hi
client says it was done professionally with a machine as a finish but has since changed his mind and now wants ceramics.

Not really sure but if in doubt rough it up with sand paper, prime and tile.

It is probably a power floated floor like in warehouse you will have to give the floor a mechanical key and prime before tiling

[smurf21]

IF its just power floated it should be ok to just prime and tile key it if possible but if it s fully cured you aint got a prayer without a machine of sorts but if it was me i would just prime and tile using a suitable addy check some of the addy tech data to see which ones are best suited
