If you’re a DIY, craft, or street artist, you know how important it is to keep your spray paint in good condition for optimal quality and longevity. But how exactly do you store it for the long haul without sacrificing performance? Have no fear, we have all the answers you need! Here’s a comprehensive guide on how to store spray paint for maximum longevity and quality to ensure you can use and reuse your beloved cans time and time again.

Quick Summary of Key Question

Spray paint cans should be stored away from extreme temperatures and in a cool, dry place. To ensure optimal use, it is also important to shake the can prior to use and keep it upright while spraying.

Ideal Storage Environment for Spray Paint Cans

When it comes to storing spray paint cans, the ideal storage environment can make a big difference. It is important that the location chosen is not too warm or not too cold; rather, maintaining an area of consistent mild temperatures—ideally no more than 80°F (27°C)—is best for achieving maximum longevity and quality from spray paint products. Exposure to strong air can cause problems with corrosion and rust on the inside of the cans and could potentially contaminate the contents. Cans stored in areas with excessive moisture can also lead to a diminished shelf life and should be avoided entirely.

Where you decide to store your spray paint cans is just as important as how you store them. It is best to set up your storage space in a well-ventilated area that is sheltered from direct sunlight; this will help keep the temperature stable. This location should also be away from any high-traffic walkways or places where your cans could be accidently knocked over or kicked.

On either side of the argument, there are benefits and detriments when it comes to properly storing spray paint cans. On one hand, lower temperatures help reduce the evaporation rate of any solvents contained within the can while reducing their exposure to oxygen, both key factors to keeping them fresh and useable over time. In addition, cooler temperatures may help prevent moisture accumulation, further avoiding issues like rust, oxidation, peeling labels, and other types of damage. On the other hand, higher temperatures can sometimes result in more efficient drying times for some paints and may help avoid clogging between uses, yet consistently warm temperatures are still considered among experts too risky for maximizing product shelf life.

In conclusion, understanding and controlling your storage environment is essential for ensuring that your spray paint cans last as long as possible with reliable quality results. For this reason, choosing an area that adheres to proper temperature guidelines and offers a safe place from most hazards is preferred by most hobbyists and professionals alike. As we turn our attention to appropriate room temperatures for successfully storing spray paint products, we must consider two main principles: temperature stability and adequate ventilation for dryness control.

  • According to the Spray Paint Manufacturers Association, spray paint should be stored at temperatures between 50 and 77 degrees Fahrenheit, with a relative humidity of 65% or less.
  • The U.S. Environmental Protection Agency recommends storing aerosol cans in cool, dry places away from potential sources of fire and heat.
  • According to the National Paint and Coatings Association, spray paint should remain tightly sealed when not in use and be kept out of direct sunlight.

Appropriate Room Temperature

When it comes to storing spray paint for maximum longevity and quality, it is important to consider the room temperature in which the cans of paint are being stored. While some people may argue that storing spray colors at cooler temperatures will help maintain their performance, this may not be the case. Many experts say that the best temperature range for storing spray cans is between 65-85 degrees Fahrenheit. This temp range helps preserve the propellant in the can, with lower temperatures resulting in a can that takes too much pressure to use and warmer temps not allowing enough air pressure. Ideally, it is best to store paints indoors, as extreme heats and cold can negatively affect the performance of the paint.

It is also important to avoid placing cans of paint near heat sources or anywhere where extreme temperature changes are expected (e.g. near open windows or vents). Allowing cans of spray paint to become too hot may lead to a decrease in quality or intially make the can appear clumped up due to condensation buildup on the outside – even if stored properly in its original package – so it is best to keep them away from high-heat areas like attics or garages.


In conclusion, it is very important to store spray paint cans at the correct room temperature in order for them to work at their full potential and last longer. By finding an area within the recommended temperature range of 65-85 degrees Fahrenheit and avoiding areas with extremes in temperature change or heat, you can ensure your cans of spray paint will remain at optimal performance for as long as possible. In our next section we will discuss how humidity levels effect spray paint as well as how to ensure they stay within appropriate levels for maximum longevity and quality.

Appropriate Humidity Levels

The humidity level in the surrounding environment where spray paint is stored also has a major impact on its shelf-life and quality. In general, storing of spray paint cans in areas with relatively low levels of moisture is essential for a long-term and effective outcome. This means that the ideal relative humidity for storing spray paint should not exceed 50%-55%, as higher levels might corrode and rust parts of the cans.

In some cases, business owners might not be able to maintain humidity levels below the suggested range due to their geographic location or other conditions. While it is not possible to maintain adequate storage conditions in such cases, by minimizing moisture content as much as possible, users can still improve the shelf life of their spray paint cans. In addition, ensuring cans remain unopened until use will also prevent mold build up inside them over time.

These points suggest that maintaining an optimal level of relative humidity between 50%-55% is ideal for spray paint storage, however if this cannot be achieved, having lower levels of humidity to minimize moisture exposure can help improve storage times significantly. To move onto the next step in maximizing the longevity and quality of your stored spray paint cans, our next section will discuss appropriate containers for them.

Storage Containers for Spray Paint Cans

When it comes to storing spray paint cans, many people assume that any container will do. However, the truth is that there are distinct differences between containers when it comes to the long-term storage of spray paint colors. It is essential to pay close attention to the types of options available and determine which one is the most suitable for each particular situation.

For starters, the most important factor in choosing a storage container for spray paint cans is making sure that it is secure and able to be sealed properly in order to protect the contents from environmental elements such as moisture, dust, and other debris. Some people may opt for cardboard boxes with lids or plastic storage bins as they are often lightweight, relatively inexpensive, and easily found at local stores. The primary downside of using these containers is that they do not create an airtight seal, potentially allowing moisture and airborne particles to come in contact with the can interiors and cause damage.

On the other hand, rigid storage containers made from hard materials such as plastic or metal can provide better protection against outside elements while still being reasonably affordable. These containers also typically feature locking lids or clasps which result in a more secure closure and an airtight seal to keep out unwanted particles. However, these containers can be slightly heavier and less mobile than their softer counterparts and sometimes require additional equipment such as screws or tools to keep them sealed shut.

At the end of the day, whether it be a cardboard box or a hard plastic container, all potential storage vessels should be evaluated based on their ability to remain secure and protect the contents from external factors. Leading into the next section about “Using Airtight Plastic Containers” helps ensure exactly this kind of protection and longevity for priceless spray paint projects.

Use Airtight Plastic Containers

One of the most effective ways to store spray paint to maximize longevity and quality is in airtight plastic containers. The tight seal that containers like Tupperware® provide helps prevent outside contaminants from getting in, which can significantly reduce the success of your project. Additionally, plastic containers prevent light from entering and discoloring paint properties.

As with any material, there are cons to consider when using plastic containers. First, if the seals are not applied properly, then you run the risk of an undesirable spill, or worse; a reaction between the spray paint fumes and oxygen within the container that could cause an explosion or fire hazard. Make sure the seal is secure before storing in a tightly packed closet, garage, or workspace. Second, since air cannot enter, condensation is more likely to occur than with cardboard boxes and other storage solutions. This can also lead to discoloration and other undesirable effects on the integrity of your stored paints.

Finally, plastic should be considered a temporary rather than long-term storage solution as they disintegrate over time due to naturally occurring environmental elements. When planning for long-term storage needs, look into alternatives that provide the same benefits listed above but with greater longevity overall.

For these reasons and more, it is important to keep safety in mind first when deciding whether or not to use a plastic container for storing spray paint. Even though there may be some risks associated with their use, done correctly airtight plastic containers can be beneficial in managing and preserving your stash for future projects.

Having established the benefits of using proper airtight plastic containers for storing spray paint comes with certain responsibilities and considerations for maintaining quality control. To help ensure maximum viability for all products stored in this way for longer periods of time, it is important to avoid using cardboard boxes—the next section will discuss why this storage solution should be strictly avoided when planning paint preservation projects.

Avoid Using Cardboard Boxes

The best way to store spray paint for maximum longevity and quality is by avoiding using cardboard boxes. Cardboard quickly absorbs moisture, odor, and acidity when exposed to the air, which can damage the paint and its components. In addition, storage in cardboard boxes can also cause rust spots on the top of the cans when exposed to moisture.

Using cardboard boxes for storage may seem like a convenient option due to their low cost and easy availability, however proper storage is essential for longer lasting spray paint. With this in mind, alternate material should be sought out when it comes to storing spray cans in order to ensure the highest quality of product.

When debating both sides of the argument it can be concluded that while cardboard boxes are easily accessible and a low cost solution, non-cardboard material should be utilized when it comes to stocking spray cans in order to ensure their safety as well as their longevity.

The next section will discuss tips for maintaining shelf life of spray paint. It’s important to understand the most effective methods of storing these products so they will last longer and remain viable throughout their duration.

Tips for Maintaining Shelf Life of Spray Paint
