At Sir Grout Westchester we understand most natural stone surfaces are porous, and if left exposed, will absorb water, dirt and other fluids such as grease, oil, wine, etc. A high-quality Cortland Stone sealing treatment will save your stone from exposure, and protect the luster of the natural grain or finish of your stone, no matter the type.

Cortland Stone Sealing New York:


Sir Grout's unique water-born polymer sealant, Tile Armor, prevents soil penetration into stone, giving maximum protection. The striking stone surface's look will not be altered by this non-flammable, odorless sealer. This Tile Armor treatment, provided by Cortland stone sealing specialists, insures preservation against stains and dirt penetration for 12-18 months. The surface of polished stones will be saved without altering their striking appearance.
Our Cortland Stone Sealing Service for cleft stones is a case-by-case service designed to treat the unique needs of cleft stones such as various slates and quartzite. Due to their level of exposure, these stones may require other types of sealants to protect and return luster to the stone surfaces. These stone surfaces will be treated under expert Cortland stone sealing advisement by our Slate and Cleft Stone Treatment.
