Penetrating sealer for uncured concrete and aggregate

[s14kev]

I just had broom finished concrete poured for a barn aisle and an exposed aggregate (pea gravel) driveway poured. I understand concrete takes 28 days to cure. I have a few gallons of Ghostshield 9500 left over I was going to use on the broom finished concrete. Ghostshield recommends I wait 28 days for cure whereas the concrete contractor recommended I seal it now. I'd rather do it now while it's nice and clean however I'm sure the manufacturer has a reason to recommend waiting. Anyone used a penetrating sealer on freshly poured concrete? I'm also wanting to seal the aggregate driveway. Is Ghostshield 9500 OK for exposed aggregate as well as plain concrete?

I used ghostshield 4500 and 8505. The outside apron was broomed finish. The difference with vrooming was that it soaked much more material than the inside. I did wait the 28 days as recommended. Concrete doesn’t cure quickly throughout the slab. Did the contractor recommend driving on it right away?
