Yes, staining or sealing a cedar deck or fence is highly recommended to extend its lifespan, typically by five to 10 years. While cedar is naturally resistant to mold and mildew, it can still fall victim to moisture, sun exposure, and rot over time. Applying a treatment creates a protective shield that helps prevent splintering, fading, and decay, preserving the wood's strength and appearance. A combination stain and sealer often provides the best protection, as it soaks into the wood grain rather than just sitting on top. This offers superior defense against UV damage and rot and lasts longer than a sealer alone. To maintain the wood's natural look, consider using a near-translucent stain. You should plan to reapply the stain or sealer every two to three years.

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.

The longevity of paint on wood depends on factors like the quality of the paint, surface preparation, exposure to elements, and maintenance. Exterior paint on wood surfaces can last 5 to 15 years or more with proper care and maintenance. Interior paint tends to have a longer life span, often 10 years or more. Regular cleaning, touch-ups, and addressing any issues like peeling or cracking can extend the life of the paint. 

Stains penetrate wood best when it's cool and dry, so you want to avoid moisture. If the wood is wet upon application, or if it rains before the stain dries, the water will soak into the wood and displace the staining solution. This leads to a flaky and blotchy look, which is the opposite of a sumptuous even coat. Once the stain has fully cured, after about 3 days, rain shouldn’t cause you any problems.
