How to Care for Exposed Aggregate Concrete

Exposed aggregate concrete brings texture and character to outdoor spaces, and it does not need a complicated care routine. Regular sweeping, prompt attention to spills, and occasional washing help limit grime and staining. A few precautions also reduce wear from weather, equipment, and de-icing products. Whether you have a patio, path, or driveway, these practical steps can help you maintain the surface and spot small issues before they become harder to address.

Clean Gently and Regularly

Sweep leaves, soil, and grit off the surface before they build up. For routine washing, use a garden hose and a stiff-bristled, non-wire brush with water and a mild detergent. Work in manageable areas, then rinse thoroughly so soap and loosened dirt do not dry on the concrete.

For stubborn grime, test your cleaning method on a small, inconspicuous patch first. Avoid harsh acids and aggressive scrubbing, which can damage the cement paste around the stones. If you use a pressure washer, choose a moderate setting, keep the nozzle moving, and follow the equipment and concrete-care guidance to reduce the risk of surface damage.

Deal With Spills Quickly

Blot oil, grease, or other liquid spills as soon as you can. Avoid spreading them with a broom or hose before absorbing the liquid. Then clean the area with a suitable concrete cleaner or mild detergent, following the product instructions and testing it in a discreet spot first.

Remove food scraps, wet leaves, and plant debris promptly, especially in shaded areas where surfaces may stay damp. These materials can leave marks or encourage slippery buildup. Use a plastic shovel or a suitable outdoor broom to clear debris without scraping or chipping the concrete.

Protect the Surface Seasonally

In freezing weather, use a plastic shovel to clear snow and avoid metal blades that could scratch the surface. Choose de-icing products carefully; some can harm concrete, particularly when it is relatively new. Check the product label and your contractor’s care instructions before applying anything.

Keep heavy planters, furniture, and equipment from scraping across the finish. Use protective pads where practical, and move items by lifting rather than dragging. Watch for water that repeatedly pools on the surface. Persistent standing water may point to a drainage issue that needs attention.

Check for Wear and Sealing Needs

Look over the concrete periodically for cracks, loose stones, flaking, or areas that remain slick after cleaning. Small changes can help you decide whether a simple wash is enough or whether professional advice is sensible. Avoid filling cracks with a random repair product; the right material depends on the damage and the existing surface.

Sealers can help protect some exposed aggregate surfaces, but they are not one-size-fits-all. Ask the installer what was used, when resealing may be appropriate, and which products suit your concrete. Applying an incompatible or poorly prepared coating can change the appearance or create a slippery finish, so follow the surface-specific guidance.

A little routine care goes a long way: sweep often, wash gently, clean spills promptly, and check for changes as seasons turn. When you are unsure about a stain, crack, or sealer, get advice before trying a stronger treatment.
