Exposed aggregate concrete is a popular choice for driveways, patios, and other outdoor surfaces in Melbourne. With durability, slip-resistance, and aesthetic appeal, it’s easy to see why an exposed aggregate finish stands out.
But there’s a catch…
Like any concrete surface, this one can be vulnerable to damage from moisture, stains, and other contaminants. That’s why it’s important to seal exposed aggregate concrete driveway, patio or other surface to protect it from the elements and extend its lifespan.
In this article, we’ll take a look at the steps you can take to seal your exposed aggregate concrete. Whether you’re a homeowner looking to protect your driveway or a commercial property owner looking to maintain a concrete walkway, these tips and tricks will help you get the most out of your concrete surface.

Step 1: Clean the Surface
To prepare exposed aggregate for sealing, it’s important to ensure that the surface is clean and free from debris.
Start by sweeping the area thoroughly to remove any loose dirt, leaves, or debris. Then, use a pressure washer to remove any stubborn stains, oil, or grease that may have accumulated on the surface. Allow the surface to thoroughly dry before proceeding to the next step.
Once the surface is clean and dry, it is time to apply a sealer.
There are two main types of sealers that can be used: topical and penetrating.
- Topical sealers sit on top of the concrete surface and provide a protective barrier against moisture and stains.
- Penetrating sealers penetrate into the concrete pores to provide long-lasting protection against water and other contaminants.
Both types of sealers can be applied using a roller or sprayer, but it is important to follow the manufacturer’s instructions for application and drying time.
Step 3: Allow the Sealer to Dry
After applying the sealer, it is important to allow it to dry completely before walking or driving on the surface. The drying time will vary depending on the type of sealer used, as well as the temperature and humidity levels in your area. In general, you should avoid using the surface for at least 24-48 hours after applying the sealer.
Step 4: Apply a Second Coat (Optional)
If you want to ensure maximum protection, you can apply a second coat of sealer. This will help to fill any small gaps or pores that may have been missed during the first application. Again, it is important to follow the manufacturer’s instructions for application and drying time.
Step 5: Maintain the Sealed Surface
Once your surface has been sealed, it is important to maintain the surface to ensure its longevity. This includes regular cleaning with a mild detergent and water, as well as avoiding the use of harsh chemicals or abrasives that can damage the sealer.
Additionally, you should avoid exposing the surface to extreme temperatures or heavy traffic, as these can also cause damage over time.

Additional Considerations for Exposed Aggregate Concrete
In addition to the steps mentioned above, there are a few more tips and tricks that can help you get the most out of your surface. Here are some other things to think about:
Choose the Right Sealer for Your Surface
When it comes to sealing exposed aggregate concrete, it is important to choose the right type of sealer for your particular surface.
There are several factors to consider when making this decision, including the type of aggregate used, the size of the aggregate particles, and the level of traffic that the surface will receive. A professional in Melbourne can help you determine the best sealer for your specific needs.
Check the Weather
It is important to apply sealers in the right weather conditions. If the weather is too hot, the sealer may dry too quickly and not penetrate the concrete surface effectively. If the weather is too cold, the sealer may not dry at all, leaving your surface vulnerable to damage.
Make sure to check the weather forecast and choose a day that is dry and mild for optimal results.
If your surface will be exposed to foot traffic, it is important to choose a sealer that provides slip-resistance. A slip-resistant sealer will help to prevent accidents and injuries, particularly in areas that are prone to wet or slippery conditions.

Apply Sealers in Thin Coats
When applying sealers, it is important to apply them in thin, even coats. This will help to ensure that the sealer penetrates the surface effectively and does not create a thick, uneven layer on top of the concrete. A professional in Melbourne can help you apply sealers in the most effective way possible.
While it is important to seal exposed aggregate concrete surface, it is possible to over-seal it, which can lead to a buildup of sealer that can cause discolouration or other damage. Make sure to follow the manufacturer’s recommendations for how many coats of sealer to apply, and be careful not to apply too much sealer at once.
Monitor for Cracking
Finally, it is important to monitor your sealed surface for signs of cracking or other damage. If you notice any cracks or other signs of wear and tear, it is important to address them as soon as possible to prevent further damage.
