gräfix 61 organic
Lime base coat
CS I · pure air-lime plaster without added cement
A base plaster that is vapour-permeable and, thanks to its extensive moisture exchange, ensures a pleasant and balanced indoor climate. Thanks to its open-pored structure, it also has the natural ability to absorb and bind nitrogen oxides and volatile organic compounds (VOCs) from the indoor air. Thanks to its purely mineral, pollutant-free composition and the natural mould-inhibiting effect of air lime, this plaster is an excellent choice for sensitive living areas and is ideally suited to people with a keen awareness of healthy living.
When used as an exterior plaster, gräfix 61 bio must always be fitted with a weather-resistant protective coating.

Mineral coatings such as air lime plaster: a mainstay of building biology
Lime plaster is all the rage – which is why it continues to grow in importance today in both new-build and renovation projects for residential properties. Purely mineral air lime plaster offers clear advantages for healthy and environmentally conscious living: it is free from synthetic solvents, breathable and helps to ensure clean indoor air.
In terms of healthy living and environmental sustainability, purely mineral air lime plaster offers clear advantages in terms of building biology and building physics. Thanks to its high open-porosity, it regulates indoor humidity and naturally prevents mould growth, as it has a naturally high pH value and actively promotes a pollutant-free indoor climate.
Trust through transparency
The gräfix lime range is based on an unaltered, purely mineral formula. As early as 2017, the Institute for Building Biology and Sustainability (IBN) in Neubeuern certified the impeccable building biology quality of our air-limestone plasters in a comprehensive laboratory test. A solid foundation that builders have been able to rely on for years.
