Shelf life under normal conditions is two years unopened. Partially used cans might develop skinning if not tightly sealed.
How do I know when primer is safe to paint over? If it is kinda sticky, then it is too soon. It should be dry as in really dry. Wait until it is completely dry. Even when it's dry to the touch, it's not completely dry. Spray primers usually have instructions on the can, including drying times.
Unfortunately the quality of primer degrades at a considerably faster rate than that of your standard paint once opened, but if left unopened the product should last for around 10 years. Once opened, you may get around two years out of your primer purchase.
Oxidation: Primers can start to break down when exposed to air for too long. This process, called oxidation, can affect the primer's ability to bond with your paint.
Primer can go bad just like regular paint, and it has a much shorter shelf life. Most primers have a storage life of two to three years, considerably less time than a paint can.
Open cans of paint don't last as long, but if the can is sealed after painting and stored in a cool, dry location, such as a heated garage or a basement, the paint can last for years. On average, paint lasts about ten years before it needs to be tossed, although some paint products may last up to fifteen years.
Sealed primer that has been properly stored (meaning it's kept in a cool, dry place, away from direct sunlight), can last for 2-3 years. It hasn't been exposed to air or bacteria, which are the main culprits in breaking down cosmetic products.
The label of many beauty products features a small jar with a number and the letter M next to it that denotes how long that product will last after you open it. For example, 3M means three months, 6M means six months, 12M means a year, etc.
We would advise researching local paint disposal regulations. Many areas have local household hazardous waste drop off sites that will collect old and unwanted paint.

It's recommended that you replace mascara every three months, lipsticks every year and eyeliner every three to six months (though pencils last longer than liquids). Primers and foundations usually last about two years, Zeichner said, and powdered products like blush and eye shadow are typically the same.
Primer - Primers can last anywhere from 6 months to 24 months. Face primers: around 12 months, some even up to 24 months. Eyeshadow primer: 6-12 months.
Once opened, most paint products, including Benjamin Moore, have a shelf life of two years. Considerations include environment, temperature fluctuations and other variables.
While primer is an important step, it's not always necessary. You don't need to use a primer if your paint project has all of these conditions: You're painting drywall surfaces that are smooth, clean, and don't need repair. Surfaces were previously painted with latex in a flat or eggshell finish.
How Do I Paint Over Painted Walls? If the wall is in good condition and the paints are chemically the same (both latex, for instance), you have a few options when the new paint is the opposite shade of the old paint. You can use a primer to thoroughly cover the old color, then apply 1 or 2 coats of the new paint.
Using too much primer may make your skin slippery and oily, especially if you're using a product containing silicones or hydrating ingredients. Be careful with colour-correcting primers, focusing on areas of discolouration. If you use too much of a green primer, you may look sickly.
Can You Use Old or Spoiled Paint? In many cases, paint stored away from extreme temperatures and humidity is still useable long after its listed shelf life. If your paint doesn't have a spoiled odor or consistency, you can use it for touchups or new projects—though it may not result in a perfect finished product.
