Curing is a term associated with the process of paint drying on a surface. However, cured paint is different from dried paint as it is achieved by a change of the chemical levels in the paint. Cured paint must be left to ‘dry’, become solid and bond with the surface. It can take anywhere from a few days to a few months for paint to become cured depending on the type of paint used.
Paints that are applied to non-porous surfaces - such as glass paint on glass - benefit from a long curing period.
