gräfix 66 K
Lime plaster finish
CS I · without added cement
A vapour-permeable lime finish containing crushed limestone sand, free from cement and synthetic or synthetic resin components. Thanks to its sorption properties, gräfix 66 K can absorb and release moisture, thereby helping to regulate moisture levels on the wall surface.
This lime finishing plaster is suitable for smoothing finely ground lime base coats.
When used outdoors, gräfix 66 K must always be protected against the elements.
Not suitable for use in the plinth area.

Air lime plasters in building biology
Air-lime plasters are used in both new-build and renovation projects for residential buildings. Mineral air-lime plasters combine various properties relevant to building biology and building physics.
Thanks to their open-pored structure and sorption properties, air lime plasters can absorb and release moisture. This enables them to help regulate moisture levels on the wall surface.
The high pH value creates conditions on the surface that can inhibit the growth of mould. Their vapour-permeable properties allow them to be used in appropriately constructed 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.
