Semi-gloss or gloss finishes will give some shine that helps the paint resist absorbing extra moisture that leads to mildew growth. Semi-gloss paint includes more resin and binders when compared to flat paint, and a glossy finish bumps up the amount of resins even more. As a result, you get a very tight molecular structure in these paint formulas. Higher gloss paint will repel moisture. Rather than absorbing moisture and giving it a chance to collect and develop into mildew and mold, a wall painted with semi-gloss or glossy paint is more likely to see moisture evaporate away.
