Gräfix 66 HP
Lime-based bonding render
CS I · based on white hydrated lime
A lime-based adhesive plaster containing crushed limestone sand and adhesion-enhancing additives produces a tension-free skim coat for preparing critical substrates for subsequent lime plasters. gräfix 66 HP is a vapour-permeable interior plaster which, thanks to its extensive moisture exchange, ensures an optimal indoor climate. Another key advantage is its natural ability to absorb nitrogen oxides and volatile organic compounds (VOCs). When used as an exterior plaster, gräfix 66 HP must always be protected against the elements.
Not suitable for use in the plinth area.

Mineral coatings such as air lime plaster: a mainstay of building biology
Lime plaster is very much in vogue – which is why it is becoming increasingly important 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 formulation. 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 property developers have been able to rely on for years.
