Produced by our friends at Keim in Denmark this is a fantastic video showing the possibilities of Lasur. There are a few translation issues with the text, but it's worth a look and really shows the possibilites and effects which can be created with Lasurs. Keim Concretal Lasur is 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 Concretal Lasur equalises unacceptable variations in colour and texture of concrete, hides unsightly repairs, reduces surface dusting and increases light reflectivity.
