Benefits of Sealing Exposed Aggregate
Cleaning Exposed Aggregate
Prep the surface by pressure washing and dirt and grime. If needed, use a cleaner that is specific to any stains. For example: use a Rust Remover to remove rust or a Cleaner Degreaser to remove oil spills.
Always wear safety glasses to protect yourself. After cleaning, you need at least 2 days of dry weather before continuing.
Sealing Exposed Aggregate
Apply a Solvent Based Acrylic Sealer. These sealer types can be used on exposed aggregate with excellent results. Using a 1/2″ roller, start applying the sealer at the far end making sure to not step in the sealer. The sealer should be applied at the manufacturers spread rate. This is typically 100-150 sq. feet per gallon. Apply sealer quickly to avoid any over laps. Let sealer dry for 1-4 hours. If the sealer did not dry evenly, apply a second coat to even out the appearance.
Depending on your exposure to the weather and traffic, Exposed Aggregate should be sealed every 12-36 months.
