Hi  We have a condo marble lobby floor that we have refinished each year for the past 3 years. The management would like us to convert this to a maintenance program. Most of what we do is full restoration and relatively little maintenance  We just finished the floor in October and the floor is showing significant wear in spots (e.g. in front of elevators and desk, and hardly scratched in others). I have a pretty good idea of what to do to get the whole thing back up to speed, but then, assuming I can stay on top of it so that the floor only needs regular polishing, what are people's experience as to polishing regularity?  My knee jerk is to polish the worse areas every month, the best (hardly touched areas) every 6 months and in between ears every quarter. Is it advisable to do more than that? Even more than once per months or the worse areas?

Second, if an area that has some gloss to it is re-polished, is it safe to assume less than 2 minutes per 10 sf area?  

Third, I have not worked with crystallizers on a regular basis and have seen what extensive crystallizing does to floors, but is it safe to crystallize every so often just to give the floor some pop?

Any suggestions would be much appreciated. 

Thanks,

Baird
