Leftover paint can last up to ten years, depending on the type and quality of paint used. It is important to store it in a dry place out of direct sunlight, away from children, and away from food and drink. Latex paints like AURA®, REGAL®, and ben® should be stored either in a lined metal can or a glass or plastic container to prevent rust.
Unopened cans of paint can last for years when stored correctly, with latex and water-based acrylic paints lasting up to 10 years, and alkyd and oil-based paints having shelf lives of up to 15 years. If you live in a cold climate, it is best not to store latex paint in a garage or storage space that’s not properly maintained.
The shelf life of paint depends on several factors, including the type, quality, storage conditions, and exposure to elements. Unopened latex and oil-based paints last up to 10 and 15 years respectively. To make leftover paint last longer, follow these organization and safety tips:
- Store the can within an hour or two after use and use the paint within a year.
- Latex-based paint can go bad over time, but it can last up to ten years if fully sealed. A can that has been opened and properly resealed may easily last a decade in storage, while unopened paint can last up to 15 years.
- Oil-based paint has the highest shelf life, but it can also go bad in just months. To ensure the longevity of your paint, it is essential to follow proper storage guidelines and maintain proper storage conditions.
📹 How to Store Paint Properly | How Long Does Paint Last?
How do I know if paint has gone bad?
Old paint can be a sign of deterioration, with a harsh smell, physical changes, or separated solutions. If these signs are present, it is likely that the paint has expired. If the paint has separated into semi-transparent and opaque liquids, it is no longer suitable for use as the solvent and pigment won’t work together to stick to the wall.
To dispose of old paint, it is recommended to contact regional governments for programs to help people dispose of it, or donate it to building charities if it hasn’t expired yet. To avoid leaving leftover paint, it is recommended to contact local professionals like Five Star Painting, who can handle both inside and out painting projects and provide a thorough cleanup after the job. To schedule an appointment, call 261-3633 or schedule an appointment online.
Is paint still good after 20 years?
The typical lifespan of latex paints is 5-10 years, while oil paints have a longer lifespan of 10+ years. In the event that one is required to dispose of aged paint, it is advisable to contact the relevant county authority for further details. Should assistance be required in the execution of a painting project, we would be pleased to offer our guidance.
Does paint go bad if never opened?
Unopened cans of latex or oil-based paint have a two-year shelf life when stored in accordance with the following conditions: in a cool, dry area, away from extreme temperatures, furnaces, and heat-generating appliances; and never allowed to freeze.
Is it OK to store paint in the house?
Store paint indoors in a utility room or under stairs cupboard, away from radiators and direct sunlight. Exposure to extreme temperatures can cause paint to dry up or separate, making it unusable. To store paint brushes correctly, scrape off excess paint using a paint brush and roller cleaning tool. Soak water-based paint in warm water for a couple of hours, or oil-based paint in white spirit or a solvent-based brush cleaner for a couple of hours. Rinse and dry the brushes with an old cloth, and store them in a clean, dry place. This will prevent the need for new brushes for every paint job and prolong the lifespan of your paint supplies.
How long can house paint sit?
Homeowners often have partially-used paint cans in their basement, garage, or shed. The average lifespan of these paints depends on factors such as the type of paint, usage, and storage location. Oil-based paint lasts for 2 to 5 years, acrylic paint lasts for 5 to 10 years, oil-based paint lasts for 5 to 10+ years, and chalk paint lasts for 1 to 2 years. Experts like Ed Edrosa, senior project manager at Behr, Dennis Fiorilli, director of product excellence at Sherwin-Williams, and Brandon Walker, superintendent at ASAP Restoration, can help determine if last year’s can has gone bad and how to ensure paint stays fresh for as long as possible.

How can you tell if paint has gone bad?
To determine if paint is old, smell it for mold or unpleasant odors. If mold grows inside a can, it’s a health hazard. If the paint has an ammonia smell, it’s still good. Stir the paint well and strain it before use. Check the cans to identify the date of mixing and add at least one year to the date due to potential manufacturing delays. Higher-quality paints last longer and can be reused, while cheaper ones don’t. Latex paints typically last 5-10 years, while oil paints last 10+ years. If the paint lasts longer, you may need to buy new paint.
How long can you keep paint once opened?
Unopened paint cans last around 10 years, while an opened and resealed can lasts about two years. The shelf life of paint can vary depending on the type of paint and other factors. Resealing is crucial as paint degrades in oxygen and moisture, and a tight seal can lead to a two-year shelf life. Storage conditions also play a significant role in paint’s shelf life. A consistent temperature of 60-80 degrees Fahrenheit is recommended to prevent freezing, drying out, or thickening.
Is 10 year old paint still good?
Water-based latex paint is a popular choice for interior painting projects due to its lower preservative content and longer shelf life. It can last two to ten years, depending on storage conditions. To extend its lifespan, avoid storing it in uninsulated areas susceptible to summer heat and freezing winter temperatures. Acrylic paint, while less freezing-prone, dries up quicker when exposed to open air, so proper sealing is crucial. It can last two to ten years when stored properly.
Oil-based paint, with its longest shelf life, can last up to fifteen years when stored in a cool, dry location. However, it can be opened and resealed multiple times, potentially reducing its lifespan. Proper storage and proper sealing are essential for maintaining the longevity of these paints.
Is it safe to store paint in the house in winter?
Paint storage is crucial for a successful paint job, as it requires careful consideration of room temperature. Paints are best applied between 45 and 85 degrees Fahrenheit, and storing them in an environment with temperatures below freezing or exceeding 90 degrees can lead to damage. Ideally, paint should be stored in a room with a consistent temperature between 50 and 75 degrees Fahrenheit, such as a heated garage, basement, crawl space, or closet.
Excess air can also dry out leftover paint, so it’s essential to minimize air inside the container and prevent additional air from entering. This can be achieved by transferring leftover paint into a smaller container with an air-tight seal. If only a small amount of paint is used, it can be kept in its original canister with a durable plastic cling wrap.
Organizing paint can be achieved by labeling cans with key information such as the brand, product name, color name, sheen/finish, and date of purchase. It’s also helpful to note the room and surface(s) where the paint was used on to avoid confusion. Finally, smear a sample of paint on a small drawdown card to be stored in case of damage, loss, or theft.
Is it safe to store paint in the house?
To store paint safely, it is essential to keep it in a cool, dark area between 60 and 80 degrees Fahrenheit. If you live in harsh winters, consider a basement or closed cabinet or closet instead. Separate different types of paint, such as stains, primers, sealers, and spray paint cans, and organize them by room or finish. This will help determine the space needed for paint storage and the number of bins needed.
Organize paint and supplies in one spot, ensuring everything is ready for the next project. If there are no built-in shelves, consider assembling a durable metal shelving unit with caster wheels and shelf liners. Use open top or open front bins to corral smaller cans and supplies like brushes, rollers, and drop cloths. Stick to inexpensive plastic or acrylic containers for spills. Assign each shelf a purpose, such as supplies or type of paint, and label them or the bins to minimize guesswork.
📹 How To Store Leftover Paint So It Can Last Until You Need It
“Did you know that even the way that you open a paint can can affect the lifespan of leftover paint? Avoiding air entering the paint …
I have a can of Sherwin Williams latex paint. It is nearly full and had about an inch of water on top. I mixed it until it was smooth then painted a one foot section on the wall. It looks good but I don’t like the color as it is too dark. I bought a new can of Behr paint but it is way to light. I want to put some of the darker into the light color to bring it up to what I want. The SW paint is from 2013 but appears to be fine. Would I dare use it where it is so old because I don’t want it to end up sticky on the wall? Thanks for the article.
how about…… 1. moving paint to smaller can to eliminate extra space…2. shaking can periodically.. 3. adding an inert gas to remove oxygen.. 4. put in air proof container….5. adding a anti-bacteria additive.. instead this long article tells us that temperature is what makes it go bad.. I think everyone already knew this. great job on the article editing though…
The information on keeping the sealing surfaces clean is great. Keeping air out is not important. Keeping oxygen out is very important. When ready to close the can take a deep breath and hold it as long as comfortable. Exhale into the can and quickly turn away to inhale. This puts CO2 rich air into the can. Seal CO2 in and your paint will last indefinitely. You can also use a CO2 cartridge in a bike tire tool or drink carbonated. The ball bearings don’t sound like a good idea because they can rust in latex paint which will always have entrained oxygen. Marbles, however, do sound like a good idea.
Well explained, with good ideas. Leftover paint left in the can forms a peel of hard paint on top. To stop that, over the past few years I’ve been placing Saran wrap over top of the paint, so there is a physical boundary between the top layer of paint and the air above. When it comes time to reuse the remaining paint, I lift the Saran wrap off and there is no dry layer of paint on top (and fewer flakes of dried paint to contaminate the remainder). Works great.
I like the ‘masking tape pourer’. To save pouring left over paint into a smaller tin to reduce contact with air, I leave the left over paint in its original tin and put plastic film on top of the paint. Better still I cut out a circle of cardboard the same diameter as the tin, wrap it in plastic kitchen film and put that on top of the left over paint in the tin to keep the air in the sealed tin away from the paint. Feel free to add that idea to your article. All the best Tony.
Turn the paint tin upside down when storing so skin & air gap will be on bottom when reopening. We used to ask hotel receptionists if they had an old spare stocking or panty hose when decorating hotels, it served 2 purposes, they’re great for straining paint through for really fine, lump & dust free paint especially when opening old pre-used tins but most of all it gave you a chance to chat up the girls behind reception for a date 🙂 worked most of the time.
Another tip from down under in Australia . 1; mark the can with a “V” with the top of the “V” on the lid and continue the rest of the “V” down the sides . just line up the “V” when replacing the lid to the other 2 marks down the side. This way the lid should always be in the same location . Tip 2 spend a bit if time making a lot wider lid removal tool I have one for smaller cans and another for the larger cans that gives me a lot wider radius area of contact to engage the lid and prevent the problem you highlighted you get with a narrow screw driver type removal tool.
Instead of using a rubber mallet to hammer down the lid, I’ve been using a length of 2×4 (about 20″ long) to press the lid down. Put the can on the floor, set the lid in place, hold the 2×4 at each end and press lid into place as you work it around the perimeter. I find I have more control and do less damage to the can and lid.
I just recalled another thing that I have been using for decades. I keep jars (generally from intant coffee… Maxwell or so) and pour used fluids (mostly terpintine) that are used as thinners, brush clearners and so forth for reuse into them (Not Mixed, but Seperate jars of course!) The paint will settle to the bottom of the glass and the used fluid will swim on top. Every so often I empty as much of the used fluid that is now semi clear into a second jar (filter it through a clean rag) and store it for further use to clean brushes or wipe down a surface that needs to be cleaned before painting or possibly degreased. I wouldn’t necesssarily recommend it for thinning new paint to paint a new surface though, but if one wants to try it at their own risk 🤷♂..I have used this for diverse thinners and brush cleaning substances for decades with success and reduced the amount I had to buy of at least 50-75%. I’d rather use the saved money for good quality brushes and rollers IMO. I started this to recycle roughly 40 years ago (when no one was even talking about doing so) and found it to be worth the little additional effort as well as not having to dispose of those substances in fluid form. Back then we didn’t have the possibilities we have today to bring them some where. Just be sure to always close the jar tight so that the fluid does not evaporate and you can store the fluid of a longer time. One more Idea..you have paint to dispose of? Keep your sawdust, add it to the paint, let it harden and through it away.
Great advice …. I know because I have been doing much of it for the greater part of my life. In addition I have a recomendation. After preparing the can properly for storage as shown here I lay out an old newspaper, piece of cardbord or such and set the can on it upside down for a day or two to be sure that it is sealed properly. When verified, I store the can upside down until I need it again. With that the air is then actually then in the bottom of the can and can be reopend and used for years. Any skin buildup is now at the bottom of the can. I have been doing it this way for at least 40 years and it has always been sucessful until now. Clean preparation is a must. If you are a sloppy worker I would not recommend this for you. Happy painting.
Well that’s all good however anytime you have a metal container that comes in contact with paint, moisture or air….you have a environment for rust from the inside out on metal cans and lid with almost never come off or be destroyed trying to do so. The best solution…. But paint the comes in the newer plastic container s, non rust proof! Any used paint put in smaller plastic jars or containers. It will last a lot longer than metal.
Great ideas thank you. I do love that Wipe it Paint Squeegee and the tape best. I’ve dealt with the other vinyl pouring solutions but I have found that as I paint on my own (I have 2 apartments I lease) the paint on the inside of the can dries or thickens especially when I am cutting in. Both the squeegee and the tape make a lot more sense for me because my house is over 130 years old and I am cutting in around a lot of wood trim. It is beautiful but a pain in the ass and I take my time or I ruin the finish on the wood trim. Love the ball bearings but I would worry that they wood rust over time. I like the marbles idea so I will look into that.
Great tips. I always try to keep the paint can as clean as possible, but sometimes I get a little lazy, especially when I’m in a hurry. I like the idea of transferring to a smaller container when you have less than a half a gallon left for long term storage. And I learned the labeling lesson after painting my whole house after moving in. Trying to remember which can was for which room was really annoying.
Aside from keeping the paint can rim clean and free of dried paint dribble that keeps the lid from sealing properly, is the problem of rust. Most gallon paint cans are made of cheap metal that rusts over time. The rust flakes off, contaminating the paint. Some, but very few, paint cans have a plastic internal coating that eliminates this problem.
OK, for those of you with the DIY and safe working capabilities of a gnat, please ignore what I am about to say. Anyway, this will be MUCH to long for today’s “Clic Clock” or Twitter birds to read so that is one idiot filter already. Today’s “latex” paint isn’t latex. It is acrylic. That was point number one. Still paying attention? Point two is that acrylic paints oxidize in the presence of… wait for it… oxygen. You can WELD the lid on a half-filled paint can and guess what? There’s STILL oxygen trapped under the lid. It will STILL oxidize. Point number three. Just eliminate the oxygen before just putting the regular old lid back on. No fancy sealing necessary. How, you may ask? Dig out what any DIY’er worthy of the title already has laying around, a hand held propane torch. Direct the UNLIT “flame” end into the can and give it a blast of propane gas. I probably have to say UNLIT again because idiots are so industrious and might have read this far on their own or with assistance. Sometimes a group of them get together and mouth out the big words coming to some sort of semi-reliable consensus on content. This works because propane is heavier than air. It will invisibly force out all the air above the paint, replacing it with “heavy” propane. It takes VERY LITTLE to do this. And since it is heavier than air, even if you do not entirely fill up the half-empty can “airspace” with propane, enough will be there to settle down atop the paint layer, protecting it from the air (and oxygen) above as it sits on the shelf.
Great tips here.. I used to store paint in my heated garage but the metal cans always rust so I started keeping them in my basement furnace room which seems to work well. I know the moisture in the air causes the cans to rust but is there a cheap solution to preventing the cans from rusting? I may try wiping them down with WD40 or some type of oil or spray some type of dry sealer?
Excellent tips ! …. one more ? ….. add a small amount of the CORRECT thinner / solvent to the paint before sealing and store in a COOL place, like the basement ? … ( sheds and barns can get VERY hot in the summer ! ) hopefully your paint should last for YEARS ! ..( tried – n – tested ) …… DAVE™ ……………..
