Concrete stain

Concrete Staining & Colour

Concrete stain is how you colour the slab itself, not paint sitting on top. We apply acid stains for that variegated, translucent look, and water-based dyes when you want a saturated, uniform colour, then seal to lock it in.

Where this works

  • Retail & hospitality floors
  • Residential open-plan slabs
  • Feature walls & fireplaces
  • Restored industrial floors
  • Outdoor concrete patios (UV-stable dyes)

How we install it

  1. 1
    Open the surface

    Existing sealers or coatings must come off. New slabs need to be at least 28 days old and lightly acid-etched or diamond-ground so the stain can penetrate.

  2. 2
    Apply stain

    Acid stains are applied with a sprayer and worked with a nylon brush to encourage variegation. Dyes are applied evenly for saturated colour.

  3. 3
    Neutralise & rinse

    Reactive stains are neutralised with a baking-soda wash and rinsed until pH-neutral. This stops residues fighting the sealer.

  4. 4
    Seal

    Penetrating sealer for a natural matt look, or acrylic / polyurethane top coats for higher sheen and stain protection.

Common pitfalls we prevent

Blotching from residual curing agents — solved by grinding the slab before staining
Colour bleeding when mopped — cured by neutralising properly before sealing
Acid stain used on a slab too young or too dense — stain won't take; solved with a mock-up on the actual slab

Frequently asked

Can I use concrete stain outdoors?+

Yes with the right chemistry — UV-stable water-based dyes and acid stains both work outdoors, sealed with a UV-stable acrylic. Not solvent-based dyes.

How long does a stained floor last?+

The colour is in the slab itself and doesn't fade. The sealer wears — expect to re-seal a domestic floor every 5–7 years, and a commercial floor every 2–4 years depending on traffic.

Can you stain over an old coating?+

No. The old coating has to be diamond-ground off first. That's part of the quote.
