Acrylic paint is one of the best types of paint to use on your home's exterior. It's a durable paint that is also heat- and cold-resistant. While oil-based paint is also durable, it's prone to fading, making it not as good of an option if you live someplace with extremely high heat.

In most cases, an opened can of paint lasts between two and five years. If stored carefully, it may last even longer. However, the storage environment, temperature changes and other factors can impact the shelf life.
Open cans of paint don't last as long, but if the can is sealed after painting and stored in a cool, dry location, such as a heated garage or a basement, the paint can last for years. On average, paint lasts about ten years before it needs to be tossed, although some paint products may last up to fifteen years.
