travertine on terrazzo

[ruairi mac]

Hi folks.
Customer rang this morning to ask if i.would look at a floor for her. She says it will be travertine tiles to be layed over an existing terrazzo floor. I think im right that any natural stone floor now has to be put down with an anti fracture membrane, but is there any specific prep needed for the terrazzo? Thanks in advance.

I won't tile over tiles. I can't guarantee the job.

Decoupling membrane down with grey SPF rapid, tiles down with a SPF rapid white adhesive.

If you take up the Terrazzo you will need a fair amount of slc if it was bedded onto sand/cement.

Only on heated screed according to BS5385 although given your substrate I still would personally.
