MIXING

  1. Measure the required amount of clean potable water into a bucket (6-7 Litres per bag). 
  2. Slowly add the powder into the water while mixing with a mixing paddle attached to a drill (Max 500 RPM). Do not mix by hand.
  3. Continue to mix for 2-3 minutes until a smooth, limp free creamy mixture is achieved. 
  4. Allow the mixture to stand for 5 minutes then restir for an additional minute.

*Adhesive may need re-stirring during the potlife, do not add more water.

APPLICATION

Laying the Tiles

  1. Place the adhesive onto the prepared and primed substrate. Do not apply more adhesive than can be tiles within the open time of the product, usually from a single tile to 1m2.
  2. Hold the notched trowel at an angle of 60° or greater to the substrate.
  3. Spread the adhesive over the required area where tile is to be applied, comb the adhesive in a single direction (not swirls).
  4. Where "back buttering" the tile is required, use the flat side of the notched trowel to apply a thin adhesive layer to the back of the tile (approx 1-2mm thick).
  5. Place the tile into the combed adhesive and press the tile firmly.
  6. Move the tile forward and then back at 90° across the direction of the combed adhesive to flatten the adhesive to leave no voids under the tile. Occasionally life a tile to check the adhesive covers 90-100% of the tile.
  7. Remove any excess adhesive in the joints, and on the face of the tile with a sponge and water while the adhesive is still wet.
  • Do not allow the adhesive to skin prior to placement of the tiles. If the adhesive skins, remove and replace.
  • Application shall be in accordance with AS3958.1
  • Movement joints shall be installed in accordance with applicable standards.
  • Back buttering the tiles may be required to achieve minimum coverage requirements.
  • Allow the adhesive to dry prior to grouting.

CLEANING OF TOOLS

Tools & equipment can be cleaned with water prior to the adhesive drying.
