Surface Preparation
  • 1. Check that all tiles/stones are securely fixed and that the adhesive has thoroughly set.
  • 2. It is essential that the tiles/stones are fixed in the correct manner i.e. in a solid bed of adhesive without any voids beneath the tiles/stones.
  • 3. Ensure the joints are dry and free from dirt and other loose materials.
Application Method
  • 1. Add 5 parts of grout to 1 part of water and mix by hand or slow speed mixer (>300 rpm) until a lump-free, smooth, workable and stiff paste is obtained.
  • 2. Using a grout float or rubber squeegee compact JOINTFILL 12 into the joints ensuring that they are completely filled.
  • 3. Work in small areas and remove as much excess grout as possible from the tile surface.
  • 4. Once the grout has sufficiently set within the joints, polish the tile surface with a clean cloth. Alternatively give a final wash down with clean water using a dampened sponge.
