This product contain Silane-Siloxane which will, as I understand it, help prevent water from penetrating the stamped concrete.
This product went on easy with a sprayer, clear, and dried to a natural, non-slippery finish. Any water applied to this finished walkway, now beads up and appears not to penetrate.  This should help prevent any spalling when the temperature drops below freezing this coming winter.
The products been down about a month.  We will see in the spring how well it helped to slow down any winter damage.
