How Long Can Paint Be Stored Once Opened

Generally, an open can of paint can last anywhere from two to five years. If you store it carefully, your open can of paint could last longer than that. Both opened and unopened latex paint has a shorter life span than oil-based paint. A can of oil-based acrylic paint that's been properly resealed can potentially last up to 10 years in storage. However, it's important to note that oil-based acrylic paint can dry out quickly if the can isn't completely resealed. As it dries, this type of paint releases flammable fumes into the air that can become a fire hazard. You need to exercise extreme caution when resealing and storing this type of paint.
