Wood stain does go bad, but it will last in the can for between three and six years, provided you use proper storage techniques. Storing wood stain in open containers or in extremely low or high temperatures will cause your wood stain to become unusable much more quickly. Water- and latex-based wood stains typically last for just two to four years, while oil-based wood stains can last for three to six years.

Staining or sealing a cedar deck or fence is highly recommended to extend its lifespan and protect it from the elements. While cedar is naturally resistant to mold and mildew, it is not impervious to damage from moisture, sun exposure, splintering, fading, and rot over time. Applying a protective finish creates a shield that preserves the wood's strength and appearance, potentially extending its life by five to 10 years.

When choosing a finish, it's helpful to understand the difference between a sealer and a stain. A sealer sits on top of the wood, whereas a combination stain and sealer soaks into the top layer. Because it penetrates the wood, a stain generally offers better protection against UV damage and rot and lasts significantly longer. For the best results that also preserve the wood's natural color, consider using a near-translucent stain.

To maintain protection, plan on reapplying the stain or sealer every two to three years, either as a DIY project or by hiring a professional.

For homes in areas with extreme weather, high heat, or intense sun exposure, high-quality acrylic paint is the best option. Acrylic paint is durable, resistant to both heat and cold, and provides a protective barrier with excellent UV resistance. For best results, look for acrylics that contain natural earth pigments, which are better suited for resisting sun damage. While oil-based paint is also durable, it can be prone to fading in high heat and can become too viscous to apply easily in cold temperatures. Additionally, choosing a neutral or light color like gray, beige, or white can help, as these colors absorb less heat than darker shades.

You don’t necessarily have to remove all the old paint before repainting your deck, but it’s best to remove as much as possible to ensure a smooth and long-lasting finish. Prioritize scraping off loose, peeling, or flaking paint, and sand down rough areas to create a smooth surface for the new paint to bond with.
