Can plain concrete be coloured later after it's poured?

Not in the same way as integrated oxide colour added at batching — but genuine options exist for existing concrete, including concrete stains and tinted sealers, which sit on or penetrate the surface rather than running through the material.

These surface-applied options give a genuinely different look and durability profile to true integrated colour — worth understanding this distinction if colour consistency and longevity matter to you.

A full resurfacing overlay is another genuine option if you want a result closer to true integrated colour on existing, structurally sound concrete — worth discussing with your contractor which approach suits your specific goals.
