what you're looking for when you're done with the cementatious board is level. And, screws are better than nails on a wood floor.
Can you explain better? What do you mean when you say the hardwood is not in good condition? Uneven?Decaying?Quick answer if the hardwood is either, youre better off taking it out and starting with a good base.
Nailing could be problematic. Nailing hardwood is done at an angle and the hardness of the cement board may cause the nails to deflect. Try it and see if it works.
