LK-Aqua EM 290Q
Water repellent additive for cement
Introducing LK-Aqua EM 290Q: Advanced Water-Repellent Cement Additive
LK-Aqua EM 290Q is an innovative silane based additive designed to significantly enhance the durability and longevity of cement by imparting superior water-repellent properties without interfering with the hydration process.This is a next-generation solution for achieving long-lasting (durable in humid environment), high-quality cement structures with built-in water repellency. Perfect for infrastructure, residential, and industrial applications, this additive ensures superior performance without compromising the integrity of your cement formulations.
Key Features & Benefits:
- Superior Water Repellency: Forms a hydrophobic barrier to reduce water absorption and ensures deep penetration for enhanced performance.
- Enhanced Durability: Reduces water absorption to prevent spalling from freeze-thaw cycles and increases resistance to cracking in extreme weather conditions. Also extends the shelf life of cement bags in humid conditions.
- Efflorescence Resistance: Prevents white salt deposits by controlling water movement within the cement.
- Eco-Friendly & Easy to Use: Solvent-free, aqueous-based, environmentally friendly, and requires a low dosage with fast water-beading action.
- Maintains Breathability & Aesthetic Appeal: Allows vapor transmission while repelling liquid water and preserves the original look of the cement surface.
Technical details:

Usage Instructions:
- Dosage: To be optimized based on cement type and application requirements. For OPC cement worked well dosage ~ 0.06- 0.08%
- Application Method: Add directly during clinker grinding for best integration.
Applications:
LK-Aqua EM 290Q is added during the clinker grinding stage to ensure uniform dispersion and long-term performance. This treated cement is suitable for:
- Waterproof plaster & mortar
- High-performance concrete in humid climates
- Precast concrete for long-term durability
- Bridge decks, tunnels, and marine structure
