Keep Paint Fresh: Tips For Preventing Dried-Out Cans

Keeping paint from drying out in a can is a tricky business, but there are some tried and tested methods to prevent this. From plastic wrap to linseed oil, there are ways to ensure your paint stays fresh. For oil paints, one method is to place your palette under water, cutting off the oxygen supply to the paint. For acrylics, a 'stay-wet palette' can be created using a flat, non-porous container, lined with absorbent material soaked in water, and topped with paper.

Characteristics of keeping paint from drying out in a can

Store in a cool, dry location, out of direct sunlight

Keeping your paint stored in a cool, dry location, out of direct sunlight is a crucial step in ensuring that your paint doesn't dry out in the can.

Firstly, it is important to keep the paint can dry. If the paint can gets wet, it may cause labels to fall off, leaving you unable to identify the paint. A wet paint can may also cause rust, which will not only ruin the can but also the paint inside.

Secondly, the paint should be stored in a cool location. Paint kept at too high a temperature will deteriorate and become unusable. Therefore, it is important to store the paint away from heat sources such as water boilers, radiators, heaters, and direct sunlight.

Thirdly, the paint should be stored in a dry location. This is to prevent moisture from affecting the paint's quality.

Finally, by keeping the paint out of direct sunlight, you avoid the paint becoming too hot, as mentioned above, but also avoid any potential UV damage to the paint.

Overall, by storing your paint in a cool, dry location, out of direct sunlight, you are maintaining the paint's freshness and usability for future projects.

Seal the paint can with plastic wrap

Sealing paint cans with plastic wrap is an effective way to prevent paint from drying out. This method creates an airtight seal, locking in moisture and keeping paint fresh for future use. Here are the steps to follow:

Prepare the Paint Can

Before applying the plastic wrap, ensure the paint can is clean and dry. Any residue or moisture on the can may compromise the airtight seal. Remove any excess paint from the rim of the can to ensure a smooth surface for the plastic wrap to adhere to.

Cut the Plastic Wrap

Take a piece of plastic wrap or plastic from a shopping bag and cut it into a circle slightly larger than the opening of the paint can. The plastic wrap should be large enough to cover the entire opening with some overlap. This overlap is crucial to creating a tight seal.

Apply the Plastic Wrap

Gently stretch the plastic wrap over the opening of the paint can. Ensure the plastic wrap is smooth and free of any tears or punctures. Carefully press the plastic wrap onto the rim of the can, creating a tight seal around the entire edge. Avoid stretching the plastic too tightly, as this may cause it to tear.

Secure the Lid

Once the plastic wrap is securely in place, put the lid back on the paint can. Use a hammer and a block of wood to gently tap the lid into place, avoiding direct hammering on the lid, which may distort its shape and disrupt the seal. Ensure the lid is tightly secured, creating an additional layer of protection against air intrusion.

Storage

Finally, store the sealed paint can in a cool, dry location, away from direct sunlight, and heat sources. Proper storage is crucial to maintaining the freshness of the paint. The ideal storage location should be well-ventilated and consistently maintained at a moderate temperature to prevent the paint from freezing or overheating.

Store paint in an airtight container

To keep paint from drying out, it is essential to store it in an airtight container. This prevents air from entering the container and keeps the paint fresh. Here are some detailed steps to achieve this:

Firstly, choose an appropriate container. Ensure it is made of glass or plastic and is just large enough to hold the paint without leaving excessive airspace. A dry, rust-free container is crucial, as rust can ruin both the paint and the surface it is placed on.

Next, prepare the container to create an airtight seal. Before placing the lid on the container, cover the opening with plastic wrap or plastic from a shopping bag. Stretch the plastic slightly to ensure a tight seal, but be careful not to tear it, as this will compromise its effectiveness.

Additionally, consider using a hammer and a block of wood to gently secure the lid, being cautious not to distort the container's shape, which could disrupt the airtight seal.

For added convenience, you can also note the paint's details, such as the colour, when and where it was used, and where it was purchased, directly on the container. This helps with future paint purchases and ensures you know exactly what paint you have stored.

Finally, store the airtight container in a cool, dry location, away from heat sources and direct sunlight. Maintaining a stable temperature is essential, as freezing temperatures can render paint unusable, while excessive heat will cause it to deteriorate.

Place the paint can in the refrigerator

Keeping paint fresh and preventing it from drying out is a common problem for painters. One solution is to place the paint can in the refrigerator. This method is particularly useful if you are going to be away from your project for a couple of weeks and want to keep your palette colours fresh.

The refrigerator is a suitable place to store paint because it is a cool, dry location, out of direct sunlight. Paint kept at too high a temperature will deteriorate and become unusable. Therefore, it is important to store paint away from heat sources, such as water boilers, radiators, heaters, or direct sunlight.

When placing the paint can in the refrigerator, ensure that the can is sealed correctly and that the paint is stored in an airtight container. This will prevent air from entering the can and keep the paint fresh.

It is also important to note that the refrigerator should not be too cold, as paint can freeze and become unusable. Therefore, it is crucial to maintain a suitable temperature in the refrigerator to ensure the paint remains in a usable state.

Use a 'stay-wet palette'

Using a stay-wet palette is a great way to keep your paint from drying out. This method involves using a flat, non-porous container with low sides, lined with absorbent material soaked in water, and topped with paper. This setup allows a small amount of moisture to penetrate, keeping your paint wet.

To create your own stay-wet palette, start by placing two to three layers of paper towels in your chosen container and saturating them with water. Pour off any excess water, and then top the paper towels with parchment paper cut to size. It's important to ensure that the parchment paper remains dry. Now you can place your paints on top of the parchment paper as you would with any palette.

It's a good idea to change the paper towels every so often, as they can start to smell and even get mouldy over time. You can also cover the tray to keep the paint fresh for longer, although this may not be necessary if you plan to use the paint within a day or two.

Another variation of this method involves using a small rectangular lid from a gelato container as the base of your palette. This can be especially useful if you're working in a remote area or travelling and don't have access to a store-bought stay-wet palette.

Remember to always store your paint in a cool, dry location, away from direct sunlight, to prevent it from drying out or becoming unusable.
