Keim mineral paints are water borne, odourless, non-toxic and virtually VOC free, manufactured with natural ingredients using a low energy manufacturing process. Keim Mineral Paints contain neither solvents nor any petro-chemical derivatives, are inherently non-combustible and do not give off any toxic gases. Over their entire life cycle from raw material extraction to production, processing and ultimate disposal, mineral paints have an excellent environmental profile.

Mineral paint systems are based upon penetration (silicification) of the binder into the substrate. A strong, permanent bond is created between the paint and the underlying substrate (e.g. render, natural stone, concrete). This potassium silicate binder is highly resistant to weathering, ensuring an extremely long-life protective finish, reducing the frequency of re-decoration cycles. Keim mineral paints do not flake and the binder does not disintegrate under the effect of UV light. They are resistant to acid rain and industrial pollution.

Keim mineral paints have no residual electrostatic charge, unlike oil based paints, and therefore do not attract dust. Over time they remain cleaner than oil based paints. The silicate structure is highly stable and able to resist acid and alkali attack while the inherent alkaline nature of Keim mineral paints delays the growth of fungi and algae spores.

Keim paints are inherently resistant to mould and fungal growth due to their high alkalinity (pH is approximately 12.3), and will provide longterm resistance to mould and fungal growth. Keim paints are mineral based so there is nothing for algae to feed upon therefore preventing its growth and build up on surfaces.

Keim mineral paints contain exclusively high-quality, lightfast, mineral pigments and binders which exhibit the greatest UV resistance of all paint systems, and are absolutely weather-resistant. All Keim colours are unaffected by the action of weathering and UV radiation, ensuring no colour fade with the passage of time. Having a bright matt appearance, the crystal structure of Keim mineral paints gives a high level of light reflectance compared to oil based film forming paints of a similar colour.

Keim mineral paints are inherently non combustible, do not support the spread of flame and give off no noxious emissions due to their inorganic composition. Mineral paints are therefore ideal for use in safety critical public areas such as underground stations and tunnels, airports, schools and flats.

The micro-crystalline nature of the Keim coating system creates finite spaces between adjacent crystals, these voids are large enough to allow the free passage of vapour but small enough to prevent the ingress of driven rain. This imparts the Keim mineral paint system with high water vapour permeability. This high breathability enables humidity contained in building structures to be quickly released unhindered into the environment, avoiding moisture build up between coating and substrate. harmony with the environment.

Which Keim Paint System To Use

Keim External Paint Systems

Keim Granital – a classic mineral, matt finish silicate based paint for use on all forms of mineral substrates.

Keim Royalan - a mineral silicate based paint system developed to withstand harsh climatic conditions, ideally suited for use in exposed locations and those subject to continual pollutants and contaminants.

Keim Soldalit - a highly developed multi purpose exterior sol silicate paint system based on a combination of silica sol and potassium silicate binding agents, universally applicable for application on to organic, mineral and mixed substrates, combining the benefits of a classic mineral paint with simplicity of application.

Keim Concretal - effective protection for concrete while retaining its mineral character, The Keim Concretal system comprises mineral based concrete repair, decoration and protection materials, significantly reduces the rate of carbonation of concrete, providing a longlife decorative system for mineral protection.

Keim Concretal Lasur – a water repellent low pigmentation silicate colour wash, for protection against weathering and chlorides, which acts as a stain that penetrates the surface of concrete, equalising colour variations, whilst maintaining the structure and appearance of concrete.

Keim Lotexan – a clear dust suppressant and water repellent siloxane based treatment for use on alkaline mineral substrates such as concrete and new cementitious renders

Internal Keim Paint Systems

Keim Ecosil ME - a high performance, environmentally friendly mineral paint for interior use. Internal silicate paint which optimises air quality, using photo-catalytic pigments to reduce noxious gases and odours by transforming them into natural substances.

Keim Innostar - Bright white one coat interior paint. Perfect for ceilings and interior walls.

Keim Optil - a premium quality sol-silicate paint specifically formulated for elegant interior applications, giving intense, lightfast colour shades.

Renders and Repair Materials

Keim Universal Render - a ready to use renovation and thin layer wall render, based on hydraulic lime and white cement with sand and mineral fibre fillers, for use on all mineral substrates, both interior and exterior.

Keim Restauro Stone Repair System - a systematic system for restoration of natural stone: cleaning, consolidating, reinstating, water repellent impregnation, and coating.

Keim Restauro Lasur - a classic low pigment coating for natural stone, using a sol/silicate-based binder formulation, suitable for providing optimum protection for natural stone.
