  • Colour intensity and uniformity.
  • Reduction of algae, fungi and mass growth on surfaces.
  • Reduction of dirt pick-up.
  • Faster drying process, which will increase the production rate.
  • Increasing the physical properties such as compressive, flexural and tensile strength.
  • Gives stronger colour shades which reflects in reduction of pigment levels.
  • Highly alkaline resistant.
  • During the manufacturing process, it will give better demoulding, and provide sharper edges.
  • Reduces chloride intrusion.
  • Breathable, allows for water vapour release.
