gräfix 61 Hair
Hair-lime base coat
CS I · without added cement
Pure air-lime base plaster with crushed limestone sand and animal hair. A vapour-permeable interior base plaster with excellent sorption properties. Thanks to its ability to absorb and release moisture, gräfix 61 Haar helps to regulate moisture levels on the wall surface.
When used as an external plaster, gräfix 61 Haar must always be provided with a weather-protective coating.

gräfix Lime Range Excellent
Mineral coatings such as air lime plaster: a mainstay of building biology
Lime plaster is used in both new-build and renovation projects for residential properties. Purely mineral air lime plaster combines various properties relevant to building biology and building physics.
Thanks to its high open porosity and sorption properties, air lime plaster can absorb and release moisture. This enables it to help regulate moisture levels on the wall surface.
Due to its high pH value, conditions are created on the surface that can inhibit the growth of mould. gräfix air lime plasters are free from synthetic solvents and are suitable for vapour-permeable mineral wall systems.
Trust through transparency
The gräfix lime range is based on a purely mineral formulation. The air lime plasters were tested in 2017 by the Institute for Building Biology and Sustainability (IBN) in Neubeuern.
