In particular, an unopened can of acrylic or latex paint lasts up to 10 years. In the case of unopened oil-based or alkyd paints, the lifespan can be up to 15 years. In addition, chalk paint has a shorter lifespan, 1 to 3 years, and milk paint only lasts 1 to 2 weeks after mixing. Open paint cans don't last as long, but if the can is sealed after painting and stored in a cool, dry place, such as a heated garage or basement, the paint can last for years.
