If it were mine, I'd reinforce it with 10 x 10 wire mesh or either use fiber in my concrete (whichever one was the cheapest). 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.
