Lightweight Gypsum Plaster | Low Density Wall Rendering Material for Smooth Interior Finishes

Q1 lightweight plaster gypsum is high-performance interior plaster based on premium β building gypsum, compounded with lightweight aggregates and polymer additives. It serves as an ideal replacement for traditional cement mortar, applicable for one-coat thick plastering on concrete, AAC blocks, brick and gypsum block interior walls, featuring low bulk density, high strength and crack-free thick-layer construction.

Lightweight One-Time Thick Plaster to Reduce Wall Load


Q1 adopts lightweight aggregate formula to cut wall dead load compared with heavy cement mortar. It realizes one-step thick plastering from 5 to 20mm without layered cracking, saving multi-pass construction steps for concrete and aerated block interior walls. Strong interlayer adhesion eliminates hollowing and shedding common in traditional cement plaster, delivering stable long-term wall substrate.


Smooth Construction & Stable Workability


Excellent water retention avoids slurry segregation and premature drying during large-area manual or mechanical spraying. Silky troweling texture reduces construction resistance for workers, compatible with both hand trowel and plaster spraying machine. Mixed slurry keeps stable working performance within 1 hour, easy leveling with aluminum straightedge for ultra-flat wall base before putty coating.


Green Indoor Plaster for Residential & Commercial Renovation


Pure gypsum-based eco material without toxic volatile components, naturally adjusts indoor humidity for healthier interior space. Simple standardized operation: clean & prime smooth concrete substrates → fixed proportion mechanical mixing → uniform thick plaster application → natural ventilation curing for 3–7 days. Factory pre-blended uniform powder ensures stable batch quality for mass residential, hotel and office interior plaster projects..
