Solution used to white wash the walls is Quick lime(CaO) and when it is mixed with slaked lime [Ca(OH)2]. When this paste is used for white washing it combines with atmospheric CO2 to form calcium carbonate (CaCO3) which gives it a shiny texture.
Slaked lime or Ca(OH)2 is used for white washing the walls. But when Ca(OH)2 react with CO2, it gives Calcium Carbonate and water which gives a smooth finishing to the walls. ...
