Applying a water-repellent sealant to finished concrete creates an internal subsurface barrier that prevents water and salt from penetrating the concrete over time. Additionally, hardening the concrete mass strengthens and protects it against degradation and other pollutants. It is perfect for exposed concrete surfaces like the outer surface of buildings, podium decks, bridge decks, marine floats, offshore platforms, sidewalks, traffic-bearing structures, runways, and sports walks because it can endure temperature stress.
