Can Exterior House Paint Handle Outdoor Storage? The Truth Revealed!

When it comes to home renovation projects, paint is an essential ingredient. But what happens when you have leftover paint or need to store it for future use? Can house paint be stored outside? The answer is a resounding yes, but with proper precautions and techniques. In this comprehensive guide, we’ll delve into the intricacies of storing house paint outside, ensuring its longevity and preserving its quality.

Understanding Paint Storage Requirements:

Before venturing into outdoor paint storage, it’s crucial to understand the ideal conditions for preserving paint‘s integrity. Paint, like a delicate work of art, requires a controlled environment to maintain its consistency, color, and performance.

• Temperature: Extreme temperatures, both hot and cold, can wreak havoc on paint. Ideal storage temperatures range between 50°F and 80°F (10°C and 27°C).

• Humidity: High humidity levels can cause paint to thicken and become unusable. Aim for a relative humidity below 50%.

• Light: Direct sunlight can cause paint to fade and deteriorate. Choose a storage location away from direct sunlight.

Preparing Paint for Outdoor Storage:

Before relegating paint cans to their outdoor storage space, a few preparatory steps are essential to ensure their survival.

1. Seal the Cans Properly: Ensure the paint cans are tightly sealed to prevent air and moisture from entering. If the original lid is damaged, consider using a plastic wrap or aluminum foil as a temporary seal.

2. Transfer to Smaller Containers: If storing large quantities of paint, consider transferring them to smaller, airtight containers. This helps minimize air exposure and reduces the risk of spoilage.

3. Label the Containers: Clearly label each container with the paint color, type, and date of storage. This organization will save you time and hassle when searching for a specific paint later.

Choosing the Right Outdoor Storage Location:

Selecting the appropriate outdoor storage location is paramount to preserving paint quality.

1. Sheltered Areas: Opt for sheltered areas like a covered porch, garage, or shed that offer protection from direct sunlight, rain, and snow.

2. Temperature Control: Ensure the chosen location maintains a consistent temperature within the ideal range (50°F to 80°F). Avoid areas prone to extreme temperature fluctuations.

3. Humidity Control: Choose a dry and well-ventilated space to minimize humidity levels. If necessary, consider using a dehumidifier to control humidity.

Additional Tips for Successful Outdoor Paint Storage:

1. Elevate the Paint: Place paint cans on pallets or shelves to elevate them off the ground, preventing moisture and pests from reaching them.

2. Use Waterproof Containers: If storing paint outdoors for extended periods, consider using waterproof containers to protect them from moisture and potential leaks.

3. Regular Inspections: Periodically inspect the stored paint for signs of spoilage, such as discoloration, thickening, or foul odor. Discard any paint that shows signs of deterioration.

Reviving Stored Paint:

Even with proper storage, paint can sometimes thicken or separate over time. Don’t despair! With a little TLC, you can often revive stored paint and restore it to its original glory.

1. Stir Thoroughly: Before using stored paint, stir it thoroughly to mix any settled pigments or additives. Use a paint stirrer or a power drill with a mixing attachment for larger containers.

2. Add Paint Thinner: If the paint has thickened, add a small amount of paint thinner (specific to the paint type) and mix thoroughly. Follow the manufacturer’s instructions for the recommended ratio of paint to thinner.

3. Strain the Paint: If there are lumps or particles in the paint, strain it through a fine-mesh strainer to remove any impurities.

What You Need to Know

1. How long can I store paint outside?

The longevity of stored paint depends on several factors, including the type of paint, storage conditions, and the effectiveness of the storage method. Generally, latex and acrylic paints can last up to two years when stored properly outdoors. Oil-based paints have a longer shelf life and can last up to five years.

2. Can I store paint in a plastic container?

Yes, you can store paint in plastic containers, but ensure they are airtight and made from high-quality plastic that won’t react with the paint. Some plastics may release chemicals that can contaminate the paint.

3. What is the best way to store paint brushes and rollers?

Clean paint brushes and rollers thoroughly after use and store them in a cool, dry place. Hang brushes upside down to prevent bristles from bending or deforming. Wrap rollers in plastic wrap or aluminum foil to keep them moist and prevent them from drying out.
