However, the biggest challenge is storing the paint without having it go bad or drying. The good news is that there are many plastic containers you can use to store excess paint.
Whether oil-based or water-based, plastic containers are quite effective at storing paints. However, you need to choose the right type of plastic container. Some paints can break and degrade plastic containers.
Oil-based paints can last up to 15 years when left unopened. However, once youve opened and used them, the excess must be kept in airtight containers.
If you seal the paint properly in plastic containers, it can last for up to 7 years. However, its recommended that you use them within 2-3 years for the best results.
Apart from choosing the right plastic container, you need to store the paints in cool and dry areas. Keeping the paint away from direct sunlight extends its shelf life.
What Type Of Container Can I Store Paint In?
So, whats the best container for storing paint? The best and recommended containers are those made of HDPE and PET materials. High-density polyethylene and polyethylene terephthalate are ideal and offer the best results.
In fact, plastic containers are so effective and reliable. Some paint brands are even replacing paint cans with plastic containers.
In addition, you can use heavy-duty Tupperware type of plastic. Its waterproof and can withstand both oil-based and water-based paints.

However, you need to ensure the jars and containers come with a good opening and an airtight lid. Wide openings allow for easy paint pouring. Airtight lids ensure the paint is protected from air staying fresh for longer.
Now that you know the right container to store paint, let’s see how you can store the paint.
How To Store Paint In Plastic Containers?
Taking the right steps to store the leftover paint will ensure it stays fresh for longer. Here are ways you can store paint in plastic containers.
First, you need to get a clean plastic container with an airtight seal. You need a container that will hold the paint without leaving too much air space inside.
Depending on the amount of paint left, you can choose a matching container. For example, small amounts of paint can be stored in small plastic jars with lids.
Start by washing the container and clearing all the dirt inside. Once the container is clean, make sure the lid is securely tight and prevent air leakages.
If the paint is exposed to air, it will likely go bad. Once youre sure the container will close tightly, transfer the leftover paint inside. If the opening is small, consider using a funnel to prevent paint from spilling.
Make sure you fill the container without leaving too much air space. This is why I recommended choosing a container that will fit the leftover paint. Overall, the paint should fill most of the container. You dont want to leave too much air space inside.
With the paint settled inside, use a plastic wrap and create an airtight seal around the lid. You want to make sure there is no air getting in and out. You can do this by spreading a piece of plastic paper over the opening before placing the lid.
Alternatively, you can use a plastic shopping bag to create an airtight seal. This is done by cutting a plastic shopping bag in the shape of the opening. The bag should be slightly larger than the opening. Place it on top of the opening and then close the lid.
Make sure you close the lid gently to avoid breaking the plastic bag. You want to make sure the seal is airtight.
Is the container transparent? If not, then you need to label it. On the label, note the color of the paint and where you bought it. This is necessary should you need more paint in the future.
Lastly, you need to choose a proper location to store the paint. Select a cool and dry place away from direct sunlight. Make sure the location has average temperatures that prevent the paint from overheating or freezing. Frozen paint separates and becomes permanently unusable.
Oil-based paints are not safe to store in homes. If you store them poorly, they can emit fumes or become a flammable posing danger to your family.
You can place the container in a damp-free area in your garage or basement.
