How Long Does Paint Last? 6 Signs It’s Time to Toss
One of the best ways to reduce the cost of a painting project is to reuse leftover paint from previous jobs around the house, but how long does paint last?
As long as paint is stored in a cool, dry location using an appropriate container that has been properly sealed, it can usually last several years after being opened. So, even if there aren’t any immediate plans to paint, it’s a good idea to store extra paint instead of disposing of it.
However, paint doesn’t last forever. The contents can begin to dry, the ingredients can separate, and the paint can become chunky and sour-smelling. Rust and corrosion on the can are signs that the paint is no longer good.
Similarly, mold or mildew growth inside the paint can indicate it’s time to toss it.
