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:
LANDU CE, RDP and other additives products sup-port the rheology and workability of the full range of flooring formulations improving easeof on-site application and ensuring exceptionally smooth, defect-free surfaces.
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.

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.
Polycarboxylate ether (PCE) superplasticizers are essential for achieving high flowability and smooth self-leveling performance with lower water demand.
Redispersible polymer powder (RDP) improves flexibility, adhesion and long-term durability in self-leveling flooring systems.
| 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. |
LANDU PCE superplasticizer greatly optimizes mortar fluidity, enables easy spreading and perfect self-leveling effect with less water dosage.
Professional LANDU HPMC cellulose ether effectively suppresses bleeding and segregation, keeps formula stable during construction.
LANDU RDP powder enhances flexibility, reduces curing shrinkage and avoids surface cracks for long-term smooth finish.
