Paint’s durability varies by type. Typically, paint lasts from one to ten years before spoiling. Unopened paint, when stored correctly, can last for many years. Water-based and latex acrylic paints can last up to a decade in storage. Oil-based and alkyd paints, however, can last up to fifteen years. If the paint can remains sealed, the components may separate over time. This separation isn’t due to environmental factors. Even insulated cans can be damaged if stored in a garage or shed and exposed to freezing or severe weather. We’ve compiled frequently asked questions about paint lifespan to help you understand it better and learn how to store paint properly.
Can Old Paint Still be Used?
Sometimes, yes. Open the can to check it’s condition. If the paint looks good and smells normal, stir it well. If there’s a lot of sludge or bits that won’t mix in, it’s best not to use it. A layer of dried paint,however,means air has entered the can,drying the top layer. You can try to salvage it by removing the dried layer. Than, mix the paint thoroughly and apply it.
How to Tell if the Paint Has Gone Bad?
If your paint is thick, spongy, or smells bad, it’s likely spoiled. Repeated freezing and thawing can make paint lumpy, preventing a smooth finish on your walls. Paint with a foul odor likely has bacterial contamination and should not be used. If it smells bad in the can, it will smell bad on your walls. Discard it and buy a new can. Separated paint can often be used.Simply turn the can upside down a few times, stir gently, or use a paint stick to revitalize it. If you’re unsure, consult a paint store expert.
How to Store Paint?
Store leftover paint in a temperature-controlled area between 50 and 90 degrees Fahrenheit.Avoid freezing temperatures (like in a garage) and excessive heat (like in an attic). Keep it away from heat sources like water heaters, furnaces, or direct sunlight. If you have little paint left and limited storage, pour it into a smaller, repurposed plastic container with a twist lid. Keep the label or lid with the product number, color, and acceptance details. This details is crucial for touch-ups or future projects.
what to Do with Leftover Paint?
If the paint is still good, save it. Keep latex paint fresh by storing it in an airtight container to prevent water evaporation and bacterial contamination.You can keep it in the original can or transfer it to a clean jar with a screw-on lid. Store it at room temperature, avoiding garages or sheds due to temperature fluctuations. Label the paint to remember its use. if the paint is unusable, dispose of it properly. Check your local government’s website or contact your public works department for disposal instructions.
How to Extend the Shelf Life of Paint?
To maximize shelf life, store paint indoors, away from extreme temperatures and direct exposure, whether it’s for touch-ups or excess paint. Place plastic wrap over the top of a half-empty can to maintain freshness, then secure the lid with a hammer. Note the date and color on the side for future reference. Unopened paint cans can last for years when stored correctly. Water-based and latex acrylic paints can last up to ten years if properly mixed before use.Oil-based and alkyd paints can last up to fifteen years. Over time, the composition of liquids and semi-solids in unopened cans may separate due to the lack of environmental exposure.
