Shelf life of a deck stain?
The shelf life of deck stain depends on the type and brand of stain, as well as how the stain is stored. As a general rule, open cans of deck stain can be stored for up to 12 months and unopened cans of deck stain can be stored for up to 2-3 years depending on brand. Marrying like cans of deck stain creates fuller cans that have a lower chance of freezing or spoiling. Deck stain should be stored in a dry, cool, climate controlled area and will freeze if left in an unheated garage during winter.
