When people think of polished concrete, they often picture a cold industrial grey. But modern techniques allow for a wide variety of colours — from warm stone tones to rich charcoals and even deep reds or greens. Whether you’re after subtle natural variation or a bold design statement, there’s a finish to match.
Colour in polished concrete can be created through one of three main methods: coloured aggregates (stone), integral pigments added to the concrete mix, or surface-applied dyes. Each option offers different aesthetics, permanence, and control.
| Method | Appearance | Longevity | Control |
|---|---|---|---|
| Natural Cement Grey | Warm or cool greys, slight variation | Permanent | Moderate – depends on cement and stone |
| Coloured Aggregates | Speckled or flecked effect | Permanent | High – visible after exposure |
| Integral Pigments | Uniform colour throughout slab | Permanent | Very high |
| Surface Dyes | Vibrant colour or translucent tone | Moderate (needs resealing) | Very high |
These are the most requested colours in residential and commercial polished concrete projects across the UK.
The classic polished concrete tone — light to mid-grey with subtle variation depending on mix, finish, and lighting. Works in almost any setting from minimalist to industrial.
Bold, dark, and modern. Charcoal is a dramatic choice best suited to larger spaces with good lighting. Often achieved with black dye or heavily pigmented mixes.
A brighter take on grey that pairs well with Scandinavian or contemporary interiors. Reflects light better than darker tones and feels more open in small spaces.
Warmer, natural tones often chosen for residential interiors. Popular in combination with exposed stone or timber. Usually achieved with earthy pigments.
Ultra-modern and bright. Requires white cement, light aggregate, and care during install to avoid staining. Best sealed with a non-yellowing matte finish.
Warm red-brown tones used in rustic and Mediterranean spaces. Achieved through both pigmented mixes and surface dyes.
Deeper than charcoal with bluish undertones. Often chosen for luxury retail spaces or dramatic contrast zones.
Used sparingly in feature zones or with tinted microcements. Offers earthy or jewel tones depending on base mix and dye concentration.
Used in hospitality or creative interiors for warmth and richness. Typically achieved with transparent surface dyes.
From soft pastels to bold industrial tones, custom mixes are possible using integral pigments or layered dye systems. Always test a sample before full pour.
Decide whether you want to use a pre-coloured mix (integral pigment), expose coloured aggregates, or apply a dye during polishing. Each has its own process and effect — and not all are suitable for overlays.
Always request a sample panel or test area. Colours can look dramatically different depending on lighting, surface porosity, and sealer type.
Integral colour is added at the batching plant and poured as usual. Dyes are applied after grinding, before sealing. Aggregate colour depends on the polish depth — deeper cuts reveal more stone.
The final step locks in the look. Choose a non-yellowing, UV-resistant sealer for dyed finishes. For natural grey or pigment, a matte or satin finish gives the best visual clarity.
