I'd keep the slump of the concrete to 5" or less, and I'd cut the saw joints just as soon as it was finished.

Now that I know "All concrete will crack". What can I use to fill/seal the cracks in my slab before I apply the finish coating? I'd also like to fill in the saw/expansion joints prior to coating so any thing with steel wheels or small wheels won't tend to hang up when rolled over these areas. Any advice is appreciated.
