Stone tile on the floor requires a very rigid substructure. More so then ceramic tile. I have no idea what, "5/8 lp tophotch 450" is. The 1/2" ply is inadequate as a subfloor. Whether you can put stone down depends on the joist system size, spacing and span, as well as the proper subfloor setup.
To make your posts more readable it would help if you traditional English and not a texting format.

We need the joist span--joist size---species ---and spacing---The OSB was a poor choice for natural stone---Not very strong---The Amazing John Bridge Forums Deflect-O-Lator :-)

Get back with useful data--Mike---

It would help if you answered the questions asked of you. I asked you about the floors substructure on 4/23.
Still no response except, "any help" .
This dialogue doesn't work in a vacuum.

Check a deflection table with the components you have and see if it's up to the task of a stone floor. The John Bridges forum might have one.

Without knowing your deflection rate, you're just guessing. It could be an expensive lesson if you guess incorrectly.
