When it comes to preparing paint for your next project, you may have wondered whether it’s better to stir or shake the paint can.

While both methods aim to mix the paint thoroughly, there are important differences between stirring and shaking that can affect the quality of your paint job.

In this article, we will explore the pros and cons of each method, how to stir paint effectively, and whether certain types of paint require shaking or stirring.

Understanding the Importance of Stirring Paint

Stirring paint is a crucial step in the painting process as it ensures that the pigments, binders, and solvents are evenly distributed.

Over time, paint can settle, with heavier components sinking to the bottom of the can.

By stirring the paint, you reintegrate these components, resulting in a consistent color and texture throughout your project.

Neglecting to stir paint properly can lead to uneven application, color variations, and compromised durability.

Stirring vs Shaking: What’s the Difference?

The main difference between stirring and shaking paint lies in the motion used to mix the contents.

When you stir paint, you use a stirring stick or tool to manually agitate the paint in a circular motion.

This method allows for controlled mixing and is ideal for paints that have been sitting for a while or have separated significantly.

On the other hand, shaking paint involves vigorously shaking the paint can to mix the contents.

This method is more convenient and requires less effort, making it a popular choice for quick touch-ups or small projects.

However, shaking can introduce air bubbles into the paint, which may affect the final finish and adhesion.

The choice between stirring and shaking depends on the type of paint, the condition of the paint can, and the desired consistency.

In general, stirring is recommended for most paint types, while shaking can be suitable for certain situations.

How to Stir Paint Properly

To stir paint effectively, you will need a few tools and follow a step-by-step process. Here’s a guide to help you stir paint like a pro:

  1. Gather the necessary tools: You will need a clean stirring stick or paddle, a paint can opener, and a clean container to pour the paint into if necessary.
  2. Prepare the paint can: Use a paint can opener to remove the lid. If the paint has been sitting for a while, you may notice a layer of dried paint on top. Gently scrape off this layer before stirring.
  3. Start stirring: Insert the stirring stick into the paint can, making sure it reaches the bottom. Begin stirring in a circular motion, gradually working your way from the bottom to the top. Continue stirring for several minutes to ensure thorough mixing.
  4. Check the consistency: As you stir, pay attention to the paint’s consistency. If it feels too thick or lumpy, continue stirring until it becomes smooth and uniform. If necessary, add a small amount of paint thinner or water to achieve the desired consistency.
  5. Pour and strain if needed: If you prefer to pour the paint into a separate container for easier access, do so carefully. Additionally, if you notice any lumps or debris in the paint, strain it through a mesh strainer or cheesecloth before use.

By following these steps, you can ensure that your paint is properly mixed and ready for application.

Does Home Depot Shake Paint for Free?

Home Depot is a popular destination for purchasing paint and other home improvement supplies. Many customers wonder whether Home Depot offers free paint shaking services.

While policies may vary depending on the location, Home Depot generally provides free paint shaking services to its customers.

To take advantage of this service, simply bring your paint can to the paint department and ask a store associate for assistance.

They will use a paint shaker machine to thoroughly mix the paint for you.

Keep in mind that there may be limitations on the size and type of paint cans that can be shaken, so it’s always best to check with your local Home Depot store beforehand.

Some hardware stores, paint supply stores, or rental centers may offer paint shaking services for a fee.

Additionally, you can invest in a paint shaker machine or use manual shaking techniques at home, which we will discuss further in the next section.

Stirring Paint with a Drill: Pros and Cons

For larger paint projects or when dealing with particularly stubborn paint that requires thorough mixing, using a drill with a paint mixing attachment can be a time-saving option.

Here are the pros and cons of using a drill for stirring paint:


  • Efficiency: Using a drill with a paint mixing attachment can significantly reduce the time and effort required to stir paint, especially for larger quantities.
  • Thorough mixing: The high-speed rotation of the drill ensures that the paint is mixed uniformly, eliminating any lumps or inconsistencies.
  • Versatility: A drill can be used for various paint types, including latex, oil-based, and even thicker materials like joint compound or texture mix.


  • Potential mess: The high-speed rotation of the drill can cause paint splatter, so it’s essential to take precautions by wearing protective clothing and covering the surrounding area.
  • Limited control: Unlike manual stirring, using a drill offers less control over the mixing process. It’s important to monitor the paint’s consistency closely to avoid overmixing or introducing air bubbles.

To use a drill for stirring paint, attach a paint mixing paddle to the drill chuck. Insert the paddle into the paint can and turn on the drill at a low speed to prevent splattering.

Gradually increase the speed while moving the paddle in a circular motion to mix the paint thoroughly.

Be sure to follow the manufacturer’s instructions for both the drill and the paint mixing attachment.

How Long Will Paint Stay Mixed After Shaking?

After shaking paint, you may wonder how long it will stay mixed before it needs to be stirred again.

The answer depends on several factors, including the type of paint, the quality of the mixing, and storage conditions.

In general, properly mixed paint can stay usable for several hours to several days.

Latex or water-based paints tend to have a shorter shelf life after shaking compared to oil-based paints.

Latex paints can typically stay mixed for up to 48 hours, while oil-based paints can last for several days or even weeks.

However, it’s important to note that these timeframes are approximate, and the paint’s condition should be assessed visually and by performing a stir test before use.

Factors such as temperature, humidity, and exposure to air can affect the longevity of mixed paint.

Higher temperatures and excessive air exposure can cause the paint to dry out or form a skin on the surface, making it necessary to stir the paint again before use.

It’s always a good idea to check the paint’s consistency and perform a stir test if you’re unsure about its usability.

Does Primer Need to be Shaken or Stirred?

Just like paint, primer also requires proper mixing to ensure optimal performance. However, the method of mixing primer may differ depending on the type of primer you are using.

Oil-based primers typically need to be shaken before use. Shaking helps to disperse any settled pigments and ensures a consistent color throughout the primer.

It’s important to shake the can vigorously for a few minutes to achieve thorough mixing.

On the other hand, latex or water-based primers are best stirred. Stirring latex primer helps to incorporate any separated components and achieve a smooth, uniform consistency.

Use a stirring stick or paddle to mix the primer in a circular motion, similar to stirring paint.

Always refer to the manufacturer’s instructions on the primer can for specific guidelines on mixing and application.

Following these guidelines will help you achieve the best results and ensure that the primer performs as intended.

How Long to Stir Paint: A Comprehensive Guide

The duration of paint stirring depends on various factors, including the type of paint, the size of the container, and the condition of the paint.

While there is no fixed time for stirring paint, here are some general guidelines:

  • Small containers: For small paint cans or containers, stirring for 1-2 minutes is usually sufficient. However, if the paint has been sitting for a while or appears separated, you may need to stir for a bit longer to ensure thorough mixing.
  • Large containers: When dealing with larger paint cans or buckets, it’s recommended to stir for at least 3-5 minutes. The larger volume of paint requires more time to achieve uniform consistency.
  • Thick or heavy-bodied paints: Paints with thicker or heavier consistencies, such as textured paints or some oil-based paints, may require additional stirring time. Aim for 5-10 minutes of stirring to ensure proper mixing.
  • Stirring intervals: If you’re working with a large quantity of paint or taking breaks during your project, it’s a good practice to stir the paint intermittently to prevent settling. Stir every 30 minutes to an hour to maintain consistency.

Remember, these are general guidelines, and the actual stirring time may vary depending on the specific paint brand and type.

Always refer to the manufacturer’s instructions for recommended stirring times.

How to Stir Paint Without a Stick

If you find yourself without a stirring stick or prefer not to use one, there are alternative methods for stirring paint. Here are a few options:

  1. Use a clean wooden dowel or disposable chopstick: If you don’t have a dedicated stirring stick, a clean wooden dowel or disposable chopstick can serve as a makeshift alternative. Make sure it is clean and free from any contaminants before using it to stir the paint.
  2. Utilize a clean plastic spoon or spatula: In a pinch, a clean plastic spoon or spatula can be used to stir paint. These utensils are readily available in most kitchens and can be easily cleaned before and after use.
  3. Repurpose a plastic bottle or container: Cut off the bottom of a clean plastic bottle or container to create a makeshift stirring tool. The open end can be used to stir the paint effectively.

While these alternatives may not provide the same level of control as a dedicated stirring stick, they can still help you achieve a reasonably well-mixed paint.

Remember to clean and dry these makeshift tools thoroughly before using them to avoid introducing any foreign substances into the paint.

How to Shake Paint at Home

Shaking paint cans at home can be a convenient option, especially if you don’t have access to a stirring stick or paddle. Here’s a step-by-step guide on how to shake paint cans effectively:

  1. Ensure that the paint can is securely closed and that the lid is properly sealed.
  2. Hold the paint can firmly with both hands, ensuring a tight grip.
  3. Shake the can vigorously in an up-and-down motion for several minutes.
  4. Rotate the can while shaking to ensure that all areas are adequately mixed.
  5. Periodically stop shaking and listen for any sloshing sounds, indicating that the paint is well-mixed.
  6. After shaking, allow the paint to settle for a few minutes before opening the can to avoid any splattering.

While shaking paint can be a quick and convenient method, it’s important to note that it may introduce air bubbles into the paint.

If possible, allow the paint to sit for a while after shaking to allow any air bubbles to rise to the surface. This will help ensure a smoother application and finish.
