Can I spray latex paint on the decorated room in rainy days?

The coating process of latex paint is divided into film-forming period and drying period, which are almost synchronous under reasonable air humidity, that is to say, latex paint is gradually dried while forming film.

On the contrary, if the air humidity is too high, the drying time will become very long. After the film-forming period has passed and the latex paint is not dry, it will affect the film-forming process and lead to powder on the latex paint wall in the future.

Generally speaking, when the air humidity is less than 85% and the moisture content of the base is less than 10%, latex paint can be painted. The air humidity is generally around 50% on sunny days and around 80% on cloudy days. If it is spring and autumn, this value is even higher, so it is best not to brush latex paint on cloudy days, let alone rainy days.
