it will depend on how much you put down and this will depend on the degree of soiling. Again as you will mainly be doing synthetic tiles without much absorbency a lot will depend on the pad that you use. An absorbent pad will leave less moisture. You will not really be selling the benefits of fast drying over something as powerful as the titan, and on a lot of the jobs that I do a faster drying time is not the benefit. If you have oxidisers in the product then you want it to stay down for longer to get the benefits from that anyway.
