MIXING
Pour cool fresh water into a clean mixing container before slowly adding the adhesive powder. Mix with a slow speed drill (≈500rpm) for approximately 2-3 minutes to achieve a smooth lump free homogenous lump free mixture. Allow the mixture to Stand for 5 minutes, then re-stir for an additional 2 minutes without adding any additional water.
Restirring the mixture may be necessary during the potlife.
APPLICATION
Tiles shall be fixed in accordance with AS3958.1-2007.
Ensure the backs of the tiles are clean and free from dust and contaminates.
Apply the adhesive to the substrate with the appropriately sized trowel to achieve coverage requirement on both substrate and the back of the tile. Tiles may require "back-buttering" to achieve maximum coverage requirements.
Apply the adhesive with the notched trowel in a single direction. While pressing the Tile into the wet adhesive, break the ridges with the tile to fully bed the tile into the adhesive.
It is advisable to periodically check the back of the tiles to ensure adequate adhesive coverage is achieved in accordance with Australian Standards.
Only apply as much adhesive that can be covered by the tiles prior the adhesive skinning. If skinning occurs prior to placement of tiles remove and replace.
Remove any excess adhesive from the face of the tiles with a damp sponge and ensure grout joints are clean and free from excess adhesive and uniform depth.
Movement, Expansion, and Control joints must be installed as per AS ISO 3958.1-2007.
For tile over tile applications use Eco Systems Prep n Prime. Ensure existing tiles are soundly fixed and free from defect. Gloss finished or polished tiles need mechanical preparation prior to priming with Eco Systems Prep n Prime.
CLEANING OF EQUIPMENT
Tools and equipment can be cleaned with water prior to adhesive setting.
