- Drying time over membranes will be greatly extended.
Consumption
A 4 Litre pail will cover approximately 3m2 with a 6mm notch trowel.
A 15 Pail will cover approximately 11m2 with a 6mm notch trowel.
EQUIPMENT
Select a trowel with a suitable notch size for the tile size and type as per the following:
| Tile Size | Trowel notch size | Back buttering required |
| Mosaics | 4-6mm | No |
| 150x150 | 6mm | No |
| 200x200 300x300 400x400* 600x300* | 8mm 10mm 12mm 12mm | No No Yes Yes |
*Tiles larges than 200x200 size must have a porous base (greater than 3%).
APPLICATION
Laying the Tiles
- 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.
- Hold the notched trowel at an angle of 60° or greater to the substrate.
- Spread the adhesive over the required area where tile is to be applied, comb the adhesive in a single direction (not swirls).
- 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).
- Place the tile into the combed adhesive and press the tile firmly.
- 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.
- 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
Clean tools and equipment with water prior to adhesive drying.
