If you paint on a damp day, what happens to the paint's curing time?

Explanation:
Humidity affects how paint dries and cures. When the air is damp, there’s more moisture around and in the film, which slows the evaporation of water or solvents in the paint and slows the chemical or physical setting that forms a hard film. This means the coating takes longer to cure on a damp day. Rapid drying would require dry, low-humidity conditions, not a damp environment. Bleeding refers to pigment or stain migration and isn’t the effect caused by humidity on curing. The paint will still cure on a damp day; it just happens more slowly.
