Mineral silicate stains and pure mineral repair mortars for truly compatible restoration solutions

Professionals have been choosing Keim for over 140 years to protect some of the most important historic masonry in the world. You, too, can select mineral silicate stains that are renowned for their durability and longevity. Stains penetrate and form permanent bonds with stone masonry, and are extremely vapor permeable, which makes them ideal for decorating and preserving stone. Mineral-only repair mortars are ultimately compatible and ensure in-kind repairs that have properties to match those of native stone. From deep, structural repairs, to minor face-lifts, KEIM has you covered! 

Repairs that last as long as the original stone.
