I did a search and I see wait 30 days and do it right after it was poured.

If you are confused about some people saying to cure it immediatly and some
saying wait 30 days, it's because they were talking about two different
things.
After the concrete is poured and finished they sometimes put a curing
compound on it, which is often called a sealer.
This stops the moisture from evaporating, thus making the concrete stronger.
You do not want this on your floor if you are going to put an epoxy finish
on the concrete.
Check with the manufacturer and see how long they suggest you wait before
applying the finish.
