Performance Drivers of Gypsum Plaster
- Direct Application: Single coat application directly on brick, block & concrete walls
- Crack Free: Free of shrinkage cracks
- No Curing: Requires no water curing
- Light Weight: Density being less, weight of finished product is much lighter
- High Productivity: Additives impart high coverage resulting in more work in less time and low wastage
- Time Saving: Results in substantial time saving as compared to conventional plastering methods
- Ready to use: Easy to apply imparting better cohesiveness and adhesion
- Fire Protection: They are non-combustible when tested in accordance with BS 476: Part 4: 1970
- Low Thermal conductivity: Gypsum’s inherent nature helps in energy conservation
- Thermal resistance: R = 0.07 m²K/W at 13mm thickness
