+Integral colour or colour hardener, what is the difference?
Integral colour is oxide mixed in before pouring, colouring the whole slab through its depth. Hardener is broadcast onto the surface afterwards and worked in, giving a denser, more wear resistant top layer along with the colour. Hardener often suits a heavy traffic driveway better.
+Will it fade over time?
Some gradual UV fading is normal over many years in direct sun, the same as most exterior surfaces. Sealing slows this considerably and is worth doing from the start, then reapplying every few years to keep the tone fresh.
+Can you match my existing coloured driveway?
We can get close with the same oxide product and ratio, but an exact match to concrete that has already weathered for years is difficult. For an extension we usually recommend a deliberate joint line rather than promising an invisible match.
+Does it cost much more than plain concrete?
Yes, there is a premium for the oxide or hardener and the more careful finishing needed for an even tone, but it is a modest increase for the visual difference it makes.
+Can it be combined with a broom or aggregate finish?
Yes, very commonly paired with a broom texture for grip, or used as the base tone under an exposed aggregate wash. See our exposed aggregate and stamped concrete pages for how that works.
+Does it need extra maintenance?
Not really beyond normal concrete care. Resealing roughly every three to five years protects the colour and keeps the surface easier to clean, the main difference from plain grey concrete.
+What colours are popular here right now?
Charcoal and graphite on newer coastal style builds around Papamoa and the Mount, warmer sand and oatmeal tones on older character homes further inland. We bring samples so you see the real finish before deciding.
+Can I use two colours in one slab?
Yes, a contrasting border or band is a common way to frame a driveway or patio, using a saw cut or tooled joint to separate the colours cleanly rather than letting them bleed together.
