Re: 42" Pompeii in S. Louisiana
Moot point now, but those timelines are a general guide. There are always variables that will effect cure time, and waiting longer to pull the form won't damage the concrete like doing it early.
That said, what you have to fix is no big deal. Just make a slurry with portland and an acrylic admix (arcyl 60 or quickcrete) and build it out. Let it cure 24 hours before wetsanding.
I blew a corner out on a watertable piece (a chunk about 3/4") and built it out with a clay-like slurry. It bonded great and sanded out nice...nobody will ever know, except me.
