Does Storing Paint Cans Upside Down Actually Work?
If you have ever done a home renovation project, you know the frustration: you finish painting, seal the lid on the paint can, and months later, when you need a touch-up, the paint is dried out or covered with a thick skin. That’s why many DIYers and even some professionals have passed along a popular tip: store paint cans upside down. But does storing paint cans upside down actually work, or is it just another home improvement myth? Let’s dig deeper.
Why Do People Store Paint Upside Down?
The idea behind upside down paint storage is simple: when you flip the can, the liquid paint creates a seal against the lid, blocking air from entering the container. Air is what causes paint to dry out or form a crusty layer, so in theory, this upside down method prevents air leakage and keeps your paint fresh.
This trick has been around for decades, but not everyone agrees that it’s the best solution. To really understand it, we need to explore whether you can store paint cans upside down safely and what professionals recommend.
Can You Store Paint Cans Upside Down Without Problems?
Yes, you can store paint cans upside down, but with some caution. Here are a few things to consider:
- Seal matters most: If the paint lid isn’t hammered down tightly, flipping it can actually cause leaks instead of preserving the paint. A rubber mallet is the best tool to reseal the lid after use.
- Paint type: Latex and water-based paints usually do fine upside down, but oil-based paints are messier and more prone to leaking.
- Storage location: If you’re putting cans on a shelf in your garage or basement, make sure they’re on a stable surface. You don’t want a wobbly upside down can dripping paint.
So, while storage paint cans upside down can be effective, it’s not foolproof. The key factor is how well-sealed your can is in the first place.
Why Store Paint Cans Upside Down?
Here are the main reasons DIYers swear by upside down paint storage:
- Prevents skinning: No more opening the lid to find a thick layer of dried paint floating on top.
- Keeps air out: Creates a more airtight seal compared to storing the can upright.
- Saves money: You won’t need to constantly buy new paint for small touch-ups.
On the flip side, critics argue that if you seal the can correctly, it shouldn’t matter whether it’s stored upright or upside down. This leads us to the bigger question: should paint cans be upside down at all?
Should Paint Cans Be Upside Down or Upright?
While upside down paint storage can help, it’s not the only method for preserving leftover paint. Many professionals believe that how to store paint cans properly matters more than simply flipping them.
Best practices include:
- Storing paint in a cool, dry location (avoid direct sunlight and freezing temps).
- Wiping paint off the rim before sealing, so the lid closes tightly.
- Labeling cans with the paint color, room, and date of use.
- Transferring leftover paint into smaller, airtight containers if the can is less than half full.
This last method is actually one of the most effective. By reducing air space in the container, you naturally extend the shelf life of your paint.
Upside Down Paint Storage: Pros and Cons
To help you decide, here’s a quick breakdown of the benefits and drawbacks:
Pros
- Creates an airtight seal.
- Simple and requires no special tools.
- Can extend paint freshness by months or even years.
Cons
- Risk of leaking if lid isn’t sealed properly.
- Cans become unstable in storage.
- Not recommended for large amounts of paint.
Ultimately, whether paint should be upside down depends on your storage environment and how much leftover paint you’re trying to preserve.
Alternatives to Storing Paint Cans Upside Down
If you don’t want to risk spills or messy shelves, here are safer alternatives:
- Plastic Wrap Trick: Place plastic wrap directly on the surface of the paint before sealing the lid. This prevents a skin from forming.
- Vacuum Seal Containers: Transfer paint into airtight plastic containers or mason jars.
- Upside Down in a Bag: If you still want to flip the can, put it inside a sealed plastic bag first.
These methods often work just as wel, or bette, than simply flipping a paint can.
Can You Store Paint Upside Down Long Term?
For long-term storage, flipping a can upside down isn’t the best solution. Over time, paint can separate, and storing it upside down makes it harder to remix when you need it again. Plus, if you ever stored paint for years, you probably know that stirring is essential before reusing.
If you need paint to last for multiple years:
- Keep cans in climate-controlled spaces.
- Avoid extreme heat or freezing.
- Check paint consistency before reusing.
In some cases, old paint may no longer be usable, even if you stored it carefully. That’s why proper methods matter more than tricks.
Expert Tips: How to Store Paint Cans Properly
Here’s a step-by-step method to maximize your leftover paint’s life:
- Clean the rim and lid of the can after use.
- Place plastic wrap over the opening.
- Seal the lid tightly with a mallet (not a hammer).
- Label the can with color and date.
- Store cans in a dry, cool location off the floor.
This is the method many pros prefer instead of depending solely on upside down paint storage.

(Final Verdict) Does Storing Paint Cans Upside Down Actually Work?
So, does storing paint cans upside down actually work? The answer is yes, but with conditions. It can help keep air out and paint fresh, but only if the lid is sealed tightly and the can is stored in a stable, climate-controlled place.
If you’re storing a nearly full can for a few months, flipping it may extend freshness. But for long-term storage or half-empty cans, consider alternatives like transferring paint to airtight containers.
At the end of the day, proper storage methods outweigh quick hacks. Whether you flip the can or not, always focus on sealing, labeling, and storing paint in the right environment.
