  • Can be used as a rapid drying, easy to apply alternative to traditional lime-based plasters.
  • Compatible with both modern and traditional substrates including masonry, block, stone and wooden lath.
  • Prevents corrosion of metal fixtures such as angle beads and lath.
  • Provides a barrier to salt and efflorescence.
  • Mould resistant.
  • 24-hour drying time.
  • Insulating - contributes to the U-value of buildings.
  • Fibres reduce cracking and crazing.
  • Reduces condensation.
