Is it possible to keep houses warm in winters and cool during summers without air-conditioning? Sure it is. A Haryana based scientist has produced a solution in the firm of Vedic Plaster. After much research and experiments he has developed a formula which can be applied by anyone who has access to cow dung! Though there is nothing Vedic about this Plaster but it is based upon the time tested traditional method of plastering of rural India. The special feature of the Vedic Plaster is that it can be used on cemented houses.
Dr Shiv Darshan Malik, a PhD doctor has worked as a consultant to Work Bank and various organizations of the like. Dr Malik owns a factory where this plaster is commercially produced. He claims that if this Vedic Plaster is plastered at the outer walls of the house, the house remains cool from inside even in the fierce hot weather, since it acts as an insulator. Dr Malik says that since cow dung mixed with mud and husk has been used extensively in rural area for ages, he has named it Vedic Plaster.
The Innovative Formula
Vedic Plaster is composed of cow dung and gypsum in 2:1 ratio, which when mixed in water creates a paste of plaster. This plaster when used at the walls of brick and mortar insulates the walls and do not allow heat to enter inside the house. The plaster also prevents dampening of houses.
Vedic Plaster Factory is in Rohtak
Vedic Plaster can be supplied anywhere in India from its factory in Rohtak, Haryana.
Question: Basically, what is Vedic Plaster?
Answer: As a kid, I remember my mother used to send me to get cow dung from the neighborhood to apply on the walls of our house. I used to wonder as why she does so. I have an experience of living in a mud house as well as in a cemented house and so I have an idea of the temperature difference in both the houses. In 2006, I got Vedic Plaster applied on my house walls and then I compared the difference in temperatures with cement plastered houses. I realized that houses with Vedic Plaster do not require any AC or cooler to keep the house cool. However, such houses remain cool in summers while warm in winters.
Question: Why only cow dung, please elaborate?
Answer: I have been a science student throughout, so there is a scientific reason to use it. The cow dung has large amount of protein in it that helps in binding of the bricks. Also it has equal quantities of fibre in it, which again helps in increasing the strength of the walls.
Question: How can a common man or a farmer have access to this plaster?
Answer: It can easily be made at home and if someone is not able to do so, then we have the facility of plaster supply from our factory in Rohtak. All one needs is some ingredients to prepare it.
Mix 20% of lime stone with 60% of mud along with 20% of fresh cow dung. This composition can make 5 kgs of Plaster, which would cost around Rs 42.
The cost of applying this plaster is around Rs 20 per square feet, however it does not include labor charges.
This plaster can be used for 2 to 3 storey houses at their outer and inner walls. In Rohtak the cost of 25 kg Vedic Plaster bag is around Rs 210. The special feature of this plaster is that it can be used for four to five years, after which it needs to be replaced with a new coating.
