Latex-based paint can last up to ten years, but its shelf life is influenced by the can’s condition. Opened cans typically last less due to bacteria growing in the paint, which need specific conditions like darkness, moisture, and heat. These bacteria can be found in closed paint cans in garages, sheds, or basements. Modern, low-VOC or zero-VOC latex paint is more likely to be ruined after a few years due to bacteria growth.
