My cousin was painting his house and told me there was some extra primer left. He asked me to return it to the store. When I went to the store to return the primer, I asked the shopkeeper, does paint primer expire? He told me while an unopened primer can last several years, sometimes up to 10, it does eventually expire. Once opened, its shelf life is shorter, usually around 2 to 3 years if stored properly.

How Long Does Paint Primer Last?
As I mentioned earlier, the shop owner said an unopened can of primer can last for several years, but it will eventually expire.
He said primer plays a key role in helping the paint stick properly. It forms a solid base on the surface and makes the paint last longer and stay in good condition.
Primer seals porous surfaces so the paint doesn’t get absorbed unevenly.
It also blocks stains and odors from showing through the final paint layer.
According to him, primer makes paint go on more smoothly and evenly. It reduces the number of coats needed.
He also mentioned that using a white primer close to your paint color helps you get the perfect shade you want.
I hope this will help you.
