How to Resurface Overexposed Aggregate Concrete
Concrete surfaces with exposed aggregate are firm and look good. But over time, it can lose its shine because of weather and ageing. Simply resurfacing over exposed aggregate concrete can make it look original and compelling without spending a lot of money. This guide by Ready mix Concrete suppliers in Australia will explain step-by-step instructions for resurfacing over exposed aggregate concrete and making sure that you get professional-quality results.
Why Resurfacing Over Exposed Aggregate Concrete Is Essential
Exposed aggregate concrete is usually known for its unique texture and visual appeal and is often used for driveways, patios, and walkways. Gradually, elements like heavy traffic, sun exposure, and moisture can cause it to crack, cracks, discolouration, and surface erosion. Resurfacing helps:
Restore the original worth of your concrete surface.
Improve durability and protect it from future damage.
Save money compared to complete concrete replacement.
Tools and Materials Needed to Resurface Exposed Aggregate Concrete
Before beginning the project, collect these essential tools and materials:
Pressure washer
Concrete resurfacer
Bonding agent
Trowel or squeegee
Protective gear (gloves, goggles, mask)
Edging tool
Decorative concrete sealer (optional)
Step 1: Check the Condition of the Concrete
The first step in resurfacing over exposed aggregate concrete is considering the surface’s condition. Look for:
Cracks, chips, and holes
Discoloration or stains
Signs of structural damage
If the surface is badly damaged or unstable, and if you want expert advice on whether resurfacing is the best solution or replacement is necessary, directly consult with concrete suppliers.
Step 2: Clean the Surface Thoroughly
A clean surface is required for a successful resurfacing project. Use a pressure washer to remove dirt, grease, and loose debris. For tough stains, you can use a degreaser or concrete cleaner. Before moving to the next step, always make sure the surface is dry.
Step 3: Repair Cracks and Imperfections
Permanently repair any visible cracks or holes before applying the resurfacing material. Use a concrete repair mix and a trowel to fill these imperfections. After applying the repair mix, smooth the surface and allow the repairs to cure as instructed by the product manufacturer.
Step 4: Apply a Bonding Agent
Applying a bonding agent helps the resurfacer adhere appropriately to the existing surface. Follow the product instructions to spread the agent across the concrete evenly. This step is essential in ensuring a long-lasting finish.
Step 5: Mix the Concrete Resurfacer
By following the manufacturer’s guidelines, mix the resurfacing material. Use a bucket and a drill with a mixing paddle to ensure a smooth, lump-free mixture. To avoid the mixture setting, work in small batches before you apply it.
Step 6: Apply the Resurfacer
Finally, you can apply the concrete resurfacer. Follow these steps:
Start at one corner of the surface.
Pour the mixture and spread it evenly using a squeegee or trowel.
Keep the thickness, usually around ¼ inch.
Use an edging tool to create clean lines along borders.
Work fast and carefully to stop the resurfacer from drying unevenly.
Step 7: Add Decorative Finishes (Optional)
Consider using decorative elements to make your resurfaced concrete more attractive.
Coloured concrete company experts recommend:
Adding coloured aggregates or pigments for a custom look.
Stamping patterns to mimic stone or tile designs.
Step 8: Allow the Surface to Cure
Proper curing is necessary to ensure durability. Keep the surface safe from foot traffic, rain, and direct sunlight for at least 24-48 hours, depending on the resurfacer’s drying time. Follow the product instructions for exact curing details.
Step 9: Seal the Surface
To improve durability and prevent stains, a concrete sealer adds a protective coating. Choose a sealer designed for decorative concrete driveways or exposed aggregate surfaces. Apply it evenly with a roller or sprayer, and let it dry completely before use.
Tips for Maintaining Your Resurfaced Concrete
To maintain your resurfaced concrete in perfect condition:
- Wash it regularly with mild detergent and water.
- To protect it, reapply the sealer every 2-3 years.
- Avoid using harsh chemicals or metal shovels that may damage the surface.
