Keim Mineral Silicate Coatings

A range of mineral silicate coatings designed for long-life protection of mineral substrates, offering high vapour permeability, colour stability, and proven exterior durability.

Keim Mineral Silicate Coatings are sustainable, waterborne liquid silicate paints that chemically bind to mineral substrates to create an exceptionally durable and vapour-permeable breathable finish. These coatings provide long-term resistance to weathering, UV exposure, airborne pollutants, and acidic environmental conditions while maintaining a natural mineral appearance.

The systems are engineered for masonry, concrete, and other mineral bases, making them suitable for both heritage restorations and contemporary construction. Their high breathability supports moisture management within mineral substrates, reducing the risk of blistering or peeling associated with film-forming coatings. Keim coatings are low-maintenance, colourfast, and available in a wide range of mineral-based colours through the Keim Palette.

These mineral silicate systems are used for façade renovation, concrete protection, and projects requiring long-term sustainability, natural appearance, and compatibility with mineral surfaces.

Additional Information

Mineral silicate coatings rely on a chemical reaction (liquid silicate binding) with mineral substrates. Proper substrate assessment is essential to ensure compatibility and long-term adhesion. These systems maintain breathability and do not form a film, reducing the risk of blistering. For full preparation requirements and system build-ups, refer to the relevant Equus Keim technical literature.
