Some hardware stores may refuse to shake old paint that wasn't bought there

Paint that has been sitting for a while will start to separate, and it is recommended to stir or shake it before use. While some hardware stores offer to shake old paint for free, others may refuse to do so, especially if the paint was not bought there.

Some stores have a policy of only shaking paint that was purchased from them. This may be due to the potential risks involved in shaking old paint. For example, if the paint can is old and rusty, it could spring a leak while being shaken, creating a mess and wasting paint. Additionally, some types of paint are flammable and cannot be shaken.

In some cases, hardware stores may be willing to shake old paint that was not purchased there, but they may charge a fee for the service. It is always a good idea to ask politely and be prepared to purchase a small item from the store.

It is worth noting that shaking old paint may not always be effective. In some cases, the paint may dry weirdly or peel, requiring additional work to scrape, sand, and repaint. Therefore, it is recommended to dispose of old paint properly and purchase new paint when needed.

Overall, while some hardware stores may refuse to shake old paint that was not bought there, it is worth asking politely as policies may vary. However, it is important to be aware of the potential risks and limitations of shaking old paint.

Shaking old paint may not restore it to its original state

If the paint is still in good condition, it may be possible to restore it by shaking. However, this is not always effective. One user reported that their 10-year-old paint looked fine after mixing and applying, but it dried weirdly and peeled off. Another user reported that their old paint looked good after shaking, but the colours had started to separate out.

To determine whether old paint is still usable, it is recommended to smell it first. If it smells bad, mouldy, or weird, it should be thrown away. It is also important to check the paint can for any signs of rust or blobby junk on top. If the paint is still clean, it can be mixed and used.

Some hardware stores offer paint-shaking services, but this is usually only for paint that has been purchased from them. It is worth asking the store politely if they can shake your old paint, but be aware that they may refuse due to safety concerns or because the paint is not theirs. Some stores may also charge a fee for this service.

If you cannot get your old paint shaken at a hardware store, you can try shaking it yourself by hand or using a drill attachment. However, shaking by hand may not be effective for paint that has been sitting for longer than a few days, as it can be difficult to mix the paint evenly. A drill attachment or a paint mixer on a drill can be more effective for mixing old paint.

Paint that has separated may not need to be shaken

If the paint has separated, it is recommended to stir it for a couple of minutes before painting. The time needed to stir the paint depends on its appearance. For instance, if the colour looks close to what it should be, a couple of minutes of stirring should suffice. However, if the paint has separated a lot, it may need to be stirred for about five minutes. If there is a clear coat on top of the paint, a couple of light stirs may be sufficient.

In some cases, hand shaking can be used as an alternative to stirring. However, this may not adequately mix the chemicals that have sunk to the bottom of the can. Therefore, it is generally recommended to have the paint professionally shaken initially and then stir or hand shake it before use.

Additionally, the type of paint can impact the mixing process. For instance, water-borne paints can become foamy if over-mixed. On the other hand, cheaper acrylic resins and pigments tend to separate more quickly and may require re-stirring after a week or more.

It is worth noting that some paints, such as latex paint, are thick enough that the tint does not fall to the bottom. In such cases, a clear gel-like acrylic resin may rise to the top over time, but it usually stirs back in easily.

Paint cans should not be shaken upside down

Many hardware stores offer to shake paint cans for their customers, especially if the paint was purchased from their store. However, it is not advisable to shake paint cans upside down.

Shaking a paint can upside down can cause the lid to spring a leak, resulting in a mess. The pressure of the paint inside the can when shaken upside down can cause the lid to pop off, leading to a spill. The bottom of paint cans is usually thin and susceptible to rusting, which further increases the likelihood of leakage.

Additionally, if the paint can is stored upside down, the lid can get stuck to the surface it is placed on. When the can is then lifted, the lid may come off, leaving behind a mess.

To prevent this, it is recommended to store paint cans right-side up and ensure the lid is securely fastened. Other methods to maintain the paint's freshness include using plastic wrap, anti-skinning sprays, plastic rings, or displacing oxygen by spraying argon gas into the can before sealing.

While shaking paint cans upside down is not advisable, it is important to note that hardware stores may have their own policies regarding shaking paint that was not purchased from their store. Some stores may refuse to shake paint that customers bring in due to the potential risks mentioned above.

Some paints are flammable and cannot be shaken in-store

Most hardware stores will shake paint for you if you ask politely, even if it wasn't bought there. However, some paints are flammable and cannot be shaken in-store. Oil-based paints are considered flammable, and some water-based paints may also be dangerous. Manufacturers supply Safety Data Sheets (SDS) for all chemicals they sell, which include important information for safe usage, handling, and storage.

When storing flammable paint in the workplace, it is important to conduct a risk assessment and adhere to the control measures outlined in the ACOP HSG51 to reduce the risk of harm to human health and financial liability due to non-compliance. The primary control measure to prevent the release of flammable vapours into the workplace is the paint container. The construction requirements for flammable paint containers include using materials compatible with the chemical properties of the paint and fitting the container with a well-equipped cap.

Additionally, to reduce the risk of fires, flammable paints must be stored in well-ventilated areas to prevent the accumulation of flammable vapours. An uncongested, unenclosed outdoor area is ideal, as it allows flammable vapours to easily disperse. If outdoor storage is not possible, indoor storage in a compliant flammable storage cabinet is recommended. It is also crucial to ensure that all paint cans and containers are properly sealed before storage to prevent the build-up of flammable vapours.

It is worth noting that shaking old paint may not always yield desirable results. Even after mixing, old paint may dry weirdly and peel, requiring additional work for scraping, sanding, and repainting. Therefore, it is advisable to ask the hardware store about any charges for shaking paint and assess whether the paint is still usable before proceeding.
