Fast Shipping Dispatched within 2–3 business days Australia-wide.
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.
