Rust-Oleum RockSolid Penetrating Concrete Sealer seals and protects bare concrete and masonry surfaces (including landscaping blocks and concrete pavers) from the damaging effects of water, chemicals and UV light without changing the appearance of the concrete

This water-base formula penetrates deeply into and reacts with the concrete to form a protective barrier beneath the surface to keep water out, protect against stains and extend the life of the concrete surface
