Olympic / Rust-Oleum / PPG
While I have not used either product, my research shows that both Olympic Rescue and Rust-oleum deck and concrete restore, will work great on your Patio as long as all manufactory instructions are followed and the concrete has a brushed finish. Neither are designed for use on garage floors, driveways or any other areas with vehicular traffic.

Rust-Oleum deck and concrete restore
Deck & Concrete Restore is a durable coating product formulated to resurface most wooden and concrete surfaces while providing lasting protection against moisture and the damaging effects of the sun.
Designed for a variety of applications, it is the most cost effective, and environmentally conscious way to revitalize wood or concrete surfaces. Deck & Concrete Restore can be applied over most outdoor wood or concrete surfaces to achieve a new finished look free of cracks, often better than new!
