It is to be applied as a protective and decorative first coat on freshly plastered walls to give it a glowing milky white look. It has been developed keeping in mind, needs of house owners and builders under Indian conditions. Usually people do not plaster and paint the exterior of a new house or building right after construction either due to budget constraints or just to check construction defects till one rainy season has passed. Till that time, usually lime wash or white / grey cement wash is done. Wonder White is a better substitute due to its better whiteness than white cement, 20% higher coverage than cement wash and better adhesion due to unique formulation.
