Permanent Reactive Colour with Genuine Character
Acid-stained concrete is one of the most distinctive finishes available for both new and existing slabs. Unlike paint or surface coatings that sit on top and eventually peel or chip, acid staining works through a chemical reaction — the diluted acid solution reacts with the minerals naturally present in the concrete, producing permanent, variegated colour that's locked into the slab itself. The result is a surface that looks like natural stone, aged leather, or burnished earth — and no two results are ever identical.
Our Adelaide Acid-Stained Concrete service is popular for both indoor floors and outdoor surfaces where a natural, organic look is the goal. It works on new concrete pours and on existing slabs in suitable condition, making it a cost-effective way to dramatically transform the appearance of a space without ripping up and replacing the concrete. The colour palette is primarily earthy — deep browns, warm ambers, olive greens, and blue-grey tones — which works beautifully in homes styled around natural stone, exposed timber, and organic landscaping.
The unique, one-of-a-kind character of acid-stained concrete is both its signature and its appeal. The variation across the surface — darker in some areas, lighter in others, with subtle mottling and depth — gives it a richness that painted or pigmented surfaces simply can't replicate. If you want a floor or outdoor surface that genuinely looks like it has history and character, acid staining is one of the best tools available.
Our Process
1. Consultation & Surface Assessment
We inspect the existing slab or new pour, assess porosity and condition, and walk you through the colour and pattern possibilities for your specific surface.
2. Surface Preparation
The surface is cleaned, degreased, and any sealers or coatings are removed — acid stain only penetrates raw, open concrete, so preparation is critical to a quality result.
3. Acid Stain Application
We apply the acid stain solution in multiple passes, allowing it to react chemically with the concrete minerals. The result is a permanent, variegated colour that's unique to each slab.
4. Neutralising, Sealing & Protection
The surface is neutralised to stop the chemical reaction, thoroughly cleaned, then sealed with a premium-grade product to protect the finish and bring out the depth and richness of the tone.
Why Choose Acid-Stained Concrete

Frequently Asked Questions
What colours does acid staining produce?
Acid staining produces rich, earthy tones — deep browns, warm ambers, burnt sienna, olive greens, and blue-grey tones depending on the minerals in the concrete. The colours are subtle and variegated rather than flat and uniform, giving the surface a natural stone-like depth.
Can acid staining be done on any concrete slab?
Most concrete slabs can be acid stained, but results depend on the slab's condition and mineral content. Old sealers, oils, or contamination must be removed first. We assess the slab before committing to ensure the result will meet expectations.
Is acid staining safe?
The acid staining process uses diluted hydrochloric acid and requires proper protective equipment and ventilation. Once the surface is neutralised, cleaned, and sealed, the finished surface is completely safe for everyday use.
How long does acid-stained concrete last?
Because acid staining is a chemical reaction with the concrete itself — not a coating applied on top — the colour is permanent and won't peel or chip. With proper sealing and periodic reseal maintenance, the finish lasts the life of the slab.
