Shelf Life of Paints
Q. Does interior latex paints have a shelf life?
A. All paints have a shelf life; some shorter and some longer. Waterborne paints
such as household (or house) latex paints have a shelf life of six months to
one year, depending on ambient temperature conditions. Once you have opened
the can of paint, the shelf life may be shorter. Even though the published shelf
life of the paint you intend to use may have expired, that does not automatically
mean that you should discard it. If the paint appears to mix properly and does
not show signs of livering, separation or anything else unusual, you should
still be able to use it.
