How to Resurface Concrete Driveways With Aggregate

Aggregates are crushed rocks or pebbles mixed with cement and often resurfaced onto driveways to add a decorative touch. The aggregates vary in color and size and can be partially exposed from the cement to exude the eclectic qualities of the stones. Resurfacing a concrete driveway with aggregates is a large job and requires at least two people to complete. The choice of size and style of the aggregates will be integral in laying out a suitable foundation that matches the landscape of the house. Since it is a driveway, avoid laying overly large or rigid aggregates to keep the surface smooth.

  Wash off the surface of the concrete with the pressure washer and a stiff-bristle broom to expose the stone aggregates.
