About KEIM

Keimfarben GmbH, headquartered in Diedorf near Augsburg, is a manufacturer of silicate paints (mineral paints) and belongs to the corporate group of Leonhard Moll AG. The company was founded in 1878, when Adolf Wilhelm Keim patented his mineral paints; the invention emerged from research into water glass under King Ludwig I of Bavaria. The durability of the paint is based on the chemical bonding of the potassium silicate binder with the substrate (silicification). The product range includes exterior and interior mineral paints, renders and stucco, stone restoration, wood glazes, lime paints and concrete coatings. In addition to paint production, the company offers technical consulting and specialist planning for architects and applicators as well as services for historical heritage conservation. Buildings such as the White House, Buckingham Palace, the Sydney Opera House, the Bolshoi Theatre, the Kremlin and the town hall of Schwyz are painted with Keim paints.
