Colour Through Concrete: Full-Depth Colouring & Where To Buy

Across Perth’s suburbs, driveways, patios and pool surrounds are breaking free from the familiar grey palette. Colour through concrete, also known as integral or full-depth colouring, embeds pigment into every layer of the slab rather than coating the surface, creating a uniform tone that won’t peel or fade.

By blending high-performance pigments into the mix, this approach delivers long-lasting colour—from muted neutrals to striking accents—while standing up to foot traffic, weather and spillages with minimal maintenance, making it ideally suited to Western Australia’s sun-soaked conditions.

In the sections that follow, you’ll discover how integral colouring works, explore design ideas for outdoor living and pool edges, understand the technical standards that ensure a flawless finish, and learn where to source trusted suppliers and specialist installers across Perth and beyond.

Understanding Full-Depth Colouring in Concrete

Full-depth colouring—often called integral colouring—means blending pigment right into the concrete mix rather than applying it on the surface. This ensures every section of the slab, edge to edge, shares the same hue. Unlike surface treatments that sit atop the concrete and can wear away or fade over time, integral pigments become part of the cement matrix. The result is an even, enduring colour that resists traffic abrasion, weathering and chemical spills.

Integral pigments bind with the cement paste during hydration, locking in colour molecules throughout the slab. This process delivers consistent tones—from soft greys and earthy beiges to bolder reds, blues and greens—without worrying about peeling or flaking. Whether you’re specifying a driveway, patio or pool surround, full-depth colouring opens up a palette that stays true for years. For a closer look at how coloured concrete can elevate your home, explore Terrastone’s coloured concrete overview.

What Is Full-Depth (Integral) Colouring?

Integral colouring starts at the batching plant. As the wet mix is prepared, measured pigments—usually iron oxide powders—are added directly to the drum. These pigments disperse evenly among cement and aggregates, infiltrating every layer of the pour. Chemically, the pigments remain stable in the highly alkaline environment of curing concrete, ensuring the colour we see today endures tomorrow. You’ll often spot integral colour on driveways, patios and pool decks where a uniform, low-maintenance finish is paramount.

Integral vs Surface Colouring Methods

There are several ways to introduce colour to concrete, each with its own strengths:

• Integral Colouring
– Pigment mixed through full depth
– Pros: fade-resistant, uniform, low upkeep
– Cons: requires accurate batching, sample sign-off

• Shake-On Colour Hardeners
– Dry pigment applied to wet slab surface
– Pros: intense surface colour, texture added
– Cons: limited to top layer, may wear in high traffic

• Water-Based Dyes and Stains
– Applied post-cure to create variegated effects
– Pros: high design flexibility, stencil patterns
– Cons: subject to fading, periodic re-application needed

Why Integral Colouring Is Preferred

Integral colouring stands out for its resilience and consistency. Colours won’t chip or peel because the pigment is not just on the surface—it’s through the slab. Repairs blend seamlessly, as any new concrete with the same mix proportions will match the original colour. As one industry expert puts it, “Coloured concrete is just as strong and durable as any other decorative concrete.” Whether your priority is longevity, minimal maintenance or a uniform look, full-depth colouring delivers on all fronts.

Methods of Colour Integration in Concrete

When it comes to adding colour to concrete, there’s more than one way to achieve a standout finish. The most common approaches include integral colouring, shake-on hardeners, water-based dyes and stains, and an array of decorative finishes. Each method has its own advantages, suited to different project scales, budgets and design ambitions. Below, we’ll unpack how each technique works and where it shines.

Integral Colouring (Full-Depth)

Integral colouring involves blending pigment right into the wet concrete mix at the batching plant. Typically, iron oxide powders dominate the pigment palette, thanks to their lightfastness and chemical stability in alkaline environments. Once poured, every layer of the slab carries the same consistent hue, making it ideal for large driveways, patios and exposed edges where uniform colour and low maintenance are prized.

Shake-On Colour Hardeners

Shake-on hardeners (also known as colour hardeners) are dry pigment blends broadcast over a freshly screeded concrete surface. As they hydrate into the top 2–3 mm, they form a coloured wearing course with improved abrasion resistance. This surface-level technique offers intense, uniform colour on overlays, light-duty slabs or decorative banding—but it won’t carry the hue through the full slab depth.

Water-Based Dyes and Stains

Applied after the concrete has cured, water-based dyes and stains penetrate the surface to create translucent, variegated tones. They’re perfect for injecting artistic flair—think stencilled patterns or subtle marbling—on polished, honed or broom-finished floors. While they open up a vast design playground, expect to reapply periodically in high-sun or high-traffic areas, as UV exposure and wear can gradually soften the effect.

Other Decorative Concrete Finishes

Beyond integral colour, a host of decorative finishes can elevate the look and feel of your concrete. Exposed aggregate reveals natural pebbles for a textured, slip-resistant surface; honed and polished finishes bring a refined sheen; liquid limestone offers a smooth, stone-like appearance. Often, these finishes are paired with integral pigments to marry colour and texture—explore more of Terrastone’s decorative finishes to see how different techniques combine.

Integral Colouring Process Explained

Getting a consistent, full-depth colour in concrete hinges on meticulous preparation, precise mixing and careful finishing. From choosing the right pigment to handling the freshly poured slab, each step ensures the final outcome stays true to your vision and stands up to Perth’s harsh sun and heavy use. Below, we break down the key stages of the integral colouring workflow.

Pigment Selection and Properties

Choosing the right pigment is the first crucial decision. Iron oxide powders—available in natural and synthetic forms—dominate the industry thanks to their exceptional colourfastness and resistance to alkaline environments. Natural oxides offer a slightly variegated look, while synthetic pigments deliver more uniform tones. Key factors to consider include:

• UV resistance: prevents fading in direct sunlight
• Particle size: finer particles disperse more evenly but may require careful dosing
• Colour range: from earthy reds and yellows to blacks and greys

By selecting pigments that comply with Australian standards for concrete colouring, you’re setting the stage for a long-lasting, fade-resistant finish.

Batching and Mixing Techniques

Once you’ve settled on a pigment, the next step is to integrate it into the mix. At the batching plant or on-site mixing station, follow this general sequence:

1. Add water to the drum to wet the internal surfaces
2. Introduce cement and coarse aggregates
3. Blend in fine aggregates for a consistent texture
4. Finally, add the pre-measured pigment

Maintaining the correct order helps prevent pigment clumping and ensures uniform distribution. Trial batches and slump tests are essential to verify consistency—measure slump before and after pigmentation to confirm workability hasn’t been compromised.

Ensuring Colour Consistency

Uniform colour from pour to pour relies on thorough record-keeping and visual checks. Before full-scale pouring, conduct on-site sample pours using the exact mix design and pigment dosage. Once the test panel cures, inspect it under natural light to verify hue and surface quality. Keep detailed logs of pigment batch numbers, weights and mixing times; these records serve as a reference if additional concrete is required later in the project.

Pouring and Finishing Practices

When it’s time to pour, handling the mix gently is paramount to avoid segregation, which can lead to colour blotches. Use controlled vibration to settle the concrete without overworking it. To finish:

• Screed the surface for level flats
• Bullfloat to bring the cream (finest paste layer) to the surface
• Employ a power trowel or hand trowel depending on the desired texture

Timing is critical—too early and you’ll drag excess paste, too late and the surface becomes hard to finish. Aim for the optimal window when bleed water has evaporated but before the mix stiffens. This approach yields a smooth, uniform appearance that showcases the full-depth pigmentation.

Pigments and Additives Used in Integral Colouring

Adding colour to every layer of a concrete slab relies on more than just pigment — it calls for a balance of chemistry and craftsmanship. Selecting the right pigments and performance-enhancing additives ensures your coloured concrete stands up to the elements, maintains vivid tones and delivers the durability Perth homeowners demand. In this section, we’ll explore the star performer in the industry — iron oxides — compare natural versus synthetic options, outline dosage rates for various shades, and highlight key admixtures that lock in colour and fend off UV damage.

Iron Oxides: The Industry Standard

Iron oxide pigments lead the pack thanks to their remarkable resistance to UV light and alkalinity. They’re available in red, yellow and black oxides, each offering a distinct hue:

• Lightfastness: Iron oxides resist fading under intense sun exposure.
• Chemical stability: They don’t break down in the highly alkaline environment of curing concrete.
• Colour depth: By blending primary oxide colours, you can create a spectrum from earthy terracottas to deep charcoals.

As a rule of thumb, iron oxide powders should comply with Australian Standards for concrete colouring, ensuring consistency from one batch to the next.

Natural vs Synthetic Pigments

When sourcing pigments, you’ll encounter two main categories:

• Natural Pigments
  • Sourced from minerals and earth ores.
  • Offer a subtle variegation, adding character and a slightly mottled appearance.
  • Tend to be more cost-effective but can vary slightly between batches.
• Synthetic Pigments
  • Manufactured for precise, uniform colour.
  • Deliver exact replication of a chosen shade, ideal for projects where consistency is paramount.
  • Usually come at a premium but simplify quality control.

Deciding between the two often comes down to whether you prefer the nuanced warmth of natural oxides or the predictable uniformity of synthetics.

Dosage Rates and Colour Intensity

The intensity of your concrete’s colour depends largely on the amount of pigment added. Below is a general guideline based on pigment percentage by weight of cement:

Most projects settle in the 2–5% range to balance colour vibrancy with cost-effectiveness. Always conduct a sample pour to confirm the exact shade under site conditions.

Admixtures for Durability and UV Stability

Beyond pigments, admixtures play a vital role in preserving both the colour and structural integrity of the slab:

• UV Inhibitors
  • Added to the mix to absorb or reflect harmful UV rays.
  • Minimise long-term fading, especially on north-facing surfaces.
• Water-Repellent Additives
  • Reduce moisture absorption, cutting down on efflorescence (salt deposits) that can dull colours.
  • Improve freeze–thaw resistance in cooler climates.
• Plasticisers and Superplasticisers
  • Enhance workability without extra water, promoting even pigment dispersion.
  • Allow for lower water–cement ratios, boosting overall strength and reducing surface cracking.

By combining the right pigments with performance additives, you get a concrete finish that not only looks great on installation day but keeps its colour and integrity for years to come.

Advantages of Colour Through Concrete

Choosing colour through concrete delivers more than just eye-catching aesthetics. Because pigment is blended into every layer of the slab, the benefits reach right to its core—ensuring your outdoor surfaces remain vibrant, durable and low-maintenance for years. From resisting abrasive traffic on driveways to offering a wealth of design possibilities, integral colouring stands apart from surface-only treatments.

Beyond a uniform hue, full-depth colouring transforms concrete into a long-lasting backdrop for your home’s exterior. Here’s how it outperforms other methods:

Exceptional Durability and Wear Resistance

Integral pigments become part of the cement matrix, so the colour won’t chip, flake or peel away under heavy use. Driveways, pathways and patio floors see constant foot and vehicle traffic, not to mention the harsh glare of a Perth summer. Full-depth colouring:

• Retains even tone despite abrasion from tyres and garden furniture
• Withstands chemical spills—think pool chlorine or barbecue oils—without blotching
• Continues to look fresh where surface coatings would quickly wear thin

Whether you’re pulling in every day or entertaining outdoors, the slab holds up beautifully under pressure.

Low Maintenance and Easy Cleaning

One of the biggest perks of integral colour is how little effort it requires to stay looking great. There’s no need for annual repainting or intensive recoats. To keep your coloured concrete in top shape:

• Sweep or hose down regularly to remove dust and debris
• Use a mild detergent or pH-neutral cleanser for stubborn stains
• Employ a light pressure wash (under 1300 psi) once or twice a year

A simple seal every few years enhances stain resistance and keeps your chosen hue locked in, without disrupting the original finish.

Design Flexibility and Aesthetic Versatility

Full-depth colouring unlocks a palette as broad as your imagination. Since pigments are mixed through the slab rather than applied on top, you can:

• Incorporate contrasting borders or geometric inlays in the same pour
• Blend multiple pigments for subtle gradations or bold two-tone effects
• Coordinate seamlessly with decorative finishes—exposed aggregate, honed or polished—without worrying about colour mismatch

From classic neutrals to statement reds and blues, integral colouring supports creative layouts, custom logos or feature bands that elevate your outdoor living area.

Colour Longevity vs Surface Treatments

Over time, surface treatments like stains and paints need regular touch-ups. Full-depth colouring, however, relies on the inherent stability of pigments within the concrete. Consider this comparison:

By choosing colour through concrete, you lock in a durable pigment that weathers naturally, sidestepping the cycle of peel, recoat and repair. For homeowners seeking a long-term solution that balances performance and flair, integral colouring remains unmatched.

Design Applications: Driveways, Alfresco, Pool Surrounds and More

Concrete that’s coloured through its entire depth isn’t just a technical feat—it’s a design tool. Whether you’re after a statement driveway that lifts your property’s kerb appeal, a seamless alfresco zone for relaxed entertaining or a pool surround that marries safety with style, integral colouring delivers. Below, we look at common applications and how to tailor each to Perth’s unique climate and aesthetic.

Driveways: Blending Functionality and Curb Appeal

Your driveway is often the first thing guests see, so why stick with standard grey? Full-depth colour allows you to introduce:

• Contrasting borders or inlays in muted greys, warm beiges or terracotta tones
• Subtle stamped patterns—such as cobblestone or ashlar slate—for texture and interest
• Two-tone blends that complement roof tiles, brickwork or landscaping

By embedding pigment throughout, the surface remains fade-resistant under relentless WA sun and won’t scuff under heavy vehicle traffic. For inspiration and case studies on coloured concrete driveways in Perth, explore Terrastone’s gallery of driveway projects.

Alfresco and Outdoor Living Areas

Alfresco spaces should flow effortlessly from indoors to out. Integral colour helps achieve that continuity by matching patio slabs to internal flooring or coordinating with timber decking. Consider:

• Light neutrals that reflect heat, keeping the surface cool under bare feet
• Earthy hues that blend with garden borders and planter beds
• Seamless transitions with no unsightly joins or changes in height

With low maintenance demands, a coloured concrete alfresco area stays inviting year after year—ideal for summer barbecues or winter gatherings around a fire pit.

Pool Surrounds: Safe and Stylish Surfaces

Pool decks need to tick two boxes: safety and style. Full-depth pigmentation combined with a suitable texture provides slip resistance without the look of a rough finish. Tips for a winning pool surround:

• Opt for pale tones—like oyster, sand or light grey—to minimise heat absorption and glare
• Pair with honed or broomed textures to create a secure, non-slip underfoot
• Coordinate the surrounding colour with pool tiles or coping stones for a cohesive scheme

Integral colour resists chlorine splashes and UV exposure, so your poolside surface remains crisp and uniform long after installation.

Commercial and Interior Floors

Integral colour isn’t confined to the outdoors. Polished coloured concrete has become a staple in cafés, galleries and retail outlets across Perth, offering:

• A hygienic, seamless floor that’s easy to clean and maintain
• Low-VOC surfaces that contribute to healthier indoor air quality
• Custom colours that reinforce branding or interior décor palettes

Whether you’re planning a boutique studio or channeling an industrial-chic look in a warehouse conversion, full-depth colouring provides a resilient base that looks as good on Day 1 as it does a decade later.

Selecting the Right Colour and Finish

Choosing the right colour and finish for your concrete is more than an aesthetic decision—it impacts performance, comfort and how well your new surface integrates with its surroundings. Because concrete pigments can appear differently under various lighting and in combination with other materials, testing samples under actual site conditions is essential. Involve your builder or contractor early to speed up approvals and avoid costly changes later.

Swatches, Samples and Visualisation

Physical swatches are the easiest way to see how a pigment behaves in your own space. Terrastone offers a selection of concrete swatches you can take home to view at different times of day and next to existing finishes. Once you’ve narrowed your options, request a small on-site sample pour—a live mock-up that reveals the true tone and texture under local conditions. To accelerate decision-making, many clients also use digital visualisers to overlay potential colours onto photos of their patio or driveway before making a final call.

Impact of Colour on Solar Heat Absorption

The shade you choose directly influences how much solar heat your concrete absorbs. Darker colours draw in more heat, which can make pool surrounds or alfresco areas uncomfortably hot underfoot, especially in Perth’s glare. Lighter tones reflect sunlight, keeping surfaces cooler and reducing thermal stress cracks. For a detailed discussion on how colour interacts with thermal mass and solar radiation, see the “Thermal Mass and Heat Reflection” section below.

Coordinating Concrete with Surrounding Materials

Your concrete shouldn’t compete with, but complement, the rest of your exterior palette. Consider how your chosen hue will sit alongside timber decking, pavers, brickwork and lush plantings. Soft greys can echo steel frames and aluminium windows, while warm beiges and terracottas feel right at home with brick veneer and sandstone features. By reviewing swatches against existing materials on-site, you’ll ensure a seamless transition between new concrete areas and the rest of your home.

Custom Colour Matching and Blends

When a standard palette isn’t quite right, bespoke blends come to the rescue. Terrastone can match virtually any shade—whether you’re working from RAL codes, paint swatches or photos of your inspiration samples. By combining two or more pigments in precise ratios, you can create a truly unique tone or even subtle colour gradations across large areas. This custom approach is ideal for feature bands, pool edges or any detail that demands a one-off finish.

Quality Control and Industry Standards

Ensuring your colour through concrete meets both aesthetic and structural benchmarks starts with rigorous quality control and strict adherence to Australian standards. From the moment the mix is designed to the final handover, each stage requires clear criteria, testing protocols and thorough documentation. By following these guidelines, you reduce the risk of colour variation, compromised strength or costly rework.

Australian Standard AS 1379:2017 – Mix and Tolerance Criteria

Australian Standard AS 1379:2017 governs the specification and supply of concrete, laying out requirements for mix design, production and acceptance. Key points include:

• Mix Design Parameters: Defines limits for cement content, aggregate grading and water–cement ratio to achieve targeted strength and workability.
• Tolerance Levels: Sets acceptable variances in component weights and moisture levels, critical for consistent pigment distribution and uniform colour.
• Acceptance Standards: Details criteria for compressive strength, slump, air content and temperature control at delivery.

By specifying AS 1379 compliance, you ensure each load of coloured concrete arrives with documented mix proportions. Clear pigment dosing in accordance with the mix design keeps shades consistent from batch to batch.

Testing for Colour Uniformity and Strength

Quality control relies on a blend of laboratory and on-site tests:

• Laboratory Colourimeter Analysis: Measures reflected light to quantify colour deviation, verifying that pigment doses meet the selected shade.
• Compressive Strength Tests: Samples cast from test panels are crushed at specified ages (7, 28 days) to confirm structural performance aligns with design specifications.
• On-Site Test Panels: Poured and cured under actual site conditions, these panels provide a visual reference for hue, texture and finish before full-scale pours commence.

Regular testing at critical stages catches issues—such as pigment clumping or unintended shade shifts—before they affect the main installation.

Documentation and Certification

Transparent documentation is vital for handovers and future maintenance:

• Test Reports: Include mix design records, pigment batch numbers, slump, air content and strength results.
• Compliance Certificates: Suppliers should provide certificates confirming AS 1379:2017 adherence, and any additional product specifications (e.g., pigment UV resistance).
• Delivery Dockets: Detail load weights, arrival times and temperature logs to verify compliance with project requirements.

This documentation trail not only protects you if disputes arise, but also guides any later repairs or extensions by matching exact mix and pigment details.

Vetting and Selecting a Supplier

Choosing the right supplier or contractor can make or break the success of your coloured concrete installation. Use this checklist to vet potential partners:

• Standards Compliance: Confirm they operate to AS 1379:2017 and relevant decorative concrete guidelines.
• Sample Approval Process: Ask for mock-up panels and swatch sign-off procedures to lock in your selected hue.
• Portfolio Review: Examine completed projects—ideally in similar climates—to assess quality, colour consistency and finish.
• Client References: Speak with previous customers about on-time delivery, communication and problem resolution.
• Project Management: Ensure there’s a single point of contact (for example, Terrastone’s dedicated project manager) to coordinate testing, approvals and handover.

By selecting a supplier with proven quality systems and a transparent approval workflow, you’ll secure a colour through concrete installation that lives up to both your design vision and performance expectations.

Thermal Mass and Heat Reflection: Colour Impact on Performance

Concrete’s thermal properties go beyond structural support—they influence how your outdoor areas absorb, store and release heat. Understanding thermal mass and the role of surface colour can make a significant difference to comfort underfoot and energy efficiency in Perth’s hot climate. In this section, we’ll unpack the science and offer practical tips on choosing and caring for coloured concrete surfaces.

What Is Thermal Mass?

Thermal mass refers to a material’s ability to absorb heat during the day and release it slowly when temperatures drop. High-mass materials like concrete act as a heat sink, moderating temperature swings in and around your home. By storing excess solar energy, a concrete slab can:

• Keep indoor spaces cooler in the afternoon by drawing heat away.
• Release warmth at night, reducing temperature extremes.
• Balance fluctuations in external temperatures, enhancing year-round comfort.

For a deeper dive into the fundamentals of thermal mass, see this guide from Your Home.

How Colour Affects Solar Heat Absorption

Surface colour has a direct impact on how much solar radiation concrete absorbs:

• Light-coloured finishes reflect more visible and infrared light, typically staying 10–20°C cooler than darker alternatives.
• Dark pigments draw in heat, warming up quickly under direct sun and holding that heat longer into the evening.

Imagine two pool decks side by side: a pale oyster-toned slab might register around 45°C on a midday summer day, whereas a charcoal surface could spike above 65°C. When selecting a hue, consider how hot the surface needs to stay—or how cool you’d like it to be for bare feet, pets and poolside lounging.

Best Colours for Australian Climates

In Perth’s sun-drenched conditions, lighter, more reflective tones are often the smart choice, especially for north-facing areas that see all-day exposure. Recommendations include:

• Soft greys and beiges, which offer a neutral backdrop and moderate heat gain.
• Sandstone, oyster or off-white blends that reflect the majority of solar energy.
• Muted terracotta or warm neutrals where a touch of colour is desired, without the intense heat load of deeper reds or blacks.

By pairing your colour choice with the orientation of the slab, you can strike a balance between design intent and thermal comfort.

Strategies to Manage Heat in Outdoor Spaces

Even with a reflective finish, Perth summers can be relentless. These strategies help keep your coloured concrete areas cooler and more enjoyable:

• Install shade structures—pergolas, retractable awnings or shade sails—to block direct sun during peak hours.
• Apply a reflective or light-tinted sealer to boost albedo (reflectance) and add a layer of UV protection.
• Incorporate landscaping elements such as deciduous trees or climbing vines to provide seasonal shade.
• Use textured finishes—like broom or exposed aggregate—that scatter light and reduce surface temperature slightly compared to smooth trowelled slabs.

By combining smart colour choices with passive cooling tactics, you’ll enhance both the aesthetic and functional performance of your coloured concrete installations.

How to Buy Colour Through Concrete: Suppliers and Purchasing Options

Buying integral colour concrete involves choosing between ready-mix suppliers, pigment-only providers or full-service installers. Each comes with its own ordering requirements, minimum quantities and lead times. Whether you’re a homeowner specifying a new driveway or a builder managing multiple sites, understanding the supplier landscape helps you streamline procurement, control costs and lock in your chosen hue.

Ready-Mix Suppliers of Integral Colour Concrete

Major concrete producers in Western Australia offer integral colour as an add-on to standard ready-mix orders. Leading brands include:

• Boral: Their Colori® range features over 25 oxide colours, typically with a 2–3 m³ minimum and a 48-hour lead time.
• Dulux Avista: Colour Through Oxide comes in water-soluble bags for batching; orders generally start from 5 m³ with a 3–5 business-day turnaround.
• CCS (Concrete Colour Systems): Supplies full-depth coloured mixes from 1 m³, often scheduled within 24 hours.

When ordering, specify your colour code and pigment dosage (percentage of cement weight). Suppliers will provide technical datasheets and usually recommend an on-site sample pour to confirm the shade under real conditions. Peak building season can affect delivery slots, so book early to secure your desired date.

Pigment and Oxide Suppliers

If you have on-site batching or a mobile mixer, sourcing pigments separately can be cost-effective for smaller volumes or specialist mixes. Key suppliers include:

• Concrete Colour Solutions: Iron oxide powders in natural and synthetic grades, available in 25 kg bags or 1 T bulk; lead times are typically 7–10 days for custom shades.
• Premix: Under the Stylecrete Colour-Thru banner, offers pre-measured pigment sachets from 10 kg packs, with many stock colours ready to ship.

Ordering in bulk reduces price per kilogram but requires secure, dry storage. Always ensure pigments comply with AS 1379 and request batch certificates to maintain colour consistency across deliveries.

Decorative Concrete Contractors and Specialists

For a turnkey approach, decorative concrete specialists handle everything—from colour matching to pour coordination:

• Terrastone Architectural Concrete: Perth-based experts offering design advice, swatch samples, integral colouring and dedicated project management. Visit one of their display centres across the metro area to see real-world examples.
• Independent contractors: May source materials on your behalf but vary in quality control, sample-approval processes and showroom access.

Partnering with a specialist installer guarantees rigorous testing, mock-up pours and a single point of contact to navigate approvals, scheduling and final handover.

Online vs In-Person Colour Selection

Digital tools and virtual visualisers enable quick exploration of potential hues, but they can’t fully replicate on-site lighting, texture and surrounding materials. To make the most informed choice:

• Use online colour selectors to shortlist your top three shades.
• Visit a display centre—such as Terrastone’s—to examine physical swatches in natural light.
• Request a small sample pour on your own site; this live mock-up remains the gold standard for confirming exactly how the finished surface will look.

Blending digital convenience with hands-on inspection ensures you order colour through concrete with confidence, avoiding unexpected variations and costly rework.

Specifying and Ordering Coloured Concrete

Getting your coloured concrete project off the ground starts with a clear, concise specification and a well-planned ordering process. Early collaboration with suppliers, a robust approval workflow for swatches and mock-ups, and a dedicated point of contact will keep your project on time and on budget. Below, we outline best practices to transform your design brief into the right mix, delivered when you need it.

Crafting a Detailed Specification Brief

A specification brief should capture every detail your supplier needs to reproduce the exact colour, texture and performance you’ve chosen. At a minimum, include:

• Project name and location
• Concrete grade (e.g. C25 or C32) and intended use (driveway, alfresco, pool surround)
• Colour code and pigment dosage (for example, 3% Terrastone Shell oxide)
• Finish and texture (honed to 0.5 mm aggregate exposure, broom finish, polished)
• Slab thickness and joint layout (100 mm slab with saw-cut joints at 3 m centres)
• Required additives (UV inhibitor, water-repellent admixture)
• Compliance standards (AS 1379:2017, AS 3600:2018)

Example specification excerpt:

Project: Smith Residence, Wembley Downs  
Concrete Mix: C32/40, max. w/c ratio 0.50  
Colour: Terrastone Shell (Pigment Batch #0457), dosage 3% wt. cement  
Finish: Honed finish exposing 0.7 mm aggregate  
Thickness: 120 mm slab with control joints at 3 m centres  
Admixtures: UV inhibitor (0.5% by weight), water-repellent additive  
Standards: AS 1379:2017 compliance required  
Delivery date: 15 July 2025, between 7–9 am

Detailing these elements up front reduces the chance of misinterpretation and helps suppliers prepare accurate quotes and delivery schedules.

Understanding Lead Times and Minimum Quantities

Most ready-mix suppliers set minimum order quantities to ensure efficient batching:

• Boral Colori®: 2–3 m³ minimum, 48-hour notice
• Dulux Avista Colour Through: from 5 m³, 3–5 business-day lead time
• CCS Full Depth: 1 m³ minimum, often 24-hour turnaround

Pigment-only suppliers like Concrete Colour Solutions or Premix may require larger bulk orders (e.g. 25 kg bags or 1 T bulk). Small-volume jobs can incur higher per-kilogram costs, so bundling multiple pours or arranging shared orders with neighbouring sites can offer savings. Lock in your delivery slot as early as possible—peak building periods tend to book out quickly.

Swatch Approval and Sample Pours

Digital renderings are useful for initial selection, but nothing replaces seeing your colour in situ. Follow this two-step approval process:

1. Order physical swatches from your decorative concrete specialist. View these on-site at different times of day, alongside adjacent materials like brickwork or decking.
2. Request a small sample pour using your final mix design and pigment dosage. This live mock-up, cured under actual site conditions, confirms the exact hue, finish and texture. Once you and your builder sign off on the panel, it becomes the benchmark for all subsequent pours.

Retaining these approved swatches and panels ensures any future top-ups or repairs match perfectly, avoiding costly colour mismatches.

Collaborating with a Project Manager

A single point of contact—such as Terrastone’s dedicated project manager—streamlines communication and accountability. Your project manager will:

• Coordinate mix design reviews and sample-pour scheduling
• Liaise with batching plants to confirm pigment batch numbers and delivery windows
• Oversee on-site QA/QC checks during pouring and finishing
• Manage any variations or additional pours, armed with approved documentation
• Serve as your go-to for queries, progress updates and handover procedures

By entrusting these tasks to a dedicated professional, you minimise the risk of delays, misunderstandings or specification drift, ensuring your coloured concrete installation proceeds smoothly from brief to final finish.

Installation Best Practices and Maintenance Tips

A flawless finish isn’t just about colour selection and mix design—it relies on meticulous installation and ongoing care. Following proven best practices during site preparation, curing and sealing will protect your investment and keep that vibrant hue looking fresh for years. Below, we outline the key steps to install, protect and maintain your colour through concrete surface.

Site Preparation and Subgrade Requirements

Before concrete even arrives on site, ensure you’ve built a solid foundation. A well-prepared subgrade and base layer minimise settlement and cracking, preserving both colour consistency and structural integrity.

• Compacted Base: Excavate to the required depth and compact the subgrade to a minimum 95% standard Proctor density.
• Drainage: Verify falls of at least 1–2% away from the home or pool edge to prevent standing water. Install subsoil drains or gravel layers if the area is prone to waterlogging.
• Edge Restraints: Secure formwork or concrete edge restraints firmly in place to maintain slab geometry and avoid “pop-outs” at corners. Use treated timber, steel formwork or permanent kerbing depending on your design.

Taking these preparatory steps ensures your coloured concrete slab can resist ground movement, moisture fluctuations and edge spalling over its life.

Proper Curing and Finishing Techniques

Correct curing locks in strength and helps pigments mature to their intended shade. Conversely, poor curing can lead to surface crazing, reduced durability and uneven colour.

• Wet Curing: Keep the slab damp for at least seven days by mist-spraying or covering with wet burlap, hessian or plastic sheeting.
• Curing Compounds: If water curing isn’t feasible, apply an approved curing compound within two hours of final trowelling. Ensure full, even coverage to seal in moisture.
• Curing Blankets: In cooler months or windy conditions, blanket the concrete immediately after finishing. This prevents rapid moisture loss and thermal shock, which can dull the final colour.

During the finishing phase, avoid overworking the surface. Strike off and bullfloat gently, then finish with a power trowel or hand trowel at the correct timing—once bleed water has dissipated but before the mix hardens.

Sealing and Protecting Coloured Concrete

A quality sealant not only enhances colour depth but also forms a barrier against stains, UV exposure and moisture ingress. Selecting the right sealant and maintenance schedule is crucial.

• Topical Sealers: Provide a glossy or satin finish, boosting colour vibrancy. Ideal for alfresco and pool surrounds. Reapply every 2–3 years depending on traffic.
• Penetrating Sealers: Maintain a natural look while repelling water and oils. Best suited to driveways and exposed aggregate finishes. Typically require less frequent upkeep—every 3–5 years.
• Application Tips: Apply sealers when the concrete has cured for at least 28 days. Use a roller or low-pressure sprayer, following the manufacturer’s coverage guidelines. Avoid sealing in direct sunlight or during rain.

A well-maintained seal extends the life of your colour through concrete and makes routine cleaning far simpler.

Cleaning and Upkeep Recommendations

Routine cleaning prevents dirt buildup and preserves the aesthetic of your coloured surface. A gentle approach is all that’s needed to keep things looking sharp.

• Regular Sweeping: Remove loose dirt, leaves and debris with a push broom.
• Gentle Washing: Use a hose or low-pressure washer (under 1,300 psi) with a pH-neutral detergent for stubborn spots. Rinse thoroughly to avoid residue.
• Stain Treatment: Address oil or grease spills promptly. Apply a poultice or mild degreaser, scrub lightly and rinse.
• Avoid Harmful Products: Steer clear of acidic cleaners, abrasive powders and de-icing salts. These can etch the surface or strip sealants.

By combining proper installation methods with straightforward maintenance, your integral-colour concrete will continue to be a durable, low-maintenance feature of your home—one that stays true to its original tone and texture for years to come.

Frequently Asked Questions About Full-Depth Colouring

Is Integral Colouring Suitable for All Projects?

Integral colouring works well for a wide range of concrete applications—from residential driveways and patios to pool surrounds and commercial flooring. It’s especially advantageous where durability and uniform colour are priorities. However, if your project calls for highly detailed surface patterns (like intricate stencilling) or extremely fine textures, you might combine integral pigments with surface treatments. For very small jobs, consider that minimum order quantities for coloured mixes can be higher than for plain concrete, so factor that into your decision.

How Long Will the Colour Last?

When pigments are mixed through the full depth of the slab, colour permanence is exceptionally high. Under Perth’s harsh sun, you can expect the original hue to remain true for decades if the surface is properly sealed and maintained. A quality topical sealer every 2–3 years, or a penetrating sealer every 3–5 years, will lock in pigments and protect against UV exposure. Compared with stains or painted coatings—which often need reapplication every few seasons—integral colour is a long-lasting solution.

Can Damaged Areas Be Repaired?

Yes. One of the benefits of full-depth colouring is that any patch or extension can match the existing slab colour exactly. To achieve a seamless repair:

1. Refer to your original mix design and pigment dosage.
2. Use the same aggregates, cement grade and admixtures.
3. Prepare a small test patch to verify the match under site conditions.
4. Feather the edges of the repair and finish it with the same trowelling or broom technique.
   Because the pigment runs through the entire layer, minor chips or cracks blend in once patched correctly.

What Are the Cost Differences?

Integral colouring typically carries a premium of around 10–20% over standard grey concrete, reflecting the cost of pigments and tighter quality controls. Shake-on colour hardeners and premium stains may be slightly less expensive upfront, but they only colour the surface and often require reapplication or touch-ups over time. In contrast, integral colouring’s lower maintenance requirements can deliver better value over the lifespan of your slab. Always compare quotes on a per-square-metre basis and include projected maintenance costs when evaluating your options.

Bringing Colour Through to Life

Full‐depth colouring turns concrete from a functional building material into a lasting design feature. By integrating pigments throughout the slab, you get uniform, fade-resistant hues that stand up to Perth’s harsh climate and heavy use. From pigment selection and precise batching to finishing, sealing and maintenance, every stage contributes to a high-performance surface that retains its vibrancy for years.

Whether you’re aiming for a statement driveway, a cohesive alfresco zone or a cool, safe pool surround, integral colouring offers unmatched durability, low upkeep and design flexibility. The process is underpinned by Australian standards, rigorous quality control and a clear specification brief, so you can be confident in both aesthetic and structural results. And with Terrastone’s dedicated project management, sample-approval workflow and local display centres, bringing full-depth colour to your home is straightforward and stress-free.
