   try Sonneborn SL-1.  It is a self leveling urethane, and according to their website, intended for your purpose.

   The concrete wasn't cured enough (obviously).   SL1 is the ticket.  You see it a commercial jobs (like shopping center flat work) all the time.

   A new concrete guy I'm getting ready to start with said he has a "green blade" that allows him to cut control joints in fresh concrete.  Anyone know anything about that?  Doesn't really make sense to me.  The problem is that the pieces of aggregate chip out.

   you really need to cut the joint has soon as you can walk on it. A slab can crack overnight.

   Know what a "green blade" is?  Maybe a diamond blade with none of the curf cuts in it?

   might check the Norton site...   I don't know the difference in blades I have green, cured, asphalt blades ect... they all look about the same... green might be a finer grit...  but then i buy all my blades off ebay  .... where i think they call em whatever they think will sell

   There are saws designed to cut concrete without chipping. Recently one of the local concrete contractors bought a new saw to cut some concrete a few days after it was poured and it was without chips.
