Water retentivity -> 95 %

How To Apply:

  • Clean any dirt, loose particles or grease from AAC blocks, fly ash or hollow blocks and pre-wet the areas before application.
  • Add Block Jointing Mortar to recommended 23% water and mix well for 5-10 minutes.
  • Apply using a mason’s notch trowel and make an even 3-4mm joint layer on a clean, dry block surface.
  • Correction time for re-alignment is up to 10 minutes to ensure perfection of block placement.
  • The Block Jointing Mortar is self-curing and does not require a water curing process, post-application.
