Gypsum Plastering has faster setting time than cement plastering. The gypsum walls are paint ready in 4 days compared to 15 days with cement sand plastering. Sand cement plastering needs at least 15 days to reach the inherent properties, whereas gypsum gains its inherent properties within 48 days of application. Gypsum plasters gain their total strength within 78 hours.
Because Cement plastering consumes relatively higher time than gypsum plastering, it also demands more manpower than gypsum plastering. Gypsum plasters reduce the cost of electricity and the cost of putty, to bring about a savings in the overall construction cost by about 20% than cement plastering. Save up to Rs. 35 per sq. feet.
The leading engineers and architects in the world are working towards reducing the deadweight of high rise building to make them earthquake and wind proof. Gypsum has low density and higher compressive strength that results in lowering the weight and same time achieving the strength needed to load bearing sections of the building. Gypsum plays a vital role in enabling this, invariably all high rise buildings around the world use gypsum plastering to achieve this purpose.
Sand cement plastering requires 7 days of water curing while it is not the case with gypsum plastering. If the wall plastered with cement is not sprayed with water, it may dry soon resulting in cracks. Gypsum plastering does not require water curing and so lowers water consumption.
Gypsum plastering produces a smooth finish with perfectly leveled corners while sand cement plastering results in cracks. Due to this, cement plastering requires putty but gypsum plastered walls are paint-ready and does not require putty application. Cement plastered walls may also require a whitewash to cover cracks.
Cement industry is the source of 8% of global greenhouse gas emissions as it consumes more fuel to produce the thermal energy required for cement production. Gypsum is a naturally deposited mineral. Gypsum plastering the wall would help you increase the LEED certification points of buildings.
