Colour & design

Colour follows the concrete’s character

Translucent colour brings the slab into the design rather than hiding it. Repairs, aggregate and absorbency remain part of the picture. Set out the pattern on a drawing, but approve the colour on the actual concrete, including a representative repair and the intended protective finish.

Colour can make a concrete floor part of the interior design or distinguish functional areas. C² Tint penetrates and colours suitable interior concrete and adds depth to polished finishes. It is translucent: the base concrete, repairs and preparation still affect the final result. It should not be presented as an opaque paint that hides defects.

What the crew brings to site

A concrete grinder does the cutting when the surface needs levelling or deeper aggregate exposure. An edge grinder reaches walls and columns. The machine and tooling are selected together for the slab, not simply by motor power.

On suitable surfaces, C² Power Polish offers another route: C² Diamonds resin discs fitted to compatible power trowels, scrubber-dryers or swing machines. Check the mounting, speed and wet/dry compatibility before starting. A finishing system is not a substitute for deep stock removal.

The less glamorous kit matters too: appropriate dust extraction for dry work, slurry collection for wet work, a scrubber-dryer for cleaning between stages, a low-pressure sprayer and clean microfiber applicators. Keep clean tools separate from the grinding area.

Read the surface, then choose the disc

Think of a disc number as a step, not a promise of gloss. Coarser tooling opens the surface; finer tooling refines the scratches it leaves. Metal-bond tools are used for removal, while resin tooling develops the finish. Concrete hardness, the tool bond and the machine all influence the cut. Choose the initial grit on a trial area and check tool wear early; do not copy a sequence from another slab blindly.

The route for this floor

The referenced C² Tint route begins with refinement equivalent to #200 resin diamonds, followed by cleaning and drying. Apply with a low-pressure sprayer and microfiber applicator, working evenly without puddles. If further polishing is specified, the Tint sheet describes a dry #400 stage and its cleaning and colour steps. Densifying follows colouring in this system. Read the supplied Tint formulation’s complete sequence before deciding the programme; do not insert a standard uncoloured-floor sequence halfway through.

What a good pass looks like

Work in manageable areas with even, overlapping passes. At each change of abrasive, remove loose grit and inspect a clean patch under low-angle light. A remaining coarse scratch needs attention now: a finer disc may make the surrounding concrete shine without removing it. Treat the perimeter to the same visual standard as the middle. Machine speed, pressure and travel rate come from the equipment and tooling instructions, then are confirmed on the test area.
