From what people have observed here, it does change the appareance, and
worse, in the high wear areas, it goes in a very short time, like 6 months
or less and then creates a striking difference when the water soaks into
the high wear areas but beads on the low wear areas. You end up requiring
re-application very frequently if you want to keep an even appearance.

Ideally, you make the concrete strong enough so that it can withstand that
sort of weather on it's own. A sealer may help sub-standard concrete, for
a little while, but on good concrete, it's a waste IMHO.
