Application

Application steps

APPLICATION

  • Always use clean, dry tools and add approximately 3-parts powder to 1-part clean, cold water by volume.
  • Mix quickly to form a smooth paste.
  • IMPORTANT: Do not mix more cement than can be used within 5–10 minutes.
  • Apply the mixture immediately with a trowel or filling knife, working it well into the area.
  • Level with the surrounding surface, as the mixture will begin to set within 10 minutes.
  • Once the product begins to stiffen, do not use any remaining residue or add further water to the mix, as this will reduce its strength.
  • In warm conditions, cover with polythene to assist curing.  

CLEANING OF TOOLS

Clean all tools immediately with warm water before the repair mortar dries.
