Aggregate concrete colours merge the robustness of traditional concrete with the organic beauty of stone. The exposed aggregate technique involves blending selected stone chips into the mix, pouring to form your desired shape, then removing the surface layer to reveal a durable, textured finish.
For Perth homeowners, the benefits are hard to beat: outstanding resilience under our sun, minimal maintenance, inherent slip resistance around pools and driveways, a spectrum of aesthetic options and a more affordable alternative to natural stone.
Installations should meet Western Australian requirements for longevity and quality—refer to the WA Department of Commerce’s Guide to Standards and Tolerances. Colour consistency and UV stability depend on correct iron oxide dosing—see Cement Australia’s FAQs for recommended procedures.
Our top 10 swatches were selected for their proven appeal across driveways, alfrescos and pool surrounds, their adaptability and their lasting performance. As your local experts, Terrastone Architectural Concrete invites you to browse the full exposed aggregate gallery before we count down the most popular finishes for Perth homes.
1. Amber Grey Fine Blend Exposed – A Subdued Mid-Tone for Versatile Spaces
Amber Grey Fine Blend Exposed brings together a soft grey palette and a fine-textured finish, making it one of our most versatile swatches for Perth homes. Its understated elegance adapts seamlessly from sleek modern driveways to relaxed alfresco areas, offering a neutral backdrop that still catches the eye.
Composition and Visual Characteristics
This finish combines uniformly graded aggregates sized between 2–4 mm with a high-quality grey cement matrix. Once the surface layer is gently washed away, you’re left with a consistent mid-grey tone punctuated by delicate stone flecks. Using around 4 % iron oxide pigments by cement weight ensures a UV-stable hue that won’t fade under our harsh sun.
Ideal Applications in Perth Homes
Amber Grey Fine Blend is an excellent choice for:
- Driveways that complement both light-coloured and darker facades
- Garden pathways winding through native plantings
- Pool surrounds, where slip resistance and a calm aesthetic are essential
Whether your home’s style is contemporary or nods to classic design, this mid-tone grey adds cohesion without overpowering other elements.
Design Pairings and Inspiration
To accentuate the gentle character of Amber Grey Fine Blend:
- Add charcoal or black aluminium furniture for modern contrast
- Introduce rich timber decking or screening to warm the palette
- Frame pathways with neutral-toned plantings—think silvery grevilleas or lomandra
These pairings create an inviting outdoor space that feels both grounded and refined.
Maintenance and Sealing Advice
To protect colour vibrancy and guard against wear:
- Reseal every 3–5 years with a clear acrylic sealer
- Clean with mild, pH-neutral detergent and hose down spills promptly
- Inspect annually for surface wear, especially in high-traffic zones
Following these simple steps will help preserve the finish and extend the life of your concrete.

2. Amber White Fine Blend Exposed – Bright Neutral for Open Alfrescos
Amber White Fine Blend Exposed is our go-to swatch when you want an airy, light-reflective surface that makes outdoor living areas feel even more spacious. Its soft white tone remains fresh under Perth’s intense sun, creating a crisp backdrop for alfresco dining and poolside lounging.
Composition and Visual Characteristics
This finish uses a fine mix of pale aggregates—mostly white quartz and light limestone—graded between 1.5–3 mm. Once the top layer is washed off, the result is a near-uniform ivory surface with tiny stone highlights that catch the eye. By incorporating approximately 2 % iron oxide pigment by cement weight, Amber White retains its brightness without yellowing, even after years in full sun.
Ideal Applications in Perth Homes
Amber White Fine Blend works beautifully in areas where you want to maximise light and space:
- Alfresco dining zones that benefit from a bright, clean aesthetic
- Pool decks, where high light reflectance keeps the surface cooler underfoot
- Patios and verandahs, for an open, inviting ambience
This swatch is particularly suited to homes with a coastal or minimalist vibe, but equally complements traditional timber and brick accents.
Design Pairings and Inspiration
To enhance the fresh neutrality of Amber White:
- Pair with crisp white pergolas or shade sails to emphasise geometry and shadow play
- Choose light-toned outdoor fabrics—linen, canvas or soft greys—for furniture cushions
- Introduce potted greenery or vertical gardens to add pops of verdant colour
These elements create a calm, cohesive setting that feels both modern and welcoming.
Maintenance and Sealing Advice
A lighter surface can show spills more readily, so we recommend:
- Resealing every 2–4 years with a low-sheen, breathable sealer to preserve the finish
- Rinsing or hosing down the surface weekly to remove dust and pollen
- Spot-cleaning accidental spills (olive oil, wine, sauces) with a mild, pH-neutral cleaner
Routine care ensures your alfresco area stays crisp and stain-free for years to come.

3. Black Pearl Fine Blend Exposed – Deep, Dramatic Finish for Modern Driveways
Black Pearl Fine Blend Exposed brings a bold statement to any driveway, melding a near-black base with subtle mineral highlights. Its intense coloration and refined texture suit contemporary homes, delivering a striking contrast against lighter facades. Often chosen by homeowners aiming for a sleek, industrial aesthetic, this finish sets your property apart without compromising on practicality.
Composition and Visual Characteristics
This swatch uses premium dark aggregates such as basalt and river pebbles, sized around 2–5 mm, suspended in a rich, black cement matrix. As the surface is revealed, you’ll notice the stone chips gleaming against a charcoal backdrop. To achieve that deep, consistent hue, our mix features approximately 6 % iron oxide pigment by cement weight—enough to saturate the colour while preserving the stone’s natural texture. The result is a sumptuous, velvety finish that remains UV-stable and fade-resistant.
Ideal Applications in Perth Homes
Black Pearl Fine Blend is tailor-made for:
- Driveways where a dramatic entrance makes a lasting impression
- Feature pathways that guide visitors to your front door or garden focal point
- Courtyards and parking areas in modern townhouses or loft-style builds
Its dark tone not only adds visual impact but also masks tyre marks and general wear—ideal for busy households.
Design Pairings and Inspiration
To let this deep shade shine:
- Contrast with light-coloured walls or rendered finishes for a crisp, contemporary vibe
- Introduce stainless-steel or black-framed planters for a cohesive, minimalist landscape
- Soften the look with slender grasses or sculptural succulents in white or metallic pots
These elements enhance the dramatic core of Black Pearl while keeping the overall design balanced and sophisticated.
Maintenance and Sealing Advice
One of the perks of this finish is its dirt-concealing nature. To maintain that lustrous look:
- Apply a high-gloss, solvent-based sealer every 3–4 years to deepen the sheen and protect against staining
- Clean with a gentle detergent and pressure-wash at low pressure to remove built-up grime
- Inspect for minor chips or wear, especially on edges, and repair promptly to avoid moisture ingress
Regular care ensures your driveway retains its striking, showroom-quality finish.
Local Availability

4. Coral Grey Exposed – Warm Grey with Subtle Earthy Undertones
Coral Grey Exposed delivers a cosy, grounded vibe without veering too warm or cool. Its softly mottled surface blends grey tones with gentle rust-coloured flecks, making it perfect for homeowners who want something more inviting than a pure charcoal or dove-grey finish.
Composition and Visual Characteristics
This finish combines a mid-grey cement matrix with a blend of light terracotta and pale sandstone aggregates, typically sized between 3–6 mm. When the top layer is removed, you’ll see softly scattered red-brown stones peeking through a warm grey base. A measured iron oxide dosage of around 3 % by cement weight ensures the earthy tones remain subtle yet noticeable, while UV-stable pigments prevent unwanted fading under Perth’s harsh sun.
Ideal Applications in Perth Homes
Coral Grey Exposed shines in areas where you want a gentle transition between hardscape and greenery. It’s a popular choice for:
- Meandering garden paths that complement native planting schemes
- Pool surrounds, where the warm tones pair well with blue water and sandstone coping
- Alfresco patios aiming for a relaxed, Mediterranean-inspired atmosphere
Whether you’ve got a lush, tropical courtyard or a minimalist urban garden, this swatch brings a touch of warmth without overwhelming the space.
Design Pairings and Inspiration
To make the most of Coral Grey’s earthy charm:
- Frame seating areas with terracotta pots filled with succulents or drought-tolerant natives
- Integrate warm timber decking or slatted screens to echo the aggregate’s rusty hints
- Soften the palette with cream or olive-green outdoor fabrics and cushions
These accents draw out the subtle red flecks and create an inviting outdoor setting that feels cohesive and thoughtfully layered.
Maintenance and Sealing Advice
While the gentle hue hides light dust and debris, it still benefits from routine care:
- Apply a lightly tinted sealer every 3–5 years to deepen the warm undertones without darkening excessively
- Clean with a soft broom or low-pressure hose to remove dirt, then spot-treat spills with a pH-neutral cleaner
- Inspect for wear in high-traffic zones—prompt resealing helps keep the surface looking fresh and uniform
With minimal upkeep, Coral Grey Exposed will continue to lend your outdoor areas that understated warmth year after year.
5. Limestone Natural Exposed – Earthy Beige for Rustic Appeal
Limestone Natural Exposed captures the timeless warmth of creamy, sandy hues, offering a soft yet character-filled finish. Its earthy tone and textured surface bring out the natural charm of stone, making it an ideal choice for homes that lean into rustic or heritage aesthetics.
Composition and Visual Characteristics
This finish is crafted from high-quality limestone chips, typically ranging between 3–8 mm, embedded in a neutral cement matrix. Once the top layer is gently washed away, you’re left with a harmonious blend of beige and ivory fragments. The aggregate’s subtle variations—from pale cream to light tan—create a textured tapestry that feels authentic and inviting. No added pigments are needed here; the beauty comes straight from the natural limestone.
Ideal Applications in Perth Homes
Limestone Natural Exposed suits a variety of outdoor spaces where a soft, rustic look is desired:
- Patios and courtyards, where the warm beige foundation complements terracotta roof tiles and brickwork
- Heritage-style properties or country cottages, tying in with original stone walls and period details
- Garden terraces and low-traffic pathways, enhancing the transition between greenery and hardscape
This swatch lends itself perfectly to areas that benefit from a gentle, unhurried character—think quiet retreats or sun-drenched entertaining nooks.
Design Pairings and Inspiration
To make the most of Limestone Natural Exposed’s rustic appeal:
- Frame seating areas with wrought-iron tables and chairs, their dark metal contrasting beautifully against the light base
- Layer in lush greenery—potted ferns, box hedges or cascading vines—to bring out the stone’s organic warmth
- Incorporate sandstone walls or feature boulders that mirror the aggregate’s natural palette
These elements work in concert to reinforce the earthy, lived-in feel, transforming your outdoor area into a welcoming escape.
Maintenance and Sealing Advice
Keeping this finish looking its best is surprisingly straightforward:
- Reapply a matt-finish sealer every 3–5 years to preserve the natural look without adding unwanted shine
- Sweep regularly with a soft broom and hose down to remove dust, pollen or surface debris
- Address spills promptly with a mild, pH-neutral cleaner to prevent staining
With this minimal upkeep, Limestone Natural Exposed will retain its warm, rustic charm for many seasons to come.
6. Sandstone Exposed – Classic Warm Hue for Timeless Charm
Soft, sunlit and endlessly inviting, Sandstone Exposed delivers a golden-brown palette that feels right at home in Perth’s warm climate. Its timeless appeal draws on the natural beauty of sandstone chips, offering an appearance that’s equally suited to heritage cottages and contemporary builds. Whether you’re welcoming guests at the front gate or hosting a weekend barbecue, this finish lends your outdoor areas an understated elegance.
Composition and Visual Characteristics
Sandstone Exposed is crafted from premium sandstone aggregates—typically sized between 4–8 mm—embedded in a light, neutral cement matrix. Once the surface layer is gently removed, you’re left with a tapestry of warm ochre, buff and honey-coloured stones. The subtle variations in each chip create a lively finish that catches the light, while the natural mineral composition ensures UV stability without the need for added pigments.
Ideal Applications in Perth Homes
This swatch shines in spaces where a welcoming, grounded tone is desired:
- Front entry paths that set a warm, inviting first impression
- Outdoor living zones—patios and verandahs—where a cosy backdrop enhances gatherings
- Communal entertaining areas, such as courtyard seating or alfresco dining nooks
Its solar-reflective properties help keep underfoot temperatures comfortable, making Sandstone Exposed a practical as well as beautiful choice.
Design Pairings and Inspiration
Highlight the golden hues of Sandstone Exposed by introducing cool, contrasting accents:
- Navy or slate-blue outdoor cushions and throws for a crisp colour pop
- Brushed steel or gunmetal furniture frames to balance warmth with contemporary edge
- Earthy terracotta planter pots and native grasses for a seamless link to the landscape
These combinations emphasise both the classic charm and the versatility of the sandstone palette.
Maintenance and Sealing Advice
To prevent efflorescence and preserve the stone’s natural radiance:
- Flush the surface with a mild, pH-neutral detergent every six months to remove built-up salts and dirt.
- Reseal every 3–5 years using a breathable, matt-finish sealer that won’t trap moisture beneath the surface.
- Address spills promptly by hosing off residue—this simple habit keeps the finish looking fresh with minimal effort.
With regular care, Sandstone Exposed will retain its warm glow and textural depth for many seasons to come.
7. Night Sky Exposed – Speckled Dark for Contemporary Edge
Night Sky Exposed brings a dramatic, high-contrast surface to any outdoor area, melding deep charcoal tones with bright mineral flecks. Its speckled finish has become a favourite for homeowners seeking a sleek, modern look that still offers texture and grip. Whether framing a pool deck or punctuating a garden path, Night Sky adds a bold, sophisticated accent to contemporary Perth homes.
Composition and Visual Characteristics
This finish combines dark grey aggregates—often basalt or crushed granite sized between 3–6 mm—with lighter quartz and feldspar inclusions. After the cement matrix is gently washed away, the result is a dynamic constellation of stone chips: the nearly black backdrop causes the pale flecks to pop, creating a striking, almost terrazzo-like effect. A measured iron oxide dosage (around 5 % by cement weight) deepens the charcoal hues and ensures UV-stable performance, so your driveways and decks won’t fade under Western Australia’s harsh sun.
Ideal Applications in Perth Homes
Night Sky Exposed lends itself beautifully to areas where you want both style and function:
- Pool surrounds: the speckled texture reduces slip risk while complementing deep blue water
- Feature garden paths: creates a memorable route through planting beds or courtyards
- Modern home exteriors: pairs seamlessly with monochrome façades and steel detailing
- Alfresco entertaining zones: sets a dramatic stage for outdoor furniture and lighting
Its combination of durability, slip resistance and show-stopping appearance makes it a versatile choice around the house.
Design Pairings and Inspiration
To make Night Sky really shine, consider:
- In-ground LED uplights: flickering beams accentuate the stone flecks after dark
- Monochrome furniture: black frames with white or grey cushions echo the finish’s palette
- Polished concrete elements: use honed or polished grey surfaces nearby to create textural contrast
- Metal planters in matte black or gunmetal: these add sculptural interest without distracting from the aggregate pattern
These design moves will turn your outdoor space into a contemporary retreat, day or night.
Maintenance and Sealing Advice
Although Night Sky’s dark tone hides dirt and tyre marks exceptionally well, regular care keeps it looking its best:
- Apply a non-slip, penetrating sealer every 3–5 years to maintain safety around wet areas and preserve the speckled sheen
- Sweep or hose down monthly to remove leaves, dust and salt spray—especially important in coastal locations
- For stubborn marks, use a gentle, pH-neutral detergent and soft brush, then rinse thoroughly
- Inspect high-traffic zones annually and touch up any small chips to prevent moisture ingress
With minimal but consistent upkeep, Night Sky Exposed will deliver contemporary flair and reliable performance for many seasons to come.
8. Pewter Exposed – Soft Metallic Grey for Subtle Sophistication
Pewter Exposed strikes the perfect balance between understated elegance and contemporary refinement. Its soft metallic grey finish adds a whisper of sheen to outdoor surfaces, creating a sophisticated backdrop without drawing attention away from your garden, furniture or architectural features.
Composition and Visual Characteristics
This swatch features a finely graded mix of silver-toned aggregates—often quartz and light feldspar—ranging from 1.5–4 mm in size. The aggregate blend is suspended in a neutral cement matrix that, once the surface layer is removed, reveals a delicate interplay of shimmer and texture. The natural lustre of the stones gives Pewter Exposed its signature metallic hint, while the uniform aggregate distribution ensures a consistent, smooth finish underfoot.
Ideal Applications in Perth Homes
Pewter Exposed is an excellent choice for areas where you want a touch of sophistication and low-maintenance performance:
- Alfresco floors, lending a subtle shimmer that catches the evening light
- Courtyards and entryways, where the gentle grey tones complement both greenery and hard landscaping
- Low-maintenance garden paths, offering a refined surface that remains cool and slip-resistant
Its soft metallic cast works equally well with modern and transitional home styles, adding depth without overwhelming the palette.
Design Pairings and Inspiration
To accentuate the graceful sheen of Pewter Exposed, consider these design touches:
- Glass balustrades or frameless pool fencing, which let the surface finish shine through without visual clutter
- Light timber furniture—think pale teak or ash—to echo the cool undertones and introduce warmth through texture
- Potted succulents or silver-leafed plants, such as lamb’s ears or artemisia, which harmonise with the aggregate’s subtle sparkle
Together, these elements create a cohesive and effortlessly elegant outdoor setting.
Maintenance and Sealing Advice
To preserve the metallic gleam and protect against wear:
- Apply a solvent-based sealer every 3–4 years; this enhances the natural lustre and provides a durable protective layer
- Clean with a mild, pH-neutral detergent and soft broom or low-pressure hose to remove dirt and prevent any film buildup
- Inspect annually for surface abrasion, particularly in high-traffic zones, and touch up with your chosen sealer as needed
With straightforward upkeep, Pewter Exposed will retain its soft sophistication for seasons to come.
9. Bluestone Exposed – Cool Blue-Grey for Natural Stone Aesthetic
Bluestone Exposed brings the refined look of slate to your outdoor surfaces, blending cool blue-grey tones with a subtly textured finish. This swatch mimics the elegance of quarried bluestone but at a fraction of the cost, creating a natural-stone appearance that feels right at home in Perth’s coastal and contemporary settings.
Composition and Visual Characteristics
- Aggregates: Premium bluestone chips, typically 4–6 mm in size, suspended in a neutral cement matrix.
- Finish: Once the surface layer is washed away, you’ll see a tapestry of slate-like fragments giving a gentle sheen underfoot.
- Colour stability: Natural mineral composition means UV resistance comes built-in—no heavy pigment loads required.
- Texture: Fine to medium exposure offers just enough grip for barefoot comfort without compromising the smooth, cool look.
Ideal Applications in Perth Homes
Bluestone Exposed works beautifully where a crisp, coastal or contemporary aesthetic is desired:
- Pool surrounds, where the cool grey contrasts with aqua water and helps keep the surface comfortable underfoot (see our guide on pool surrounds).
- Shaded patios and alfresco areas, providing a neutral canvas that complements both bold and muted décor.
- Pathways and garden steps, guiding visitors through lush greenery with a polished yet natural feel.
Design Pairings and Inspiration
To accentuate the bluestone’s cool palette:
- Frame pool decks with crisp white trim or glass balustrades for a resort-style look.
- Combine with aqua-toned outdoor cushions or plump navy throws to echo the stone’s blue undertones.
- Introduce potted palms, cycads or coastal grasses to soften edges and add organic contrast.
These elements turn your outdoor area into a refined retreat that celebrates both texture and tone.
Maintenance and Sealing Advice
Bluestone Exposed is practical as well as attractive. Keep it looking its best by:
- Applying a penetrating, breathable sealer every 3–5 years to guard against moisture ingress without trapping vapour.
- Cleaning quarterly with a soft broom and low-pressure water—avoid high-strength acids or alkalis that can etch the stone.
- Rinsing spills promptly and using a pH-neutral detergent for stubborn spots, then rinsing thoroughly.
Regular care ensures the cool blue-grey finish remains striking, season after season.
10. Whitehaven Exposed – Bright, Coastal White for Beachside Vibes
Whitehaven Exposed captures the essence of sunlit shores right underfoot. Its crisp, luminous finish reflects Perth’s brilliant daylight, creating a fresh, spacious feel that’s perfect for homes near the coast or anyone craving a breezy, resort-style ambience.
Composition and Visual Characteristics
Whitehaven Exposed is crafted with premium white quartz aggregates, sized between 1.5–3 mm, embedded in a pale cement matrix. As the surface layer is removed, the tiny quartz fragments sparkle in the sun, delivering a near-uniform white expanse with subtle flecks of glinting crystal. Thanks to the natural purity of the quartz, there’s no need for heavy pigments—UV stability and colour integrity come straight from the stone.
Ideal Applications in Perth Homes
- Coastal properties, where the bright white surface accentuates sea-breezes and ocean views
- Pool surrounds, where high light reflectance keeps surfaces cooler underfoot
- Sun-drenched patios and alfresco lounges, amplifying daylight and creating an open, airy atmosphere
Whether you’re designing a beachfront retreat or a garden courtyard, Whitehaven sets a pristine stage for outdoor living.
Design Pairings and Inspiration
- Navy or rich teal cushions and shade sails, echoing the hues of nearby water
- Driftwood or bleached timber furniture to reinforce a relaxed, beach-chic vibe
- Lush palms, cycads or cordylines in terracotta or white pots, introducing sculptural greenery against the luminous backdrop
These elements celebrate the coastal narrative and keep the palette fresh and inviting.
Maintenance and Sealing Advice
To preserve Whitehaven’s dazzling brilliance:
- Sweep or gently hose down weekly to clear salt spray, pollen and light debris
- Spot-clean spills immediately with a mild, pH-neutral detergent
- Reseal every 2–4 years using a breathable, clear sealer formulated for light-coloured aggregates
