Question:

What is cement based paint and why curing with water is required?

Best Answer - Chosen by Asker:

Cement paint is a paint made out of cement with different pigments and it is applied on the external walls of the house. Before applying the paint, the wall cement plaster needs to be saturated with water and the paint is applied on damp surface. The painted surface needs to be cured for 3 to 4 days for proper hydration of cement based materials, which give life to the paints in terms of performance and better aesthetics.
