Zirconia QuartzSeal™ is a penetrating, chemically bonded, inorganic sealant that when applied over CeramycGuard™ further inhibits water and chemical pollutants. The “near zero porosity” inorganic glass-layer finish helps seal out dust, dirt and protects against stains. Rising to the surface of QuartzSeal™ is a dense layer of electrostatically charged nano-swords that prevent microbial occupation and create a Biological Impervious™, super clean surface.
