gräfix 61
Lime base coat
CS I · pure air-lime plaster without added cement
A base plaster that acts as a vapour-permeable interior plaster, ensuring an optimal indoor climate thanks to its extensive moisture exchange. It absorbs nitrogen oxides and volatile organic compounds (VOCs) through the ‘Clean Air’ effect. When used as an external plaster, gräfix 61 must always be provided with a weather-resistant finish.

Air-lime plasters are indispensable in building biology
No other wall coating offers comparable properties in terms of building biology and physical characteristics to mineral air lime plaster, nor does it create such a pleasant, healthy indoor climate by absorbing nitrogen oxides and volatile organic compounds (VOCs) and regulating humidity levels in the room.
This is why lime plaster is becoming increasingly important today in both new-build and renovation projects for residential properties. Particularly when there are children in the household, the topic of ‘healthy living’ is becoming ever more central. In terms of health and environmental sustainability, purely mineral air-set lime plaster is the ideal building material. Owing to its natural composition, it is of enormous value in terms of building biology and building physics.
Our air lime plasters have long been thoroughly tested by one of the leading institutes in the field of building biology. The intensive laboratory work, lengthy tests and the results of decades of experience have paid off.
An expert report covering every detail confirms the purely natural functioning of our gräfix lime range and stands as proof of its quality and well-deserved trust.
