Default To OSB or Not to OSB

We saw some porcelain tile we liked, but it's ok to use concrete board over OSB? I'm not sure why the Home Depot guy was so insistent that that was a bad idea.

Thanks,

Because it's a bad idea. Not saying your installation WILL fail, but
the chances of success using OSB will be significantly lower rhan with
plywood - and just putting plywood over the OSB is not quite as
effective as replacing the OSB and doesn't raise the floor level as
much.


I'd talk to a real tile guy, not the Home Depot guy.
