Question 1

What is coloured concrete and how is it made?

Accepted Answer

Coloured concrete uses iron-oxide pigments — either mixed directly into the wet concrete (integral colour) or applied as a surface hardener during finishing. Integral colour runs through the full depth of the slab, so chips and scratches do not expose grey concrete beneath. It is available in dozens of custom shades.

Question 2

Does coloured concrete fade over time in Adelaide?

Accepted Answer

Integral coloured concrete is UV-stable and resists fading significantly better than surface-applied colours. Sealing with a UV-resistant penetrating sealer every 3–5 years maintains colour depth and prevents surface chalking caused by Adelaide's intense summer sun. Lighter colours show less variation from UV than darker tones.

Question 3

How does coloured concrete compare to exposed aggregate?

Accepted Answer

Coloured concrete delivers a smooth, uniform surface with rich colour throughout the mix — ideal for a clean, modern look. Exposed aggregate provides a textured surface with natural stone visible. Coloured concrete is typically 10–15% less expensive than exposed aggregate and suits contemporary architectural styles.
