The Durability of Different Paint Types

Oil Paint 

Overall all paint types, oil-based paints last the most, not only on your walls but also when stored. They can take up to 10 to 15 years to go bad. This is because of the same components that make it toxic for people when exposed to it for too long. 

Latex Paint

Latex paints can last up to ten years or less, depending on their conditions. The optimum circumstances would be a closed can, but if that’s not the case, make sure you leave it well sealed in a dry, open area, away from sources of spark or flame.

Primer Paint

Primer paint lasts even less than the other two mentioned priorly. The majority of primers have a two- to three-year shelf life.
