Can you grout over grout

Grout bonds mostly to the tiles, less so to itself. If you dig the grout out, try to do it at a 90 degree angle to the "proper height" grout, this will give you the best adhesion for your patch.

However 48 hours is right on the cusp of where I might try to fill it in. Typically grout takes a few weeks to fully cure, but is ready to seal after 2 or 3 days.

That says to me that you might still get the new grout to bond to the old. I know there are cases where a homeowner might accidentally scratch the grout, in general, the tile mechanic doesn't always scrape up all the grout, before fixing something like that.
