• High diffusion resistance against CO2 reducing the rate of carbonation
• Water vapour permeable
• Very good resistance against weathering and ageing
• Environmentally friendly (solvent free)
• Reduced tendency to dirt pick up and contamination
• The system is resistant to aggressive atmospheric influences
