How long does polyfilla last after you open it?

Once opened, Polyfilla typically lasts for about 12 months if stored properly in a cool, dry place and tightly sealed. However, its longevity may vary depending on the specific product and storage conditions. It's essential to check for signs of dryness or changes in texture before use, as these can indicate that the filler is no longer effective. Always refer to the manufacturer's guidelines for the best results.
