The beauty of concrete

Concrete cosmetics with mineral colours made by KEIM

Silicate paints on concrete

Silicate paint materials do not form a film on the concrete surface like synthetic resin based coatings.
The binding agent is a water-soluble potassium water glass which forms an insoluble bond with the substrate by a chemical reaction, the so-called silicification

KEIM concrete glazes refine the look of concrete.


Fair-faced concrete – one of the biggest challenges and at the same time an important element in architecture. Contrary to highly synthetic-modified systems the mineral glaze highlights the natural character of concrete in a unique way and provides an additional weathering protection. KEIM Concretal-Lasur offers unlimited design possibilities – from highly transparent to opaque – and is definitely much more flexible and economical than tinting concrete!

Mineral nature of the concrete look

Matt, silicate coatings look much more natural than synthetic coatings. Dispersions lead to dry layer thickness between 0.3 mm and 0.5 mm thus levelling irregularities and cover the material texture of the concrete. Appearance and haptics are distorted, violating the natural beauty of the concrete.

KEIM concrete coatings retain and design concrete surfaces

Mineral coatings don‘t overlay the natural concrete texture, in fact they accentuate. This is especially the case when the application is performed in glazing technique with semi-transparent up to highly translucent coatings. Mineral paints, stains and glazes retain the aesthetic of the material even with a colour design and provide clearly more flexibility than tinted concrete.

"Concrete has a rough quality which I like. Architecture should have a vital, earthy charisma and not look smooth and polished."
(Zaha Hadid - icon of contemporary architecture)

Concrete – a building material as versatile as life.


KEIM Concretal-Lasur-System consists of KEIM Concretal-Lasur, KEIM Concretal-Base and KEIM Concretal-Fixativ. All three system components can be mixed with each other in any desired ratio. This is a maximum of flexibility and enables a natural and visual colour matching of the concrete surface.


Sometimes concrete behaves like a diva and tends to have unexplainable streaks, discolouration or blowholes that affect the surface appearance substantially. At this point the concrete glaze comes into play, a mineral stain which, when diluted in various degrees, helps to conceal visual shortcomings so that the finish looks like original intented.

This special kind of cosmetics has already salvaged a number of famous buildings by reviving its concrete surface.
