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.

The best paint for an older deck depends on the material and whether or not your deck already has a coat of paint. Generally, if your deck already has paint on it, you should choose the same type of paint when repainting the deck. For example, if an old deck has oil-based paint on it, stick with oil; if your deck has water-based paint, choose water-based paint. 

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.

You can paint over old paint on a concrete porch. For the best results, you should first clean the surface and remove as much paint as you can. A power washer is helpful here, but you’ll also want to scrape as much of the old paint away as possible. Then you should prime the porch before repainting it.
