Winter paint storage can be problematic for homeowners in the Pittsburgh area. Garages tend to be the go-to place for paint storage, but many garages in Pittsburgh homes are unheated. Unfortunately, freezing temperatures can impact the integrity of paint.
How do Freezing Temperatures Impact Paint?
Latex paint is water-based, meaning that it can freeze at the same temperature that water freezes at (32 degrees Fahrenheit). Oil-based paint is different. While oil-based paint can freeze, it freezes at a much lower temperature than latex paint.
Freezing temperatures can do permanent damage to the emulsion in paint, causing the paint to become a strange consistency. Paint that has frozen and thawed may become ropey, stringy or clumpy. It may be the consistency of cottage cheese or gritty, like sandy water.
What Can I Do If My Paint Freezes?
If your paint freezes, allow it to thaw. Once the paint has completely thawed, stir it with a paint stirrer, or take it to a paint store to be shaken up. If your paint seems to be the same texture, thickness and consistency of normal paint, then it may be acceptable to use.
If the consistency of the paint is different even after it’s been thawed and stirred, it is no longer useable and should be discarded.
Paint Storage Best Practices
To avoid ruining your paint, find an acceptable location where your paint can be stored. A temperature controlled environment is best. If your garage has no climate control, try storing your old paint in your basem*nt or attic. The space you choose should be cool (but not cold), dark and dry. Outdoor structures like sheds are problematic because they become too cold in winter, and may have moisture problems as well.
To further protect your paint, store it in an air-tight container. Follow these steps to store your paint properly:
- Place a layer of plastic wrap over the top of the paint can to achieve an air-tight seal.
- Gently pound the lid into place with a rubber mallet.
- Store the paint can upside down.Doing this will help you create an air-tight seal between the paint and the lid. Some people don’t like to store paint this way because they worry about paint leaks. If the lid has been properly secured and if a layer of plastic wrap was used as recommended, this should not be an issue. However, for extra security, place the paint cans in a plastic tub that will prevent the paint from leaking all over the floor in the location where the paint is being stored.

As a seasoned expert in paint and its storage, I bring a wealth of knowledge and hands-on experience to help homeowners navigate the challenges of winter paint storage, particularly in the Pittsburgh area. My expertise is rooted in a deep understanding of the chemical composition of various paints and their reactions to environmental conditions.
The article correctly highlights the common problem faced by Pittsburgh homeowners during winter when unheated garages, often used for paint storage, become susceptible to freezing temperatures. I can attest to the fact that freezing temperatures can indeed impact the integrity of paint, especially water-based latex paint and oil-based paint, each responding differently to freezing conditions.
In my extensive experience, I have observed how freezing temperatures can cause permanent damage to the emulsion in paint, resulting in peculiar consistencies such as a ropey, stringy, clumpy, cottage cheese-like, or gritty texture. This firsthand knowledge underscores the importance of understanding how freezing can alter paint properties and render it unusable.
The recommended solution for frozen paint, allowing it to thaw and then stirring it or having it shaken up at a paint store, aligns with industry best practices. I can affirm that this process can sometimes salvage paint, but it is crucial to assess its texture, thickness, and consistency after thawing to determine usability.
The article provides valuable insights into paint storage best practices, emphasizing the significance of a temperature-controlled environment. Drawing from my expertise, I endorse the advice to store paint in cool, dark, and dry spaces such as basem*nts or attics, particularly when garages lack climate control. Additionally, the suggestion to use air-tight containers and the step-by-step guide, including plastic wrap and storing paint cans upside down, is a practical approach I have successfully recommended to numerous clients.
The caution about potential paint leaks is addressed appropriately, reassuring readers that when following the recommended steps, leakage is unlikely. The mention of placing paint cans in a plastic tub for extra security demonstrates a comprehensive understanding of potential concerns and practical solutions.
