Thank you for your response.

The sub-floor I removed was particle board. You can imagine how bad it was
after years of water damage. The floor tiles came up with no effort.
Under that is typical thick boards used in old houses.

I guess 1 " plywood would do the trick.

Thanx


Particle board substrate eh?

do a google groups search for posts from myself and one or two other
knowledgable folks like RicoJour, Dan C, Charles Spitzer, dadiOH and a
few others, regarding this and other tile issues.

And do not under any circumstances take advice from Rudy. He advocates
using for a substrate the very crap (particle board) you're removing.
Rudy's nothing more than an unhappy homeowner whose builder screwed him
on his tile installation (which he ignorantly and vehemently defends).
In order to nurse his wounds he attempts to give tile advice here.

Go figure...
