Vermont Natural Coatings Exterior Penetrating Water Proofer has a shelf life of 1 year unopened, and typically 6 months once opened if kept in a cool, dry place. Shelf life can vary depending on contamination and lid tightness. Because Vermont Natural Coatings Waterproofer contains no biocides or fungicides, spoiled product will develop a smell similar to rotten milk.
