How soon can we grind/polish new concrete?
We've been asked to bid polishing the floors of a new pump station. There is only about 5,000 sq.ft. but as soon as the floors are poured, all the trades would like to get on with putting up block walls and bringing in all massive pump and pipework.
How soon could we start grinding? The floor will be 4,000psi or better mix. I would like to at least be able to hit the entire floor with the metals before everything gets turned into a massive hand-polishing job. I think we could talk them into staying off the slab for seven days. For some of the most congested areas we may even be able to get a bit more time.
