Exposed aggregate surfaces represent both an aesthetically pleasing and robust enhancement for outdoor environments. Whether your property boasts an exposed aggregate patio, driveway, or pathway, the preservation of its impeccable allure demands meticulous care and consideration. Within this extensive resource, we will delve into crucial cleaning recommendations, providing insights on how to maintain the splendor and lasting quality of your exposed aggregate surfaces, particularly focusing on how to care for exposed aggregate driveways.

Understanding Exposed Aggregate

Before delving into cleaning tips, let’s briefly understand what exposed aggregate is. Exposed aggregate is a special kind of concrete that shows the small stones or pebbles inside it. People like to use it outdoors because it’s not slippery. It gives a natural and rustic look. This type of concrete creates a textured and colorful surface that can make outdoor areas look both attractive and safe to walk on.

Cleaning Your Exposed Aggregate Surface

To keep your exposed aggregate surface looking its best, follow these essential cleaning tips:

  1. Regular Sweeping: Start by removing loose debris, leaves, and dirt from the surface using a broom or leaf blower. Regular sweeping prevents these materials from embedding themselves into the surface, making it easier to clean.
  1. Pressure Washing: Periodically, use a pressure washer to clean your exposed aggregate surface thoroughly. Adjust the pressure to avoid damaging the aggregate. A pressure washer effectively removes dirt, stains, and moss.
  1. Mild Detergent: When dealing with stubborn stains or oil spills on your exposed aggregate surface, you can effectively tackle them by creating a mixture of mild detergent and water. Apply this mixture to the affected areas and use a stiff brush to gently scrub away the stains. Afterward, rinse the surface thoroughly with clean water to ensure that no detergent residue remains. It’s important to steer clear of harsh chemicals as they can potentially damage the aggregate and compromise the surface’s appearance.
  1. Sealing: Consider applying a concrete sealer designed for exposed aggregate surfaces. Sealing not only enhances the surface’s appearance but also provides protection against stains and UV damage. Follow the manufacturer’s instructions for application.
  1. Weed Control: Vigilance in monitoring weed growth between the exposed aggregate is crucial to maintaining the surface’s integrity. Regularly inspect the areas for any signs of weed intrusion, and if you spot weeds, take prompt action to remove them either by hand or with the use of a weed killer. This preventive measure not only preserves the surface’s appearance but also prevents weeds from compromising the stability of the aggregate.
  1. Avoid Deicing Salts: In cold climates, avoid using deicing salts on exposed aggregate surfaces. These salts can damage the concrete and compromise its appearance. Instead, use sand for traction in icy conditions.
  1. Regular Maintenance: Perform routine inspections of your exposed aggregate surface to identify any cracks or areas that may require repairs.

Tips for Preventing Damage

Cleaning Tips

In addition to cleaning, here are some preventive measures to protect your exposed aggregate surface:

  1. Use Doormats: Strategically placing doormats at entry points is a practical measure to minimize the accumulation of dirt and debris on your exposed aggregate surface. By doing so, you create an effective barrier that captures and prevents outdoor elements from being tracked onto the surface, thus reducing the need for frequent cleaning.
  1. Furniture Protectors: Employing furniture protectors under the legs of your outdoor furniture is a smart practice to safeguard your exposed aggregate surface from potential scratches and indentations. This simple yet effective measure ensures that the surface remains smooth and unmarred, preserving its aesthetics and integrity.
  1. Avoid Heavy Vehicles: It’s best to avoid leaving large vehicles parked on your exposed aggregate driveway for extended periods of time since this can put undue strain on the material and could cause damage. You may preserve the driveway’s aesthetic appeal and structural integrity by taking this precaution.
  1. Regular Sealing: The look and protective qualities of your exposed aggregate surface can be maintained by routinely reapplying a concrete sealer every few years. The lifespan of the surface is increased by this protective coating, which also improves its aesthetics and protects it from UV rays and spills.
  1. Proper Drainage: Make sure your exposed aggregate surface has appropriate drainage capabilities to keep water from building up and perhaps causing erosion in order to protect it. The stability and aesthetics of the surface are preserved by proper drainage, which makes sure that water is adequately channeled away from the surface.

DIY vs. Professional Cleaning

While many homeowners can effectively clean their exposed aggregate surfaces using the tips mentioned above, some may prefer to hire professionals for more extensive cleaning and sealing. Professionals have the expertise and equipment to tackle tough stains and ensure thorough cleaning. Consider your surface’s condition and your level of comfort with DIY cleaning before making a decision.


Exposed aggregate surfaces are not only visually striking but also resilient. With proper cleaning and maintenance, you can enjoy the beauty and functionality of your exposed aggregate patio, driveway, or pathway for years to come. By following these essential cleaning tips and preventive measures, you’ll keep your outdoor space looking its best and ensure its longevity.
