Dura-Color Hardeners
Dry-shake Color Hardeners come as powders that are hand broadcast onto the freshly placed concrete and then worked into the surface with a float or trowel. Proline's Dura Color Hardener is a uniform, streak-free concrete color hardener that's durable enough for high traffic areas. In addition to adding color to concrete, it makes a great base for stamped concrete. Available in 42 beautiful colors.
