Home  /  The plaster

A ready mix in a 25 kg bag. Add water, lay it on bare brick.

One bag replaces three products: cement plaster, wall putty and primer. It lays like a plaster and finishes as it comes off the trowel.

At a glance

What you are buying.

25 kg bag, ₹265
Dry powder, ready mixed. Covers about 18 sq ft at 10 mm.
Just add soft water
About 10 litres a bag. Any mason who can lay plaster of paris can lay this.
Cured in 2–3 days
Against seven days of water curing for cement plaster. And no water curing at all.
No hairline cracks
It does not shrink the way cement does, so there is no crazing to bury under putty.
Mosquitoes keep off it
A property of the material, with no spray, coil or coating involved.
Matt khaki finish
Most people leave it as it is. Lime wash over it if you want a different colour.

Where not to use it

Three jobs to use something else for.

Anything structural
This is a finish, not a binder. It does not replace cement in concrete, mortar, columns or slabs.
Permanently wet surfaces
Shower enclosures, sunken bathroom areas and water tanks need a waterproofed cementitious finish.
Exposed external walls
Interior and sheltered walls only, for now. A weather-graded version is in development.

Common questions

The things everyone asks first.

Does it smell?
Not once it is dry. The dung is processed and dried before blending. There is a faint earthy smell while the wall is wet, which goes as it cures.
Is it hygienic?
The dung is dried and heat-treated at the plant before it enters the mix, and the formulation works against mould and insects on the finished face.
Can I paint over it?
Yes, but lime wash suits it best because it stays breathable. Conventional emulsion will stick, though it seals the surface and gives up some of the benefit you paid for.
Can my regular mason apply it?
Yes. No new tools. The one habit to break is water curing — this material does not want it. Full method on the how to apply page.
How long does it last?
Gypsum-based plasters have service lives measured in decades. We were founded in 2025, so we cannot show you a twenty-year-old wall of our own yet — we can show you the reference sites we are building now.
Where can I buy it?
