Expert Stone Sealing & Treatments for Lasting Protection and Longevity
Stone Lab is New Zealand’s specialist in stone treatment, sealing, and protection. Trusted by homeowners, builders, and architects, we use premium Italian products and eco-friendly technology to protect and preserve all natural and engineered stone.
Our treatments enhance durability, control moisture, and prevent salt and organic damage, all while maintaining your stone’s natural beauty and breathability.
With decades of experience and a passion for craftsmanship, Stone Lab delivers long-lasting, sustainable results for every surface.
Anti-Graffiti Stone Protection Coatings
Our anti-graffiti coatings prevent paints, sprays, and ink from penetrating porous surfaces such as natural and artificial stone, brick, terracotta, concrete, and plaster.
These near-invisible, non-film-forming coatings preserve your stone’s natural look while reducing mould growth and dirt buildup, making cleaning faster and easier.
We proudly use Geal Systems: world-renowned Italian stone care products used on projects like the Museum of Modern & Contemporary Art (Italy), the NZ Police Hub (Cambridge), and the Wellington ANZAC Memorial.
Benefits include:
Minimal visual impact maintains natural colour and texture
Suitable for all absorbant materials
Long-term protection, even after outdoor exposure
