Description
KEIM Mineral Primer is a breathable interior sol silicate primer designed to prepare drywall, masonry, plaster, concrete, and previously painted surfaces for mineral paint systems. Fast drying and ultra low VOC, it creates a uniform mineral surface that improves adhesion, coverage, and overall finish quality while maintaining the vapor permeability essential to healthy wall assemblies. Particularly effective as a mineral bridge coat beneath limewash and silicate paints.
Uses
- New drywall and gypsum board
- Plaster and stucco
- Concrete and masonry
- Previously painted interior walls
- Surface preparation for mineral paints and limewash
- Interior walls and ceilings
- Projects prioritizing breathable, low toxicity materials
Why it works?
KEIM Mineral Primer uses sol silicate chemistry to create a mineral based bonding layer that integrates with the substrate rather than sitting on top as a conventional acrylic primer. This helps regulate absorbency across the surface, improves adhesion of subsequent mineral coatings, and reduces flashing and uneven sheen.
Its microporous mineral structure remains highly vapor permeable, allowing moisture to move naturally through the wall assembly while supporting mold resistance and healthier indoor air quality. Over previously painted surfaces, it creates the necessary mineral profile for proper limewash adhesion.
About Keim
Founded in Germany in 1878, KEIM is recognized as the original inventor of mineral silicate paint technology. Developed from potassium silicate chemistry pioneered during the reign of King Ludwig I of Bavaria, KEIM coatings are known for chemically bonding into mineral substrates to create exceptionally durable, breathable, and color stable finishes. Today, KEIM products are used globally across historic restoration, contemporary architecture, and high performance sustainable building projects.
