Coloured Concrete Explained: Options, Process and Maintenance
Coloured concrete gives homeowners genuine design flexibility beyond standard grey — but achieving a consistent, long-lasting result takes more than just adding colour to the mix.
How Coloured Concrete Is Achieved
Coloured concrete is most commonly achieved by adding oxide pigment directly into the concrete mix before pouring, giving the colour genuine depth throughout the material rather than sitting only on the surface. This “integral” colouring method is the standard approach for driveways and slabs where long-term colour durability matters, since the colour doesn’t wear away as the surface experiences normal use.
Integral Colour vs Surface Application
Beyond integral colouring, surface-applied colour treatments (like colour hardeners or stains applied during or after finishing) offer another approach, sometimes used for specific decorative effects or where a particular finish look is desired. Integral colouring remains the more common, durable approach for standard driveway and slab applications, since the colour isn’t dependent on a surface layer remaining intact.
Colour Options
Oxide pigments are available across a genuinely wide range — muted greys and charcoals, warm earth tones, and various other shades that complement different home exteriors and design preferences. The right colour choice is a genuine aesthetic decision worth considering alongside your home’s existing palette, roofline, brickwork and landscaping.
Achieving Consistent Colour
Consistent colour across a whole pour depends on careful mix control — accurate, consistent oxide dosing and thorough mixing are essential to avoid patchy or inconsistent colour in the finished slab. This is another reason coloured concrete work benefits from an experienced contractor familiar with achieving reliable results, not just any standard concrete crew.
Maintenance Considerations
Like any concrete finish, periodic sealing helps protect coloured concrete’s appearance, enhancing and protecting the colour from UV fading and general wear over time. See our guide to concrete sealing for more on how often this is typically needed and why it matters, particularly for coloured surfaces where maintaining vibrant colour is often a specific priority.

Frequently Asked Questions
Does coloured concrete fade over time?
Some fading can occur with UV exposure over years, though proper sealing significantly slows this and helps maintain the colour’s appearance.
Is coloured concrete more expensive than plain concrete?
Yes, typically, reflecting the cost of the oxide pigment and the additional care needed to achieve consistent colour throughout the pour.
Can I choose any colour for my concrete?
Oxide pigments come in a wide range of options, though not every colour imaginable — your contractor can show you the available range to choose from.
Does coloured concrete need different maintenance to plain concrete?
The core maintenance (sealing, cleaning) is similar, though sealing arguably matters even more for coloured concrete to protect and maintain the colour over time.
Can coloured concrete be combined with exposed aggregate?
Yes — coloured and exposed aggregate techniques are often combined for a distinctive decorative finish.
