Directions for Use
Pre-Treatment of Substrate
Ensure the substrate is clean, sound, and free of oil, grease, dust, or loose material.
Remove surface contaminants by water-jet washing or blast cleaning.
Pre-dampen absorbent surfaces before application (Saturated Surface Dry – SSD condition).
Avoid standing water or wet/dark-matt surfaces.
Bonding Agent
For large areas or dense concrete substrates, use a bonding agent such as IZOZENĀ® IZOBOND EP to enhance adhesion.
Mixing Instructions
Mix one 25 kg bag with the recommended quantity of cold water.
Use a slow-speed electric mixer (max 500 rpm) with a spiral paddle.
Add powder gradually while mixing for at least 3 minutes until a uniform consistency is achieved.
Do not use aluminum paddles.
Do not add extra water or other materials.
For best results, mix full bags only.
Mixing Ratios:
Dry Pack / Trowelable: 0.09 W/P Ratio
Plastic Consistency: 0.10 W/P Ratio
Flowable: 0.11 W/P Ratio
Highly Flowable: 0.12 W/P Ratio
Application
Allow the mixed grout to stand for 5 minutes before use to release air bubbles.
Pour into the prepared area, ensuring the shortest flow distance.
Displaced air must escape freely.
When base plate grouting, maintain sufficient head pressure for continuous flow.
Minimize exposed surface areas to reduce shrinkage.
Layer Thickness:
Minimum: 10 mm per pour
Maximum: 50 mm per pour
