Exposed Aggregate patios, driveways, and walkways are decorative stone surfaces commonly used in residential and commercial landscaping. These surfaces require a coat of a new sealer to provide protection and enhancement to the substrate. This Exposed Aggregate Sealer is typically applied every 1-3 years depending on the exposure and traffic.
