Frequently asked Questions

Our internal research study revealed that, for every sq.ft, gypsum plastering saves 30% more than cement plastering in terms of cost. Gypsum plastering consumes 75% time lower than cement plastering. Unlike Cement plasters, gypsum plasters do not require water curing and putty application. Overall, gypsum plasters have lower manpower and resource requirements and so are cost-effective.  

Gypsum plastering offers numerous benefits than cement plastering in terms of resource consumption, durability, output and acoustics. Gypsum Plastering is fire resistant, sound proof and heat resistant. Amazingly better properties than cement sand plaster.

We have a research team that continuously finds ways to achieve consistent and lifetime quality. Our quality process is constantly evolving and we are on path to have the highest quality standards in plastering. Our checklists for quality inspection are the best in the world for plastering. In short we Kanish Plasters are defining the gold standards of plastering in India.

Yes. Gypsum is a very forgiving surface. Any primer and paint can be used on gypsum. However primer needs to be applied before applying paint. All types of paints, wallpapers, and special texture paints can be applied on gypsum walls

Yes. Gypsum can be applied directly on the brick substrate. Rough Plastering is not needed until the thickness of gypsum goes above 1 inch.

Gypsum Plasters have a higher compressive strength than cement. Cement acquires strength from water curing, while on the other hand gypsum gets its strength when mixed with water at the right time and in the right proportions. Gypsum has a higher breakpoint and a greater strength as it is a naturally occurring rock. 

Before Cement was discovered, gypsum and limestone plastering were the common plastering methods. Limestone was commonly used during the pre-cement era because it was cheaper and widely available. Yet limestone plastering is inferior in quality. Gypsum has been a premium plastering method used in developed nations since then. Egyptian pyramids to all major buildings including Burj Khalifa and Petronas Twin Towers of Malaysia are done with gypsum plastering. It lasts multiple generations and has a better life than cement.

No. Gypsum is not a material that is used to bond two different substrates. Gypsum can be applied over mortar joints,  but not as mortar joints. 

Yes. It has major 4 benefits. It saves at least Rs.35/square feet in cost apart from saving 75% of construction time. Gypsum plastering does not need water curing,  and has no shrinkage cracks.  Gypsum keeps the room cool, has better acoustic properties and is fire resistant as well. Cement lags behind in all these.

Gypsum is a naturally occurring mineral. It is mined, powdered and heated to high temperature to lose water. Then it is stored in bags. During application, when mixed with water, it gets back to the natural rock formation. 

Yes, Gypsum plaster is completely recyclable and environmentally-friendly.  Gypsum is also an integral part of green buildings certification. Gypsum plaster’s main constituent is stucco, obtained from mines after heating the gypsum rock that goes back to its original form providing required strength after adding water to it.

The paint surface should be hacked and sandblasted before applying paint. The same procedure that we follow to apply cement on paint works for gypsum as  well.

Yes, applying primer is a must before painting. Primer increases the bonding between gypsum and paint, while increasing the life of the painted wall.

The minimum thickness of gypsum plastering is 2mm and the maximum is 24mm. If it is above 24mm, the surface has to be prepared before applying gypsum. At Kanish Plasters, we have quality checkpoints and norms to ensure life and consistency.

Yes. All major builders have already shifted to gypsum and several government projects are already on gypsum. Kanish Plasters is the only gypsum plastering vendor for several government projects. 

Gypsum is a naturally occurring recyclable material. It helps save energy at home because it is heat resistant. During LEED certification of green buildings, gypsum plastering has points that add up for certification. All major certified green buildings use gypsum plaster.
