Get matched with top deck staining pros in Middleton, WI

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.

Applying a sealer or topcoat after staining wood is highly recommended, though not always strictly required. A sealer protects the wood from moisture, UV rays, and weather-related issues, which is especially important for outdoor surfaces like decks and fences. It also enhances the stain's durability, prevents fading over time, and gives the wood a cleaner, more professional-looking finish. For some indoor applications, a sealer may not be necessary, depending on the type of stain used and the level of protection needed. It's always best to check the stain manufacturer's recommendations and consider the wood's intended use and exposure when deciding whether to apply a sealer.

It’s necessary for paint to completely dry before exposure to rain, and that drying time varies by the type of paint used. Oil-based paint takes 6 to 8 hours to dry on average, meaning that’s the minimum time needed between the last brush stroke and the first raindrop. Latex paint dries faster at around 1 hour, and acrylic paint is even quicker, usually drying in about 30 minutes. If rain is in the forecast, check the paint manufacturer's details before laying on a new coat. 

Always sand a deck before repainting so the wood is smooth and ready for paint. While you do not need to fully remove paint before repainting, sanding helps remove any areas with weather and sun damage. Sanding also helps remove chipped or flaking paint and opens the wood pores to improve paint adhesion.
