Keim Interior 9463
KEIM Innostar is a premium interior mineral paint designed for walls and ceilings where a healthy, breathable, and highly refined matte finish is desired. Formulated using sol silicate technology, Innostar chemically bonds into the substrate rather than forming a plastic film on the surface. The result is a velvety mineral appearance with exceptional durability, light diffusion, and color depth. In many applications, only a single coat is required due to its ultra high opacity and coverage.

Why it works?+
Unlike conventional acrylic paints, KEIM Innostar uses mineral silicate chemistry that bonds into the substrate through a process called silicification. This creates a highly durable finish that resists peeling, flaking, and premature aging. Its mineral composition also allows the surface to remain vapor permeable, helping walls naturally regulate moisture and reducing the likelihood of trapped humidity or mold growth.
The finish has a distinctly architectural quality: mineral matte, softly luminous, and responsive to changing natural light throughout the day. Because it contains no added VOCs, solvents, plasticizers, preservatives, or biocides, it maintains extremely low odor during application and supports healthier indoor air quality.

About KEIM+
Founded in Germany in 1878, KEIM is widely recognized as the original inventor of mineral silicate paint technology. The company was established after Adolf Wilhelm Keim developed a durable mineral paint system inspired by the frescoes of Northern Italy and commissioned during the reign of King Ludwig I of Bavaria.
Today, KEIM remains one of the world’s leading manufacturers of mineral coatings, with products used on projects ranging from historic landmarks to contemporary architectural spaces. The company continues to focus on mineral based technologies emphasizing permanence, breathability, durability, and material health.
