Using the paint booth to warm up the car is essential when spray painting in cold weather. The best temperature for spray painting is between 50°F and 90°F with a humidity of less than 85%. Anything outside of those conditions can pose a challenge and threaten the finished product. Never spray two-component urethane (2K) products below 55°F (13°C).
The chemical curing reaction stops below these temperatures and cannot be restarted. Make sure your 2K products are at least 60°F (16°C) before mixing and applying them. The temperature ranges for cold weather spray paint are generally considered to be 35 to 50 degrees Fahrenheit. Spray painting isn't a difficult task, but spray painting in cold weather can turn into a disaster, especially when painting the inside of a kitchen cabinet or car.
If you see lumps and the paint isn't smooth, then this is a sign that the paint can no longer be used and should be discarded. It is important to understand how low temperatures affect the application of paint and how they change the performance, characteristics and drying pattern of the paint. To ensure successful results, it is necessary to store the cans of spray paint and the items you're painting inside until you're ready to paint. Additionally, it is important to consider that excess moisture, ice or snow in the air cause the paint to take longer to dry.
