I recently built a concrete coffee table for our new home. It's 4' x 4', so it's fairly big and extremely heavy. I thought i was finished until my wife asked me to grind it down to reveal more of the aggregates. I think I will do what i'm asked to do so the question I have is will it be more beneficial to grind it down while adding water or should I just get to grinding and not wet grind it? Is wet grinding faster?

Thanks,

Steve
