gräfix 73 Pajalith
Ultra-light, mineral base render for direct plastering of straw elements
CS I
The ultra-lightweight finishing render for straw substrates with optimised adhesion and application properties is fibre-reinforced, particularly breathable and characterised by a low modulus of elasticity.
gräfix 73 Pajalith is specially designed for use on straw as a plaster base. Thanks to its special, customised formulation, it can be used wherever straw is used as a wall construction material, e.g. in the form of construction straw bales.

Build more naturally - live healthier
With straw and gräfix 73 Pajalith
Straw bale houses, the ultimate in organic building and living culture. The oldest construction method, modern and more up-to-date than ever thanks to the building-biological passive house quality and energy efficiency.
Highly compressed straw bales are used between timber constructions. The straw bales are plastered directly with gräfix 73 Pajalith, which gives the entire wall construction flame-retardant fire protection. A wall construction based on a renewable raw material with excellent and natural thermal insulation and functional fire protection - an absolutely healthy construction method in terms of building biology and building physics.
