The oil-based stain can be kept for 1 year if the cans have been opened, but the unopened cans will last 2 to 3 years. The water-based stain will last 1 year, if opened, and 2 years, if not opened. Oil-based varnishes will last 1 year, open or unopened. Manufacturers usually suggest a 3-year shelf life for wood dyes and finishes.
However, that period of time is simply an estimate; when stored in a temperature-controlled environment and the air in the can is minimized, stains and finishes on the wood can last much longer. For best results, store oil-based wood dye in a full or nearly full container. When there is an empty “headspace” above the liquid, the stain may gel or form a “skin” on top. When properly stored in sealed, nearly full containers, oil-based wood dyes and finishes have a lifespan of five years or more.
Be sure to label and date the remaining stain on the cover for future reference. Brushes, rollers and any other stain application tool can also be cleaned and stored for future use. Follow the cleaning instructions according to the stain label. Oil-based stains are cleaned with mineral alcohol, while soap and water are sufficient for water-based cover stains.
If you used a pump sprayer to apply the stain, be sure to clean it as well so you can use it later. Most cover stains last 1 to 2 years if stored: Follow these guidelines for storing a deck stain for future use and it will save you money in the long run. There are other considerations that will help determine how long wood stain can last before it needs to be discarded and stopped being used. Once you are done with the stain and prepared it for storage, combine all the excess stain in as few containers as possible.
There are a few important things to know in order to know how long wood dye lasts in the tin. Once you've invested time and money to tint your deck or other outdoor wooden surface, it makes sense to save the rest of the terrace dye for future use. While manufacturers indicate that wood dyes have a lifespan of 3 years, keep in mind that they benefit from throwing away a product and having to buy it again. In addition, wood dye should be stored outside areas where it may be exposed to fire hazards.
Wood dyes and finishes should not be stored in garages, as most garages are not temperature-controlled locations. Stir the dye to mix the pigments that have sunk into the bottom of the can, then take some scrap wood and apply the dye to the wood. While the 3-year shelf life is standard for most wood dyes and finishes, some products have different recommendations. There are a few ways to tell if it's time to finally put off wood dye and throw it away, instead of keeping it.
As if wood dye didn't already have enough benefits, it can also be a protector for wood, protecting it from the sun's rays and other damage, such as insects. An important component of wood dyes and finishes are mineral alcohols, which are a petroleum-based product used as a diluent. In the event that the stain has been stored for quite some time, it is recommended to take the can to a DIY store and have them use the shaker to help mix the stain and make sure it is ready for use. Unlike oil-based dyes, water-based wood dyes must be kept at temperatures above 32 degrees Fahrenheit.
Varnish stains share most of the characteristics of oil stains, except for the fact that varnish stains only use varnish as a binder. .
