Plain grey concrete is a great floor, but it's not the only option. Colour opens up polished concrete as a genuine design element rather than just a practical surface. The right dye or stain can transform a utilitarian slab into a warm, distinctive floor that works with your furniture, your light, and the character of your home or business. This guide covers the main colouring methods, how they interact with Kamloops' natural light, and how to make a colour decision you'll be happy with in five years.
The two main approaches to coloured concrete
Concrete dyes
Concrete dyes are fine solvent-based or water-based pigments that penetrate the concrete surface. They produce bright, consistent colour with a translucent quality — you can still see the aggregate and character of the concrete through the colour, which is part of what makes dyed concrete look different from painted concrete. Dyes are UV-sensitive, meaning they can fade with direct sunlight exposure over time if not protected with a UV-stable sealer. For interior floors, UV is rarely a concern. For covered exterior areas, we specify UV-stable products.
Acid stains
Acid stains are reactive — they chemically react with the calcium hydroxide in the concrete to produce a permanent colour change that can't be removed. The result is characteristically mottled and variegated, with no two floors looking alike. Earth tones dominate: ambers, bronzes, deep greens, and warm browns. If you want a uniform, consistent colour, acid stain isn't the right choice — its strength is that organic, aged look that some spaces suit beautifully. It's also less predictable than dye, because the reaction depends on the exact mix composition and curing conditions of the original slab.
Which colouring method is right for your project
- Want a specific, consistent colour? Use a dye. Greys, charcoals, warm taupes, blues, and greens are all achievable with good colour consistency across the floor.
- Want a one-of-a-kind, organic, mottled look? Acid stain delivers that in a way no other method can replicate.
- Want a marbled or flowing metallic look? That's a metallic epoxy system rather than a stain — a different process entirely, applied as a coating over the slab.
- Want subtle colour to warm up grey concrete? A light dye application in a warm tone (wheat, amber, or buff) takes the industrial chill off polished concrete in a living space without making it look obviously coloured.
How Kamloops light affects colour
This is a detail most people don't consider until they see a sample on their actual floor. Kamloops has intense direct sunlight in summer, long evening shadows in the valleys, and bright winter light at low angles. All of this affects how a colour reads in your space. A cool grey that looks sophisticated in an overcast Vancouver showroom can look washed out in our bright summer sun. A warm amber that looks muddy in a sample chip can come alive in the golden evening light that hits west-facing rooms in summer.
This is why we test colour on your actual slab before we commit to a full application. A small area, viewed at different times of day, is the only reliable way to see how a colour will read in your specific space. We do this as a standard part of our colour consultation.
Colour palettes that work well in Kamloops homes
Warm greys and charcoals
The most popular choice, and for good reason. A warm grey polished floor reads as contemporary and neutral without the coldness of a pure cool grey. It works with most furniture finishes, holds up well as trends change, and looks great in both natural and artificial light. Different aggregate exposures give different characters: a salt-and-pepper grind with a warm grey dye has depth; a cream finish with the same colour is smoother and more uniform.
Earth tones: wheat, sienna, and amber
Earth tones work especially well in homes with timber elements, leather furniture, or a BC-vernacular aesthetic. A light amber or wheat dye warms the floor without making it look like a different material — it still reads as concrete, just warmer. In homes with exposed wood beams or timber framing, this colour direction pulls the space together.
Deep colours: charcoal, slate, and forest
A very dark polished floor is dramatic and works in spaces with high ceilings and good lighting. It shows dust more readily than a mid-tone, which is the main practical consideration. In a commercial setting like a boutique retail space or a high-end showroom, a dark polished floor with carefully placed lighting is striking. Residentially, it's best suited to smaller areas or rooms with excellent natural light.
The colouring process and what to expect
- 1The slab is ground and prepped to the right stage. Colouring happens after grinding but before the final high-grit polishing passes.
- 2We test the colour on an inconspicuous area or a sample board made from your slab's concrete and review it with you.
- 3Dye is applied and allowed to penetrate. Multiple layers can be built for deeper colour or a marbled effect.
- 4The colour is locked in with the densifier and then the final polish passes bring the shine.
- 5The sealer goes on last, protecting the colour and completing the floor.
Colour is permanent once it's sealed. That's a feature, not a bug — it means it won't rub off, flake, or fade under normal conditions. But it does mean the colour decision matters. We take the time to get it right before we go.
