True. I don't really understand the reason for sealing the surface of
the concrete in the first place, unless it is maybe to avoid severe
freeze/thaw spalling of the surface. Any other reason ignores the fact
that concrete is perfectly happy being wet, and the alkali in it
inhibits rusting of most iron embedded in it.
