The calcium oxide reacts with carbon-dioxide to form calcium hydroxide which makes a shiny white layer on the wall.

When Calcium Oxide is combined with Water it forms Calcium Hydroxide

Equation:

CaO + H2O ---> Ca(OH)2

When Calcium Hydroxide is painted on the wall, a layer of Calcium Carbonate is formed within 2-3 Days, as Calcium Hydroxide reacts with Carbon dioxide to form Calcium Carbonate.

Equation:

Ca(OH)2 + CO2 --> CaCO3 + H2O

Hope it helps you!
