What to know about cleaning exposed aggregate

Exposed aggregate concrete has stones showing at the surface. Too much pressure can loosen stones at the edges, and the surface looks best when cleaned and resealed.

Avoid: High pressure at edges and cracks, which can pop out aggregate.

How often: Clean yearly; reseal every 2-3 years.

Is it time for concrete sealing for exposed aggregate?

  • Water soaks in instead of beading
  • Stamped concrete looks faded and dull
  • Surface flaking or spalling has started
  • Stains soak in quickly

Why it gets dirty

  • Old sealer worn away by sun and traffic
  • Freeze-thaw cycles and deicing salts
  • Unsealed concrete absorbing oil and water

Easy upkeep between cleanings

  • Do the water test: sprinkle water and see if it darkens the concrete quickly
  • Keep traffic off a newly sealed surface for the time on the label
  • Avoid deicers that contain ammonium nitrate or ammonium sulfate

Common mistakes to avoid

  • Sealing dirty or damp concrete, which traps stains and turns cloudy
  • Slippery finishes without an anti-slip additive
  • Applying too thick a coat, which peels

  1. Clean the concrete thoroughly
  2. Treat stains and let the surface dry
  3. Repair cracks where needed
  4. Apply a penetrating or film-forming sealer

Do you use high pressure for concrete sealing for exposed aggregate?

For exposed aggregate: usually 1,500-2,500 PSI with a surface cleaner. What we avoid: high pressure at edges and cracks, which can pop out aggregate. We keep the pressure even and controlled, with the right tools for the surface.

Is concrete sealing for exposed aggregate safe for my plants and pets?

We pre-wet plants and lawns, keep cleaning solutions diluted to what the surface needs, and rinse landscaping again when we finish. Keep pets and children inside until surfaces are rinsed and dry.

How often should I schedule concrete sealing for exposed aggregate?

Clean yearly; reseal every 2-3 years. Shade, nearby trees, humidity and heavy traffic mean more frequent cleaning; sunny, dry spots can go longer. Our free cleaning frequency tool gives a recommendation for your climate.

What if it rains on the day?

Light rain doesn't stop most washing, but heavy rain, high wind, lightning and freezing temperatures do, and sealers and stains need dry weather to cure. If the weather isn't right, we reschedule at no charge. Our work is backed by a satisfaction guarantee.
