GYPSUM PLASTERING BENEFITS
Ease of Application (Workability)
Gypsum can be directly applied over brick/cement block/Laterite/ interlock, work without separate finishing. It is also very easy to level and apply gypsum plaster.
No Shrinkage Cracks
Gypsum reaction produces less heat as compared to cement reaction with water. So there are no Shrinkage cracks in gypsum plaster as compared to traditional cement plaster
Quick Setting Time
Gypsum sets quickly (i.e., within 25-30 min). So painting could be started 72 hours after application of gypsum plaster. Plaster has to be dried up before painting.
No curing required
Unlike Traditional Cement Plaster, Gypsum plaster doesn’t need any curing saving water and time during construction
High Productivity
Reduces time considerably when compared to conventional cement plaster
High Performance
Excellent high strength after drying and Durable for LifeTime
Smooth Finish
Perfectly lined, levelled, smooth walls and perfect right angled corners
Reduced Supervision
Careful quality checking is required for cement plaster as cement and sand has to be properly proportioned. In contrast, gypsum plaster doesn’t require same amount of quality checks for application thus reducing supervision efforts.
Fire resistant
Gypsum plaster is highly resistant to fire
Low thermal conductivity
Gypsum has low thermal conductivity. This saves electrical cost for heating and cooling rooms in a building.
Sound Proof
Gypsum by nature is sound absorbent. Makes this suitable for schools, thin wall apartments and multiplex to prevent sound to travel outside rooms
Cement Vs Gypsum – Comparison
| Cement | Gypsum |
|---|---|
| Risks involved as sand and cement is to be mixed and processed at the site. | The plaster is a ready mix of gypsum. Hence saves effort and time in a big scale. |
| Sand is used as an aggregate. | As Exfoliated Vermiculite is the aggregate, it reduces heat. [good thermal insulator]. |
| Rough finish and water patch marks occur. | Smooth fine finish with no water patch marks. |
| Requires POP punning for surface finish after sand-cement plaster. | Smooth finish is obtained in single application itself. |
| Setting time : 60 – 160 mins | Setting time : 20 mins |
| Water cracks or shrinkage cracks may happen. | Provides crack free smooth surface, once set. |
| High labour cost and consumes time. | Time saving, hence less labour cost comparatively. |
| Structural changes can happen according to heat variation. | Gypsum is Heat resistant so no damage occurs. |
| Cemented Surface will crack apart and burst when hit by a hard object. | Gypsum Plaster will only form a dent when hit by a hard object and will be safe. |
| “Re work, fittings, refinishing” all are quite difficult in cement walls. | Gypsum walls are easily maintainable. |
| Cement surfaces are catalysts to fire. | Gypsum protects your walls from direct fire. |
| More electricity usage as AC is used inside cement walls. | Due to low thermal conductivity of gypsum, AC usage will be less and hence low electricity bills. |
| Direct Application | Line & Level | Smooth Finish | Time Saving | Quality Assurance | Water Curing | Shrinkage Cracks | |
