Keim Mineral Paints: Breathable, Durable Coatings with Heritage Innovation
Keim Mineral Paints were first developed in 1878 and have since become synonymous with high-performance, eco-friendly exterior paint for historic buildings and modern architecture alike. Their unique mineral formulation uses potassium silicate as a binder, combined with lightfast natural pigments and mineral fillers. This results in a paint system that chemically bonds with mineral substrates, ensuring excellent longevity and resistance to weathering without peeling or blistering. It is ideal for listed buildings, lime render, and breathable construction systems where conventional paints may fail.
Unlike acrylic paints that form a film on the surface, Keim products penetrate the substrate and maintain full vapour permeability. This helps to reduce damp-related deterioration and supports the long-term integrity of buildings. Their non-toxic, solvent-free nature makes them an excellent choice for environmentally sensitive projects, particularly where low VOC and fire safety are critical. Their exceptional colour stability means the finish remains bright and consistent over time, even under prolonged exposure to light and weather conditions.
Keim Mineral Paints are also highly versatile. They can be applied to limewash, clay paint, mineral coatings, and even conventional emulsions and oil-based finishes with appropriate surface preparation. Their natural resistance to algae, mould, and dirt means less frequent maintenance is required, keeping façades and internal walls cleaner for longer. Whether restoring a historic landmark or delivering a sustainable modern finish, Keim offers a proven, practical, and environmentally responsible choice.
Frequently Asked Questions
What surfaces are Keim Mineral Paints suitable for?
Keim Mineral Paints are suitable for mineral substrates such as lime render, brick, concrete, and stone. With appropriate preparation, they can also be applied to previously painted surfaces, including those with acrylic, oil-based, limewash, or clay-based finishes. They are commonly used on both historic buildings and breathable wall systems in contemporary architecture.
How do Keim paints differ from conventional emulsion paints?
Unlike conventional emulsions, Keim paints chemically bond to the substrate, forming a long-lasting, breathable finish that doesn’t trap moisture. This helps prevent issues like flaking, blistering, and mould. Emulsions tend to form a film on the surface, whereas Keim products integrate into the wall, offering superior vapour permeability and surface durability.
Do Keim Mineral Paints require a primer?
In most cases, a Keim primer is recommended to standardise the surface’s absorbency and promote adhesion. The type of primer depends on the substrate and its condition. For example, Keim Contact Plus is suitable for previously painted surfaces, while Keim Fixativ is used to stabilise porous or friable mineral backgrounds.
Are Keim paints environmentally friendly?
Yes, Keim Mineral Paints are manufactured without solvents or synthetic binders. They are low in VOCs, non-toxic, and fully mineral-based, making them ideal for sustainable construction and indoor air quality-conscious projects. Their long life cycle also contributes to lower environmental impact through reduced maintenance and redecoration.
Do Keim paints offer fire resistance?
Yes, Keim Mineral Paints are completely incombustible. They do not contribute to the spread of fire or emit harmful fumes when exposed to high temperatures, making them suitable for public buildings, heritage sites, and applications where fire safety compliance is a priority.
