Coval Polished Surface Sealer is a clear, breathable, water- borne sealer designed for use on interior or exterior polished natural stone surfaces, including granite, marble, onyx, quartzite, limestone, travertine and serpentine. Polished Surface Sealer is a long lasting barrier that provides superior resistance to water and stains. Coval Polished Surface Sealer does not protect against acid-etching on calcium based stones (No sealer does). See Stone Coat Data Sheet for protection against acid etching and staining on marble, limestone, travertine and onyx.
Coval Polished Stone sealer is extremely easy to apply and does not leave a film or haze. It can be reapplied as necessary without complication.
