The Definitive Guide
Why Gypsum Plaster?
Faster, cheaper and smoother than cement. Here's everything you need to know.
The Short Answer
For most homes and buildings, gypsum is the better choice
Cement plaster has been the default for decades. But builders and homeowners who switch to gypsum consistently report three things: the job finishes faster, it costs less in total, and the walls look better.
Gypsum gives a smooth, paint-ready surface without a putty coat. It sets in hours, not weeks. And it uses zero water for curing.
The one exception: bathrooms and external walls. Use cement there. For everything else — internal rooms, ceilings, corridors — gypsum wins every time.

The Benefits
Why gypsum outperforms cement plaster
Sets in Hours, Not Weeks
Gypsum sets within hours of application — paint-ready in 5 days. Cement takes 21 days of curing, slowing your entire project.
Skip the Putty Coat
A well-applied gypsum plaster gives a surface smooth enough to paint directly. Putty becomes optional — saving ₹8–12 per sq.ft of wall.
Zero Water Curing
Cement plaster needs 30 litres of water per sq.ft per day for 21 days. Gypsum needs none. Massive cost and resource saving on large projects.
35% Lighter Walls
Gypsum weighs 6–8 kg per sq.ft vs 11–13 kg for cement. Lighter walls reduce structural load — important for multi-storey buildings.
Better Fire Resistance
Gypsum contains crystalline water that releases when heated, slowing fire spread. It performs significantly better than cement in fire tests.
Better Thermal Comfort
Lower thermal conductivity than cement — your home stays cooler in summer and warmer in winter. Lower electricity bills over time.
