My brother recommended this. I used it on our patio & stamped concrete around the in ground pool. The patio pavers (black & gray) didn't have that much color (only 2 years old). The black especially instantly looked brand new! The black & gray popped with color! We are very impressed & happy with Foundation Armour! Hopefully the colors stay, as we used another sealer from the company we purchased the pavers through last year & the colors faded rather quickly.
