Coloured Concrete Finishes in South Brisbane and Logan

What Is Coloured Concrete?

Coloured concrete uses iron oxide pigments to transform standard grey concrete into a surface that complements your home and landscape. The colour can be mixed through the entire slab (integral colour) or applied as a surface hardener during finishing.

Unlike paint or coatings that sit on top and peel, integral colour becomes part of the concrete itself. The result is a clean, modern finish that holds its tone for decades with basic care.

How We Apply Coloured Concrete

At Bunce Concrete, David tailors the colouring method to each project. For most residential driveways and outdoor entertaining areas, integral colour is the preferred approach.

We batch the oxide pigment directly into the concrete mix at precise ratios. Consistency matters here. Too little pigment and the colour looks washed out. Too much and you waste material without improving the result. David’s 18 years of concreting experience means he knows the right ratios for every colour in the range.

After pouring and screeding, we finish the surface with steel trowels or brooms depending on the texture you want. A smooth trowelled finish gives a sleek, contemporary look, while a broom finish adds grip for pathways and sloping areas.

Once cured, we apply a clear sealer that protects the surface and brings out the richness of the colour.

For projects where you want a bolder or more intense colour, David may recommend a dry-shake colour hardener. This is broadcast onto the wet concrete surface and trowelled in, creating a dense, hard-wearing top layer with concentrated colour.

Performance in Queensland Weather

South-east Queensland’s combination of intense UV, heavy rain, and humidity can test any outdoor surface. Coloured concrete handles these conditions well when installed correctly.

The iron oxide pigments we use are inorganic and will not break down under UV light the way organic dyes can. Proper curing and sealing protect the surface from moisture penetration, which is the main cause of discolouration and efflorescence in subtropical climates.

For areas exposed to standing water, such as pool surrounds, David ensures adequate fall and drainage so the surface dries quickly after rain.

What Affects the Cost

Your coloured concrete quote will depend on several factors:

• Colour method — integral colour is more economical than colour hardener for large areas
• Slab area and thickness — standard residential is typically 100mm, but driveways may need more
• Pigment intensity — darker colours require more oxide, which adds to material costs
• Site conditions — access, slope, soil type, and demolition of existing surfaces
• Finish texture — trowelled, broom, or combined finishes affect labour time

David quotes every job after an on-site inspection to give you an accurate, fixed price.
