Yes, pressure-treated wood can occasionally turn green due to certain preservatives, such as copper-based chemicals, used during the treatment process. These chemicals react with the wood, creating a greenish tint. The good news? It's temporary, and the color will fade over time. Staining or painting can also help hide any unwanted hues.

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.

Avoid using cleaning products that are abrasive or contain bleach or acidic components on composite decking to avoid discoloration. Early-generation Trex decking isn’t designed to handle pressure washer cleaning—and if you use them on second-generation boards, always use a low setting to avoid the risk of damage that can risk voiding your warranty.

Staining a deck with a rag is typically a better option than using a brush, as it helps the stain penetrate deeper into the wood. However, both brushes and rags are best reserved for detailed work because using these tools on an entire deck can require tediously crawling around on your hands and knees. A pad applicator, sprayer, or roller are preferred alternatives to applying stain over the majority of a deck. Use a rag for railings and other detailed work, and let the wood soak up as much of the stain as possible before wiping away drips or pools.
