Paint Storage Temperature

Proper paint storage is crucial for ensuring its quality and longevity. Maintaining an optimal temperature is one of the most critical factors in storing paint. This blog post will discuss the importance of paint storage temperature and provide tips on how to safely store paint at home or in a commercial setting.


More often than not, you will always store your paint for another time when you’ll need it. This is because people tend to always buy more paint than they’ll need! It is common to store your paint away for touch-ups you will need down the road. This sounds easy, right? While it is, it can get a bit tricky, especially during the winter season. It is important to know paint storage temperature and how to store paint properly year-round.

Why is Paint Storage Temperature Important?

Storing paint at the correct temperature is essential for several reasons:

Quality Preservation: Paint exposed to extreme temperatures may alter its consistency, making it difficult to apply and decreasing its overall performance. To maintain paint quality, keep it stored at a stable and ideal temperature.

Shelf Life Extension: Proper paint storage can extend its shelf life, allowing you to make the most of your investment in high-quality paint. When paint is stored at the right temperature, it remains usable for longer, reducing waste and saving money.

Preventing Separation and Spoilage: When stored at improper temperatures, paint is prone to separation or spoilage, rendering it unusable. This undesirable outcome can be avoided with proper temperature control.

Safety: Storing paint at extreme temperatures, especially in hot conditions, can pose a safety hazard. Certain paints may release harmful fumes or, in extreme cases, combust spontaneously when exposed to high temperatures.

Paint Storage Temperature

Paint storage is important because not many people know where and how to store paint. Especially what the temperature of the room will be where the paint will be stored.

  • For example, if the paint you have is water-based, you should not store it in your garage or cellar. If you, by chance, do this, the paint will potentially freeze. That is why you should store paints at room temperature, like in a closet or storage locker.
  • Another example would be if your paint is oil-based or lacquer. In that case, you won’t have to worry too much about the temperature because, for these types of paints, it takes a lot more for them to freeze. Nonetheless, if possible, you should still store your paints at room temperature. This way, you will avoid any problems.

Although this may seem obvious, paint containers must also be stored properly. You should never store paint that has a damaged seal.

If so, you should pick up a new one at your local hardware store. If you don’t have an empty paint can, you can use a vacuum-sealed jar to store the paint. Before applying the new lid, make sure there is no leftover paint on the edges of the container.

When it dries, the paint will glue the can closed. If the lid is not 100% properly closed, air will get into the paint, causing the paint to dry up while in the can.

Ideal Paint Storage Temperature

Different types of paint have specific temperature requirements for long-term storage. Below are the recommended paint storage temperature celsius for common paint varieties:

Latex and Water-Based Paints

Water-based and latex paint storage temperature storage should be between 10 and 30 degrees Celsius (50 and 86 degrees Fahrenheit). Freezing temperatures can damage water-based paints, so store them in a climate-controlled environment to avoid extreme cold.

Acrylic Latex Paint

Oil-Based and Alkyd Paints

While oil-based paints tend to have a slightly wider temperature tolerance, storing them between 10 and 30 degrees Celsius (50 and 86 degrees Fahrenheit) is still recommended to ensure their quality.

Oil Based Paint

Aerosol Paints: Aerosol paint cans should be stored between 10 and 48 degrees Celsius (50 and 120 degrees Fahrenheit). Keep them within the manufacturer’s recommended temperature range to stay safe.

Tips for Proper Paint Storage

To maintain optimal paint storage temperature and ensure paint longevity, follow these tips:

Choose a Climate-Controlled Space:

When possible, store your paint in a climate-controlled room or storage facility. This will help maintain a stable temperature and protect the paint from temperature fluctuations.

Avoid Direct Sunlight:

Sunlight can heat paint containers and cause significant temperature increases. Store paint in a cool, dark place, away from direct sunlight.

Keep Paint Off the Ground:

Storing paint storage containers on a raised surface can protect them from moisture and prevent paint from freezing, especially in colder environments. Place paint cans on a wooden pallet, shelf, or other elevated surface for added protection.

Refrain from Overstocking:

Avoid storing large quantities of paint in a small area or stacking paint cans too high. Doing so can make it challenging to maintain a constant temperature and may impair their shelf life.

Inspect Your Paint Periodically:

Regularly inspect your stored paint to ensure it remains in good condition. Properly sealed containers, free from dents or damage, can help maintain paint quality.

Label all Your Paint Cans


If you have just completed an interior painting job by yourself or with the help of professional painters, it is vital to label each paint can with the room or areas in which you painted. This will allow you to stay organized and not have to open each and every can to check the paint colours and where you used them.

In addition, you should try to keep the paint colour code and the number shown. Then, if you need more paint, the paint store will know which paint to provide you with. If you need a paint alteration for the paint formula, that can be adjusted as well. Lastly, you should label whether you used the paint for an interior or exterior project. All this is to say that labelling is very important!

Other Tips For Paint Storage Temperature

Staying organized involves you know where and how to store paint properly. Keep it all in one area. Whatever you do, do not store it in your garage, especially during the winter season. The paint will definitely freeze due to the inclement weather and because most garages are not heated during that time period. Also, never store paint in a damp area, like your porch or cold storage.

The paint will potentially rust and ruin. Extreme weather conditions will always alter your paint formulas. Seeing as the weather constantly changes like a rollercoaster yearly, it is not an ideal place to store paint. For guidance, check the label on the paint can. It will show you the suggested storage temperatures.

How to Know Your Paint Is Bad

Latex paint in the cold garage doesn’t always have to be in the garbage. Before doing that, open the can and check its condition. Freezing ruins latex paint, but can survive a few freezing cycles. Leave the paint to adjust to room temperature (the recommended temperature to store paint).

Then, stir it well. If the colour appears normal, it will be okay to use. If it looks like cottage cheese, you should let it dry on a newspaper in a safe place. Then, you should dump it in the garbage.

Paint Storage Temperature

The paint storage temperature should be room temperature. You should not place your leftover paint in the garage, especially during winter, as it will freeze.

Also, you should never store paint in damp areas like your porch or cold storage. The paint will rust, and then you won’t be able to use it again. Using this information, you can continue doing interior painting projects in the future or with the help of interior painting services.

Taking care of your paint investment by maintaining a proper storage temperature can save you money, reduce waste, and ensure that your paint remains in excellent condition until it’s ready to be used again. Remember these guidelines and tips for preserving paint quality and maximizing your investment.
