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.

Apply a wood stain or sealant to properly maintain a wood deck railing and keep it looking new. Sealants protect wood from moisture and weathering. Regularly inspect the railing for loose screws, damaged balusters, and other signs of wear to make timely repairs. Routinely clean the railing using mild soap, water, and a soft bristle brush.

If your biggest concern is making sure your deck doesn’t show dirt, opt for a darker neutral color that blends in well with your surrounding landscape. A rich brown or dark grey are both good options that work with a variety of house colors. A high-quality acrylic paint is easy to clean and maintain, so it might be worth spending the money on.

If you don’t treat a cedar fence, it will turn from reddish brown to gray over time. You can keep the cedar from graying and retain its attractive, deep red color by sealing your cedar fence with a stain that keeps the wood’s oils in and serves as a barrier against the sun’s UV rays.
