Can You Use Exterior Paint Inside?

When it comes to painting, one question that often arises is whether you can use exterior paint inside your home. The short answer is yes, you technically can, but it’s not recommended.

Understanding the Difference

Exterior and interior paints are formulated differently to meet the unique demands of their respective environments. Most interior paint is acrylic latex, which is water-soluble when wet, low-odor, and emits a minimal amount of volatile organic compounds (VOCs). It’s engineered to be washable and scratch-resistant.On the other hand, most exterior paint is also acrylic latex but with added resin to make it weather-resistant. It’s designed to withstand rain, intense heat and sun, freezing temperatures, and even resist mildew, fading, and staining. Some brands label it “acrylic enamel”, referring to the gloss finish.

Why Not Use Exterior Paint Inside?

While exterior paint will dry indoors, it’s not advisable to use it for your interior walls. The additives in exterior paint that make it resilient outdoors are not intended for use inside. The more intense levels of resin used in exterior paint are intended to cure and age outdoors where they will not affect indoor air quality.Exterior paint contains a higher number of VOCs than interior paint. This means that the paint’s off-gassing will be smelly at best and potentially hazardous at worst. It’s especially true for people with allergies, breathing problems, or chemical sensitivities. Even after it dries, exterior acrylic latex will continue to emit VOCs.

Remember, it’s not just about the color or finish of the paint, but also about its composition and the impact it can have on your health and the durability of your walls.
