How Long Is Interior Paint Good For?
Does Paint Go Bad? – Yes, all paints ultimately go bad. The typical shelf life of a previously opened can of paint is five years when properly sealed and kept. The shelf life of old paint might vary depending on the type of paint. Unopened latex or acrylic paint cans have a shelf life of up to 10 years.
- Unopened oil-based or alkyd-based paints may have a shelf life of up to 15 years.
- In addition, chalk paint has a shorter lifespan of 1 to 3 years, whereas milk paint only lasts 1 to 2 weeks after mixing.
- However, the longevity of paint depends on the type of paint and the storage circumstances.
- Unsealed paint kept in a garage with freezing temperatures will not survive longer than one or two years.
Extreme temperatures have the same effect on all types of paint. This covers Sherwin-Williams, Dulux, Glidden, Kilz, Zinnser, Benjamin Moore, and Behr paints and primers. In the next part, we will discuss how to correctly store paint and how to dispose of it.
How can you determine if inside paint is still in excellent condition?
Unopened Paint – The good news is that if you have an unopened can of paint that has been properly preserved, it is almost certainly still usable. Latex and water-based acrylic paints have a shelf life of up to 10 years, whereas alkyd and oil-based paints have a shelf life of up to 15 years.
- Because unopened paint retains its mix of liquids and semisolids, it is safe to use even after a lengthy period of time.
- This ratio begins to alter after the container is opened and exposed to air.
- Before you use that 5-year-old can of paint in your home, it is imperative that you test a tiny area.
- Given how long the paint has been sitting, it is possible that it has split.
The materials must be well mixed with a paint stirrer for at least five minutes. Mix the paint before testing it on a piece of cardboard. If the paint seems regular and applies evenly, you are ready to begin painting! If you observe lumps or grains that cannot be stirred out, the chemical composition of the paint has altered and it cannot be utilized.

How long does paint from Behr last?
Latex or Acrylic-Latex Paint – Typically, paint company estimates of paint shelf life are cautious. According to PPG, the maker of PPG Paints and Glidden Paints, the shelf life of an unopened can of latex paint is two years. Sherwin-Williams predicts a one-year shelf life for several of their paints.
The Remedy for Odorous Paint – Without a doubt, if something smells terrible, it is bad and should be thrown. Most latex paints have a shelf life of up to 10 years, although paint can go bad in considerably less time if it is improperly handled. Poorly applied paint may leave a finish that is obviously harsh and may peel.
- The most prevalent cause of odorous paint is bacteria, which can be introduced during the manufacturing process, when colours are applied at the hardware shop, or when a partially used can is kept.
- Low- and no-VOC paints are especially susceptible because they contain less solvents, which not only stabilize paint but also inhibit bacterial growth.
To verify whether a can of paint is still useful, pry off the lid and smell the paint with a screwdriver. Good paint will have a chemical odor, but not a putrid odor as yours had. Obviously, moldy paint should be discarded promptly. Mix the paint using a stirring stick if it has begun to split into liquid on top and denser pigments below the surface.
- It is acceptable for usage if the components combine easily.
- This is true even if you must remove a thin layer of paint off the surface.
- If there is sediment at the bottom that will not mix with the paint, the can must be discarded.
- For paint that dries with a lingering odor, wash the walls with a solution of 1 part water to 10 parts water, then rinse with plain water and a clean sponge.
Permit the walls to dry thoroughly. Follow with a primer that seals odors, such as Kilz (kilz.com) or BIN Advanced (rustoleum.com), a synthetic shellac sealer. Before applying new (unspoiled) paint, it may be necessary to apply two coats. Tags: A Remedy for Odorous Paint
Does paint have an expiration date?
A properly managed unopened can of latex or oil-based paint should have a two-year shelf life. Paint should be stored in a cool, dry location, away from excessive heat and cold temperatures. Never allow paint to freeze, and always keep it away from furnaces and other heat-generating equipment.
