Self-Leveling Compound Additives | HPMC, RDP & HPS
Self-Leveling Mortar Additives for Better Flow & Strength
Common Challenges in Self-Leveling Compound Formulations
Self-leveling compounds require a precise balance of flowability, open time, leveling performance and crack resistance. Variations in raw materials, rapid cement hydration and poor rheology control can lead to common application issues such as pinholes, shrinkage cracking and uneven surfaces.
Benefits of Cement Render & Plaster Additives:
- Enhanced leveling performance, improved surface finish, and higher abrasion resistance
- Higher flexural strength and tensile bond strength across diverse substrates
- Simplified formulation processes and reduced complexity
- Greater flexibility to use raw materials of varying qualities
- Effective stabilisation against bleeding and segregation

What Is a Self-Leveling Compound?
A self-leveling compound is a cement-based flooring material designed to create smooth and flat surfaces before the installation of tile, vinyl, wood or other floor finishes. Self-leveling systems are widely used in residential, commercial and industrial flooring applications due to their fast application speed, high flowability and excellent surface leveling performance.

Key Additives for Self-Leveling Compounds
HPMC, PCE superplasticizers and redispersible polymer powders are widely used in cement-based self-leveling systems to improve application stability and overall flooring performance.
HPMC is commonly used in cement-based self-leveling formulations to improve water retention and application stability.
- Improves water retention and rheology control
- Extends open time and working stability
- Reduces bleeding and material segregation
- Supports smoother leveling performance
- Helps achieve more consistent surface quality
Polycarboxylate ether (PCE) superplasticizers are essential for achieving high flowability and smooth self-leveling performance with lower water demand.
- Increases flowability while reducing water usage
- Improves self-leveling and spreading performance
- Enhances surface flatness and workability
- Supports fast and efficient application
- Helps maintain stable formulation consistency
Redispersible polymer powder (RDP) improves flexibility, adhesion and long-term durability in self-leveling flooring systems.
- Improves flexibility and bonding strength
- Enhances crack resistance and durability
- Reduces shrinkage-related surface defects
- Improves resistance to surface wear
- Supports long-term flooring performance
Solving Common Problems in Self-Leveling Compounds
| Common Challenge | LANDU Additive Solution |
|---|---|
| Poor flowability and difficult spreading | PCE superplasticizers improve flow performance and surface leveling with lower water demand. |
| Bleeding and material segregation | LANDU cellulose ethers help stabilize the formulation and reduce segregation during application. |
| Shrinkage cracking after curing | RDP improves flexibility and helps reduce shrinkage-related cracking. |
| Short working time in hot conditions | Optimized HPMC grades support better water retention and extended open time. |
| Uneven surface finish | Combined additive systems improve leveling consistency and surface smoothness. |
Superior Flowability
LANDU PCE superplasticizer greatly optimizes mortar fluidity, enables easy spreading and perfect self-leveling effect with less water dosage.
