Aggregate Concrete

Maintenance Tips for Exposed Aggregate Concrete

With the right care, exposed aggregate concrete will look great and perform well for decades. Follow these straightforward maintenance steps:

Reseal every 2–3 years

Resealing protects the surface from UV damage, staining, and moisture penetration. The frequency depends on traffic levels and exposure.

Clean with pressure washing

A regular pressure wash removes built-up dirt, algae, and surface grime without damaging the aggregate or sealer.

Avoid harsh chemicals

Strong acid-based cleaners can strip the sealer and damage the cement matrix. Use pH-neutral cleaning products.

Repair cracks early

Small cracks addressed promptly prevent water ingress, which can cause the crack to grow over time — particularly during freeze-thaw cycles.
