Humidity is the amount of water vapor that is in the air. The higher the humidity, the more water vapor present. This can hinder painting projects in a big way, as the water from paint needs to evaporate for it to dry to a hard surface.

If condensation occurs on the surface of the painted area, this can damage the paint finish and ultimately, ruin the look of the project.
