How to Clean and Maintain Exposed Aggregate Concrete

One of the biggest perks of exposed aggregate concrete is how easy it is to care for. But a little regular maintenance goes a long way in keeping it looking great and slip-resistant. In this guide, we break down exactly how to clean exposed aggregate concrete and protect your surface, so it keeps turning heads for years to come.

Simple Habits That Make a Big Difference

When it comes to exposed aggregate maintenance, consistency is key.

For most homeowners, routine cleaning doesn’t need to be complicated. A simple sweep every week helps remove loose dirt, leaves, and debris that can build up over time. If left sitting, this debris can trap moisture and lead to staining or surface wear.

Hosing down your concrete every couple of weeks is another easy win. A quick rinse helps wash away dust and grime before it has a chance to settle into the textured surface. This is especially important for driveways and pathways that see regular foot traffic.

The goal here isn’t perfection, instead prevention. A few minutes here and there will keep your concrete looking fresh without the need for constant heavy cleaning.

Bringing Your Concrete Back to Life

Even with regular upkeep, your concrete will occasionally need a deeper clean.

Pressure washing is one of the most effective ways to restore exposed aggregate. It removes built-up dirt, stains, and organic matter that sweeping alone can’t handle. Just be sure to use the right pressure setting, too high, and you risk damaging the surface.

For tougher stains like oil or grease, a mild detergent mixed with water can do the trick. Apply it with a stiff broom, scrub the area, and rinse thoroughly. Avoid harsh chemicals, as they can affect the finish and reduce the lifespan of your concrete.

Done correctly, a deep clean once or twice a year will keep your surface looking as good as the day it was poured.

The Key to Long-Term Protection

If there’s one step that makes the biggest difference in exposed aggregate maintenance, it’s sealing.

Sealing your concrete protects it from stains, moisture, UV damage, and general wear. It also enhances the natural look of the aggregate, bringing out the colour and texture that make it stand out in the first place.

At Dalmatian Concreters, sealing is considered an essential part of the process, not an optional extra, because it helps extend the life of your surface and maintain that “just poured” finish.

As a general rule, exposed aggregate should be resealed every 1-2 years, depending on traffic and exposure to the elements. High-use areas like driveways may need more frequent attention to keep them protected.

Avoiding Damage and Prolonging Lifespan

Looking after your concrete isn’t just about cleaning, it’s also to avoid unnecessary damage.

Try to prevent heavy impacts or dragging sharp objects across the surface, as this can cause chips or scratches. Be mindful of oil leaks from vehicles, as these can stain if left untreated.

It’s also worth keeping an eye on weeds or moss growing between joints or edges. These can hold moisture and gradually affect the integrity of the surface if left to grow.

The good news? Exposed aggregate is designed to be tough, weather-resistant, and long-lasting. With the right care, it will handle daily wear and tear with ease.

When to Call a Professional

While most maintenance can be handled yourself, there are times when calling in the professionals makes sense.

If your concrete is heavily stained, looking dull, or hasn’t been sealed in years, a professional clean and reseal can completely transform the surface. It’s also the safest option if you’re unsure about pressure washing or using the right products.

A professional service ensures the job is done properly, from thorough cleaning to applying the right sealer for long-term protection.

Exposed aggregate concrete is one of the most practical and visually appealing finishes you can choose. With just a bit of regular care and the occasional deep clean, it will stay durable, safe, and looking great for years.
