KEIM Mineral Coating for Glaze Repair

Henry Frerk Sons offers potassium silicate coating systems from Cathedral Stone and Keim Mineral Coatings. Silicate coatings are the premier restoration coating system for historic masonry, and they offer long lasting, breathable finishes that can be custom matched to replicate almost any historic masonry finish. Silicates chemically bond with the masonry substrate, so there is no flaking or peeling, and when they eventually fade, they can be easily recoated.

Our Mineral Coating KEIM Products

Potassium silicates are also recommended for brick, stone, and concrete restoration. Additionally, Keim mineral coating products offer an interior finish, Optil, and silicate paints for murals and decorative purposes. Silicate coatings can be color-matched to a sample or to most Benjamin Moore or Sherwin William colors. (Due to the mineral pigment systems some colors cannot be replicated.) Keim also offers a full palette of colors, including metallics.

Concretal Pigmented Mineral Stain for Concrete

Concretal Pigmented Mineral Stain for Concrete

Concretal stain is the ideal solution for unifying uneven or variable concrete finishes and can be used to ensure that the required finish can be delivered to the client’s or specifier’s standard, without looking like a painted surface. The translucent mineral silicate stain’s remedial applications are only a small part of their design versatility, as it also offers a wide range of colors to decorate concrete, without changing the raw concrete’s texture and finish.
