How long will your can of deck stain last?
You might find that when you’ve finished that big staining project, that you’re left with a bunch of deck stain left over. Well, it would be a shame to throw it away, wouldn’t it? But if you intend to store it, then there are a few things you should know first. Your stains can stay usable if following these simple guidelines.
Unopened cans of deck stain
Unopened cans of deck stain – just like regular paint – have a shelf-life of up to 5 or 6 years before they start to deteriorate. So if you didn’t have time to start your project this year then there’s no reason to worry. You can use the paint any time that suits you within this timeframe. Make sure to store the deck stain in a temperature controlled room. Do not let the stain freeze.
In the case that your stain has been stored for a quite a while, it is recommended to take the can to a DIY store and have them use the shaker to help remix the stain and make sure it is ready for use.
Partially used cans
A more common problem is that you have already opened the can of stain, completed your deck and it is now only half-used. What can you do in this case? Most opened stains can last 12+ months if stored correctly with the lid tightly sealed. If the substance has contact with the air, the solvents will evaporate and you won’t be able to use your stain again so it’s important to ensure the container is sealed correctly.
Things to note when putting your deck stains away
The ideal environment for storing your deck stain is a cool, dry room with a steady temperature. You should also ensure that the stain cans are not exposed to direct sunlight.
Sometimes you are left with a few half-used cans of stain. In this case, you’re better off mixing them together.
The tips outlined in this article are there to help you save money. If you follow them, you will increase the shelf-life of your deck stains.
