511 Porous Plus Sealer

Porous Plus Penetrating Sealer is designed to seal and protect most interior/exterior porous surfaces, including GFRC concrete, natural stone, granite, marble, quartz, travertine, limestone, slate, grout and more. Premium surface sealer forms an invisible, protective barrier that resists weather, oil, weather and stains with advanced, non-slip protection. 511 Porous Plus does not coat the surface and will not change the natural look of treated surfaces.
