Cement Render & Plaster Additives – LANDU
Standard cement-sand mixes often suffer from cracking, sagging or inconsistent workability on site. For dry mix mortar manufacturers and contractors, reliable cement render and plaster additives are essential for stable application performance across different climates and substrates.
LANDU supplies cellulose ethers and redispersible polymer powders designed for cement render and plaster formulations. Our additive solutions help improve water retention, open time, adhesion and workability while maintaining stable mortar consistency at lower dosage levels.
Benefits of Cement Render & Plaster Additives:
Improved adhesion to various substrates
Increased water repellency and hydrophobicity
Improved water retention, consistency and stability
Reduced primary and secondary efflorescence
LANDU: Your Trusted Cement Render Manufacturer
Landu products are used to improve the workability, adhesion, flexibility and surfaceresistance of such renders. Additional properties like hydrophobicity, thixotropicity aswell as reduced efflorescence can also be achieved by the use of our specialty additives.

Recommended Additives for Cement Render & Plaster
LANDU supplies a complete range of dry mix mortar additives for cement render and plaster applications.
HPMC is one of the most widely used cement render additives in dry mix mortar formulations.
- Improved water retention
- Better workability
- Enhanced anti-sag performance
- Longer open time
- Smoother application consistency
LANDU HPMC grades are suitable for both hand-applied and machine-applied plaster systems.
Redispersible polymer powder (RDP) plays an important role in improving flexibility and adhesion in cement plaster systems.
- Improved bonding strength
- Better crack resistance
- Enhanced flexibility
- Improved impact resistance
- Reduced dusting and surface brittleness
RDP is commonly used in exterior render, repair mortar and high-performance plaster applications.
HEMC additives provide stable viscosity and reliable construction performance in cement plaster formulations.
- Easy mixing and application
- Improved troweling performance
- Stable thickening effect
- Better moisture retention
- Consistent mortar quality
HEMC is particularly suitable for projects requiring stable workability under different environmental conditions.
Common Challenges in Cement Render & Plaster Formulations
During mixing, application and curing, cement renders and plasters can suffer from poor water retention, cracking or sagging. The right additives prevent these problems.
Poor Water Retention
LANDU cellulose ether additives help maintain moisture inside the mortar system, allowing for better cement hydration and improved plaster performance.
Sagging During Vertical Application
Our HPMC and HPS additives improve consistency and sag resistance, making render mortar easier to apply on walls and ceilings.
Cracking After Drying
LANDU RDP solutions improve flexibility, adhesion and crack resistance in cement render applications.
