Can Paint Primer Go Bad? Primer can go bad just like regular paint, and it has a much shorter shelf life. Most primers have a storage life of two to three years, considerably less time than a paint can.
Solvent-based paints have a 15-year shelf life. If you can stir it, it's probably okay to use (even if you have to remove the “skin” on the surface first). Latex has a shelf life of 10 years. If it has been subject to freezing, it may not be usable.

What's the shelf life of Liquid Latex? If left unopened with the original seal in ambient temperature, the latex will maintain its original characteristics for at least a year. After 1 year, the product does start to thicken up a bit but it doesn't dry out like it does when the lid is open.

Unused latex and water-based acrylic paints last up to 10 years, and the shelf life of alkyd and oil-based can be as long as 15 years.
