Unopened cans of TWP stain have a shelf life of a few years and opened cans will keep for 1 to 2 years. An opened 5 Gallon pail will not reseal and should be used within a few weeks. If you will have stain leftover in your 5 Gallon Pail you can purchase an empty 1 Gallon Metal paint can from your hardware store. Transfer mixed product into the container and seal tightly. Also be sure to write on the can so you remember what you stored in it.
Other Tips to consider when storing TWP Stain
- TWP Should be stored in a cool dry place out of direct sunlight. Preferably between 50 and 70 degrees.
- Transfer leftover material from 5 Gallon pails to a 1 gallon metal paint can.
- Be sure to mix the stain well prior to re-use. You should use a drill mixer or bring the stain to a paint store to have them shake it.
- If the stain has started to solidify then it is no longer any good.
