ProtectGuard HD is a professional-grade sealer engineered for low-porosity surfaces like granite, honed bluestone, polished concrete, and engineered stone. This water-based treatment penetrates deep without forming a visible film, creating long-lasting resistance to water, oil, dirt, and even graffiti.
Trusted by installers and surface care pros, it’s the go-to sealer for high-traffic, exposed, or premium surfaces where durability matters — and aesthetics must stay true.
Perfect for new builds or restoration projects, indoors or out, ProtectGuard HD enhances durability, slows ageing, and makes ongoing cleaning much easier — without darkening or altering the finish.
Why Use ProtectGuard HD:
✔️ Long-term protection from oil, water, and everyday stains
✔️ Anti-graffiti properties for walls, facades, and commercial sites
✔️ Invisible — won’t alter the natural colour or finish
✔️ Breathable — lets moisture escape without trapping it inside
✔️ UV- and frost-resistant — built for tough Aussie conditions
Ideal For:
