The flagship of the Aether Shield series. Premium Guard is a multi-substrate polysilazane ceramic that bonds to glass, metal, masonry, and stone alike. Specified for high-value architectural assets and heritage structures where one specification has to cover the entire envelope.
Premium Guard is engineered to form covalent bonds with the disparate surface chemistries of glass, polished metal, raw masonry, and natural stone. The same canister, the same procedure, the same finish performance — across an entire architectural envelope.
Most Premium Guard deployments are anti-graffiti for transit and infrastructure. Spray-applied tags wash off with water-only cleaning, year after year, without surface damage.
Used on historic stone facades and architectural masonry where strip-and-replace would cause irreversible damage. Reversible chemistry, breathable surface.
For mixed-substrate assets — glass curtain walls bordered by stone bases bordered by metal trim — Premium Guard simplifies the spec, the procurement, and the maintenance schedule.
