As long as they are hairline cracks with no deflection upward, you should be OK. If there is movement up, you are kinda screwed.

You might try a roll crack isolation membrane like Ditra if you really want to make sure. I've never used it and I assume there is a tiny bit of learning curve but the pros really like it.

I don't like to skimp when it comes to tiling. It's too f-cking hard and the materials can add up. There are people like the Tile Council of North America and ANSI who test this stuff and write the standards.

I usually start a thread here to let some pros take a gander at my scheme:

Nope. People stopped having vapors with the demise of the Victorian age. OffWithTheirHeads Mar 2014 #4
