Preventing Paint Moisture: Sealing And Storing Tips

Keeping moisture out of paint containers is essential to prevent paint from spoiling. Moisture can cause rust, which can contaminate the paint and make it unusable. To keep paint containers dry, it is recommended to store them in a cool, dry place, away from direct sunlight, and to ensure that the containers are sealed tightly to prevent moisture ingress. Using airtight containers, such as glass jars or lidded mason jars, can help to keep moisture out and prolong the life of the paint. Additionally, inert gas preservatives can be used to purge excess moisture from containers, especially for oil-based paints that may be stored for long periods. Proper labelling and dating of paint containers can also help to ensure the right paint is used for the right project, reducing the chance of moisture ingress from frequent opening and closing.

Use airtight containers

To keep moisture out of your paint containers, it is essential to use airtight containers. This will help prevent moisture from seeping in and ruining your paint. Here are some tips to ensure your paint is stored correctly and securely:

Firstly, choose the right type of container. Airtight glass jars or lidded mason jars are excellent options for storing paint for extended periods. Glass containers offer the advantage of being eco-friendly and reusable. However, it is crucial to store them in a cool, dark place, as light exposure can negatively impact the paint. As you use up the paint, remember to downsize to a smaller container to minimise air exposure.

When using glass containers, ensure that the lids are secure and create an airtight seal. Avoid using dull paint can openers, as they can create an uneven connection around the rim, preventing an airtight seal. Instead, use a rubber mallet to tap the lid securely shut. If you don't have a mallet, cover the container with a piece of wood and then gently hammer the lid closed.

Additionally, consider using plastic wrap to enhance the seal. Cover the opening of the container with plastic wrap before putting on the lid. This creates a tighter seal, further protecting your paint from moisture. If you're using the original paint can, a rubber band strapped around the top can also help keep air out.

Properly labelling your airtight containers is also essential. Use a permanent marker to indicate the brand, paint name, date of purchase, mixture number, and the room or wall painted. You can also place a small amount of paint on the exterior of the container to easily identify the colour. Proper labelling ensures you don't have to open each container to verify its contents.

By following these tips and using airtight containers, you can effectively keep moisture out of your paint and extend its lifetime. Remember to regularly check your paint for any signs of spoilage, such as foul odour or mould, and always store it in a cool, dry, and dark location.

Store in a cool, dark place

To keep paint moisture out of its containers, it is essential to store it in a cool, dark place. Here are some detailed instructions to achieve this:

Firstly, choose an appropriate storage location that meets the criteria of being cool and dark. An ideal spot could be a basement, provided you keep the paint cans on a shelf, as moisture from basement floors can cause rust. If you don't have access to a basement, a cabinet or closet in your house can serve as a suitable alternative. The key is to select a place that maintains a consistent temperature and is shielded from direct sunlight.

For those with a climate-controlled basement or garage, these spaces can be viable options for storing paint. Just be mindful of temperature fluctuations, especially if you live in an area with extreme weather conditions. Keeping the paint in its original container with the lid tightly secured is crucial to preventing moisture ingress.

If you're using a different container, opt for airtight glass jars or lidded mason jars. These containers offer the advantage of being eco-friendly and reusable. However, they require extra caution to avoid light exposure, as prolonged exposure to light can negatively affect the paint.

As you use up the paint, downsize to a smaller container to limit air exposure. This practice helps maintain the quality of the remaining paint. Additionally, clearly label your paint containers with essential information, such as the brand, paint name, date of purchase, mixture number, and the room or surface it was used on.

By following these instructions and storing your paint in a cool, dark place, you can effectively minimise moisture issues and prolong the lifespan of your paint.

Avoid moisture from basement floors

Keeping paint in airtight containers and storing it in a dry place is essential to prevent moisture buildup and rust formation. Using inert gas preservatives can also help to prevent moisture buildup in paint containers.

Now, let's discuss how to avoid moisture from basement floors:

Basements are prone to moisture issues due to their location and the surrounding environment. Here are some ways to address and prevent moisture from seeping into your basement floors:

• External Waterproofing: This involves digging down to the foundation footer and adding a drainage system and a waterproof membrane to the exterior of the foundation. It is considered the best way to fix moisture issues.
• Internal Drainage System: If external waterproofing is not an option, an alternative method is to cut a channel along the walls to allow water to flow into a crock in the basement, where a sump pump can be installed. While this doesn't address the root cause of water seepage, it helps manage the water that enters the basement.
• Grading and Gutters: Ensure that the ground around your house is graded correctly, sloping away from the foundation wall. This prevents rainwater from being directed towards the basement. Install and maintain gutters and downspouts to direct rainwater away from the building's perimeter.
• Sub-Surface Drainage System: If you don't already have one, consider installing a sub-surface drainage system. This involves digging up the basement floor to set up a drainage system that expels moisture through a pump.
• Address Internal Moisture Sources: Moisture can also be generated inside the basement from activities such as showering, cooking, and using unvented clothes dryers. Ensure proper ventilation in your basement, especially when performing moisture-generating activities.
• Pipe Insulation: Wrap water pipes with insulation foam to reduce condensation dripping onto basement floors, which can encourage the growth of mold and mildew.

By implementing these measures, you can effectively avoid moisture from basement floors and maintain a dry and healthy basement environment.

Use inert gas preservers

Using inert gas preservers is an effective way to keep paint moisture out of its containers. One such preserver is Bloxygen, which uses 100% natural Argon, a heavy and inert gas, to form a protective barrier over the paint. This barrier prevents oxygen and moisture damage, which can cause hardening, separation, and spoilage.

To use Bloxygen, simply spray a small amount into the paint can and close the lid. It is compatible with every finish and can be used to preserve oil-based paints, varnishes, polyurethanes, and other coatings. It is also food-safe and can be used to preserve coffee beans, wine, cooking oils, and other perishables.

Inert gas preservers are especially useful for storing costly paints and coatings that may be kept for long periods between uses. They can extend the shelf life of these products by up to 10 years, ensuring that you get to use all of your paint without waste.

Additionally, inert gas preservers can help cut down on hazardous disposal. By preventing paint from spoiling, they reduce the need for disposal of crusty, unusable paint, which can be harmful to the environment.

Overall, using an inert gas preserver is a simple and effective way to keep paint moisture out of its containers, preserving the quality and longevity of your paint products.

Label paint containers

Properly labelling paint containers is essential for keeping track of your paint inventory and ensuring the paint's longevity. Here are some detailed instructions for labelling paint containers:

Label the Paint Type and Colour

Clearly label the paint container with the type and colour of the paint. You can use a permanent marker or a label maker to write down the specific shade, brand, and product name. This information is crucial, especially if you need to purchase more paint for touch-ups or future projects.

Include the Date of Purchase and Mixture Information

Note down the date when you bought the paint, as paint typically has a shelf life. For example, water-based paint usually lasts up to 10 years, while most paint products have a shelf life of 2 years. Additionally, if the paint has been mixed, include the mixture number or any other relevant details.

Specify the Room or Surface Painted

It is helpful to label the room or surface where the paint has been used. This information can be useful for future reference, especially if you need to touch up specific areas or want to ensure consistent paint finishes throughout your home.

Mark the Paint Level and Sheen/Finish

Indicate the level of paint in the container by painting a line on the exterior of the can with the same paint. This provides a visual representation of the paint colour and its quantity. Additionally, make note of the sheen or finish of the paint, such as high-gloss or matte, so you know what to expect when using the paint again.

Store in a Cool, Dry Place

Always store your labelled paint containers in a cool, dry place, away from direct sunlight and extreme temperatures. Moisture can cause rust on the paint cans, and extreme heat can dry out the paint or even trigger a fire with oil-based paint.

By following these labelling instructions, you will be able to effectively manage your paint containers and ensure the paint remains in good condition for future use.
