Breathable Facades
A building’s façade is its first line of defence and a key element for sustainable construction. In this regard, KEIM’s exterior mineral paints meet the highest quality standards: they are durable, colour-stable, eco-friendly, and cost-effective.
Coating a façade with a silicate exterior paint provides protection against rain and heat, withstands storms, and influences the building’s interior climate. Unlike conventional paints, mineral paint does not form a surface film but instead reacts with the substrate, becoming one with it. This ensures that the paint does not crack or peel over time.
Moreover, KEIM’s mineral paints for façades are highly vapour-permeable. This means that moisture can freely pass in and out, allowing damp façades to dry quickly. As a result, moisture cannot accumulate between the paint and the substrate. The quick-drying properties, combined with the other characteristics of KEIM’s silicate paints, mean that the façade offers no nutrients for fungi and algae, providing natural protection against microorganisms.
Within the range of exterior mineral paints, KEIM Soldalit is a universal sol-silicate paint solution that is easy to apply, dries evenly, and offers excellent coverage. This is due to KEIM’s unique combination of silica sol and potassium silicate, which creates a binder that not only performs exceptionally well on mineral substrates but also demonstrates outstanding adhesion on old resin-bound paints and renders. Its unique composition ensures that it is completely UV-resistant and that its colour remains unchanged over time.
Mineral paints are also antistatic and non-thermoplastic, making it much more difficult for dirt to adhere to the surface. This property is particularly significant in KEIM Soldalit-ME, a photocatalytic sol-silicate paint that protects the façade and cleans the air by contributing to the reduction of nitrogen dioxide. The photocatalytic effect also breaks down algae and organic dirt, keeping the surface cleaner. Its additional cost compared to conventional paint is minimal, offering significant added benefits for both people and the environment. With Soldalit-ME, façades maintain a noble mineral appearance, remain protected for many years with stable colour, and are both sustainable and capable of improving air quality.
In warmer climates, especially on External Thermal Insulation Composite Systems (ETICS), solar heat can be a problem for façades. KEIM Soldalit-Coolit is the ideal solution, being an innovative sol-silicate paint designed to reduce solar overheating in intense colours. This paint incorporates heat-reflective pigmentation, which means façades absorb significantly less solar radiation, making it possible to use vibrant colours even on thermal insulation systems.
KEIM’s silicate mineral paints demonstrate an outstanding ecological profile, from raw material extraction to disposal, and have been awarded Cradle to Cradle® Silver certification for 80 products. These are recyclable, circular, and healthy mineral paints, with the C2C Certified Material Health Certificate™ at Gold Level. Absolutely safe paints for sustainable architecture and healthy living spaces. All this with a matte mineral finish that stands out for its aesthetic appeal and beauty, offering durable, clean façades with long-lasting colour stability.
