Vitro-Shield (Maintenance) is a ready-to-use (RTU) water-based semi-topical hard finish that improves reflectivity while increasing the stain and wear resistance of polished concrete. Vitro-Shield Maintenance provides a much harder, longer lasting finish than typical floor waxes and doesn’t require stripping to be reapplied. Vitro-Shield Maintenance is also recommended to be used in applications where dyes have been applied, to seal in color. Concrete requiring additional hardness, a thin application of Vitro-Crete (LM) can be applied prior to Vitro-Shield Maintenance.
