Paint should always be stirred before use to ensure that the colour is evenly distributed throughout the paint. This is because the resin and pigments settle towards the bottom while the solvent rises to the top. Paint should be stirred after sitting for more than 24 hours, and if there are any colour differences. While it is possible to shake paint at home, it is difficult due to the weight of the paint. Therefore, it is recommended to use a drill mixer or to take the paint back to the store to be shaken.

What You'll Learn
Paint separation occurs when paint sits for a long time
The length of time that paint can sit unopened without being reshaken depends on the type of paint and storage conditions. Latex paint, for example, is thick enough that the tint typically does not settle at the bottom, and any clear gel-like acrylic resin that rises to the top can usually be stirred back in easily. On the other hand, cheaper paints may end up with water on top and sludge on the bottom after extended periods of time.
If paint has been sitting for a long time and has separated, it can often be remixed by stirring or shaking it. For paint that has been sitting for a while, a longer stirring time may be needed. Some people recommend using a drill mixer or a paint whip attached to a drill for more efficient mixing. Alternatively, some paint stores may be willing to put old cans of paint in their paint shakers to remix the paint.
It is important to note that over-mixing can be an issue with water-borne paints, as they can become foamy and not return to a normal condition. Additionally, rust from the interior of the paint can may mix with the paint if the can has been sitting for a long time, so it is essential to check for this before using the paint.

Stirring or shaking paint recombines separated components
Paint should always be stirred before use, even if it has been shaken at the store. Stirring ensures that any components that have separated during storage are recombined, and that the colour is evenly distributed throughout the paint. This is especially important if the paint has been sitting for more than 24 hours, as separation can start to occur within this time frame.
The process of stirring or shaking paint helps to reincorporate any settled ingredients and ensure a uniform colour and consistency. While some paints may not show visible signs of separation, such as swirls or colour differences, it is still beneficial to stir them before use. This is because separation can start as soon as the paint is no longer moving and can occur at different rates depending on the brand and colour of the paint.
There are various methods for stirring or shaking paint. One common method is to use a drill mixer or paint whip attached to a drill, which can be more efficient and effective than using a traditional stir stick. Another method is to pour the paint into a larger bucket and mix it with a giant mixer or an egg beater attached to a drill, especially for larger quantities of paint. Smaller paint sizes and half-used gallons can also be shaken by hand, although this may be tiring and less effective.
It is important to note that over-mixing water-borne paints can cause them to become foamy, and that varnishes should be stirred gently rather than shaken. Additionally, if the paint is not oil-based, it can be watered down slightly to adjust the consistency.
By stirring or shaking paint before use, you can ensure that the paint is properly mixed and that the colour and consistency are uniform. This will help to achieve the desired results and a high-quality finish when painting.

Shaking paint at home is difficult and ineffective
Shaking paint at home can be challenging and may not always yield effective results. Firstly, it is important to understand that paint needs to be thoroughly mixed for it to be applied evenly and smoothly. While shaking paint by hand may be tempting, it is often insufficient for proper mixing, especially if the paint has been sitting for a long time. Hand shaking may be suitable for a quick remix of an "oily" finish that has floated to the top after a few days of non-use. However, for older paint or paint that has separated, manual shaking is typically inadequate.
One challenge of shaking paint at home is the physical exertion required. Shaking a can of paint by hand can be tiring and may not produce the desired results. It can be difficult to generate enough force to thoroughly mix the paint, especially for larger cans or thicker paints. This can lead to an uneven mixture, with the paint's components remaining separated or clumpy.
Another issue is the potential for messiness. Shaking a can of paint by hand can cause splashing or dripping, resulting in paint wastage and a messy workspace. This is especially true if the paint is thin or runny, as it can easily spill out during the shaking process.
Furthermore, shaking paint at home may not address the root cause of the problem. If the paint has separated due to long-term storage or improper storage conditions, shaking alone may not be enough to restore it to its original consistency. In such cases, stirring with a wooden stick or using a drill attachment can be more effective methods of remixing the paint.
Additionally, some paints may not be suitable for shaking at home due to safety concerns. For example, certain oil-based paints or those in aluminium cans may be flammable, and shaking them could potentially create a hazardous situation. In such cases, it is advisable to seek alternative mixing methods or consult a professional.
Lastly, shaking paint at home can be time-consuming, especially if done manually. Depending on the paint's condition and the desired level of mixing, it may take a significant amount of time and effort to achieve satisfactory results. In contrast, paint stores typically have mechanical shakers that can quickly and effectively mix paint, saving time and ensuring a more consistent finish.

Stirring paint is recommended before use, even if recently shaken
Paint should always be stirred before use, even if it has been recently shaken. Stirring paint ensures that any components that have separated during storage are evenly distributed throughout the paint. This is especially important if the paint has been sitting for more than 24 hours, as separation typically starts to occur within this timeframe.
While it is not necessary to re-shake paint directly before use, stirring it can help to ensure a uniform colour and consistency. Over time, the resin and pigments in the paint will begin to settle towards the bottom, while the solvent will move towards the top. This can result in colour differences and affect the overall quality of the paint.
Stirring paint can be done manually with a wooden stick or a paint whip attached to a drill. For larger quantities of paint, it may be more effective to use a giant mixer designed for mixing paint. It is important to stir the paint thoroughly and ensure that all the way to the bottom of the container is reached.
Additionally, it is recommended to stir paint that has been sitting for a while, even if there are no visible colour swirls. Separation can occur without noticeable changes in the paint's appearance. If the paint has been sitting for months or years, it may be beneficial to have it shaken at a store with a paint shaker.
By following these guidelines and stirring paint before use, even if it has been recently shaken, you can ensure that your paint is properly mixed and ready for application.

Stirring tools like a paint whip, drill mixer, or egg beater can be used
Paint should always be stirred before use to recombine any components that have separated and ensure the colour is evenly distributed. While it is recommended to have paint professionally shaken at the store, this does not replace the need to stir the paint before use. If the paint has been sitting for more than 24 hours, it is beneficial to stir it. If there are visible colour differences, it is important to stir the paint until it returns to a uniform colour and consistency.
Stirring tools can be used to effectively mix the paint. A paint whip, which can be attached to a drill, is a recommended tool for stirring paint. This combination provides a quick and efficient way to mix the paint, as the drill's rotational motion effectively blends the paint's components. Another option is to use a drill mixer, which is specifically designed for mixing paint and other home improvement materials. A drill mixer can be purchased for a relatively low cost, making it an accessible option for paint mixing.
For smaller quantities of paint, such as half a gallon or a pint, an egg beater attached to a drill can be an effective stirring tool. This method is not only fast and efficient but also easy to clean since paint does not adhere to metal. Simply rinsing the beater with water and placing it in the dishwasher is sufficient for cleaning.
Stirring tools, such as a paint whip, drill mixer, or egg beater, offer a convenient and practical way to mix paint that has been sitting. These tools ensure that the paint is thoroughly combined, resulting in a consistent colour and texture for your project.
