Seal it Up
Seal the paint can properly before you put it away to keep the paint from drying up. If any paint has gotten in the grooves of the paint can wipe it with a clean rag. Use a rubber mallet to tap the lid down securely. Don’t use a hammer – it can distort the lid, making it more difficult to securely seal the can. If you don’t have a mallet, you can cover the can with a piece of wood and then hammer the lid closed.

Location
Store paint in a cool, dark location like a basement. If you do store it in the basement, make sure that it’s on a shelf. Moisture from basement floors can rust your paint cans. If you don’t have a basement, place them in a cabinet or closet in your house. Extreme hot or cold temperatures can ruin the paint. Cold weather can cause latex paint to separate, making it unusable. Heat can dry it out. Very hot temperatures can even trigger a fire with oil-based paints.

Space Savers
If you have cans that are halfway or almost empty, transfer the remaining paint into quart cans or large jars. Then use some labels and a marker to list the brand, paint name, date of purchase, mixture number and the room that you painted. Place a small dollop of paint on the top or side of the can too easily identify the color. If you have more than one color for a room (such as wall color and trim), keep them together. If you’re feeling especially organized, you can use a label maker and mark each room on the shelf front.

Reopening a Can
Opening a paint can after it’s been sealed for a long time can be difficult. But avoid using a screwdriver to open it. The lid can become warped and it will be difficult to seal it in the future. Use a key that’s specially designed for opening paint cans. Lowe’s will give you one for your paint purchase.

Shelf Life
Latex or water-based paint typically has a shelf life of ten years. The solvent or oil-based paint can last up to fifteen years. You can test to see if your paint is still good by doing the following:

  • Latex – First, smell it. Does it smell rancid? If it does, it’s gone bad. Secondly, check to see if the paint is separated. There will usually be a thin skin on top with a layer of liquid underneath. Remove the skin and using a paint stick, stir the paint. Check to make sure that the paint isn’t hard on the bottom or the sides. If the paint blends together smoothly and appears to be the original color, then it’s OK to use. If you’re still unsure, brush some of the paint onto a piece of newspaper. If the paint comes out rough and lumpy, you need to dispose of it.
  • Oil-Based – If it hasn’t been exposed to extreme temperatures and was sealed properly, then oil-based paint typically isn’t as susceptible to going bad as latex. Just remove the layer of film across the top and stir it well before painting.
