You might have been in the situation where you purchased wood stain to put over one of your wood items but did not put the full container. Purchasing wood stains and the tools required to paint it could be costly, and if you’re like most of us, you’ll wish to get the utmost out of your buys by repurposing them.
Things To Remember
When you’re about to close the cap on the wood stain to preserve it or even decide whether to keep or toss it, you’re undoubtedly thinking: how long does wood stain last in a can? Wood stains have a three-year shelf life, though this might be shortened or extended based on how and where they’re kept.
It’s difficult to say how long a particular kind of wood stain will last in the can because most don’t include a “Used By” or “Best By” date like other goods. Producers of oil, water, and solvent-based wood stains, according to Rockler, claim that the stains have a three-year life span.
Three years is a good place to start if you’re searching for a benchmark, but a wood stain can last much longer with appropriate treatment and preservation. Several lacquer stains are renowned for persisting generations (yep, you saw it correctly!).
Do’s And Don’ts:
When exposed to severe temperatures, moisture, or ventilation, a wood conditioner could deteriorate. When the wood conditioner becomes poor, it splits into a fluid and a solid part, which would be evident. Your wood conditioner is still excellent and useable if it is still a single liquid.
This understanding is based on personal expertise. People usually didn’t utilize wood conditioner for 3-4 months after forgetting to replace the cap on it properly. It was a two-part disaster when they reopened it for the next assignment. They usually discarded the remainder and opened a new can because they had another one prepared to go.
What Is The Life Span?
Satin finishes and stains might fail sooner than gloss oil-based varnish, polyurethane, and Danish oil because pigments and flattening agents block the driers. Water-based paints and varnishes could last more than three years. Shellac, on the other hand, might go rancid in less than a year.
Oil-based varnishes have a one-year shelf life, whether opened or unopened. If the cans have been opened, they will last for one year, but unopened cans will last two to three years. If you use a water-based stain, it will last for one year if you open it and two years if you don’t.
What Causes Wood Stain To Go “Bad” In The Can?
While wood stains can last anywhere from three years to generations, there are a few major variables that might cause a stain to become “poor.” If you do any of the following, your wood stain may be more vulnerable to turning “poor” and lasting less time in the can.
- It’s open to the elements.
- It has been exposed to water.
- It’s kept in a place where temperature extremes, such as freezing and intense heat, are common.
- It is infected with bacteria.
After you’ve bought your preferred can of wood stain and applied it to your wood piece, there are a few things you could do to make sure it lasts longer in the can while you’re not utilizing it. You can still use it as long as it can churn it into a homogenous liquid. It’s all about the storage! If these items are shaken sometimes and kept in a cool environment, they will last longer.
