Lightweight Gypsum Plaster | Low Density Wall Rendering Material for Smooth Interior Finishes
Q1 Lightweight Plaster Gypsum is a high-performance interior plaster made from premium β building gypsum, lightweight aggregates and polymer additives. It is a suitable replacement for traditional cement mortar, designed for one-coat thick plastering on concrete, AAC blocks, brick and gypsum block interior walls, offering low bulk density, high strength and crack-free thick-layer application.
Q1 uses a lightweight aggregate formulation to reduce wall dead load compared with heavy cement mortar. It enables one-step thick plastering from 5 to 20 mm without layered cracking, helping to save multiple passes during application on concrete and aerated block interior walls. Strong interlayer adhesion prevents hollowing and flaking commonly seen with traditional cement plaster, providing a stable long-term wall substrate.
Excellent water retention helps prevent slurry segregation and premature drying during large-area manual or mechanical spraying. The fine troweling texture reduces application resistance, making it suitable for both hand troweling and plaster spraying machines. The mixed slurry maintains stable working performance for up to 1 hour, allowing easy leveling with an aluminum straightedge to achieve an ultra-flat wall base prior to putty coating.
Made from pure gypsum-based eco-friendly material with no toxic volatile components, it naturally helps balance indoor humidity for a healthier interior environment. Simple, standardized operation: prepare by cleaning and priming smooth concrete substrates → mix mechanically using a fixed proportion → apply thick plaster uniformly in one step → allow natural ventilation curing for 3–7 days. Factory pre-blended, uniformly graded powder supports consistent batch quality for large-scale residential, hotel, and office interior plastering projects.
