In the field of interior wall plastering, traditional cement mortar is gradually giving way to a more efficient, eco-friendly alternative: lightweight plastering gypsum. As an air-hardening material based on building gypsum, blended with optimized additives and aggregates, it not only addresses the long-standing drawbacks of traditional plastering but also marks a significant leap forward in construction efficiency and wall performance.
Plastering gypsum boasts exceptional bonding to various substrates—especially aerated concrete walls—eliminating the need for additional primers. Its micro-expansion properties effectively counteract shrinkage, preventing hollowing, cracking, and spalling, thus significantly reducing post-construction repair costs.
The hardened surface is dense, dust-free, non-toxic, and odorless. What’s more, its microporous structure enables "breathability," automatically regulating indoor humidity to boost living comfort. Additionally, gypsum offers excellent flame retardancy: when exposed to fire, it releases crystallized water to form a protective barrier, greatly enhancing building safety.
Thermal insulation: With a thermal conductivity only 30% that of concrete, it cuts down on energy consumption.
Rapid hardening: Achieves required strength in just 1–2 days—70% faster than cement mortar—making it ideal for time-sensitive projects.
Winter compatibility: Maintains stable hydration even in low temperatures, allowing construction as long as mixing water remains unfrozen, breaking free from seasonal constraints.
Ease of operation: Simply add water, mix on-site, and apply directly to walls—no complex processes, reducing labor intensity.
Material efficiency: Its lightweight nature lowers transportation and handling costs. A single layer can reach over 10mm in thickness, eliminating the need for multiple coats.
High-quality finish: The wall surface is highly level, ready for direct painting or decorative layers without additional leveling work.
