How to Know if Paint Has Frozen

Most paint, when frozen and unthawed multiple times, will suffer irreversible damage. This is why most paint labels say in bold print, "Do Not Freeze." Some latex-based paints can be reused due to the anti-freeze additives in the paint. But this largely depends on how many times the latex paint has been frozen over time. While some latex paints can recover from being frozen, most paints will be ruined after they are thawed. If you know what to look for, you will be able to tell by examining the paint whether it's been frozen and is unsuitable for use.
