Cityshine — Sydney's natural stone specialist
Natural stone is one of the most premium materials you can put on your property — and one of the most misunderstood when it comes to care. Generic outdoor cleaners damage stone. Generic sealers either fail too fast or trap moisture and cause more harm than good. Stone needs care from people who know stone.
Cityshine has been cleaning, restoring and sealing Sydney's natural stone for over 20 years — for residential homes, commercial buildings, councils and heritage projects. Every stone type needs a different approach; we know which products work, which to avoid, and how to deliver results that last.

What goes wrong without proper stone care
- Acid etching — most household cleaners are acidic and damage stone irreversibly
- Salt damage — particularly on stone near pools and the coast
- Biological growth — moss, algae and lichen love natural stone
- Failed sealers — generic sealers either fail fast or trap moisture and cause efflorescence
- Surface erosion — softer stones (sandstone, limestone) lose material faster than harder stones
- Honing wear — polished stone can lose its finish over time and need rehoning

What proper stone sealing delivers
- Stain and etch protection — sealed stone resists the everyday spills (wine, oil, citrus) that destroy unsealed stone
- Biological growth prevention — especially valuable on outdoor stone
- Salt and water damage protection — critical near pools and the coast
- Restored and protected colour — natural stone's character preserved
- Surface life extended significantly — properly sealed stone lasts decades
- Heritage-appropriate care — for surfaces that require it
FAQ
- How often does sealed stone need resealing? 3–8 years depending on stone type, location and exposure. We provide a tailored maintenance plan after every job.
- Will sealing change how my stone looks? You choose — natural penetrating, colour-enhancing, or wet-look finishes.
- Can you remove old, failed sealer? Yes — stripping old coatings is often the first step of a proper resealing job.
- What about heritage stone surfaces? We're experienced with heritage stone and use reversible, stone-respecting treatments where required.
- What products should I never use on stone? Acid cleaners (vinegar, citrus-based, bathroom cleaners with acid), abrasive scrubbers, generic outdoor cleaners not rated for stone. We provide a personalised care guide.
