Minor cracking and imperfections add to the character of the finished floor. Is the basic cost for a polished concrete floor. In the early years when one talked about adding color in conjunction with polishing first it was integral colors or dry shake hardeners then acid stains crept to the forefront as it became viable to combine densifying and acid stains.
For existing floors polishing enhances their appearance by grinding the concrete down to a smooth high gloss finish. Once you ve finished grind the floor again with an 80 grit metal bonded diamond. Meaning that whatever has already been applied to your concrete floors has fundamentally changed the material and will affect coloration going forward. By now you may have gone over the surface area with 2 or 3 different grit sizes depending on the condition of the floor.
For a fairly smooth floor that requires only a few levels of grinding 3 sq. Mop up the area as you go until the floor wax is completely removed.

Grind the concrete floor using a 30 to 40 grit metal bonded diamond.
Then move up to a 150 grit bonded diamond or something finer if necessary. Color and concrete have evolved during the past decade but especially within the past year. Typically some surface preparation is required prior to polishing to remove dirt grease coatings or blemishes. A liquid densifier or hardener is applied to the concrete at this time to harden and strengthen the cement matrix between the aggregates.
If the concrete floor has wax you will need a floor wax remover.
