When it comes to old paint, there are several options for storage and disposal. Here are some tips from the search results:

Storing Paint:

• If you have cans that are half or almost empty, transfer the remaining paint into quart cans or large jars. Use labels and a marker to list the brand, paint name, date of purchase, mixture number, and the room you painted. Place a small dollop of paint on the top or side of the can so you can easily identify the color. If you have more than one color for a room, such as wall color and trim, keep them together.

• Latex or water-based paint typically has an unopened shelf life of 10 years. Solvent or oil-based paint can last up to 15 years unopened. You can test the paint to see if it’s still good by smelling it and checking to see if its separated. If the paint blends together smoothly and appears to be the original color, then it can be used. 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.

Disposing of Paint:

• If you have a small amount of paint to dispose of, you can pour it onto a newspaper-covered surface and let it dry. Once its dry, you can throw away the newspaper, dried paint, and the can.

• Another option is to pour the paint into an absorbent material such as shredded newspaper or kitty litter. Allow it to completely dry, and then dispose of the dried paint in the trash.

• When disposing of any hazardous waste materials, it’s crucial to always keep them in their original containers, never combine them with any other hazardous waste materials, and always follow the labeled disposal instructions to avoid injury and environmental harm. If you have a decent amount of usable paint, donating it might be a valid option to pursue. Organizations like Habitat for Humanity Restore, your local community center, or another nonprofit organization are good places to check with. They may have an easy curbside drop-off site nearby or a collection event that repurposes leftover paint in a much better way than sending it to a landfill. Paint recycling programs, such as PaintCare, is a stewardship that follows HHW laws and will help find a solution in your area.

• If you don’t have enough water-based paint or latex paint leftover to give away or store, you may be able to dispose of paint through your household trash collection. Call your provider to ensure they pick up paint that’s dry. If so, they’ll likely have you brush the leftover liquid paint on cardboard or newspaper, and allow the empty can to dry with the lid off.

Remember to always practice lead paint safety, and if the house or surface youre painting was built before 1978, see EPAs renovation, repair, and painting program for guidelines.
