KEIM Concretal®Lasur is a low pigmentation silicate colour wash, which acts as a stain that penetrates the surface of concrete, equalising colour variations and blemishes.


KEIM Concretal Lasur maintains the structure and appearance of concrete and enables specifiers and contractors to achieve concrete surfaces of a consistent quality appearance.

KEIM Concretal Lasur equalises unacceptable variations in colour and texture of concrete, hides unsightly repairs, reduces surface dusting and increases light reflectivity.  

KEIM Concretal Lasur is available in a wide range of colours and degrees of opacity, and is tailored to individual requirements.
