Firstly, always check the paint with the points below but with proper storage, you can often use emulsion paint up to 6 months old but it really depends on the brand of emulsion and how the paints been stored.

There are a couple of ways to tell that emulsion paint has gone off. When was the last time you used the paint? If it was 5 years ago when you originally moved in then just buy a new tin of emulsion. Just be aware that even if the paint smells fine once applied you may start to smell a souring scent as it dries.

What I mean by that is a room that is not affected by constant heat changes. The perfect place is under the stairs or in a cupboard off the hallway. Avoid places, where there are constant heat fluctuations such as outdoor storage sheds or storage boxes as the heat and cold, can cause the paint to expand and retract. This change will sour emulsion paint a lot faster than proper storage solutions.

Unopened cans of paint last for years when stored correctly. Unused latex and water-based acrylic paints last up to 10 years, and the shelf life of alkyd and oil-based can be as long as 15 years. But if you stored the can in the garage or shed where it froze or was exposed to extreme heat, even fully sealed contents could be ruined.

Pry open the can and blend the contents thoroughly with a paint stirrer. Dip a brush in the paint and brush it onto a piece of cardboard. Go ahead and roll that wall. Because opened cans of paint are exposed to air, they often develop a thickened skin on the top that should be removed with a paint stick before attempting to stir the paint left in the can.
