So, where do you start with this seemingly intricate task, and how can you dodge the most common roadblocks? Stay tuned to our blog as we guide you through the process, helping you avoid common pitfalls and ensuring the longevity and aesthetics of your driveway.
Understanding Exposed Aggregate Concrete
Exposed aggregate concrete is a decorative type of concrete. Its top layer of aggregate – which includes materials like gravel, pebbles, and crushed stone – is intentionally made visible. This style is particularly favoured for its application in exposed aggregate driveways, not just for its aesthetic charm, but also for its slip-resistant properties.
The unique and textured look of exposed aggregate concrete is a result of the aggregate being visible on the surface, adding unmatched aesthetic value and providing an excellent grip for your feet. Don’t be fooled by its intricate visual appeal, the durability of this concrete style is surprisingly high, making it a favourite choice amongst many Melbourne homeowners.
A key element in ensuring the longevity of your exposed aggregate concrete is sealing. Applying a concrete sealer to protect the surface from stains and weathering will enhancing its appearance and extending its lifespan. The application of sealer to your driveway is a critical step that we execute with precision. We often recommend using penetrating sealers, as they offer superior protection without changing the surface’s appearance.
The process of resealing exposed aggregate is also crucial to maintain its integrity over time, ensuring your driveway continues to look its best and perform efficiently.
Importance of Sealing Your Driveway
As a protective shield, driveway sealer significantly reduces the risk of crumbling, cracks, and water damage, while enhancing the aesthetic appeal of your exposed aggregate concrete driveway. But the value of sealing your driveway stretches beyond just the visual appeal.
In our experience, concrete driveways, especially those with exposed aggregate, are highly susceptible to damage from weather conditions, vehicle traffic, and accidental spills. As a solution, our team applies a high-quality sealer that seeps into the concrete’s pores, creating an effective barrier against these damaging factors. This not only extends the life of your driveway but also minimises the need for frequent, costly repairs.
Penetrating sealer does more than just protect your driveway from physical damage. It also wards off unsightly stains from oil, grease, and other contaminants. As a result, the sealer maintains the vibrant colour and texture of the aggregate, enhancing your home’s curb appeal in the process.
Pre-Sealing Preparation Steps
Applying a sealer to your driveway is an essential step to ensure the long-lasting protection and beauty of your exposed aggregate concrete. In order to do this correctly, you need to follow specific pre-sealing preparation procedures to ensure the durability and effectiveness of the sealer on your driveway. These steps begin immediately after the installation of the exposed aggregate.
The first step to take is to thoroughly clean the surface. This involves using a high-pressure wash to eliminate any dirt and grime that may have settled on the decorative concrete. This crucial step ensures the removal of loose stones, providing a clean top layer on which to apply the sealer.

- Loose stones on the surface are removed with a broom
- We make sure the surface is fully dry before sealer application
You need to be sure to completely dry surface before the sealer application. Any residual moisture on the surface could prevent the sealer from properly adhering to the concrete. Once the driveway is sufficiently dry, you can proceed with the sealer application.
Step-by-Step Sealing Process
Once you’ve ensured a clean and dry surface, you can begin applying the sealer.
The process begins with the application of a topical sealer, typically using a ½-inch roller. The importance of the sealer can’t be overstated, as it offers varying levels of protection, aesthetics, and longevity. We prefer the topical sealer for its superior ability to enhance the colour and texture of the exposed aggregate. Not only does it provide a high-gloss finish, but it also offers robust protection against wear and tear.
Throughout the sealing process, you should apply the sealer evenly using a ½-inch roller and a pump-up sprayer. Divide your work into small sections to ensure every part of your driveway is well-coated. Once the sealer is applied, it’s crucial to let it dry according to the manufacturer’s instructions.
We recommend resealing every 12 to 36 months, depending on weather and traffic conditions. While it’s possible to undertake this task yourself, our skilled team at Smooth Concrete is always on hand to provide their expertise in using exposed aggregate.
Post-Sealing Care and Maintenance
To ensure the longevity and aesthetic appeal of your driveway, we strongly recommend regular upkeep and diligent attention.
We advise a thorough power wash every 40 days to keep your driveway spotless. Should you notice any rust stains, apply a rust remover promptly to prevent permanent damage.
To maintain the high-gloss finish of your driveway, we recommend reapplying a superior quality sealer like the Clear Concrete Sealer every 2 to 3 years. For optimal results, always apply thin coats, as it improves coverage and durability.
After the sealing process, we suggest limiting foot traffic for at least 1 to 4 hours, and vehicular traffic for a minimum of 24 to 48 hours. This allows the sealer to cure properly, guaranteeing a better finish.
Periodic care and maintenance are the cornerstones to preserving the beauty and functionality of your exposed aggregate concrete driveway. By following these steps, you can enjoy a durable and visually appealing driveway for many years.
