Consumption
| Notched Trowel Size | Approx coverage per bag |
| 6mm Notched trowel | 11m2 |
| 10mm Notched trowel | 6m2 |
Consumption is always dependant on the substrate surface profile and roughness, and application technique.
MIXING
Pour the clean cool water into a mixing container and gradually pour the Prohesive Lite powder into the container and stir with a slow speed mixing drill (approx 500 RPM). Mix for 2-3 minutes to a smooth lump free homogeneous mix. Allow the adhesive to stand (slake) for 5 minutes then restir for an addition minute. Restirring the adhesive may be required during its pot life, do not add any additional water.
APPLICATION
Tiles shall be fixed in accordance with AS 3958.1-2007.
- Ensure the backs of tiles are clean and free from dust and contaminates.
- Apply the adhesive to the substrate with the appropriately sized notched trowel to achieve coverage requirement on both substrate and the back of the tile. Tiles may require back-buttering to achieve minimum coverage requirements.
- Apply the adhesive with a notched trowel in a single direction. Apply the tile, while pressing into the wet adhesive, break the adhesive ridges with the tile to fully bed the tile into the adhesive.
- It is advisable to periodically check the backs of the tiles for adhesive coverage requirements as the AS3958.1-2007.
- Only apply as must adhesive that can be covered prior to adhesive skinning. If skinning occurs remove and replace with fresh adhesive.
- Remove any excess adhesive from the face of the tile with a damp sponge and ensure grout joint are of uniform depth.
- Movement, expansion and control joints must be installed as per AS 3958.1-2007.
- For tile over tile applications, existing tiling must be adequately cleaned prior to application. Ensure existing tiling is sound and free from defects. Prime existing tiles with Sika Prep n Prime and allow to dry.
CLEANING OF EQUIPMENT
Tools and equipment can be cleaned while adhesive is still wet.
