This is a topic frequently posed to professional painters: how long does interior paint remain on the wall? However, it is practically hard to answer this question. A well-executed interior painting project will typically last between 5 and 10 years, and sometimes even longer.
When inside paint is opened, how long does it last?
All kinds of paint ultimately go bad, thus the answer is yes. If properly sealed and kept, a paint can that has been opened typically lasts five years. The shelf life of used paint varies depending on the kind of paint. In particular, latex or acrylic paint cans can endure up to ten years if they are not opened.
Oil-based or alkyd-based paints have a shelf life of up to 15 years if they are not opened. In addition, milk paint only lasts 1-2 weeks after mixing, while chalk paint has a shorter lifespan of 1-3 years. However, the type of paint being stored and the storage circumstances affect how long paint lasts.
Unsealed paint won’t survive more than a year or two in a garage with cold temperatures.
How long is the life of paint? – This depends on whether suitable storage conditions were maintained. New, unopened cans of latex or oil paint typically have a shelf life of roughly three years. If you keep an opened can of paint correctly and don’t expose it to air, it may last up to two years.
Does paint have an expiration date?
A properly managed unopened can of latex or oil-based paint should have a two-year shelf life. Paint should be stored in a cool, dry location, away from excessive heat and cold temperatures. Never allow paint to freeze, and always keep it away from furnaces and other heat-generating equipment.
