"It will say on the tin but as long as it’s airtight it can last for years , it will more than likely need to be re- mixed to be used"

"In quality dependency sometimes after a year it will be thrown away and some will still be good after years. A difficult question, as it can be influenced by many factors such as temperature, frequency of temperature changes, humidity, sunlight, etc."

"Hi there, a new unopened tin of paint can last around 2-3yrs if u do open a tin, as long as its closed properly and not exposed to air it can last a year or too

Hope this helps :)"

"Don’t need to be left unopened
Bang some cling film over the lid hole/tray
This will keep the air out
Also good for wrapping brushes and rollers to be able to use and carry on the same colour the following day"
