Exposed Aggregate Sealing Perth

Make your exposed aggregate concrete shine and last longer with our exposed aggregate sealing services in Perth. Exposed aggregate surfaces – like driveways, walkways, and pool decks – are prized for their decorative appearance, where pebbles and stones are visible on the surface. However, without proper sealing, exposed aggregate can lose its luster, accumulate stains, and even start to degrade as the cement matrix weathers away. Perth Blast n Seal offers specialized sealing for exposed aggregate that will enrich the color of the stones, protect the surface from damage, and make maintenance a breeze. Our professional team ensures your aggregate is sealed evenly and effectively for a beautiful, durable finish.

Why Seal Exposed Aggregate?

Even though exposed aggregate concrete is robust, it greatly benefits from sealing. Here’s why sealing is highly recommended for your exposed aggregate surfaces:

Enhance Color and Appearance: Sealing brings out the rich variety of colors in the aggregate, giving the surface a vibrant “wet look” that many homeowners love. The pebbles will appear more striking, and the overall surface gains a subtle sheen (depending on the sealer used). This instantly improves curb appeal, making an older driveway or patio look refreshed.
Protect Against Stains: Like any concrete, exposed aggregate is porous. Unsealed, it can soak up oil leaks, BBQ grease, drink spills, or leaf tannins, leading to unsightly stains that are tough to remove. A sealer fills those pores and creates a protective layer, preventing most substances from penetrating. Spills remain on the surface so they can be cleaned off before causing permanent marks.
Prevent Surface Degradation: Over time, weather exposure can erode the cement paste that holds the aggregate stones in place. This can lead to loose pebbles or a rough, dull texture. Sealing shields the surface from rain, wind, and UV damage. It effectively “locks in” the stones and the concrete, reducing wear from foot traffic and the elements. A sealed exposed aggregate surface is less likely to develop issues like pitting or loss of aggregate.

Easier Cleaning and Maintenance: A sealed aggregate surface won’t trap dirt and algae as easily. The smooth, sealed finish means grime sits on top rather than ingraining itself. This makes routine cleaning (like hosing down or sweeping) more effective. Additionally, when it’s time for a deep clean, a sealed surface will always clean up better than an unsealed one. In short, sealing keeps your outdoor area looking cleaner in between professional cleanings.
Extend Lifespan: By mitigating damage from stains and weather, sealing helps your exposed aggregate last longer in good condition. It’s a cost-effective way to protect your investment in a driveway or patio. You’ll likely get more years of use before any major restoration or resurfacing is needed.

Our Exposed Aggregate Sealing Process

Perth Blast n Seal’s process for sealing exposed aggregate is designed for quality and durability:

Preparation (Cleaning & Drying): We will first ensure the aggregate surface is completely clean. Usually, this involves a high-pressure wash to remove all dirt, mildew, and any existing sealant remnants. (We can coordinate a combined cleaning and sealing service for you — after a thorough clean, we proceed to sealing once the surface is dry.) It’s vital that the concrete is fully dry before sealing, as moisture can hinder the sealer’s effectiveness. We typically plan for a day of drying after cleaning if needed, choosing a period of clear weather for the project.
Choosing the Right Sealer: There are a couple of sealer options for exposed aggregate, and we’ll select the one that meets your goals. The common choice is a solvent-based acrylic sealer which imparts that glossy wet look and forms a protective film. Alternatively, we have penetrating sealers for those who prefer a more natural, low-sheen finish. In both cases, our products are UV-stable and formulated for Western Australian conditions, ensuring they won’t yellow or degrade quickly under the Perth sun.
Application: Our team applies the sealer uniformly across the surface using professional sprayers or rollers. We usually apply two coats of acrylic sealer on exposed aggregate for even coverage and optimal protection. The first coat penetrates and seals the pores; the second coat builds a durable finish on top. We carefully work the sealer into the surface and ensure no area is missed – including edges and corners. If using a penetrating sealer, multiple coats may be applied wet-on-wet to fully saturate the porous concrete.
Finishing & Curing: After application, we allow the sealer to cure undisturbed. Acrylic sealers will typically be touch-dry in a few hours, but need 24-48 hours to harden fully. We advise keeping cars and foot traffic off the sealed surface during this curing period. Once cured, you’ll notice a uniform sheen and richer color on your aggregate. We do a final quality check to make sure the finish is even and meets our high standards. We’ll also give you maintenance tips, like when to avoid parking heavy vehicles and how to spot-check for water beading, which indicates the seal is working.

Our meticulous approach to exposed aggregate sealing in Perth ensures that you get a long-lasting seal that won’t peel or flake. The end result is an attractive, well-protected surface you can enjoy for years.

Where You’ll Find Exposed Aggregate (We Seal Them All)

Exposed aggregate is used in various parts of residential and commercial properties. We have experience sealing all of the following:

Driveways and Front Paths: One of the most common uses – sealing these surfaces protects against vehicle stains and adds curb appeal to your home’s entrance.
Patios and Alfresco Areas: Outdoor entertaining areas often use exposed aggregate for its decorative look. Sealing prevents food and drink stains during gatherings and makes post-party cleanup easier.
Pool Decks: Around swimming pools, sealing is very important. It helps protect the concrete from pool chemicals and salt (if it’s a saltwater pool), and inhibits the growth of mold that can make pool areas slippery. We can use sealers that enhance appearance while keeping slip-resistance a priority.
Commercial Entrances and Courtyards: Many businesses and public spaces in Perth have decorative aggregate finishes. We offer commercial scheduling to seal these with minimal disruption, improving their appearance and reducing maintenance needs.

No matter where your exposed aggregate is located, our team can provide a solution to keep it looking great and performing well.

Why Choose Perth Blast n Seal for Exposed Aggregate Sealing?

Specialized Knowledge: Sealing exposed aggregate is a bit of an art – it requires understanding how much sealer the surface will absorb and how to apply it evenly without pooling or patchiness. Our technicians have honed this skill through years of experience. We know the pitfalls (like avoiding applying sealer on overly hot days which can cause blisters, or ensuring moisture isn’t trapped) and we take care to do it right the first time.
Quality Sealing Products: We use top-tier sealers from trusted manufacturers. The products we apply are commercial grade, not the diluted versions from big-box stores. This means superior bonding, longer lifespan, and better overall performance. The sealers are also non-yellowing and won’t turn white in wet conditions – a common issue with cheap sealants.
Attention to Detail: Preparation is key for us. We won’t seal over a dirty or damp surface. Our team gives full attention to cleaning and drying, as well as weather conditions, to ensure optimal results. During application, we protect nearby surfaces (like walls, garage doors, plants) from any overspray. The final appearance is important to us, so we take the time to achieve a consistent finish.
Customer Satisfaction and Support: From start to finish, we make the process easy for you. We offer prompt quotes, fair pricing, and flexible scheduling. Our crew is polite, punctual, and professional on site. If you have questions about the process or caring for your sealed aggregate later, we’re always happy to provide guidance.

Exposed Aggregate Sealing Perth – FAQs

Q: How often should exposed aggregate be resealed?
A: In our Perth climate, we generally recommend re-sealing exposed aggregate every 2-3 years. High-traffic driveways or surfaces that get a lot of sun may benefit from more frequent re-sealing (around every 2 years) as the UV exposure can wear down sealers over time. Lower traffic areas or shaded patios might stretch closer to 3-4 years between coats. We can give you a specific recommendation based on the sealer used and the conditions at your property. Regular maintenance coats will ensure continuous protection and keep the surface looking its best.

Q: Will sealing exposed aggregate make it slippery, especially when wet?
A: Exposed aggregate typically has a textured finish that provides good slip resistance. When we apply an acrylic “wet look” sealer, it can initially feel slightly smoother underfoot due to the thin film on the surface. However, because the aggregate stones still protrude, it usually remains quite slip-resistant. For pool areas or if you have concerns, we can add a non-slip additive to the sealer for additional grip without significantly changing the appearance. Alternatively, using a penetrating sealer will maintain the original texture completely. We will discuss the best option with you to ensure safety.

Q: My exposed aggregate driveway is old and looks dull – will sealing help if it’s never been sealed before?
A: Absolutely. In fact, first-time sealing of an older exposed aggregate surface can yield dramatic improvements. We’ll start with a thorough cleaning to remove built-up grime and any superficial cement layer. Once cleaned, applying a sealer will bring out the colors of the stones and give the surface a refreshed look, often making it look similar to when it was new. The sealer will also start protecting the now-exposed pores. Even if your driveway has never been sealed, it’s never too late to do it – it will both beautify and fortify the concrete.

Q: Can I seal my exposed aggregate myself?
A: While it’s possible as a DIY project, it can be tricky to get right. Achieving an even application without over-applying is important (too much sealer can cause a white haze or bubbles). Surface prep is also critical – any dirt or moisture left in the concrete can lead to poor results. Professional equipment helps in applying a uniform coat. We often get calls to fix or re-do DIY sealing jobs. Given the value of your driveway or patio, it’s worth using experienced professionals for the best outcome. We handle everything, including sourcing the best sealer for your needs and ensuring the weather conditions are suitable on the day of application.
