Storing paint in the garage is a good way to keep it away from children and pets, but cold weather can harm its quality. When temperatures drop, paint can separate, thicken, harden, or clump, making it difficult to use later on. So, should you move your paint indoors during winter?
The answer isn’t always straightforward. Freezing temperatures can ruin paint, but not everyone faces this issue. Here are some guidelines on when to bring paint inside, how to assess damage, and what to do if your paint has been exposed to winter conditions.
**Recommended Storage Temperatures**
Paint is sensitive to temperature fluctuations, and freezing can render it unusable. The ideal storage temperature varies by manufacturer, so check the label or online resources for specifics. For example, Benjamin Moore suggests storing paint between 60°F and 80°F.
When temperatures dip below freezing (32°F), latex and water-based paints can freeze, causing water separation and rendering the paint lumpy and unusable. While oil-based paints are more resilient, they can also suffer changes in texture that affect their performance.
**Winter Storage Recommendations**
Although many people store paint in the garage, extreme winter conditions are not suitable. If your garage isn’t climate-controlled, consider storing paint in a well-insulated and ventilated area like the basement, attic, or utility closet. Optimal conditions are dark, cool, and dry (not cold).
To minimize the risk of winter damage, ensure paint containers are airtight. Use plastic wrap over the can before sealing it tightly with a rubber mallet and storing it upside down. If you must leave paint in a cold garage, place cans in insulated containers or wrap them in insulation or blankets to shield them from temperature fluctuations. A portable heater or heating pad can help maintain a stable temperature. Store paint cans on shelves or pallets to prevent direct contact with cold floors, and check them regularly for signs of freezing.
**Assessing Paint Damage**
If water-based paint has separated, or if consistency has changed, it may be damaged. Thaw and shake the paint, then test it on cardboard. Paint that’s no longer spreadable or doesn’t adhere is likely unusable. Stringy, sandy, or clumpy textures, as well as strange odors, indicate irreparable damage.
**Restoring Damaged Paint**
While paint exposed to freezing temperatures may be irreparable, some methods can help salvage it.
Dealing with frozen paint can be a challenge. To thaw it properly, allow the paint to melt slowly at room temperature indoors. Avoid using heaters or hot water to speed up the process. Once melted, thoroughly stir the paint using a paint mixer to blend the components back together. If needed, you can also take the paint to professionals at a paint store for mechanical shaking. Stirring or shaking can help restore the texture, thickness, and consistency of the paint. If the paint remains lumpy after stirring, strain it through a fine mesh to remove clumps. Additionally, consider using paint conditioners such as Floetrol for water-based paints or Penetrol for oil-based paints, which may help restore the paint’s adhesive properties. Always test the paint on a small area to ensure it performs well before using it on a larger project. If quality is essential for your project, it might be best to purchase new paint.
Regarding storing paint during winter, it is not recommended to store it in a non-climate-controlled garage. Instead, store paint in areas that maintain the recommended temperature ranges to prevent damage and avoid unnecessary replacement costs. Regularly check your paint containers for any signs of damage from extreme temperatures. If the paint is no longer usable, dispose of it properly and safely to minimize waste.
