Application Instructions
- Surface Preparation:
- Clean the area thoroughly to remove dust, oil, grease, or loose concrete.
- Pre-wet the substrate before placing, ensuring no standing water.
- Mixing:
- Add 3.5–4.0 L of water per 25 Kg bag and mix for 3–5 minutes until a smooth, uniform consistency is achieved.
- Application:
- Place the mix immediately after preparation.
- Compact properly to remove trapped air.
- Finish with a trowel for smooth surfaces if required.
- Note: Begin curing immediately after initial set using wet burlap or curing compound.
Coverage Calculator
- 1 bag (25 Kg) yields approximately 12–13 liters of mixed concrete.
- Coverage varies with thickness and repair depth.
Suitable Applications
- Structural concrete patch repairs
- Grouting under base plates and machinery
- Anchoring bolts, dowels, and rails
- Repair of bridge decks, columns, and slabs
- Areas requiring quick return to service
Compatibility & Limitations
- Compatible with concrete, steel, and masonry substrates.
- Avoid application in direct sunlight or temperatures above 35°C.
- Do not re-temper or add extra water after initial mixing.
Safety & Handling
- Wear gloves, goggles, and protective clothing during mixing and placement.
- Avoid inhalation of dust and contact with eyes or skin.
